Three wild technologies about to change health care
When I was a child, I watched syndicated episodes of the original “Star Trek.” I was dazzled by the space travel, sure, but also the medical technology.
A handheld “tricorder” detected diseases, while an intramuscular injector (“hypospray”) could treat them. Sickbay “biobeds” came with real-time health monitors that looked futuristic at the time but seem primitive today.
Such visions inspired a lot of us kids to pursue science. Little did we know the real-life advances many of us would see in our lifetimes.
Artificial intelligence helping to spot disease, robots performing surgery, even video calls between doctor and patient – all these once sounded fantastical but now happen in clinical care.
Now, in the 23rd year of the 21st century, you might not believe wht we’ll be capable of next. Three especially wild examples are moving closer to clinical reality.
Human hibernation
Captain America, Han Solo, and “Star Trek” villain Khan – all were preserved at low temperatures and then revived, waking up alive and well months, decades, or centuries later. These are fictional examples, to be sure, but the science they’re rooted in is real.
(In one extreme case, a climber survived after almost 9 hours of efforts to revive him.)
Useful for a space traveler? Maybe not. But it’s potentially huge for someone with life-threatening injuries from a car accident or a gunshot wound.
That’s the thinking behind a breakthrough procedure that came after decades of research on pigs and dogs, now in a clinical trial. The idea: A person with massive blood loss whose heart has stopped is injected with an ice-cold fluid, cooling them from the inside, down to about 50° F.
Doctors already induce more modest hypothermia to protect the brain and other organs after cardiac arrest and during surgery on the aortic arch (the main artery carrying blood from the heart).
But this experimental procedure – called emergency preservation and resuscitation (EPR) – goes far beyond that, dramatically “decreasing the body’s need for oxygen and blood flow,” says Samuel Tisherman, MD, a trauma surgeon at the University of Maryland Medical Center and the trial’s lead researcher. This puts the patient in a state of suspended animation that “could buy time for surgeons to stop the bleeding and save more of these patients.”
The technique has been done on at least six patients, though none were reported to survive. The trial is expected to include 20 people by the time it wraps up in December, according to the listing on the U.S. clinical trials database. Though given the strict requirements for candidates (emergency trauma victims who are not likely to survive), one can’t exactly rely on a set schedule.
Still, the technology is promising. Someday we may even use it to keep patients in suspended animation for months or years, experts predict, helping astronauts through decades-long spaceflights, or stalling death in sick patients awaiting a cure.
Artificial womb
Another sci-fi classic: growing human babies outside the womb. Think the fetus fields from “The Matrix,” or the frozen embryos in “Alien: Covenant.”
In 1923, British biologist J.B.S. Haldane coined a term for that – ectogenesis. He predicted that 70% of pregnancies would take place, from fertilization to birth, in artificial wombs by 2074. That many seems unlikely, but the timeline is on track.
Developing an embryo outside the womb is already routine in in vitro fertilization. And technology enables preterm babies to survive through much of the second half of gestation. Normal human pregnancy is 40 weeks, and the youngest preterm baby ever to survive was 21 weeks and 1 day old, just a few days younger than a smattering of others who lived.
The biggest obstacle for babies younger than that is lung viability. Mechanical ventilation can damage the lungs and lead to a chronic (sometimes fatal) lung disease known as bronchopulmonary dysplasia. Avoiding this would mean figuring out a way to maintain fetal circulation – the intricate system that delivers oxygenated blood from the placenta to the fetus via the umbilical cord. Researchers at Children’s Hospital of Philadelphia have done this using a fetal lamb.
The key to their invention is a substitute placenta: an oxygenator connected to the lamb’s umbilical cord. Tubes inserted through the umbilical vein and arteries carry oxygenated blood from the “placenta” to the fetus, and deoxygenated blood back out. The lamb resides in an artificial, fluid-filled amniotic sac until its lungs and other organs are developed.
Fertility treatment could benefit, too. “An artificial womb may substitute in situations in which a gestational carrier – surrogate – is indicated,” says Paula Amato, MD, a professor of obstetrics and gynecology at Oregon Health and Science University, Portland. (Dr. Amato is not involved in the CHOP research.) For example: when the mother is missing a uterus or can’t carry a pregnancy safely.
No date is set for clinical trials yet. But according to the research, the main difference between human and lamb may come down to size. A lamb’s umbilical vessels are larger, so feeding in a tube is easier. With today’s advances in miniaturizing surgical methods, that seems like a challenge scientists can overcome.
Messenger RNA therapeutics
Back to “Star Trek.” The hypospray injector’s contents could cure just about any disease, even one newly discovered on a strange planet. That’s not unlike messenger RNA (mRNA) technology, a breakthrough that enabled scientists to quickly develop some of the first COVID-19 vaccines.
But vaccines are just the beginning of what this technology can do.
A whole field of immunotherapy is emerging that uses mRNA to deliver instructions to produce chimeric antigen receptor–modified immune cells (CAR-modified immune cells). These cells are engineered to target diseased cells and tissues, like cancer cells and harmful fibroblasts (scar tissue) that promote fibrosis in, for example, the heart and lungs.
The field is bursting with rodent research, and clinical trials have started for treating some advanced-stage malignancies.
Actual clinical use may be years away, but if all goes well, these medicines could help treat or even cure the core medical problems facing humanity. We’re talking cancer, heart disease, neurodegenerative disease – transforming one therapy into another by simply changing the mRNA’s “nucleotide sequence,” the blueprint containing instructions telling it what to do, and what disease to attack.
As this technology matures, we may start to feel as if we’re really on “Star Trek,” where Dr. Leonard “Bones” McCoy pulls out the same device to treat just about every disease or injury.

A new (old) drug joins the COVID fray, and guess what? It works
This transcript has been edited for clarity.
Welcome to Impact Factor, your weekly dose of commentary on a new medical study. I’m Dr F. Perry Wilson of the Yale School of Medicine.
At this point, with the monoclonals found to be essentially useless, we are left with remdesivir with its modest efficacy and Paxlovid, which, for some reason, people don’t seem to be taking.
Part of the reason the monoclonals have failed lately is because of their specificity; they are homogeneous antibodies targeted toward a very specific epitope that may change from variant to variant. We need a broader therapeutic, one that has activity across all variants — maybe even one that has activity against all viruses? We’ve got one. Interferon.
The first mention of interferon as a potential COVID therapy was at the very start of the pandemic, so I’m sort of surprised that the first large, randomized trial is only being reported now in the New England Journal of Medicine.
Before we dig into the results, let’s talk mechanism. This is a trial of interferon-lambda, also known as interleukin-29.
The lambda interferons were only discovered in 2003. They differ from the more familiar interferons only in their cellular receptors; the downstream effects seem quite similar. As opposed to the cellular receptors for interferon alfa, which are widely expressed, the receptors for lambda are restricted to epithelial tissues. This makes it a good choice as a COVID treatment, since the virus also preferentially targets those epithelial cells.
In this study, 1,951 participants from Brazil and Canada, but mostly Brazil, with new COVID infections who were not yet hospitalized were randomized to receive 180 mcg of interferon lambda or placebo.
This was a relatively current COVID trial, as you can see from the participant characteristics. The majority had been vaccinated, and nearly half of the infections were during the Omicron phase of the pandemic.
If you just want to cut to the chase, interferon worked.
The primary outcome – hospitalization or a prolonged emergency room visit for COVID – was 50% lower in the interferon group.
Key secondary outcomes, including death from COVID, were lower in the interferon group as well. These effects persisted across most of the subgroups I was looking out for.
Interferon seemed to help those who were already vaccinated and those who were unvaccinated. There’s a hint that it works better within the first few days of symptoms, which isn’t surprising; we’ve seen this for many of the therapeutics, including Paxlovid. Time is of the essence. Encouragingly, the effect was a bit more pronounced among those infected with Omicron.
Of course, if you have any experience with interferon, you know that the side effects can be pretty rough. In the bad old days when we treated hepatitis C infection with interferon, patients would get their injections on Friday in anticipation of being essentially out of commission with flu-like symptoms through the weekend. But we don’t see much evidence of adverse events in this trial, maybe due to the greater specificity of interferon lambda.
Putting it all together, the state of play for interferons in COVID may be changing. To date, the FDA has not recommended the use of interferon alfa or -beta for COVID-19, citing some data that they are ineffective or even harmful in hospitalized patients with COVID. Interferon lambda is not FDA approved and thus not even available in the United States. But the reason it has not been approved is that there has not been a large, well-conducted interferon lambda trial. Now there is. Will this study be enough to prompt an emergency use authorization? The elephant in the room, of course, is Paxlovid, which at this point has a longer safety track record and, importantly, is oral. I’d love to see a head-to-head trial. Short of that, I tend to be in favor of having more options on the table.
Dr. Perry Wilson is associate professor, department of medicine, and director, Clinical and Translational Research Accelerator, at Yale University, New Haven, Conn. He disclosed no relevant conflicts of interest.

Pound of flesh buys less prison time
Pound of flesh buys less prison time
We should all have more Shakespeare in our lives. Yeah, yeah, Shakespeare is meant to be played, not read, and it can be a struggle to herd teenagers through the Bard’s interesting and bloody tragedies, but even a perfunctory reading of “The Merchant of Venice” would hopefully have prevented the dystopian nightmare Massachusetts has presented us with today.
The United States has a massive shortage of donor organs. This is an unfortunate truth. So, to combat this issue, a pair of Massachusetts congresspeople have proposed HD 3822, which would allow prisoners to donate organs and/or bone marrow (a pound of flesh, so to speak) in exchange for up to a year in reduced prison time. Yes, that’s right. Give up pieces of yourself and the state of Massachusetts will deign to reduce your long prison sentence.
Oh, and before you dismiss this as typical Republican antics, the bill was sponsored by two Democrats, and in a statement one of them hoped to address racial disparities in organ donation, as people of color are much less likely to receive organs. Never mind that Black people are imprisoned at a much higher rate than Whites.
Yeah, this whole thing is what people in the business like to call an ethical disaster.
Fortunately, the bill will likely never be passed and it’s probably illegal anyway. A federal law from 1984 (how’s that for a coincidence) prevents people from donating organs for use in human transplantation in exchange for “valuable consideration.” In other words, you can’t sell your organs for profit, and in this case, reducing prison time would probably count as valuable consideration in the eyes of the courts.
Oh, and in case you’ve never read Merchant of Venice, Shylock, the character looking for the pound of flesh as payment for a debt? He’s the villain. In fact, it’s pretty safe to say that anyone looking to extract payment from human dismemberment is probably the bad guy of the story. Apparently that wasn’t clear.
How do you stop a fungi? With a deadly guy
Thanks to the new HBO series “The Last of Us,” there’s been a lot of talk about the upcoming fungi-pocalypse, as the show depicts the real-life “zombie fungus” Cordyceps turning humans into, you know, zombies.
No need to worry, ladies and gentleman, because science has discovered a way to turn back the fungal horde. A heroic, and environmentally friendly, alternative to chemical pesticides “in the fight against resistant fungi [that] are now resistant to antimycotics – partly because they are used in large quantities in agricultural fields,” investigators at the Leibniz Institute for Natural Product Research and Infection Biology in Jena, Germany, said in a written statement.
We are, of course, talking about Keanu Reeves. Wait a second. He’s not even in “The Last of Us.” Sorry folks, we are being told that it really is Keanu Reeves. Our champion in the inevitable fungal pandemic is movie star Keanu Reeves. Sort of. It’s actually keanumycin, a substance produced by bacteria of the genus Pseudomonas.
Really? Keanumycin? “The lipopeptides kill so efficiently that we named them after Keanu Reeves because he, too, is extremely deadly in his roles,” lead author Sebastian Götze, PhD, explained.
Dr. Götze and his associates had been working with pseudomonads for quite a while before they were able to isolate the toxins responsible for their ability to kill amoebae, which resemble fungi in some characteristics. When then finally tried the keanumycin against gray mold rot on hydrangea leaves, the intensely contemplative star of “The Matrix” and “John Wick” – sorry, wrong Keanu – the bacterial derivative significantly inhibited growth of the fungus, they said.
Additional testing has shown that keanumycin is not highly toxic to human cells and is effective against fungi such as Candida albicans in very low concentrations, which makes it a good candidate for future pharmaceutical development.
To that news there can be only one response from the substance’s namesake.
High fat, bye parasites
Fat. Fat. Fat. Seems like everyone is trying to avoid it these days, but fat may be good thing when it comes to weaseling out a parasite.
The parasite in this case is the whipworm, aka Trichuris trichiura. You can find this guy in the intestines of millions of people, where it causes long-lasting infections. Yikes … Researchers have found that the plan of attack to get rid of this invasive species is to boost the immune system, but instead of vitamin C and zinc it’s fat they’re pumping in. Yes, fat.
The developing countries with poor sewage that are at the highest risk for contracting parasites such as this also are among those where people ingest cheaper diets that are generally higher in fat. The investigators were interested to see how a high-fat diet would affect immune responses to the whipworms.
And, as with almost everything else, the researchers turned to mice, which were introduced to a closely related species, Trichuris muris.
A high-fat diet, rather than obesity itself, increases a molecule on T-helper cells called ST2, and this allows an increased T-helper 2 response, effectively giving eviction notices to the parasites in the intestinal lining.
To say the least, the researchers were surprised since “high-fat diets are mostly associated with increased pathology during disease,” said senior author Richard Grencis, PhD, of the University of Manchester (England), who noted that ST2 is not normally triggered with a standard diet in mice but the high-fat diet gave it a boost and an “alternate pathway” out.
Now before you start ordering extra-large fries at the drive-through to keep the whipworms away, the researchers added that they “have previously published that weight loss can aid the expulsion of a different gut parasite worm.” Figures.
Once again, though, signs are pointing to the gut for improved health.
Pound of flesh buys less prison time
We should all have more Shakespeare in our lives. Yeah, yeah, Shakespeare is meant to be played, not read, and it can be a struggle to herd teenagers through the Bard’s interesting and bloody tragedies, but even a perfunctory reading of “The Merchant of Venice” would hopefully have prevented the dystopian nightmare Massachusetts has presented us with today.
The United States has a massive shortage of donor organs. This is an unfortunate truth. So, to combat this issue, a pair of Massachusetts congresspeople have proposed HD 3822, which would allow prisoners to donate organs and/or bone marrow (a pound of flesh, so to speak) in exchange for up to a year in reduced prison time. Yes, that’s right. Give up pieces of yourself and the state of Massachusetts will deign to reduce your long prison sentence.
Oh, and before you dismiss this as typical Republican antics, the bill was sponsored by two Democrats, and in a statement one of them hoped to address racial disparities in organ donation, as people of color are much less likely to receive organs. Never mind that Black people are imprisoned at a much higher rate than Whites.
Yeah, this whole thing is what people in the business like to call an ethical disaster.
Fortunately, the bill will likely never be passed and it’s probably illegal anyway. A federal law from 1984 (how’s that for a coincidence) prevents people from donating organs for use in human transplantation in exchange for “valuable consideration.” In other words, you can’t sell your organs for profit, and in this case, reducing prison time would probably count as valuable consideration in the eyes of the courts.
Oh, and in case you’ve never read Merchant of Venice, Shylock, the character looking for the pound of flesh as payment for a debt? He’s the villain. In fact, it’s pretty safe to say that anyone looking to extract payment from human dismemberment is probably the bad guy of the story. Apparently that wasn’t clear.
How do you stop a fungi? With a deadly guy
Thanks to the new HBO series “The Last of Us,” there’s been a lot of talk about the upcoming fungi-pocalypse, as the show depicts the real-life “zombie fungus” Cordyceps turning humans into, you know, zombies.
No need to worry, ladies and gentleman, because science has discovered a way to turn back the fungal horde. A heroic, and environmentally friendly, alternative to chemical pesticides “in the fight against resistant fungi [that] are now resistant to antimycotics – partly because they are used in large quantities in agricultural fields,” investigators at the Leibniz Institute for Natural Product Research and Infection Biology in Jena, Germany, said in a written statement.
We are, of course, talking about Keanu Reeves. Wait a second. He’s not even in “The Last of Us.” Sorry folks, we are being told that it really is Keanu Reeves. Our champion in the inevitable fungal pandemic is movie star Keanu Reeves. Sort of. It’s actually keanumycin, a substance produced by bacteria of the genus Pseudomonas.

Maternal COVID-19 vaccine curbs infant infection
a new study shows.
Previous research has confirmed that COVID-19 neutralizing antibodies following maternal vaccination or maternal COVID-19 infection are present in umbilical cord blood, breast milk, and infant serum specimens, wrote Sarah C.J. Jorgensen, PharmD, MPH, of the University of Toronto, and colleagues in their article published in The BMJ.
In the study, the researchers identified maternal and newborn pairs using administrative databases from Canada. The study population included 8,809 infants aged younger than 6 months who were born between May 7, 2021, and March 31, 2022, and who underwent testing for COVID-19 between May 7, 2021, and September 5, 2022.
Maternal vaccination with the primary COVID-19 mRNA monovalent vaccine series was defined as two vaccine doses administered up to 14 days before delivery, with at least one of the doses after the conception date.
Maternal vaccination with the primary series plus one booster was defined as three doses administered up to 14 days before delivery, with at least one of these doses after the conception date.
The primary outcome was the presence of delta or omicron COVID-19 infection or hospital admission of the infants.
The study population included 99 COVID-19 cases with the delta variant (with 4,365 controls) and 1,501 cases with the omicron variant (with 4,847 controls).
Overall, the vaccine effectiveness of maternal doses was 95% against delta infection and 45% against omicron.
The effectiveness against hospital admission in cases of delta and omicron variants were 97% and 53%, respectively.
The effectiveness of three doses was 73% against omicron infant infection and 80% against omicron-related infant hospitalization. Data were not available for the effectiveness of three doses against the delta variant.
The effectiveness of two doses of vaccine against infant omicron infection was highest when mothers received the second dose during the third trimester of pregnancy, compared with during the first trimester or second trimester (53% vs. 47% and 53% vs. 37%, respectively).
Vaccine effectiveness with two doses against infant infection from omicron was highest in the first 8 weeks of life (57%), then decreased to 40% among infants after 16 weeks of age.
Although the study was not designed to assess the mechanism of action of the impact of maternal vaccination on infants, the current study results were consistent with other recent studies showing a reduction in infections and hospitalizations among infants whose mothers received COVID-19 vaccines during pregnancy, the researchers wrote in their discussion.
The findings were limited by several factors including the potential unmeasured confounders not available in databases, such as whether infants were breastfed, the researchers noted. Other limitations included a lack of data on home test results and the inability to assess the waning impact of the vaccine effectiveness against the delta variant because of the small number of delta cases, they said. However, the results suggest that the mRNA COVID-19 vaccine during pregnancy was moderately to highly effective for protection against omicron and delta infection and infection-related hospitalization – especially during the first 8 weeks of life.
Effectiveness is encouraging, but updates are needed
The effectiveness of maternal vaccination to prevent COVID-19 infection and related hospitalizations in infants is promising, especially since those younger than 6 months have no other source of vaccine protection against COVID-19 infection, wrote Dana Danino, MD, of Soroka University Medical Center, Israel, and Ilan Youngster, MD, of Shamir Medical Center, Israel, in an accompanying editorial also published in The BMJ.
They also noted that maternal vaccination during pregnancy is an established method of protecting infants from infections such as influenza and pertussis.
Data from previous studies show that most infants whose mothers were vaccinated against COVID-19 during pregnancy retained maternal antibodies at 6 months, “but evidence for protection against neonatal COVID-19 infection has been deficient,” they said.
The current study findings support the value of vaccination during pregnancy, and the findings were strengthened by the large study population, the editorialists wrote. However, whether the same effectiveness holds for other COVID-19 strains such as BQ.1, BQ.1.1, BF.7, XBB, and XBB.1 remains unknown, they said.
Other areas in need of exploration include the optimal timing of vaccination during pregnancy, the protective effects of a bivalent mRNA vaccine (vs. the primary monovalent vaccine in the current study), and the potential benefits of additional boosters, they added.
“Although Jorgenson and colleagues’ study reinforces the value of maternal vaccination against COVID-19 during pregnancy, more studies are needed to better inform vaccination recommendations in an evolving landscape of new SARS-CoV-2 strains and novel vaccines,” the editorialists concluded.
The study was supported by ICES, which is funded by an annual grant from the Ontario Ministry of Health and the Ministry of Long-term Care; the study also received funding from the Canadian Immunization Research Network and the Public Health Agency of Canada. Dr. Jorgensen and the editorialists had no financial conflicts to disclose.

FROM THE BMJ
Acute cardiac events common during COVID hospitalization
particularly among those with underlying heart disease, and are associated with more severe disease outcomes, a new study suggests.
“We expected to see acute cardiac events occurring among adults hospitalized with COVID-19 but were surprised by how frequently they occurred,” Rebecca C. Woodruff, PhD, MPH, of the U.S. Centers for Disease Control and Prevention, Atlanta, told this news organization.
Overall, she said, “about 1 in 10 adults experienced an acute cardiac event – including heart attacks and acute heart failure – while hospitalized with COVID-19, and this included people with no preexisting heart disease.”
However, she added, “about a quarter of those with underlying heart disease had an acute cardiac event. These patients tended to experience more severe disease outcomes relative to patients hospitalized with COVID-19 who did not experience an acute cardiac event.”
The findings might be relevant to hospitalizations for other viral diseases, “though we can’t say for sure,” she noted. “This study was modeled off a previous study conducted before the COVID-19 pandemic among adults hospitalized with influenza. About 11.7% of [those] adults experienced an acute cardiac event, which was a similar percentage as what we found among patients hospitalized with COVID-19.”
The study was published online in the Journal of the American College of Cardiology.
Underlying cardiac disease key
Dr. Woodruff and colleagues analyzed medical records on a probability sample of 8,460 adults hospitalized with SARS-CoV-2 infection identified from 99 U.S. counties in 14 U.S. states (about 10% of the United States population) from January to November 2021.
Among participants, 11.4% had an acute cardiac event during their hospitalization. The median age was 69 years; 56.5% were men; 48.7%, non-Hispanic White; 33.6%, non-Hispanic Black; 7.4%, Hispanic; and 7.1%, non-Hispanic Asian or Pacific Islander.
As indicated, the prevalence was higher among those with underlying cardiac disease (23.4%), compared with those without (6.2%).
Acute ischemic heart disease (5.5%) and acute heart failure (5.4%) were the most prevalent events; 0.3% of participants had acute myocarditis or pericarditis.
Risk factors varied, depending on underlying cardiac disease status. Those who experienced one or more acute cardiac events had a greater risk for intensive care unit admission (adjusted risk ratio,1.9) and in-hospital death (aRR, 1.7) versus those who did not.
In multivariable analyses, the risk of experiencing acute heart failure was significantly greater among men (aRR, 1.5) and among those with a history of congestive heart failure (aRR, 13.5), atrial fibrillation (aRR, 1.6) or hypertension (aRR,1.3).
Among patients who experienced one or more acute cardiac events, 39.2% required an intensive care unit stay for a median of 5 days. Approximately 22.4% required invasive mechanical ventilation or extracorporeal membrane oxygenation, and 21.1% died while hospitalized.
“Persons at greater risk for experiencing acute cardiac events during COVID-19–associated hospitalizations might benefit from more intensive clinical evaluation and monitoring during hospitalization,” the authors conclude.
The team currently is taking a closer look at acute myocarditis among patients hospitalized with COVID-19, Dr. Woodruff said. Preliminary results were presented at the 2022 annual scientific sessions of the American Heart Association and a paper is forthcoming.
Contemporary data needed
James A. de Lemos, MD, co-chair of the American Heart Association’s COVID-19 CVD Registry Steering Committee and professor of medicine at the University of Texas Southwestern Medical Center, Dallas, said the findings mirror his team’s clinical experience in 2020 and 2021 and echo what was seen in the AHA COVID registry: that is, a 0.3% rate of myocarditis.
“The major caveat is that [the findings] may not be generalizable to contemporary COVID infection, both due to changing viral variants and higher levels of immunity in the population,” he said.
“Rates of COVID hospitalization are markedly lower with the current dominant variants, and we would expect the cardiac risk to be lower as well. I would like to see more contemporary data with current variants, particularly focused on higher risk patients with cardiovascular disease,” Dr. de Lemos added.
In a related editorial, George A. Mensa, MD, of the National Heart, Lung, and Blood Institute in Bethesda, Md., and colleagues suggest that the broader impact of the COVID-19 pandemic on human health remains “incompletely examined.”
“The impact of COVID-19 on cardiovascular mortality, in particular, appears to have varied widely, with no large increases seen in a number of the most developed countries but marked increases in hypertensive heart disease mortality seen in the United States in 2021,” they conclude. “The potential contribution of COVID-19 to these deaths, either directly or indirectly, remains to be determined.”
No commercial funding or relevant financial relationships were reported.

Dr. Woodruff and colleagues analyzed medical records on a probability sample of 8,460 adults hospitalized with SARS-CoV-2 infection identified from 99 U.S. counties in 14 U.S. states (about 10% of the United States population) from January to November 2021.
Among participants, 11.4% had an acute cardiac event during their hospitalization. The median age was 69 years; 56.5% were men; 48.7%, non-Hispanic White; 33.6%, non-Hispanic Black; 7.4%, Hispanic; and 7.1%, non-Hispanic Asian or Pacific Islander.
As indicated, the prevalence was higher among those with underlying cardiac disease (23.4%), compared with those without (6.2%).
Acute ischemic heart disease (5.5%) and acute heart failure (5.4%) were the most prevalent events; 0.3% of participants had acute myocarditis or pericarditis.
Risk factors varied, depending on underlying cardiac disease status. Those who experienced one or more acute cardiac events had a greater risk for intensive care unit admission (adjusted risk ratio,1.9) and in-hospital death (aRR, 1.7) versus those who did not.
In multivariable analyses, the risk of experiencing acute heart failure was significantly greater among men (aRR, 1.5) and among those with a history of congestive heart failure (aRR, 13.5), atrial fibrillation (aRR, 1.6) or hypertension (aRR,1.3).
Among patients who experienced one or more acute cardiac events, 39.2% required an intensive care unit stay for a median of 5 days. Approximately 22.4% required invasive mechanical ventilation or extracorporeal membrane oxygenation, and 21.1% died while hospitalized.
“Persons at greater risk for experiencing acute cardiac events during COVID-19–associated hospitalizations might benefit from more intensive clinical evaluation and monitoring during hospitalization,” the authors conclude.
The team currently is taking a closer look at acute myocarditis among patients hospitalized with COVID-19, Dr. Woodruff said. Preliminary results were presented at the 2022 annual scientific sessions of the American Heart Association and a paper is forthcoming.
Contemporary data needed
James A. de Lemos, MD, co-chair of the American Heart Association’s COVID-19 CVD Registry Steering Committee and professor of medicine at the University of Texas Southwestern Medical Center, Dallas, said the findings mirror his team’s clinical experience in 2020 and 2021 and echo what was seen in the AHA COVID registry: that is, a 0.3% rate of myocarditis.
“The major caveat is that [the findings] may not be generalizable to contemporary COVID infection, both due to changing viral variants and higher levels of immunity in the population,” he said.
“Rates of COVID hospitalization are markedly lower with the current dominant variants, and we would expect the cardiac risk to be lower as well. I would like to see more contemporary data with current variants, particularly focused on higher risk patients with cardiovascular disease,” Dr. de Lemos added.
In a related editorial, George A. Mensa, MD, of the National Heart, Lung, and Blood Institute in Bethesda, Md., and colleagues suggest that the broader impact of the COVID-19 pandemic on human health remains “incompletely examined.”
“The impact of COVID-19 on cardiovascular mortality, in particular, appears to have varied widely, with no large increases seen in a number of the most developed countries but marked increases in hypertensive heart disease mortality seen in the United States in 2021,” they conclude. “The potential contribution of COVID-19 to these deaths, either directly or indirectly, remains to be determined.”
No commercial funding or relevant financial relationships were reported.

particularly among those with underlying heart disease, and are associated with more severe disease outcomes, a new study suggests.
“We expected to see acute cardiac events occurring among adults hospitalized with COVID-19 but were surprised by how frequently they occurred,” Rebecca C. Woodruff, PhD, MPH, of the U.S. Centers for Disease Control and Prevention, Atlanta, told this news organization.
Overall, she said, “about 1 in 10 adults experienced an acute cardiac event – including heart attacks and acute heart failure – while hospitalized with COVID-19, and this included people with no preexisting heart disease.”
However, she added, “about a quarter of those with underlying heart disease had an acute cardiac event. These patients tended to experience more severe disease outcomes relative to patients hospitalized with COVID-19 who did not experience an acute cardiac event.”
The findings might be relevant to hospitalizations for other viral diseases, “though we can’t say for sure,” she noted. “This study was modeled off a previous study conducted before the COVID-19 pandemic among adults hospitalized with influenza. About 11.7% of [those] adults experienced an acute cardiac event, which was a similar percentage as what we found among patients hospitalized with COVID-19.”

What is the psychological cost of performing CPR?
One year ago, as the sun was setting on a late fall day, Andrés Snitcofsky, a 40-year-old designer from Buenos Aires, Argentina, heard harrowing cries for help. It was the niece and the wife of one of his neighbors: a man in his 60s who the women had found “passed out” in the bedroom. “I did CPR for 5 minutes straight until a friend of the victim came in and asked me to stop, telling me that the man had probably been dead for 2 or 3 hours already. But I had no idea because I’d never seen a dead body before,” Mr. Snitcofsky told this news organization. A few minutes later, the ambulance arrived. The doctor confirmed that there was nothing more that could be done.
Mr. Snitcofsky went home. Nobody had asked for his name or address or phone number. … And it wasn’t because they already knew who he was. In fact, there wasn’t any sort of relationship there. Mr. Snitcofsky had only known his neighbors by sight. His actions that day, however, “did not come without a cost. It took me weeks – months, actually – to put myself together again,” he said. The things he saw, the things he heard, everything about that night played over and over in his head. “I had trouble sleeping. I would play out different scenarios in my head. I questioned myself. I second-guessed myself, criticized myself. It’s like some taboo subject. There’s no one to share the experience with, no one who gets it. But with time, I was able to process the event.
“For 2 months, I talked to my psychologist about it all,” he continued. “That really helped me a lot. In addition to therapy, I reached out to a couple I know – they’re both physicians – and to a firefighter who teaches CPR. Their insight and guidance allowed me to get to a point where I was able to understand that what I did was a good thing and that what I did was all that could have been done. But anyone who finds themselves in the position of having to do CPR – they’re going to be affected in many, many ways. It goes beyond the euphoria of seeing a person come back to life. Of that, I’m quite certain.”
We’ve all seen campaigns encouraging people to learn CPR and to be prepared if the need arises. But in training the public (and even health care professionals), not much, if anything, is said about the “collateral damage”: the psychological and emotional consequences of carrying out the procedure. These especially come into play when you don’t know whether the person survived, when your efforts weren’t able to reverse the sudden cardiac arrest, or when the person you gave CPR to was a loved one – a case that may entail immediate therapeutic interventions to minimize or prevent the risk of suffering long-lasting trauma.
In May 2020, popular American activist and educator Kristin Flanary saw someone suffering cardiac arrest. She stepped in and started doing CPR. And she continued doing CPR … for 10 long minutes. The person she was trying to save was her 34-year-old husband, ophthalmologist and comedian Will Flanary. On Twitter, where she’s known as Lady Glaucomflecken, Ms. Flanary recently shared the following message, putting the topic of CPR and automated external defibrillator training front and center.
“Yes, everyone should learn #CPRandAED. But if we are going to ask people to perform such a brutal task, it’s imperative that we also provide them with the info and resources they need to process it mentally and emotionally. It’s traumatic and life changing. It’s irresponsible and unethical to ask people to help in such a brutal and traumatic way and then neglect to help them in return.” In less than a month, the tweet has racked up over 200,000 views.
Doing one’s duty
There are many people who work to promote CPR and strengthen the other links in the chain of survival for out-of-hospital sudden cardiac arrest, such as prompt access to and delivery of early defibrillation. According to them, any negative psychological impact of intervening is temporary and, when compared with the satisfaction of having done one’s duty, quite insignificant – even if the efforts to save a person’s life are not successful.
“In 99.9% of cases, people who have performed CPR feel a sense of satisfaction, even happiness, knowing that they’ve helped. The individuals I’ve spoken with, I’ve never heard any of them say that they felt worse after the event or that they needed to see a psychologist,” said Mario Fitz Maurice, MD, director of the Arrhythmia Council of the Argentine Society of Cardiology and head of Electrophysiology at Rivadavia Hospital in Buenos Aires. He went on to tell this news organization, “Of course, some degree of fear, sadness, or melancholy can remain afterward. But it seems to me, and there are reports saying as much, that, in the end, what stands out in the person’s mind is the fact that they tried to save a life. And for them, there’s joy in knowing this.”
Dr. Fitz Maurice, who is also the director of the National Arrhythmia Institute in Buenos Aires, pointed out that the kind of person who takes CPR classes “has a profile that’s going to allow them to be psychologically involved; they’re the caring person, the one who’s ready and willing to help people.” And he added that, at his hospital, if they can identify the individuals or first responders who have done CPR on a patient, the protocol is to always contact them to offer psychological care and assistance. “But in 99% of cases, they don’t even understand why we’re calling them, they’re extremely happy to have taken part.”
Some studies, though, paint a much different picture, one that shows that providing CPR can be emotionally challenging and have consequences in terms of one’s family and work life. A qualitative study published in 2016 looked into the experiences of 20 lay rescuers in Norway – five were health educated – who had provided CPR to 18 out-of-hospital cardiac arrest (OHCA) victims, 66% of whom survived. The time from experiencing the OHCA incident to participating in the interview ranged from 6 days to 13 years (median 5.5 years). Several participants reported the OHCA incident as a “shocking and terrifying” experience. Tiredness, exhaustion, confusion, and feeling alone about the OHCA experience were individual reactions that could vary in time from days to months. Anxiety and insomnia were also experienced following the incident.
Some lay rescuers described the influence on work and family life, and a few of them described deep sorrow, even several years after the incident. Overall, they reported repetitive self-criticism regarding whether they could have carried out anything else to achieve a better outcome for the cardiac arrest victim. All of them wanted to be informed about the outcome. And four of the lay rescuers needed professional counseling to process the OHCA experience.
In 2020, another qualitative study was conducted, this time in Taiwan. There were nine participants, none of whom were health professionals. Each had provided initial CPR and defibrillation with AED in public locations. Event-to-interview duration was within 1 year and 1-2 years. The major findings from the study were the following:
- The lay rescuers possessed helping traits and high motivation.
- The lay rescuers reported certain aspects of rescue reality that differed much from prior training and expectations, including difficulty in the depth of chest compression, and uncertainties in real emergency situations.
- The lay rescuers gained positive personal fulfillment in sharing their experience and receiving positive feedback from others, and were willing to help next time, although they experienced a short-term negative psychological impact from the event. “Measures should be taken to increase [a] layperson’s confidence and situation awareness, to reduce training-reality discrepancy, and to build up a support system to avoid negative psychological effects.” This was the conclusion of the study team, which was led by Matthew Huei-Ming Ma, MD, PhD. A professor in the department of emergency medicine at National Taiwan University in Taipei, he is also on the board of directors of the Resuscitation Council of Asia.
Potential trauma
In recalling his experience, Mr. Snitcofsky said, “The hardest part of it all was the moment that I stopped giving CPR, that moment of letting go. This became the image that kept coming back to me, the traumatic moment I hadn’t thought about.”
Psychiatrist Daniel Mosca, MD, is the founder and former president of the Argentine Society of Trauma Psychology. He is also the coordinator of the human factors team at the City of Buenos Aires Emergency Medical Care System. “Any event has the potential to be traumatic, all the more so when it’s an event where you come face to face with death and uncertainty. But how a rescuer reacts will depend on their psychological makeup.” Of the individuals who were held for months or years in the jungle as hostages of the Revolutionary Armed Forces of Colombia, “only” half developed symptoms of posttraumatic stress disorder.
Dr. Mosca believes that a comment by Frank Ochberg, MD, speaks to this finding. “In many cases, peritraumatic symptoms are a normal person’s normal response to an abnormal situation.” For a lot of people who have found themselves having to perform CPR, the symptoms associated with the initial acute stress reaction will resolve on their own in 30-90 days. “But if this doesn’t happen, and those symptoms persist, psychotherapeutic or pharmacological intervention will be necessary,” he noted.
“In CPR classes, it would be good for the instructors to talk about the warning signs that people should look out for in themselves and their fellow rescuers. So, for example, insomnia, anxiety, a heightened state of alertness, feeling disconnected from reality,” Dr. Mosca told this news organization.
“Another thing that can help rescuers is letting them know what happened to the person they gave CPR to. This way, they can get closure,” suggested Manlio Márquez Murillo, MD, a cardiologist and electrophysiologist in Mexico. He is also the coordinator of the Alliance Against Sudden Cardiac Death at the Interamerican Society of Cardiology.
“Medical and nursing societies would have to develop a brief protocol or performance standard. The goal would be to ensure that rescuers are asked for their contact information and that someone gets in touch to debrief them and to offer them care. Next would come the treatment part, to resolve any remaining aftereffects,” said in an interview.
For example, a three-stage Lay Responder Support Model (LRSM) was developed and implemented as part of a lay responder support program established in 2014 by the Peel Regional Council in Ontario. The LRSM identifies and engages individuals who witnessed or participated directly or indirectly in an OHCA, inviting them to participate in a debriefing session facilitated by a trained practitioner. Held 24-48 hours post event, the debriefing allows lay responders to contextualize their reaction to the event. The conversation also serves as an opportunity for them to fully articulate their concerns, questions, and thoughts. The facilitator can communicate stress reduction techniques and address psychological first aid needs as they emerge. Approximately 1 week post event, a secondary follow-up occurs. If the lay responder communicates a continuing struggle with symptoms impacting and interfering with everyday life, the facilitator offers a coordinated or facilitated referral for mental health support.
In an article published in the Journal of Cardiac Failure. Ms. Flanary speaks about the three kinds of language that anyone who was either forced to or inspired to perform CPR can use to help process their trauma: words that explain what happened, words that name (eg, “forgotten patients”), and words that validate the experience and allow the person to articulate their feelings. The tools and technologies that organizations and health care professionals provide can help the healing process. Empathy and compassion, too, have a place.
But there are virtually no standardized and proactive initiatives of this kind in much of the world, including Latin America. So, most people who just happened to be in the right place at the right time find that they have to navigate the “after” part all on their own.
Other obstacles
Dr. Márquez Murillo finds it unfortunate that countries in the region have yet to enact “Good Samaritan” laws. If individuals render aid to someone suffering cardiac arrest, then these laws would ensure that they will not be held liable in any way. This is the case in Argentina and Uruguay. So, the fear of things turning into a legal matter may be holding people back from taking action; that fear could also create additional stress for those who end up stepping in to help.
Even with the legal safeguards, exceptional circumstances may arise where rescuers find themselves facing unexpected emotional challenges. In Argentina, Virginia Pérez Antonelli, the 17-year-old who tried in vain to save the life of Fernando Báez Sosa, had to testify at the trial of the eight defendants accused of brutally beating him in January 2020. The press, the public – the attention of an entire country – was focused on her. She had to respond to the defense attorneys who were able to ask whether she was sure that she performed the CPR maneuvers correctly. And a few weeks ago, a medical examiner hired by the defense suggested that “the CPR may have made the situation worse” for the victim. An indignant Dr. Fitz Maurice responded on Twitter: “CPR SAVES LIVES!! Let’s not let a CHEAP AND BASELESS argument destroy all the work that’s been done…!”
Of course, there are consequences that are beyond our control and others that can, in fact, be anticipated and planned for. Dr. Fitz Maurice brought up a preventive approach: Make CPR second nature, teach it in schools, help people overcome their fears. “Cardiac deaths are 200 times more frequent than deaths resulting from fires – and we practice fire drills a lot more than we practice CPR,” he told this news organization. In a society where there is widespread training on the procedure, where people regularly practice the technique, those who have had the experience of giving someone CPR will feel less alone, will be better understood by others.
“On the other hand, beyond the initial impact and the lack of a formal support system, the medium- and long-term outcome for those who acted is also psychologically and emotionally favorable,” said Jorge Bombau, MD, an obstetrician/gynecologist in Buenos Aires. After Dr. Bombau’s 14-year-old son Beltrán suddenly died during a school sports tournament, Dr. Bombau became a prominent advocate spreading the word about CPR.
“I don’t know anyone who regrets doing CPR,” he told this news organization. “There may be a brief period when the person feels distressed or depressed, when they have trouble sleeping. But it’s been proven that doing a good deed improves one’s mood. And what better deed is there than trying to save someone’s life? Whether their efforts were successful or in vain, that person has, at the end of the day, done something meaningful and worthwhile.”
Mr. Snitcofsky shares this sentiment. For several months now, he’s been feeling he’s “in a good place.” And he’s been actively promoting CPR on social media. As he recently posted on Twitter, “I’m here to retweet everything that has to do with getting us all to become familiar with how to do CPR and working up the courage to do it. The training takes no more than a few hours.
“I want to know that, if I ever have an out-of-hospital sudden cardiac arrest, there will be neighbors, friends, or family members around who know how to do CPR. Every person who knows how to do CPR can persuade others, and those of us who’ve had to do CPR in real life are even better candidates for persuading others. And if one day a person ends up needing CPR, I want to step in again and make up for lost time. Here’s hoping it’ll do the job,” he concluded.
It’s the same for Matías Alonso, a journalist in Buenos Aires. On New Year’s Eve 15 years ago, he was at a family dinner when, a few minutes before midnight, he found himself giving CPR to his stepmother’s father. “Unfortunately, he passed away, but I continued doing CPR on him until the ambulance arrived. For some time, I felt a little guilty for not taking charge of the situation from the beginning, and because I had this idea in my head that more people pulled through and recovered. But afterwards, they really thanked me a lot. And that helped me realize that I’d done something. I didn’t stand still when faced with the inevitability of death. I understood that it was good to have tried,” Mr. Alonso told this news organization. “And next time … hopefully there won’t be a next time … but I’m more prepared, and I now know how I can do better.”
Mr. Alonso, Mr. Snitcofsky, Dr. Fitz Maurice, Dr. Mosca, Dr. Bombau, and Dr. Márquez Murillo disclosed no relevant financial relationships.

He is also the coordinator of the Alliance Against Sudden Cardiac Death at the Interamerican Society of Cardiology.
“Medical and nursing societies would have to develop a brief protocol or performance standard. The goal would be to ensure that rescuers are asked for their contact information and that someone gets in touch to debrief them and to offer them care. Next would come the treatment part, to resolve any remaining aftereffects,” said in an interview.
For example, a three-stage Lay Responder Support Model (LRSM) was developed and implemented as part of a lay responder support program established in 2014 by the Peel Regional Council in Ontario. The LRSM identifies and engages individuals who witnessed or participated directly or indirectly in an OHCA, inviting them to participate in a debriefing session facilitated by a trained practitioner. Held 24-48 hours post event, the debriefing allows lay responders to contextualize their reaction to the event. The conversation also serves as an opportunity for them to fully articulate their concerns, questions, and thoughts. The facilitator can communicate stress reduction techniques and address psychological first aid needs as they emerge. Approximately 1 week post event, a secondary follow-up occurs. If the lay responder communicates a continuing struggle with symptoms impacting and interfering with everyday life, the facilitator offers a coordinated or facilitated referral for mental health support.
In an article published in the Journal of Cardiac Failure. Ms. Flanary speaks about the three kinds of language that anyone who was either forced to or inspired to perform CPR can use to help process their trauma: words that explain what happened, words that name (eg, “forgotten patients”), and words that validate the experience and allow the person to articulate their feelings. The tools and technologies that organizations and health care professionals provide can help the healing process. Empathy and compassion, too, have a place.
But there are virtually no standardized and proactive initiatives of this kind in much of the world, including Latin America. So, most people who just happened to be in the right place at the right time find that they have to navigate the “after” part all on their own.
Other obstacles
Dr. Márquez Murillo finds it unfortunate that countries in the region have yet to enact “Good Samaritan” laws. If individuals render aid to someone suffering cardiac arrest, then these laws would ensure that they will not be held liable in any way. This is the case in Argentina and Uruguay. So, the fear of things turning into a legal matter may be holding people back from taking action; that fear could also create additional stress for those who end up stepping in to help.
Even with the legal safeguards, exceptional circumstances may arise where rescuers find themselves facing unexpected emotional challenges. In Argentina, Virginia Pérez Antonelli, the 17-year-old who tried in vain to save the life of Fernando Báez Sosa, had to testify at the trial of the eight defendants accused of brutally beating him in January 2020. The press, the public – the attention of an entire country – was focused on her. She had to respond to the defense attorneys who were able to ask whether she was sure that she performed the CPR maneuvers correctly. And a few weeks ago, a medical examiner hired by the defense suggested that “the CPR may have made the situation worse” for the victim. An indignant Dr. Fitz Maurice responded on Twitter: “CPR SAVES LIVES!! Let’s not let a CHEAP AND BASELESS argument destroy all the work that’s been done…!”
Of course, there are consequences that are beyond our control and others that can, in fact, be anticipated and planned for. Dr. Fitz Maurice brought up a preventive approach: Make CPR second nature, teach it in schools, help people overcome their fears. “Cardiac deaths are 200 times more frequent than deaths resulting from fires – and we practice fire drills a lot more than we practice CPR,” he told this news organization. In a society where there is widespread training on the procedure, where people regularly practice the technique, those who have had the experience of giving someone CPR will feel less alone, will be better understood by others.
“On the other hand, beyond the initial impact and the lack of a formal support system, the medium- and long-term outcome for those who acted is also psychologically and emotionally favorable,” said Jorge Bombau, MD, an obstetrician/gynecologist in Buenos Aires. After Dr. Bombau’s 14-year-old son Beltrán suddenly died during a school sports tournament, Dr. Bombau became a prominent advocate spreading the word about CPR.
“I don’t know anyone who regrets doing CPR,” he told this news organization. “There may be a brief period when the person feels distressed or depressed, when they have trouble sleeping. But it’s been proven that doing a good deed improves one’s mood. And what better deed is there than trying to save someone’s life? Whether their efforts were successful or in vain, that person has, at the end of the day, done something meaningful and worthwhile.”
Mr. Snitcofsky shares this sentiment. For several months now, he’s been feeling he’s “in a good place.” And he’s been actively promoting CPR on social media. As he recently posted on Twitter, “I’m here to retweet everything that has to do with getting us all to become familiar with how to do CPR and working up the courage to do it. The training takes no more than a few hours.
“I want to know that, if I ever have an out-of-hospital sudden cardiac arrest, there will be neighbors, friends, or family members around who know how to do CPR. Every person who knows how to do CPR can persuade others, and those of us who’ve had to do CPR in real life are even better candidates for persuading others. And if one day a person ends up needing CPR, I want to step in again and make up for lost time. Here’s hoping it’ll do the job,” he concluded.
It’s the same for Matías Alonso, a journalist in Buenos Aires. On New Year’s Eve 15 years ago, he was at a family dinner when, a few minutes before midnight, he found himself giving CPR to his stepmother’s father. “Unfortunately, he passed away, but I continued doing CPR on him until the ambulance arrived. For some time, I felt a little guilty for not taking charge of the situation from the beginning, and because I had this idea in my head that more people pulled through and recovered. But afterwards, they really thanked me a lot. And that helped me realize that I’d done something. I didn’t stand still when faced with the inevitability of death. I understood that it was good to have tried,” Mr. Alonso told this news organization. “And next time … hopefully there won’t be a next time … but I’m more prepared, and I now know how I can do better.”
Mr. Alonso, Mr. Snitcofsky, Dr. Fitz Maurice, Dr. Mosca, Dr. Bombau, and Dr. Márquez Murillo disclosed no relevant financial relationships.

One year ago, as the sun was setting on a late fall day, Andrés Snitcofsky, a 40-year-old designer from Buenos Aires, Argentina, heard harrowing cries for help. It was the niece and the wife of one of his neighbors: a man in his 60s who the women had found “passed out” in the bedroom. “I did CPR for 5 minutes straight until a friend of the victim came in and asked me to stop, telling me that the man had probably been dead for 2 or 3 hours already. But I had no idea because I’d never seen a dead body before,” Mr. Snitcofsky told this news organization. A few minutes later, the ambulance arrived. The doctor confirmed that there was nothing more that could be done.
Mr. Snitcofsky went home. Nobody had asked for his name or address or phone number. … And it wasn’t because they already knew who he was. In fact, there wasn’t any sort of relationship there. Mr. Snitcofsky had only known his neighbors by sight. His actions that day, however, “did not come without a cost. It took me weeks – months, actually – to put myself together again,” he said. The things he saw, the things he heard, everything about that night played over and over in his head. “I had trouble sleeping. I would play out different scenarios in my head. I questioned myself. I second-guessed myself, criticized myself. It’s like some taboo subject. There’s no one to share the experience with, no one who gets it. But with time, I was able to process the event.
“For 2 months, I talked to my psychologist about it all,” he continued. “That really helped me a lot. In addition to therapy, I reached out to a couple I know – they’re both physicians – and to a firefighter who teaches CPR. Their insight and guidance allowed me to get to a point where I was able to understand that what I did was a good thing and that what I did was all that could have been done. But anyone who finds themselves in the position of having to do CPR – they’re going to be affected in many, many ways. It goes beyond the euphoria of seeing a person come back to life. Of that, I’m quite certain.”
We’ve all seen campaigns encouraging people to learn CPR and to be prepared if the need arises. But in training the public (and even health care professionals), not much, if anything, is said about the “collateral damage”: the psychological and emotional consequences of carrying out the procedure. These especially come into play when you don’t know whether the person survived, when your efforts weren’t able to reverse the sudden cardiac arrest, or when the person you gave CPR to was a loved one – a case that may entail immediate therapeutic interventions to minimize or prevent the risk of suffering long-lasting trauma.
In May 2020, popular American activist and educator Kristin Flanary saw someone suffering cardiac arrest. She stepped in and started doing CPR. And she continued doing CPR … for 10 long minutes. The person she was trying to save was her 34-year-old husband, ophthalmologist and comedian Will Flanary. On Twitter, where she’s known as Lady Glaucomflecken, Ms. Flanary recently shared the following message, putting the topic of CPR and automated external defibrillator training front and center.
“Yes, everyone should learn #CPRandAED. But if we are going to ask people to perform such a brutal task, it’s imperative that we also provide them with the info and resources they need to process it mentally and emotionally. It’s traumatic and life changing. It’s irresponsible and unethical to ask people to help in such a brutal and traumatic way and then neglect to help them in return.” In less than a month, the tweet has racked up over 200,000 views.
Doing one’s duty
There are many people who work to promote CPR and strengthen the other links in the chain of survival for out-of-hospital sudden cardiac arrest, such as prompt access to and delivery of early defibrillation. According to them, any negative psychological impact of intervening is temporary and, when compared with the satisfaction of having done one’s duty, quite insignificant – even if the efforts to save a person’s life are not successful.
“In 99.9% of cases, people who have performed CPR feel a sense of satisfaction, even happiness, knowing that they’ve helped. The individuals I’ve spoken with, I’ve never heard any of them say that they felt worse after the event or that they needed to see a psychologist,” said Mario Fitz Maurice, MD, director of the Arrhythmia Council of the Argentine Society of Cardiology and head of Electrophysiology at Rivadavia Hospital in Buenos Aires. He went on to tell this news organization, “Of course, some degree of fear, sadness, or melancholy can remain afterward. But it seems to me, and there are reports saying as much, that, in the end, what stands out in the person’s mind is the fact that they tried to save a life. And for them, there’s joy in knowing this.”
Dr. Fitz Maurice, who is also the director of the National Arrhythmia Institute in Buenos Aires, pointed out that the kind of person who takes CPR classes “has a profile that’s going to allow them to be psychologically involved; they’re the caring person, the one who’s ready and willing to help people.” And he added that, at his hospital, if they can identify the individuals or first responders who have done CPR on a patient, the protocol is to always contact them to offer psychological care and assistance. “But in 99% of cases, they don’t even understand why we’re calling them, they’re extremely happy to have taken part.”
Some studies, though, paint a much different picture, one that shows that providing CPR can be emotionally challenging and have consequences in terms of one’s family and work life. A qualitative study published in 2016 looked into the experiences of 20 lay rescuers in Norway – five were health educated – who had provided CPR to 18 out-of-hospital cardiac arrest (OHCA) victims, 66% of whom survived. The time from experiencing the OHCA incident to participating in the interview ranged from 6 days to 13 years (median 5.5 years). Several participants reported the OHCA incident as a “shocking and terrifying” experience. Tiredness, exhaustion, confusion, and feeling alone about the OHCA experience were individual reactions that could vary in time from days to months. Anxiety and insomnia were also experienced following the incident.
Some lay rescuers described the influence on work and family life, and a few of them described deep sorrow, even several years after the incident. Overall, they reported repetitive self-criticism regarding whether they could have carried out anything else to achieve a better outcome for the cardiac arrest victim. All of them wanted to be informed about the outcome. And four of the lay rescuers needed professional counseling to process the OHCA experience.
In 2020, another qualitative study was conducted, this time in Taiwan. There were nine participants, none of whom were health professionals. Each had provided initial CPR and defibrillation with AED in public locations. Event-to-interview duration was within 1 year and 1-2 years. The major findings from the study were the following:
- The lay rescuers possessed helping traits and high motivation.
- The lay rescuers reported certain aspects of rescue reality that differed much from prior training and expectations, including difficulty in the depth of chest compression, and uncertainties in real emergency situations.
- The lay rescuers gained positive personal fulfillment in sharing their experience and receiving positive feedback from others, and were willing to help next time, although they experienced a short-term negative psychological impact from the event. “Measures should be taken to increase [a] layperson’s confidence and situation awareness, to reduce training-reality discrepancy, and to build up a support system to avoid negative psychological effects.” This was the conclusion of the study team, which was led by Matthew Huei-Ming Ma, MD, PhD. A professor in the department of emergency medicine at National Taiwan University in Taipei, he is also on the board of directors of the Resuscitation Council of Asia.
Potential trauma
In recalling his experience, Mr. Snitcofsky said, “The hardest part of it all was the moment that I stopped giving CPR, that moment of letting go. This became the image that kept coming back to me, the traumatic moment I hadn’t thought about.”
Psychiatrist Daniel Mosca, MD, is the founder and former president of the Argentine Society of Trauma Psychology. He is also the coordinator of the human factors team at the City of Buenos Aires Emergency Medical Care System. “Any event has the potential to be traumatic, all the more so when it’s an event where you come face to face with death and uncertainty. But how a rescuer reacts will depend on their psychological makeup.” Of the individuals who were held for months or years in the jungle as hostages of the Revolutionary Armed Forces of Colombia, “only” half developed symptoms of posttraumatic stress disorder.
Dr. Mosca believes that a comment by Frank Ochberg, MD, speaks to this finding. “In many cases, peritraumatic symptoms are a normal person’s normal response to an abnormal situation.” For a lot of people who have found themselves having to perform CPR, the symptoms associated with the initial acute stress reaction will resolve on their own in 30-90 days. “But if this doesn’t happen, and those symptoms persist, psychotherapeutic or pharmacological intervention will be necessary,” he noted.
“In CPR classes, it would be good for the instructors to talk about the warning signs that people should look out for in themselves and their fellow rescuers. So, for example, insomnia, anxiety, a heightened state of alertness, feeling disconnected from reality,” Dr. Mosca told this news organization.
“Another thing that can help rescuers is letting them know what happened to the person they gave CPR to. This way, they can get closure,” suggested Manlio Márquez Murillo, MD, a cardiologist and electrophysiologist in Mexico. He is also the coordinator of the Alliance Against Sudden Cardiac Death at the Interamerican Society of Cardiology.
“Medical and nursing societies would have to develop a brief protocol or performance standard.

A technicality could keep RSV shots from kids in need
which has put an estimated 90,000 U.S. infants and small children in the hospital since the start of October.
But only one of the shots is designed to be given to babies, and a glitch in congressional language may make it difficult to allow children from low-income families to get it as readily as the well insured.
Since 1994, routine vaccination has been a childhood entitlement under the Vaccines for Children program, through which the federal government buys millions of vaccines and provides them free through pediatricians and clinics to children who are uninsured, underinsured, or on Medicaid – more than half of all American kids.
The 1993 law creating the program didn’t specifically include antibody shots, which were used only as rare emergency therapy at the time the bill was written.
But the first medication of its kind likely to be available to babies, called nirsevimab (it was approved in Europe in December, and Food and Drug Administration approval is expected in the summer of 2023), is not a vaccine but rather a monoclonal antibody that neutralizes RSV in the bloodstream.
The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices is certain to recommend giving the antibody to infants, said Kelly Moore, MD, president of the advocacy group Immunize.org. The CDC is currently assessing whether nirsevimab would be eligible for the Vaccines for Children program, agency spokesperson Kristen Nordlund told KHN.
Failing to do so would “consign thousands upon thousands of infants to hospitalization and serious illness for semantic reasons despite existence of an immunization that functionally performs just like a seasonal vaccine,” Dr. Moore said.
Officials from Sanofi, which is producing the nirsevimab injection along with AstraZeneca, declined to state a price but said the range would be similar to that of a pediatric vaccine course. The CDC pays about $650 for the most expensive routine vaccine, the four shots against pneumococcal infection. In other words, FDA approval would make nirsevimab a blockbuster drug worth billions annually if it’s given to a large share of the 3.7 million or so children born in the U.S. each year.
Pfizer and GlaxoSmithKline are making traditional vaccines against RSV and expect FDA approval later in 2023. Pfizer’s shot initially would be given to pregnant women – to shield their babies from the disease – while GSK’s would be given to the elderly.
Vaccines designed for infants are in the pipeline, but some experts are still nervous about them. A 1966 RSV vaccine trial failed spectacularly, killing two toddlers, and immunologists aren’t totally in agreement over the cause, said Barney Graham, MD, PhD, the retired National Institutes of Health scientist whose studies of the episode contributed to successful COVID-19 and RSV vaccines.
After 2 years of COVID lockdowns and masking slowed its transmission, RSV exploded across the United States in 2023, swamping pediatric intensive care units.
Sanofi and AstraZeneca hope to have nirsevimab approved by the FDA, recommended by the CDC, and deployed nationwide by fall to prevent future RSV epidemics.
Their product is designed to be provided before a baby’s first winter RSV season. In clinical trials, the antibodies provided up to 5 months of protection. Most children wouldn’t need a second dose because the virus is not a mortal danger to healthy kids over a year old, said Jon Heinrichs, a senior member of Sanofi’s vaccines division.
If the antibody treatment is not accepted for the Vaccines for Children program, that will limit access to the shot for the uninsured and those on Medicaid, the majority of whom represent racial or ethnic minorities, Dr. Moore said. The drugmakers would have to negotiate with each state’s Medicaid program to get it on their formularies.
Excluding the shot from Vaccines for Children “would only worsen existing health disparities,” said Sean O’Leary, MD, a professor of pediatrics at the University of Colorado at Denver, Aurora, and chair of the infectious diseases committee of the American Academy of Pediatrics.
RSV affects babies of all social classes but tends to hit poor, crowded households hardest, said Dr. Graham. “Family history of asthma or allergy makes it worse,” he said, and premature babies are also at higher risk.
While 2%-3% of U.S. infants are hospitalized with RSV each year, only a few hundred don’t survive. But as many as 10,000 people 65 and older perish because of an infection every year, and a little-discussed legal change will make RSV and other vaccines more available to this group.
A section of the 2022 Inflation Reduction Act that went into effect Jan. 1 ends out-of-pocket payments for all vaccines by Medicare patients – including RSV vaccines, if they are licensed for this group.
Before, “if you hadn’t met your deductible, it could be very expensive,” said Leonard Friedland, MD, vice president for scientific affairs and public health in GSK’s vaccines division, which also makes shingles and combination tetanus-diphtheria-whooping cough boosters covered by the new law. “It’s a tremendously important advance.”
Of course, high levels of vaccine hesitancy are likely to blunt uptake of the shots regardless of who pays, said Jennifer Reich, a sociologist at the University of Colorado who studies vaccination attitudes.
New types of shots, like the Sanofi-AstraZeneca antibodies, often alarm parents, and Pfizer’s shot for pregnant women is likely to push fear buttons as well, she said.
Public health officials “don’t seem very savvy about how to get ahead” of claims that vaccines undermine fertility or otherwise harm people, said Ms. Reich.
On the other hand, this winter’s RSV epidemic will be persuasive to many parents, said Heidi Larson, leader of the Vaccine Confidence Project and a professor of anthropology at the London School of Hygiene and Tropical Medicine.
“It’s a scary thing to have your kid hospitalized with RSV,” she said.
While unfortunate, “the high number of children who died or were admitted to the ICU in the past season with RSV – in some ways that’s helpful,” said Laura Riley, MD, chair of obstetrics and gynecology at Weill Cornell Medicine, New York.
Specialists in her field haven’t really started talking about how to communicate with women about the vaccine, said Dr. Riley, who chairs the immunization group at the American College of Obstetricians and Gynecologists.
“Everyone’s been waiting to see if it gets approved,” she said. “The education has to start soon, but it’s hard to roll out education before you roll out the shot.”

New types of shots, like the Sanofi-AstraZeneca antibodies, often alarm parents, and Pfizer’s shot for pregnant women is likely to push fear buttons as well, she said.
Public health officials “don’t seem very savvy about how to get ahead” of claims that vaccines undermine fertility or otherwise harm people, said Ms. Reich.
On the other hand, this winter’s RSV epidemic will be persuasive to many parents, said Heidi Larson, leader of the Vaccine Confidence Project and a professor of anthropology at the London School of Hygiene and Tropical Medicine.
“It’s a scary thing to have your kid hospitalized with RSV,” she said.
While unfortunate, “the high number of children who died or were admitted to the ICU in the past season with RSV – in some ways that’s helpful,” said Laura Riley, MD, chair of obstetrics and gynecology at Weill Cornell Medicine, New York.
Specialists in her field haven’t really started talking about how to communicate with women about the vaccine, said Dr. Riley, who chairs the immunization group at the American College of Obstetricians and Gynecologists.
“Everyone’s been waiting to see if it gets approved,” she said. “The education has to start soon, but it’s hard to roll out education before you roll out the shot.”

which has put an estimated 90,000 U.S. infants and small children in the hospital since the start of October.
But only one of the shots is designed to be given to babies, and a glitch in congressional language may make it difficult to allow children from low-income families to get it as readily as the well insured.
Since 1994, routine vaccination has been a childhood entitlement under the Vaccines for Children program, through which the federal government buys millions of vaccines and provides them free through pediatricians and clinics to children who are uninsured, underinsured, or on Medicaid – more than half of all American kids.
The 1993 law creating the program didn’t specifically include antibody shots, which were used only as rare emergency therapy at the time the bill was written.
But the first medication of its kind likely to be available to babies, called nirsevimab (it was approved in Europe in December, and Food and Drug Administration approval is expected in the summer of 2023), is not a vaccine but rather a monoclonal antibody that neutralizes RSV in the bloodstream.
The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices is certain to recommend giving the antibody to infants, said Kelly Moore, MD, president of the advocacy group Immunize.org. The CDC is currently assessing whether nirsevimab would be eligible for the Vaccines for Children program, agency spokesperson Kristen Nordlund told KHN.
Failing to do so would “consign thousands upon thousands of infants to hospitalization and serious illness for semantic reasons despite existence of an immunization that functionally performs just like a seasonal vaccine,” Dr. Moore said.
Officials from Sanofi, which is producing the nirsevimab injection along with AstraZeneca, declined to state a price but said the range would be similar to that of a pediatric vaccine course. The CDC pays about $650 for the most expensive routine vaccine, the four shots against pneumococcal infection. In other words, FDA approval would make nirsevimab a blockbuster drug worth billions annually if it’s given to a large share of the 3.7 million or so children born in the U.S. each year.
Pfizer and GlaxoSmithKline are making traditional vaccines against RSV and expect FDA approval later in 2023. Pfizer’s shot initially would be given to pregnant women – to shield their babies from the disease – while GSK’s would be given to the elderly.
Vaccines designed for infants are in the pipeline, but some experts are still nervous about them. A 1966 RSV vaccine trial failed spectacularly, killing two toddlers, and immunologists aren’t totally in agreement over the cause, said Barney Graham, MD, PhD, the retired National Institutes of Health scientist whose studies of the episode contributed to successful COVID-19 and RSV vaccines.
After 2 years of COVID lockdowns and masking slowed its transmission, RSV exploded across the United States in 2023, swamping pediatric intensive care units.
Sanofi and AstraZeneca hope to have nirsevimab approved by the FDA, recommended by the CDC, and deployed nationwide by fall to prevent future RSV epidemics.
Their product is designed to be provided before a baby’s first winter RSV season. In clinical trials, the antibodies provided up to 5 months of protection. Most children wouldn’t need a second dose because the virus is not a mortal danger to healthy kids over a year old, said Jon Heinrichs, a senior member of Sanofi’s vaccines division.
If the antibody treatment is not accepted for the Vaccines for Children program, that will limit access to the shot for the uninsured and those on Medicaid, the majority of whom represent racial or ethnic minorities, Dr. Moore said. The drugmakers would have to negotiate with each state’s Medicaid program to get it on their formularies.
Excluding the shot from Vaccines for Children “would only worsen existing health disparities,” said Sean O’Leary, MD, a professor of pediatrics at the University of Colorado at Denver, Aurora, and chair of the infectious diseases committee of the American Academy of Pediatrics.
RSV affects babies of all social classes but tends to hit poor, crowded households hardest, said Dr. Graham. “Family history of asthma or allergy makes it worse,” he said, and premature babies are also at higher risk.
While 2%-3% of U.S. infants are hospitalized with RSV each year, only a few hundred don’t survive. But as many as 10,000 people 65 and older perish because of an infection every year, and a little-discussed legal change will make RSV and other vaccines more available to this group.
A section of the 2022 Inflation Reduction Act that went into effect Jan. 1 ends out-of-pocket payments for all vaccines by Medicare patients – including RSV vaccines, if they are licensed for this group.

Gene test may offer insights into treatment response in advanced NSCLC
therapy despite their poor status, researchers reported.
Positive findings on the test, known as DetermaIO, were “associated with efficacy of response to ICI therapy in advanced NSCLC patients,” Matthew G. Varga, PhD, manager of scientific affairs at Oncocyte, said in an interview. “These data suggest that DetermaIO warrants further study in poor performance status patients as it has the potential to identify likely responders to ICI therapy.”
Oncocyte, which is developing the test, presented the findings in a poster at the annual meeting of the Society for Immunotherapy of Cancer.
According to Dr. Varga, “DetermaIO is an RT-qPCR test that can be applied to FFPE [formalin-fixed, paraffin-embedded] tissue specimens to quantify the relative gene expression of 27 genes and subsequently applies our proprietary algorithm to generate an IO score based on the gene expression profile. The DetermaIO score is a binary IO+ or IO– score, representing likely responder or nonresponder, respectively.”
The test was originally developed for triple negative breast cancer, Dr. Varga said, and it’s been validated in non–small cell lung cancer, metastatic urothelial carcinoma, and metastatic colorectal carcinoma.
For the study, the researchers retrospectively tracked associations between DetermaIO score and either progression-free survival (PFS) or overall survival (OS) in 147 patients in Canada with NSCLC who were treated with ICI monotherapy. All had programmed death-ligand 1 (PD-L1) ≥ 50%.
Overall, outcomes were poor: The median survival was 12.7 months, and median PFS was 7.0 months. These outcomes were even worse in those who underwent therapy as a second- line treatment: The median survival was 9.7 months, and median PFS was 4.4 months.
“DetermaIO was significantly associated with PFS at hazard ratio [HR] = 0.55, 95% [confidence interval] CI, 0.32-0.94, P = .028. In our analyses, a hazard ratio less than 1 suggests lower risk – i.e, that DetermaIO+ patients have lower risk of an event – death or progression – compared to a DetermaIO– patient,” Dr. Varga said. “The association for overall survival was not statistically significant, but it was suggestive of clinically meaningful benefit.”
He added that “we could identify likely responders from nonresponders, suggesting that the DetermaIO score adds both independent and incremental data to the existing gold standard biomarker. The objective response rate for all first-line patients – n = 78 – was 44.9%. Twenty-two DetermaIO– tumors had a 23% response rate (5 partial responses) whereas of the 56 DetermaIO+ patients, the response rate was 54% (2 complete response and 28 partial responses).”
A score on the test, he said, was not associated with OS or PFS in patients who received second-line or later treatment.
The study was not designed to evaluate the predictive power of the test. “For a biomarker to be defined as predictive requires a formal test of interaction between a treatment group (ICI monotherapy, for example) vs. a control group (chemo-only or other regimen),” Dr. Varga explained. “In our analysis, there was no group of patients who did not receive ICI monotherapy. Thus a test for interaction and a predictive claim cannot be made.”
The test is available for at no cost via an early access program, Dr. Varga said, and Oncocyte is getting ready to seek Medicare coverage. The ultimate cost of the test, he said, is unknown.

Systemic sclerosis antibodies show link to interstitial lung disease in RA
Adults with rheumatoid arthritis or primary Sjogren’s syndrome plus interstitial lung disease had higher levels of systemic sclerosis–specific antibodies than those without lung disease, based on data from 101 individuals.
Systemic sclerosis (SSc) has been associated with the development of interstitial lung disease (ILD), but the prevalence of SSc autoantibodies in patients with rheumatoid arthritis (RA) and primary Sjogren’s syndrome (SS) has not been explored, wrote Vasilike Koulouri, MD, of Kapodistrian University of Athens, and colleagues.
In a study published in the Journal of Translational Autoimmunity, the researchers reviewed serum data from patients with RA and SS using immunoblot assays to determine the prevalence of SSc-specific and anti-Ro52 autoantibodies, both of which have been associated with ILD in SSc patients.
The study population included 28 RA patients with ILD, 32 RA patients without ILD, 9 primary SS patients with ILD, and 32 primary SS patients with no ILD. The mean age of the RA participants was 63.4 years, 70% were women, and the mean age at RA diagnosis was 50.2 years. The mean age of the primary SS group was 60.3 years, 87.8% were female, and the mean age at diagnosis was 52.7 years.
Overall, SSc-specific antibodies across all titers were detected more frequently in RA patients with ILD compared with those with no ILD, though not statistically significant (42.9% vs. 21.9%, P = .08). However, “This trend was mainly attributed to the statistically significant difference between the two groups at strong titers (25% vs. 3.1%, P = .01),” the researchers wrote. Notably, they added.
No significant differences appeared in the prevalence of SSc-specific or Ro52 autoantibodies between primary SS patients with and without ILD, which might be attributable in part to the increased prevalence of anticentromere antibodies in primary SS, the researchers said.
RA patients who were positive for SSc-specific antibodies at strong titers were significantly more likely to have respiratory abnormalities than those who were negative (87.5% vs. 47.2%, P = .04), but no such differences appeared in primary SS patients.
“Early detection of SSc antibodies could be important in clinical practice as it may mandate further diagnostic (for example, screening for pulmonary hypertension) and therapeutic approaches of these patients,” the researchers wrote in their discussion.
The study findings were limited by several factors, mainly the small sample size, but also the potential for false-positive results on antibody titers, lack of data on the clinical significance of medium autoantibody titers, and the lack of long-term follow-up data, the researchers noted.
However, the results suggest that many seropositive RA patients with evidence of ILD “may evolve to a clinically evident overlap of RA and SSc” that would benefit from targeted treatment, they concluded.
The study was supported by a grant from Novartis AG and by the Molecular Immunology and Clinical Applications Unit, Department of Physiology, School of Medicine, National and Kapodistrian University of Athens. The researchers had no financial conflicts to disclose.

The challenge of incidentally detected interstitial lung abnormalities
Clinicians working within the U.S. health care system order CTs; it’s just what we do, and we do it a lot. This isn’t necessarily bad, but an inevitable byproduct is the pandemic of incidental findings. One underrecognized but frequent “incidentaloma” on CT is an interstitial lung abnormality (ILA). The Fleischner Society defines an ILA as honeycombing, traction bronchiectasis, parenchymal distortions, and reticular abnormalities that take up more than 5% of a particular lung zone in a patient without a clinical diagnosis of interstitial lung disease (ILD). In essence, ILAs are both a radiographic and a clinical diagnosis.
ILAs are common. With the advent of lung cancer screening and advances in CT technology, we’re now inundated with detailed images of lung parenchyma in older smokers who are at high risk for respiratory disease. The resulting opportunity for early identification of disease is as exciting as the risk for overdiagnosis, excessive testing, and unnecessary treatment is frightening. Early diagnosis remains critical for preventing irreversible respiratory disease. But as with any disease process, when we attempt to detect pathology before it has become apparent, the line between benign change and true abnormality is blurred.
Such is the challenge with ILAs. Past studies have shown an association between ILAs and morbidity and mortality, but considerable uncertainty persists over what the ILAs represent and how they should be managed. A recent study published in the American Journal of Respiratory and Critical Care Medicine provides some clarity. The authors used data from the COPDGene cohort to correlate ILAs with lung testing, and functional and respiratory outcomes. As with other studies, they found that approximately 10% of the COPDGene patients that they examined had ILAs on CT and half of those met their criteria for “suspected ILD.” Suspected ILD was defined radiographically (definite fibrosis) and on lung function testing (abnormal forced vital capacity [FVC] or diffusing capacity of the lungs for carbon monoxide [DLCO]). The patients with suspected ILD had worse clinical outcomes; being a Black individual, pack-years of smoking, and GOLD stage on spirometry were independently associated with suspected ILD.
This type of study is urgently needed. Given their high prevalence, we’re in dire need of a valid model for risk stratifying ILAs. The authors of this study have moved us closer, but we’ve still got a long way to go. The study has significant limitations. First, although patients with previous documentation of ILD were excluded from COPDGene, no formal, multidisciplinary assessment was performed; therefore, some of the patients labeled as having ILA probably had diagnosable ILD. Their possible inclusion would falsely increase the prevalence of clinically important ILAs and exaggerate the relationship between ILAs and clinical outcomes.
The rhetorical gymnastics performed throughout the paper are necessary yet problematic. “Suspected ILD” is not a recognized diagnosis and the definition is therefore arbitrary. To the extent that “suspected ILD” requires an abnormality on spirometry or DLCO, one could argue it’s the lung function changes and not the radiographic findings that are driving the differences. In fact, “suspected ILD” was defined by lung function more often than radiographic criteria (16% had definite fibrosis on CT, 57% had an abnormal FVC, and 67% had an abnormal DLCO). Patients with ILAs without suspected ILD had outcomes that weren’t statistically different from those with no ILAs at all, implying that the lung testing and not the ILA is the better discriminator. Regardless, this leads us back to where we started before this paper was published: ILAs require lung function testing and referral to a pulmonologist for proper risk stratification. An accompanying editorial highlights these and other limitations.
One particular problem that isn’t addressed by the authors or the editorial is their findings on race. The authors concluded that Black persons with ILAs are more likely to have “suspected ILD.” However, their definition suffers from an insidious form of incorporation bias generated by the way they handled their DLCO reference values. The Global Lung Function Initiative equations they used were derived exclusively from White persons. In accordance with the recent American Thoracic Society/European Respiratory Society (ATS/ERS) statement on lung testing, the authors did not apply a fixed correction factor to adjust for race. Without such an adjustment, Black persons would be biased toward having lower percent predicted values for DLCO. In short, self-identified Black individuals would be more likely to have a predicted DLCO of less than 70% and to therefore meet criteria for “suspected ILD.” The resulting effects on biologic plausibility, causal inference, and the strength of the relationship between “suspected ILD” and clinical outcomes will vary by whether the association between race and lung function is considered a product of inherent biologic variability or a result of external (socioeconomic and environmental) effects.
In summary, ILAs remain a challenge for radiologists, primary care providers, pulmonologists, and anyone else who orders a CT of the lungs. Despite its limitations, I believe the recently published paper pushes us forward conceptually. Perhaps its most important contribution is showing that 50% of ILAs are clinically insignificant by definition. This offers further reassurance that a subset of ILAs can be dismissed. Now, all we need is an easy, cost-effective, and efficient way to identify this subset.

With the advent of lung cancer screening and advances in CT technology, we’re now inundated with detailed images of lung parenchyma in older smokers who are at high risk for respiratory disease. The resulting opportunity for early identification of disease is as exciting as the risk for overdiagnosis, excessive testing, and unnecessary treatment is frightening. Early diagnosis remains critical for preventing irreversible respiratory disease. But as with any disease process, when we attempt to detect pathology before it has become apparent, the line between benign change and true abnormality is blurred.
Such is the challenge with ILAs. Past studies have shown an association between ILAs and morbidity and mortality, but considerable uncertainty persists over what the ILAs represent and how they should be managed. A recent study published in the American Journal of Respiratory and Critical Care Medicine provides some clarity. The authors used data from the COPDGene cohort to correlate ILAs with lung testing, and functional and respiratory outcomes. As with other studies, they found that approximately 10% of the COPDGene patients that they examined had ILAs on CT and half of those met their criteria for “suspected ILD.” Suspected ILD was defined radiographically (definite fibrosis) and on lung function testing (abnormal forced vital capacity [FVC] or diffusing capacity of the lungs for carbon monoxide [DLCO]). The patients with suspected ILD had worse clinical outcomes; being a Black individual, pack-years of smoking, and GOLD stage on spirometry were independently associated with suspected ILD.
This type of study is urgently needed. Given their high prevalence, we’re in dire need of a valid model for risk stratifying ILAs. The authors of this study have moved us closer, but we’ve still got a long way to go. The study has significant limitations. First, although patients with previous documentation of ILD were excluded from COPDGene, no formal, multidisciplinary assessment was performed; therefore, some of the patients labeled as having ILA probably had diagnosable ILD. Their possible inclusion would falsely increase the prevalence of clinically important ILAs and exaggerate the relationship between ILAs and clinical outcomes.
The rhetorical gymnastics performed throughout the paper are necessary yet problematic. “Suspected ILD” is not a recognized diagnosis and the definition is therefore arbitrary. To the extent that “suspected ILD” requires an abnormality on spirometry or DLCO, one could argue it’s the lung function changes and not the radiographic findings that are driving the differences. In fact, “suspected ILD” was defined by lung function more often than radiographic criteria (16% had definite fibrosis on CT, 57% had an abnormal FVC, and 67% had an abnormal DLCO). Patients with ILAs without suspected ILD had outcomes that weren’t statistically different from those with no ILAs at all, implying that the lung testing and not the ILA is the better discriminator. Regardless, this leads us back to where we started before this paper was published: ILAs require lung function testing and referral to a pulmonologist for proper risk stratification. An accompanying editorial highlights these and other limitations.
One particular problem that isn’t addressed by the authors or the editorial is their findings on race. The authors concluded that Black persons with ILAs are more likely to have “suspected ILD.” However, their definition suffers from an insidious form of incorporation bias generated by the way they handled their DLCO reference values. The Global Lung Function Initiative equations they used were derived exclusively from White persons. In accordance with the recent American Thoracic Society/European Respiratory Society (ATS/ERS) statement on lung testing, the authors did not apply a fixed correction factor to adjust for race. Without such an adjustment, Black persons would be biased toward having lower percent predicted values for DLCO. In short, self-identified Black individuals would be more likely to have a predicted DLCO of less than 70% and to therefore meet criteria for “suspected ILD.” The resulting effects on biologic plausibility, causal inference, and the strength of the relationship between “suspected ILD” and clinical outcomes will vary by whether the association between race and lung function is considered a product of inherent biologic variability or a result of external (socioeconomic and environmental) effects.
In summary, ILAs remain a challenge for radiologists, primary care providers, pulmonologists, and anyone else who orders a CT of the lungs. Despite its limitations, I believe the recently published paper pushes us forward conceptually. Perhaps its most important contribution is showing that 50% of ILAs are clinically insignificant by definition. This offers further reassurance that a subset of ILAs can be dismissed. Now, all we need is an easy, cost-effective, and efficient way to identify this subset.

Clinicians working within the U.S. health care system order CTs; it’s just what we do, and we do it a lot. This isn’t necessarily bad, but an inevitable byproduct is the pandemic of incidental findings. One underrecognized but frequent “incidentaloma” on CT is an interstitial lung abnormality (ILA). The Fleischner Society defines an ILA as honeycombing, traction bronchiectasis, parenchymal distortions, and reticular abnormalities that take up more than 5% of a particular lung zone in a patient without a clinical diagnosis of interstitial lung disease (ILD). In essence, ILAs are both a radiographic and a clinical diagnosis.
