Rivaroxaban outmatched by VKAs for AFib in rheumatic heart disease
Contrary to expectations, vitamin K antagonists (VKAs) reduced the risk for ischemic stroke and death, compared with the factor Xa inhibitor rivaroxaban, (Xarelto, Janssen) in patients with rheumatic heart disease and atrial fibrillation (AFib), in the INVICTUS trial.
Patients receiving a VKA, typically warfarin, had a 25% lower risk for the primary outcome – a composite of stroke, systemic embolism, myocardial infarction, or death from vascular or unknown causes outcome – than receiving rivaroxaban (hazard ratio, 1.25; 95% confidence interval, 1.10-1.41).
This difference was driven primarily by a significant reduction in the risk for death in the VKA group, and without a significant increase in major bleeding, reported Ganesan Karthikeyan, MD, from the All India Institute of Medical Sciences in New Delhi.
“VKA should remain the standard of care for patients with rheumatic heart disease and atrial fibrillation,” he concluded in a hotline session at the annual congress of the European Society of Cardiology.
The study, simultaneously published in the New England Journal of Medicine, is the first randomized controlled trial to assess anticoagulant therapy in patients with rheumatic heart disease and AFib.
“Who could have possibly guessed these results? Certainly not me,” said invited discussant Renato D. Lopes, MD, MHS, PhD, Duke Clinical Research Institute, Durham, N.C. “To me, this is one more classical example of why we need to do randomized trials, since they are the only reliable way to determine treatment effects and drive clinical practice.”
Evidence gap
Rheumatic heart disease affects over 40 million people, mainly living in low- and low- to middle-income countries. About 20% of symptomatic patients have AF and an elevated stroke risk, but previous AFib trials excluded these patients, Dr. Karthikeyan noted.
INVICTUS was led by the Population Health Research Institute in Hamilton, Ont., and enrolled 4,565 patients from 24 countries in Africa, Asia, and Latin America who had rheumatic heart disease, AFib or atrial flutter, and an increased stroke risk caused by any of the following: CHA2DS2VASc score of 2 or more, moderate to severe mitral stenosis (valve area ≤ 2.0 cm2), left atrial spontaneous echo contrast, or left atrial thrombus.
Participants were randomly assigned to receive rivaroxaban, 20 mg once daily (15 mg/d if creatinine clearance was 15-49 mL/min), or a VKA titrated to an international normalized ratio (INR) of 2.0-3.0.
Warfarin was used in 79%-85% of patients assigned to VKA, with the percentage varying between visits. The INR was in therapeutic range in 33.2% of patients at baseline, 65.1% at 3 years, and 64.1% at 4 years.
During an average follow-up of 3.1 years, the primary outcome occurred in 446 patients in the VKA group (6.49% per year) and 560 patients in the rivaroxaban group (8.21% per year). The restricted mean survival time for the primary outcome was 1,675 vs. 1,599 days, respectively (difference, –76 days; 95% CI, –121 to –31 days; P for superiority < .001).
The rate of stroke or systemic embolism was similar between the VKA and rivaroxaban groups (75 vs. 94 events), although ischemic strokes were significantly lower with VKA (48 vs. 74 events).
No easy explanation
Deaths were significantly lower with VKA than rivaroxaban, at 442 versus 552 (restricted mean survival time for death, 1,608 vs. 1,587 days; difference, −72 days; 95% CI, –117 to –28 days).
“This reduction is not easily explained,” Dr. Karthikeyan acknowledged. “We cannot explain this reduction by the reduction in stroke that we saw because the number of deaths that are prevented by VKA are far larger than the number of strokes that are prevented. Moreover, the number of deaths were mainly heart failure or sudden deaths.”
Numbers of patients with major bleeding were also similar in the VKA and rivaroxaban groups (56 vs. 40 patients; P = .18), although numbers with fatal bleeding were lower with rivaroxaban (15 vs. 4, respectively).
By design, there were more physician interactions for monthly monitoring of INR in the VKA group, “but we do not believe such a large reduction can be explained entirely by increased health care contact,” he said. Moreover, there was no significant between-group difference in heart failure medications or hospitalizations or the need for valve replacement.
Almost a quarter (23%) of patients in the rivaroxaban group permanently discontinued the study drug versus just 6% in the VKA group.
Importantly, the mortality benefit emerged much later than in other trials and coincided with the time when the INR became therapeutic at about 3 years, Dr. Karthikeyan said. But it is unknown whether this is because of the INR or an unrelated effect.
More physician contact
Following the presentation, session cochair C. Michael Gibson, MD, Baim Institute for Clinical Research, Harvard Medical School, Boston, questioned the 23% discontinuation rate for rivaroxaban. “Is this really a superiority of warfarin or is this superiority of having someone come in and see their physician for a lot of checks on their INR?”
In response, Dr. Karthikeyan said that permanent discontinuation rates were about 20%-25% in shorter-duration direct oral anticoagulant trials, such as RELY, ROCKET-AF, and ARISTOLE, and exceeded 30% in ENGAGE-AF with 2.8 years’ follow-up.
“So, this is not new,” he said, adding that 31.4% of rivaroxaban patients did so for valve replacement surgery and subsequently received nonstudy VKA.
Dr. Lopes said it is important to keep in mind that INVICTUS enrolled a “very different population” that was younger (mean age, 50.5 years), was much more often female (72.3%), and had fewer comorbidities than patients with AFib who did not have rheumatic heart disease in the pivotal trials.
“It will be interesting to see the treatment effect according to mitral stenosis severity, since we had about 30% with mild mitral stenosis and additionally 18% of patients without mitral stenosis,” he added.
Co–principal investigator Stuart J. Connolly, MD, from the Population Health Research Institute, said physician contacts may be a factor but that the mortality difference was clear, highly significant, and sufficiently powered.
“What’s amazing is that what we’re seeing here is something that hasn’t been previously described with VKA or warfarin, which is that it reduces mortality,” he said in an interview.
Rivaroxaban has never been shown to reduce mortality in any particular condition, and a meta-analysis of other novel oral anticoagulants shows only a small reduction in mortality, caused almost completely by less intracranial hemorrhage than warfarin, he added. “So, we don’t think this is a problem with rivaroxaban. In some ways, rivaroxaban is an innocent bystander to a trial of warfarin in patients with rheumatic heart disease and atrial fibrillation.”
Dr. Connolly said more work is needed to explain the findings and analyses are planned to see which patients are at highest risk for death as well as looking at the relationship between INR control and outcomes.
“We need to do more research on what it is about VKA that could explain this,” he said. “Is it affecting the myocardium in some way, is it preventing fibrosis, is there some off target effect, not on the anticoagulation system, that could explain this?”
Athena Poppas, MD, chief of cardiology at Brown University, Providence, R.I., and past president of the American College of Cardiology, said “INVICTUS is an incredibly important study that needed to be done.”
“The results – though disappointing and surprising in some ways – I don’t think we can explain them away and change what we are doing right now,” she said in an interview.
Although warfarin is a cheap drug, Dr. Poppas said, it would be tremendously helpful to have an alternative treatment for these patients. Mechanistic studies are needed to understand the observed mortality advantage and low bleeding rates but that trials of other novel anticoagulants are also needed.
“But I’m not sure that will happen,” she added. “It’s unlikely to be industry sponsored, so it would be a very expensive lift with a low likelihood of success.”
In an editorial accompanying the paper, Gregory Y.H. Lip, MD, University of Liverpool (England), pointed out that observational data show similar or even higher risks for major bleeding with rivaroxaban than with warfarin. “To improve outcomes in these patients, we therefore need to look beyond anticoagulation alone or beyond a type of anticoagulation drug per se. Indeed, a one-size-fits-all approach may not be appropriate.”
The study was funded by an unrestricted grant from Bayer. Dr. Karthikeyan and Dr. Poppas reported no relevant conflicts of interest.

FROM ESC CONGRESS 2022
COVID-19 vaccine safe in patients with heart failure
Patients with heart failure (HF) who received two doses of COVID mRNA vaccines were not more likely to have worsening disease, venous thromboembolism, or myocarditis within 90 days than similar unvaccinated patients, in a case-control study in Denmark.
Moreover, in the 90 days after receiving the second shot, vaccinated patients were less likely to die of any cause, compared with unvaccinated patients during a similar 90-day period.
Caroline Sindet-Pedersen, PhD, Herlev and Gentofte Hospital, Hellerup, Denmark, and colleagues presented these findings at the annual congress of the European Society of Cardiology.
Major risk is not receiving vaccine
These results “confirm that the major risk for patients with HF is not receiving vaccination for COVID-19,” Marco Metra, MD, who was not involved with this research, said in an interview.
Dr. Metra was coauthor of an ESC guidance for the diagnosis and management of cardiovascular disease during the COVID-19 pandemic, published online ahead of print November 2021 in the European Heart Journal.
The guidance explains that patients with HF are at increased risk for hospitalization, need for mechanical ventilation, and death because of COVID-19, and that vaccination reduces the risk for serious illness from COVID-19, Dr. Sindet-Pedersen and colleagues explained in a press release from the ESC.
However, “concerns remain,” they added, “about the safety of the SARS-CoV-2 mRNA vaccines in heart failure patients, due to a perceived increased risk of cardiovascular side effects.”
The study findings suggest that “there should be no concern about cardiovascular side effects from mRNA vaccines in heart failure patients,” Dr. Sindet-Pedersen and colleagues summarized.
The results also “point to a beneficial effect of vaccination on mortality” and “indicate that patients with HF should be prioritized for COVID-19 vaccinations and boosters,” they added.
“There are ongoing concerns about the safety of COVID-19 vaccination in fragile patients and patients with heart failure,” said Dr. Metra, professor of cardiology and director of the Institute of Cardiology of the Civil Hospital and University of Brescia (Italy).
“These concerns are not based on evidence but just on reports of rare side effects (namely, myocarditis and pericarditis) in vaccinated people,” he added.
Dr. Metra also coauthored a position paper on COVID-19 vaccination in patients with HF from the Heart Failure Association of the ESC, which was published online October 2021 in the European Journal of Heart Failure.
“The current study,” he summarized, “shows a lower risk of mortality among patients vaccinated, compared with those not vaccinated.
“It has limitations,” he cautioned, “as it is not a prospective randomized study, but [rather] an observational one with comparison between vaccinated and not vaccinated patients with similar characteristics.
“However, it was done in a large population,” he noted, “and its results confirm that the major risk for patients with HF is not receiving vaccination for COVID-19.”
95% of patients with HF in Denmark double vaccinated
The group did not analyze the types of all-cause death in their study, Dr. Sindet-Pedersen clarified in an interview.
Other studies have shown that vaccines are associated with improved survival, she noted. For example, bacillus Calmette-Guérin vaccines and the measles vaccines have been linked with a decreased risk for nonspecific mortality in children, and influenza vaccines are associated with decreased all-cause mortality in patients with HF.
The rates of vaccination in this study were much higher than those for patients with HF in the United States.
In a study of 7,094 patients with HF seen at the Mount Sinai Health System between January 2021 and January 2022, 31% of patients were fully vaccinated with two doses and 14.8% had also received a booster, as per Centers for Disease Control and Prevention guidance. However, another 9.1% of patients were only partially vaccinated with one dose, and 45% remained unvaccinated by January 2022,
In the current study, “the uptake was very high,” Dr. Sindet-Pedersen noted, that is, “95% of the prevalent heart failure patients in 2021 received a vaccine.”
“It might be that the last 5% of the patients that did not receive a vaccine were too ill [terminal] to receive the vaccine,” she speculated, “or that was due to personal reasons.”
The researchers identified 50,893 patients with HF who were double vaccinated in 2021 and they matched them with 50,893 unvaccinated patients with HF in 2019 (prepandemic), with the same age, sex, HF duration, use of HF medications, ischemic heart disease, cancer, diabetes, atrial fibrillation, and admission with HF within 90 days.
Almost all patients in the vaccinated group received the Pfizer/BioNTech mRNA vaccine (92%) and the rest received the Moderna mRNA vaccine (8%), in 2021.
The patients had a mean age of 74, and 64% were men. They had HF for a median of 4.1 years.
During the 90-day follow-up, 1,311 patients in the unvaccinated cohort (2.56%) and 1,113 patients in the vaccinated cohort (2.23%) died; there was a significantly lower risk for all-cause death in the vaccinated cohort versus the unvaccinated cohort (–0.33 percentage points; 95% CI, –0.52 to –0.15 percentage points).
The risk for worsening heart failure was 1.1% in each group; myocarditis and venous thromboembolism were extremely rare, and risks for these conditions were not significantly different in the two groups.
The researchers and Dr. Metra declared they have no relevant financial disclosures. Dr. Metra is editor-in-chief of the European Journal of Heart Failure and senior consulting editor of the European Heart Journal.

The results also “point to a beneficial effect of vaccination on mortality” and “indicate that patients with HF should be prioritized for COVID-19 vaccinations and boosters,” they added.
“There are ongoing concerns about the safety of COVID-19 vaccination in fragile patients and patients with heart failure,” said Dr. Metra, professor of cardiology and director of the Institute of Cardiology of the Civil Hospital and University of Brescia (Italy).
“These concerns are not based on evidence but just on reports of rare side effects (namely, myocarditis and pericarditis) in vaccinated people,” he added.
Dr. Metra also coauthored a position paper on COVID-19 vaccination in patients with HF from the Heart Failure Association of the ESC, which was published online October 2021 in the European Journal of Heart Failure.
“The current study,” he summarized, “shows a lower risk of mortality among patients vaccinated, compared with those not vaccinated.
“It has limitations,” he cautioned, “as it is not a prospective randomized study, but [rather] an observational one with comparison between vaccinated and not vaccinated patients with similar characteristics.
“However, it was done in a large population,” he noted, “and its results confirm that the major risk for patients with HF is not receiving vaccination for COVID-19.”
95% of patients with HF in Denmark double vaccinated
The group did not analyze the types of all-cause death in their study, Dr. Sindet-Pedersen clarified in an interview.
Other studies have shown that vaccines are associated with improved survival, she noted. For example, bacillus Calmette-Guérin vaccines and the measles vaccines have been linked with a decreased risk for nonspecific mortality in children, and influenza vaccines are associated with decreased all-cause mortality in patients with HF.
The rates of vaccination in this study were much higher than those for patients with HF in the United States.
In a study of 7,094 patients with HF seen at the Mount Sinai Health System between January 2021 and January 2022, 31% of patients were fully vaccinated with two doses and 14.8% had also received a booster, as per Centers for Disease Control and Prevention guidance. However, another 9.1% of patients were only partially vaccinated with one dose, and 45% remained unvaccinated by January 2022,
In the current study, “the uptake was very high,” Dr. Sindet-Pedersen noted, that is, “95% of the prevalent heart failure patients in 2021 received a vaccine.”
“It might be that the last 5% of the patients that did not receive a vaccine were too ill [terminal] to receive the vaccine,” she speculated, “or that was due to personal reasons.”
The researchers identified 50,893 patients with HF who were double vaccinated in 2021 and they matched them with 50,893 unvaccinated patients with HF in 2019 (prepandemic), with the same age, sex, HF duration, use of HF medications, ischemic heart disease, cancer, diabetes, atrial fibrillation, and admission with HF within 90 days.
Almost all patients in the vaccinated group received the Pfizer/BioNTech mRNA vaccine (92%) and the rest received the Moderna mRNA vaccine (8%), in 2021.
The patients had a mean age of 74, and 64% were men. They had HF for a median of 4.1 years.
During the 90-day follow-up, 1,311 patients in the unvaccinated cohort (2.56%) and 1,113 patients in the vaccinated cohort (2.23%) died; there was a significantly lower risk for all-cause death in the vaccinated cohort versus the unvaccinated cohort (–0.33 percentage points; 95% CI, –0.52 to –0.15 percentage points).
The risk for worsening heart failure was 1.1% in each group; myocarditis and venous thromboembolism were extremely rare, and risks for these conditions were not significantly different in the two groups.
The researchers and Dr. Metra declared they have no relevant financial disclosures. Dr. Metra is editor-in-chief of the European Journal of Heart Failure and senior consulting editor of the European Heart Journal.

Patients with heart failure (HF) who received two doses of COVID mRNA vaccines were not more likely to have worsening disease, venous thromboembolism, or myocarditis within 90 days than similar unvaccinated patients, in a case-control study in Denmark.
Moreover, in the 90 days after receiving the second shot, vaccinated patients were less likely to die of any cause, compared with unvaccinated patients during a similar 90-day period.
Caroline Sindet-Pedersen, PhD, Herlev and Gentofte Hospital, Hellerup, Denmark, and colleagues presented these findings at the annual congress of the European Society of Cardiology.
Major risk is not receiving vaccine
These results “confirm that the major risk for patients with HF is not receiving vaccination for COVID-19,” Marco Metra, MD, who was not involved with this research, said in an interview.
Dr. Metra was coauthor of an ESC guidance for the diagnosis and management of cardiovascular disease during the COVID-19 pandemic, published online ahead of print November 2021 in the European Heart Journal.
The guidance explains that patients with HF are at increased risk for hospitalization, need for mechanical ventilation, and death because of COVID-19, and that vaccination reduces the risk for serious illness from COVID-19, Dr. Sindet-Pedersen and colleagues explained in a press release from the ESC.
However, “concerns remain,” they added, “about the safety of the SARS-CoV-2 mRNA vaccines in heart failure patients, due to a perceived increased risk of cardiovascular side effects.”

AXIOMATIC-SSP: Cautious optimism on factor XI inhibitor in stroke
The new factor XI inhibitor antithrombotic, milvexian (Bristol-Myers Squibb/Janssen), has shown promising results in a dose-finding phase 2 trial in patients with acute ischemic stroke or transient ischemic attack (TIA), when given in addition to dual antiplatelet therapy.
Although there was no significant reduction in the primary composite endpoint of ischemic stroke or incident infarct on brain MRI at 90 days with milvexian versus placebo in the AXIOMATIC-SSP study, with no apparent dose response, the drug numerically reduced the risk for symptomatic ischemic stroke at most doses. And doses from 25 mg to 100 mg twice daily showed an approximately 30% relative risk reduction in symptomatic ischemic stroke versus placebo.
Milvexian at 25 mg once and twice daily was associated with a low incidence of major bleeding; a moderate increase in bleeding was seen with higher doses.
There was no increase in severe bleeding, compared with placebo, and no fatal bleeding occurred any study group.
“Based on the observed efficacy signal for ischemic stroke, the bleeding profile, and the overall safety and tolerability, milvexian will be further studied in a phase 3 trial in a similar stroke population,” concluded lead investigator, Mukul Sharma, MD, associate professor of medicine at McMaster University, Hamilton, Ont.
Dr. Sharma presented the AXIOMATIC-SSP study results at the annual congress of the European Society of Cardiology.
New generation
Dr. Sharma explained that factor XI inhibitors represent the latest hope for a new generation of antithrombotic drugs with a low bleeding risk.
This has come about after observations that individuals born with factor XI deficiency have lower rates of ischemic stroke and thromboembolism than matched controls, without an offsetting increase in cerebral hemorrhage. In addition, spontaneous bleeding in these individuals is uncommon, and it is thought that factor XI is a strong driver of thrombus growth but plays a less important role in hemostasis, he noted.
“I think there is a tremendous niche for these drugs in stroke prevention,” Dr. Sharma said in an interview. “There is a huge unmet need in stroke patients for something other than aspirin over the long term which is effective but doesn’t cause hemorrhage.”
Dr. Sharma reported that antithrombotic efficacy of milvexian has already been demonstrated in a study of patients undergoing knee replacement in which the drug showed similar or increased efficacy in reducing thromboembolism, compared with enoxaparin, 40 mg, without an increase in major bleeding.
The aim of the current AXIOMATIC-SSP study was to find a dose suitable for use in the treatment of patients with acute stroke or TIA.
Patients with an acute ischemic stroke or TIA are at a high risk for another stroke in the first few months. Although antiplatelet drugs have reduced this event rate, there is still a significant residual risk for ischemic stroke, and the potential for major bleeding with additional antithrombotic therapies has limited the effectiveness of these options, Dr. Sharma explained. Currently, no anticoagulants are approved for noncardioembolic ischemic stroke prevention in the early phase.
The AXIOMATIC-SSP study included 2,366 patients within 48 hours of onset of a mild to moderate acute nonlacunar ischemic stroke. All patients had visible atherosclerotic plaque in a vessel supplying the affected brain region, and they all received background treatment with open-label aspirin and clopidogrel for 21 days, followed by open-label aspirin alone from days 22 to 90.
They were randomly assigned to one of five doses of milvexian (25, 50, 100, or 200 mg twice daily or 25 mg once daily) or placebo daily for 90 days.
The primary efficacy endpoint (symptomatic ischemic stroke or incident infarct on brain MRI) was numerically lower at the 50-mg and 100-mg twice-daily doses, and there was no apparent dose response (placebo, 16.6%; 25 mg once daily, 16.2%; 25 mg twice daily, 18.5%; 50 mg twice daily, 14.1%; 100 mg twice daily, 14.7%; 200 mg twice daily, 16.4%).
However, milvexian was associated with a numerically lower risk for clinical ischemic stroke at all doses except 200 mg twice daily, with doses from 25 to 100 mg twice daily showing an approximately 30% relative risk reduction versus placebo (placebo, 5.5%; 25 mg once daily, 4.6%; 25 mg twice daily, 3.8%; 50 mg twice daily, 4.0%; 100 mg twice daily, 3.5%; 200 mg twice daily, 7.7%).
The main safety endpoint was major bleeding, defined as Bleeding Academic Research Consortium type 3 or 5 bleeding. This was similar to placebo for milvexian 25 mg once daily and twice daily (all 0.6%) but was moderately increased in the 50 mg twice daily (1.5%), 100 mg twice daily (1.6%), and 200 mg twice daily (1.5%) groups.
Most major bleeding episodes were gastrointestinal. There was no increase in severe bleeding or symptomatic intracranial hemorrhage versus placebo, and no fatal bleeding occurred in any arm of the study.
Incremental improvement
On the hope for a class of drugs that reduce ischemic events without increasing bleeding, Dr. Sharma said, “we keep hoping for a home run where there is no increase in bleeding with a new generation of antithrombotic, but what we seem to get is an incremental improvement with each new class.
“Factor Xa inhibitors have a lower rate of bleeding, compared to warfarin. I think we will see another incremental improvement in bleeding with these new factor XI inhibitors and hopefully less of the more serious bleeding,” he said in an interview.
He pointed out that, in this study, milvexian was given on top of dual antiplatelet therapy. “In stroke neurology that sounds very risky as we know that going from a single antiplatelet to two antiplatelet agents increases the risk of bleeding and now we are adding in a third antithrombotic, but we feel comfortable doing it because of what has been observed in patients who have a genetic deficiency of factor XI – very low rates of spontaneous bleeding and they don’t bleed intracranially largely,” he added.
In addition to milvexian, another oral factor XI inhibitor, asundexian (Bayer), is also in development, and similar results were reported in a phase 2 stroke trial (PACIFIC-STROKE) at the same ESC session.
Both drugs are now believed to be going forward into phase 3 trials.
Discussant of the study at the ESC Hotline session, Giovanna Liuzzo, MD, Catholic University of Rome, highlighted the large unmet need for stroke therapies, noting that patients with acute stroke or TIA have a stroke recurrence rate of 5% at 30 days and 17% at 2 years. Although antiplatelet agents are recommended, the use of anticoagulants has been limited by concerns over bleeding risk, and the factor XI inhibitors are promising in that they have the potential for a lower bleeding risk.
She suggested that results from the AXIOMATIC-SSP could point to a dose of milvexian of 25 mg twice daily as a balance between efficacy and bleeding to be taken into larger phase 3 trials
“The jury is still out on the safety and efficacy of milvexian as an adjunct to dual antiplatelet therapy for the prevention of recurrent noncardioembolic stroke,” Dr. Liuzzo concluded. “Only large-scale phase 3 trials will establish the safety and efficacy of factor XI inhibitors in the prevention of venous and arterial thrombosis.”
The AXIOMATIC-SSP study was funded by the Bristol-Myers Squibb/Janssen alliance. Dr. Sharma reported research contracts with Bristol-Myers Squibb, Bayer, and AstraZeneca, and consulting fees from Janssen, Bayer, HLS Therapeutics, and Alexion.

Cannabis for pain linked to slight risk for arrhythmia
Patients who received a first prescription for medicinal cannabis for chronic pain were more likely to have new onset of arrhythmia – bradyarrhythmia, tachyarrhythmia, or a conduction disorder – within 6 months than were similar nonusers, in a new case-control study.
There were no between-group differences in the incidence of heart failure or acute coronary syndrome.
The researchers identified 5,071 patients in a national Danish registry who had filled at least one prescription for medicinal cannabis for chronic pain and matched each patient with five patients of the same sex, age range, and type of chronic pain who did not receive this therapy.
The relative risk for arrhythmia was 83% higher in those who used medicinal cannabis than it was in the other patients, study author Nina Nouhravesh, MD, told this news organization in an email.
However, the absolute risks for arrhythmia were slight – a 0.86% risk (95% confidence interval, 0.61%-1.1%) in medicinal cannabis users versus a 0.47% risk (95% CI, 0.38%-0.56%) in those who did not use medicinal cannabis.
“Since medical cannabis is a relatively new drug for a large market of patients with chronic pain, it is important to investigate and report serious side effects,” said Dr. Nouhravesh, from Gentofte University Hospital, Denmark.
The study results, she said, suggest that “there may be a previously unreported risk of arrhythmias following medical cannabis use.”
“Even though the absolute risk difference is small, both patients and physicians should have as much information as possible when weighing up the pros and cons of any treatment,” Dr. Nouhravesh said, adding that “the findings of this study raise concerns for both legal and illegal [cannabis] use worldwide.”
The results will be presented at the annual European Society of Cardiology (ESC) Congress 2022.
Too soon to tell?
However, Brian Olshansky, MD, who was not involved with this research, cautions that it is important to consider several study limitations before drawing clinical implications.
“Other data and reports have considered the possibility of arrhythmias in relationship to marijuana use, and the data go in both directions,” Dr. Olshansky, a clinical cardiac electrophysiologist and professor emeritus at University of Iowa Hospitals, Iowa City, pointed out in an email.
“Importantly, arrhythmias, by themselves, are not necessarily consequential,” he stressed. “In any case,” he added, the risks in the current study are “extraordinarily small.”
Sinus bradycardia, sinus tachycardia, and premature atrial or ventricular contractions could be totally benign, he said. On the other hand, arrhythmias may indicate the presence of atrial fibrillation, atrial flutter, ventricular tachycardia, and ventricular fibrillation, which are potentially dangerous.
There may be a specific “high risk” group who can develop potentially serious arrhythmias, Dr. Olshansky suggested.
“There is no evidence that any of these patients underwent or required any treatment for their arrhythmia or that stopping or starting the cannabinoids affected the arrhythmia one way or the other,” he said. “In addition, there is no dose/arrhythmia relationship.”
More patients in the medicinal cannabis group than in the nonuser group were also taking opioids (49% vs. 30%), nonsteroidal anti-inflammatory drugs (24% vs. 19%), antiepileptics (35% vs. 23%), or tricyclic antidepressants (11% vs. 4%), he noted.
In summary, according to Dr. Olshansky, “these data pose no obvious health concern and provide no vital knowledge for physicians prescribing cannabis.”
“My concern is that the information will be overblown,” he cautioned. “If the cannabinoid actually has benefit in terms of pain reduction, its use may be mitigated based on the fear of an arrhythmia that may occur – but the risk of an arrhythmia, in any event, is very small and undefined in terms of its seriousness.”
Cancer, musculoskeletal, and neurologic pain
For this analysis, the researchers identified 1.8 million patients in Denmark who were diagnosed with chronic pain between 2018 and 2021.
Of those, around 5,000 patients had claimed at least one prescription of medicinal cannabis (dronabinol 29%, cannabinoids 46%, or cannabidiol 25%).
The patients had a median age of 60 years, and 63% were women.
The cannabis users had been prescribed this therapy for musculoskeletal (35%), cancer (18%), neurological (14%), or other (33%) pain, Dr. Nouhravesh said.
The researchers and Dr. Olshansky have no relevant financial disclosures.

Patients who received a first prescription for medicinal cannabis for chronic pain were more likely to have new onset of arrhythmia – bradyarrhythmia, tachyarrhythmia, or a conduction disorder – within 6 months than were similar nonusers, in a new case-control study.
There were no between-group differences in the incidence of heart failure or acute coronary syndrome.
The researchers identified 5,071 patients in a national Danish registry who had filled at least one prescription for medicinal cannabis for chronic pain and matched each patient with five patients of the same sex, age range, and type of chronic pain who did not receive this therapy.
The relative risk for arrhythmia was 83% higher in those who used medicinal cannabis than it was in the other patients, study author Nina Nouhravesh, MD, told this news organization in an email.
However, the absolute risks for arrhythmia were slight – a 0.86% risk (95% confidence interval, 0.61%-1.1%) in medicinal cannabis users versus a 0.47% risk (95% CI, 0.38%-0.56%) in those who did not use medicinal cannabis.

FROM ESC CONGRESS 2022
Sacubitril/valsartan shows cognitive safety in heart failure: PERSPECTIVE
BARCELONA – Treatment of patients with chronic heart failure with sacubitril/valsartan (Entresto), a mainstay agent for people with this disorder, produced no hint of incremental adverse cognitive effects during 3 years of treatment in a prospective, controlled, multicenter study with nearly 600 patients, although some experts note that possible adverse cognitive effects of sacubitril were not an issue for many heart failure clinicians, even before the study ran.
The potential for an adverse effect of sacubitril on cognition had arisen as a hypothetical concern because sacubitril inhibits the human enzyme neprilysin. This activity results in beneficial effects for patients with heart failure by increasing levels of several endogenous vasoactive peptides. But neprilysin also degrades amyloid beta peptides and so inhibition of this enzyme could possibly result in accumulation of amyloid peptides in the brain with potential neurotoxic effects, which raised concern among some cardiologists and patients that sacubitril/valsartan could hasten cognitive decline.
Results from the new study, PERSPECTIVE, showed “no evidence that neprilysin inhibition increased the risk of cognitive impairment due to the accumulation of beta amyloid” in patients with heart failure with either mid-range or preserved ejection fraction,” John McMurray, MD, said at the annual congress of the European Society of Cardiology.
Dr. McMurray, professor of medical cardiology at the University of Glasgow, highlighted that the study enrolled only patients with heart failure with a left ventricular ejection fraction of greater than 40% because the study designers considered it “unethical” to withhold treatment with sacubitril/valsartan from patients with an ejection fraction of 40% or less (heart failure with reduced ejection fraction, HFrEF), whereas “no mandate” exists in current treatment guidelines for using sacubitril/valsartan in patients with heart failure and higher ejection fractions. He added that he could see no reason why the results seen in patients with higher ejection fractions would not also apply to those with HFrEF.
Reassuring results, but cost still a drag on uptake
“This was a well-designed trial” with results that are “very reassuring” for a lack of harm from sacubitril/valsartan, commented Biykem Bozkurt, MD, PhD, the study’s designated discussant and professor of medicine at Baylor College of Medicine, Houston. The findings “solidify the lack of risk and are very exciting for the heart failure community because the question has bothered a large number of people, especially older patients” with heart failure.
Following these results, “hopefully more patients with heart failure will receive” sacubitril/valsartan, agreed Dr. McMurray, but he added the caveat that the relatively high cost of the agent (which has a U.S. list price of roughly $6,000/year) has been the primary barrier to wider uptake of the drug for patients with heart failure. Treatment with sacubitril/valsartan is recommended in several society guidelines as a core intervention for patients with HFrEF and as a treatment option for patients with heart failure and higher ejection fractions.
“Cost remains the single biggest deterrent for use” of sacubitril/valsartan, agreed Dipti N. Itchhaporia, MD, director of disease management at the Hoag Heart and Vascular Institute in Newport Beach, Calif. “Concerns about cognitive impairment has not been why people have not been using sacubitril/valsartan,” Dr. Itchhaporia commented in an interview.
PERSPECTIVE enrolled patients with heart failure with an ejection fraction greater than 40% and at least 60 years old at any of 137 sites in 20 countries, with about a third of enrolled patients coming from U.S. centers. The study, which ran enrollment during January 2017–May 2019, excluded people with clinically discernible cognitive impairment at the time of entry.
Researchers randomized patients to either a standard regimen of sacubitril/valsartan (295) or valsartan (297) on top of their background treatment, with most patients also receiving a beta-blocker, a diuretic, and a statin. The enrolled patients averaged about 72 years of age, and more than one-third were at least 75 years old.
The study’s primary endpoint was the performance of these patients in seven different tests of cognitive function using a proprietary metric, the CogState Global Cognitive Composite Score, measured at baseline and then every 6 months during follow-up designed to run for 3 years on treatment (the researchers collected data for at least 30 months of follow-up from 71%-73% of enrolled patients). Average changes in these scores over time tracked nearly the same in both treatment arms and met the study’s prespecified criteria for noninferiority of the sacubitril valsartan treatment, Dr. McMurray reported. The results also showed that roughly 60% of patients in both arms had “some degree of cognitive impairment” during follow-up.
A secondary outcome measure used PET imaging to quantify cerebral accumulation of beta amyloid, and again the results met the study’s prespecified threshold for noninferiority for the patients treated with sacubitril/valsartan, said Dr. McMurray.
Another concern raised by some experts was the relatively brief follow-up of 3 years, and the complexity of heart failure patients who could face several other causes of cognitive decline. The findings “help reassure, but 3 years is not long enough, and I’m not sure the study eliminated all the other possible variables,” commented Dr. Itchhaporia.
But Dr. McMurray contended that 3 years represents robust follow-up in patients with heart failure who notoriously have limited life expectancy following their diagnosis. “Three years is a long time for patients with heart failure.”
The findings also raise the prospect of developing sacubitril/valsartan as an antihypertensive treatment, an indication that has been avoided until now because of the uncertain cognitive effects of the agent and the need for prolonged use when the treated disorder is hypertension instead of heart failure.
PERSPECTIVE was funded by Novartis, the company that markets sacubitril/valsartan (Entresto). Dr. McMurray has received consulting and lecture fees from Novartis and he and his institution have received research funding from Novartis. Dr. Bozkurt has been a consultant to numerous companies but has no relationship with Novartis. Dr. Itchhaporia had no disclosures.

Secondary CV prevention benefit from polypill promises global health benefit
Compared with separate medications in patients with a prior myocardial infarction, a single pill containing aspirin, a lipid-lowering agent, and an ACE inhibitor provided progressively greater protection from a second cardiovascular (CV) event over the course of a trial with several years of follow-up, according to results of a multinational trial.
“The curves began to separate at the very beginning of the trial, and they are continuing to separate, so we can begin to project the possibility that the results would be even more striking if we had an even longer follow-up,” said Valentin Fuster, MD, physician in chief, Mount Sinai Hospital, New York, who presented the results at the annual congress of the European Society of Cardiology.
By “striking,” Dr. Fuster was referring to a 24% reduction in the hazard ratio of major adverse CV events (MACE) for a trial in which patients were followed for a median of 3 years. The primary composite endpoint consisted of cardiovascular death, MI, stroke, and urgent revascularization (HR, 0.76; P = .02).
AS for the secondary composite endpoint, confined to CV death, MI, and stroke, use of the polypill linked to an even greater relative advantage over usual care (HR, 0.70; P = .005).
SECURE trial is latest test of polypill concept
A polypill strategy has been pursued for more than 15 years, according to Dr. Fuster. Other polypill studies have also generated positive results, but the latest trial, called SECURE, is the largest prospective randomized trial to evaluate a single pill combining multiple therapies for secondary prevention.
The degree of relative benefit has “huge implications for clinical care,” reported the ESC-invited commentator, Louise Bowman, MBBS, MD, professor of medicine and clinical trials, University of Oxford (England). She called the findings “in line with what was expected,” but she agreed that the results will drive practice change.
The SECURE trial, published online in the New England Journal of Medicine at the time of its presentation at the ESC congress, randomized 2,499 patients over the age of 65 years who had a MI within the previous 6 months and at least one other risk factor, such as diabetes mellitus, kidney dysfunction, or a prior coronary revascularization. They were enrolled at 113 participating study centers in seven European countries.
Multiple polypill versions permit dose titration
The polypill consisted of aspirin in a fixed dose of 100 mg, the HMG CoA reductase inhibitor atorvastatin, and the ACE inhibitor ramipril. For atorvastatin and ramipril, the target doses were 40 mg and 10 mg, respectively, but different versions of the polypill were available to permit titration to a tolerated dose. Usual care was provided by participating investigators according to ESC recommendations.
The average age of those enrolled was 76 years. Nearly one-third (31%) were women. At baseline, most had hypertension (77.9%), and the majority had diabetes (57.4%).
When the events in the primary endpoint were assessed individually, the polypill was associated with a 33% relative reduction in the risk of CV death (HR, 0.67; P = .03). The reductions in the risk of nonfatal MI (HR, 0.71) and stroke (HR, 0.70) were of the same general magnitude although they did not reach statistical significance. There was no meaningful reduction in urgent revascularization (HR, 0.96).
In addition, the reduction in all-cause mortality (HR, 0.97) was not significant.
The rate of adverse events over the course of the study was 32.7% in the polypill group and 31.6% in the usual-care group, which did not differ significantly. There was also no difference in types of adverse events, including bleeding and other adverse events of interest, according to Dr. Fuster.
Adherence, which was monitored at 6 and 24 months using the Morisky Medication Adherence Scale, was characterized as low, medium, or high. More patients in the polypill group reached high adherence at 6 months (70.6% vs. 62.7%) and at 24 months (74.1% vs. 63.2%). Conversely, fewer patients in the polypill group were deemed to have low adherence at both time points.
“Probably, adherence is the most important reason of how this works,” Dr. Fuster said. Although there were no substantial differences in lipid levels or in systolic or diastolic blood pressure between the two groups when compared at 24 months, there are several theories that might explain the lower event rates in the polypill group, including a more sustained anti-inflammatory effect from greater adherence.
One potential limitation was the open-label design, but Dr. Bowman said that this was unavoidable, given the difficulty of blinding and the fact that comparing a single pill with multiple pills was “the point of the study.” She noted that the 14% withdrawal rate over the course of the trial, which was attributed largely to the COVID-19 pandemic, and the lower than planned enrollment (2,500 vs. a projected 3,000 patients) are also limitations, prohibiting “a more robust result,” but she did not dispute the conclusions.
Polypill benefit documented in all subgroups
While acknowledging these limitations, Dr. Fuster emphasized the consistency of these results with prior polypill studies and within the study. Of the 16 predefined subgroups, such as those created with stratifications for age, sex, comorbidities, and country of treatment, all benefited to a similar degree.
“This really validates the importance of the study,” Dr. Fuster said.
In addition to the implications for risk management globally, Dr. Fuster and others, including Dr. Bowman, spoke of the potential of a relatively inexpensive polypill to improve care in resource-limited settings. Despite the move toward greater personalization of medicine, Dr. Fuster called “simplicity the key to global health” initiatives.
Salim Yusuf, MD, DPhil, a leader in international polypill research, agreed. He believes the supportive data for this approach are conclusive.
“There are four positive trials of the polypill now and collectively the data are overwhelmingly clear,” Dr. Yusuf, professor of medicine, McMaster University, Hamilton, Ont., said in an interview. “The polypill should be considered in secondary prevention as well as in primary prevention for high-risk individuals. We have estimated that, if it is used in even 50% of those who should get it, it would avoid 2 million premature deaths from CV disease and 6 million nonfatal events. The next step is to implement the findings.”
Dr. Fuster, Dr. Bowman, and Dr. Yusuf reported no potential conflicts of interest.
Compared with separate medications in patients with a prior myocardial infarction, a single pill containing aspirin, a lipid-lowering agent, and an ACE inhibitor provided progressively greater protection from a second cardiovascular (CV) event over the course of a trial with several years of follow-up, according to results of a multinational trial.
“The curves began to separate at the very beginning of the trial, and they are continuing to separate, so we can begin to project the possibility that the results would be even more striking if we had an even longer follow-up,” said Valentin Fuster, MD, physician in chief, Mount Sinai Hospital, New York, who presented the results at the annual congress of the European Society of Cardiology.
By “striking,” Dr. Fuster was referring to a 24% reduction in the hazard ratio of major adverse CV events (MACE) for a trial in which patients were followed for a median of 3 years. The primary composite endpoint consisted of cardiovascular death, MI, stroke, and urgent revascularization (HR, 0.76; P = .02).
AS for the secondary composite endpoint, confined to CV death, MI, and stroke, use of the polypill linked to an even greater relative advantage over usual care (HR, 0.70; P = .005).
SECURE trial is latest test of polypill concept
A polypill strategy has been pursued for more than 15 years, according to Dr. Fuster. Other polypill studies have also generated positive results, but the latest trial, called SECURE, is the largest prospective randomized trial to evaluate a single pill combining multiple therapies for secondary prevention.
The degree of relative benefit has “huge implications for clinical care,” reported the ESC-invited commentator, Louise Bowman, MBBS, MD, professor of medicine and clinical trials, University of Oxford (England). She called the findings “in line with what was expected,” but she agreed that the results will drive practice change.
The SECURE trial, published online in the New England Journal of Medicine at the time of its presentation at the ESC congress, randomized 2,499 patients over the age of 65 years who had a MI within the previous 6 months and at least one other risk factor, such as diabetes mellitus, kidney dysfunction, or a prior coronary revascularization. They were enrolled at 113 participating study centers in seven European countries.
Multiple polypill versions permit dose titration
The polypill consisted of aspirin in a fixed dose of 100 mg, the HMG CoA reductase inhibitor atorvastatin, and the ACE inhibitor ramipril. For atorvastatin and ramipril, the target doses were 40 mg and 10 mg, respectively, but different versions of the polypill were available to permit titration to a tolerated dose. Usual care was provided by participating investigators according to ESC recommendations.
The average age of those enrolled was 76 years. Nearly one-third (31%) were women. At baseline, most had hypertension (77.9%), and the majority had diabetes (57.4%).
When the events in the primary endpoint were assessed individually, the polypill was associated with a 33% relative reduction in the risk of CV death (HR, 0.67; P = .03). The reductions in the risk of nonfatal MI (HR, 0.71) and stroke (HR, 0.70) were of the same general magnitude although they did not reach statistical significance. There was no meaningful reduction in urgent revascularization (HR, 0.96).
In addition, the reduction in all-cause mortality (HR, 0.97) was not significant.
The rate of adverse events over the course of the study was 32.7% in the polypill group and 31.6% in the usual-care group, which did not differ significantly. There was also no difference in types of adverse events, including bleeding and other adverse events of interest, according to Dr. Fuster.
Adherence, which was monitored at 6 and 24 months using the Morisky Medication Adherence Scale, was characterized as low, medium, or high. More patients in the polypill group reached high adherence at 6 months (70.6% vs. 62.7%) and at 24 months (74.1% vs. 63.2%). Conversely, fewer patients in the polypill group were deemed to have low adherence at both time points.
“Probably, adherence is the most important reason of how this works,” Dr. Fuster said. Although there were no substantial differences in lipid levels or in systolic or diastolic blood pressure between the two groups when compared at 24 months, there are several theories that might explain the lower event rates in the polypill group, including a more sustained anti-inflammatory effect from greater adherence.

FROM ESC CONGRESS 2022
Long COVID mimics other postviral conditions
When Jaime Seltzer first heard about a new virus that was spreading globally early in 2020, she was on full alert. As an advocate for the post-viral condition known as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), she worried about a new wave of people having long-term disabilities.
“The hair on my arms stood on end,” said Ms. Seltzer, director of scientific and medical outreach at the advocacy group MEAction and a consultant researcher at Stanford University.
Ms. Seltzer, who has had ME/CFS herself, said she wondered.
Sure enough, later in 2020, reports began emerging about people with extreme fatigue, postexertion crashes, brain fog, unrefreshing sleep, and dizziness when standing up months after a bout with the then-new viral illness. Those same symptoms had been designated as “core criteria” of ME/CFS by the National Academy of Medicine in a 2015 report.
Now, advocates like Ms. Seltzer are hoping the research and medical communities will give ME/CFS and other postviral illnesses the same attention they have increasingly focused on long COVID.
The emergence of long COVID was no surprise to researchers who study ME/CFS, because the same set of symptoms has arisen after many other viruses.
“This for all the world looks like ME/CFS. We think they are frighteningly similar, if not identical,” said David M. Systrom, MD, a pulmonary and critical care medicine specialist at Brigham and Women’s Hospital in Boston, who studies people with both diagnoses.
The actual numbers are hard to determine, since many people who meet ME/CFS criteria aren’t formally diagnosed. But a combined analysis of data from several studies published in March found that about one in three people had fatigue and about one in five reported having a hard time with thinking and memory 12 or more weeks after they had COVID-19.
According to some estimates, about half of people with long COVID will meet the criteria for ME/CFS, whether they’re given that specific diagnosis or not.
Other conditions that often exist with ME/CFS are also being seen in people with long COVID, including postural orthostatic tachycardia syndrome, which causes people to feel dizzy when they stand, along with other symptoms; other problems with the autonomic nervous system, which controls body systems such as heart rate, blood pressure, and digestion, known together as dysautonomia; and a condition related to allergies called mast cell activation disorder.
Post–acute infection syndromes have been linked to a long list of viruses, including Ebola, the 2003-2004 SARS virus, and Epstein-Barr – the virus most commonly associated with ME/CFS.
The problem in clinical medicine is that once an infection has cleared, the teaching has been that the person should no longer feel sick, said Nancy G. Klimas, MD, director of the Institute for Neuro-Immune Medicine at Nova Southeastern University in Miami. “I was taught that there has to be an antigen [such as a viral protein] in the system to drive the immune system to make it create sickness, and the immune system should shut off when it’s done,” she said.
Thus, if virus is gone and other routine lab tests come up negative, doctors often deem the person’s reported symptoms to be psychological, which can upset patients, Anthony Komaroff, MD, of Brigham and Women’s Hospital in Boston, wrote in July 2021.
Only recently have doctors started to appreciate the idea that the immune system may be overreacting long term, Dr. Klimas said.
Now, long COVID appears to be speeding up that recognition. Dr. Systrom said he has “absolutely” seen a change in attitude among fellow doctors who had been skeptical of ME/CFS as a “real” illness because there’s no test for it.
“I’m very keenly aware of a large group of health care professionals who really had not bought into the concept of ME/CFS as a real disease who have had an epiphany of sorts with long COVID and now, in a backwards way, have applied that same thinking to their very same patients with ME/CFS,” he said.
Science showing ‘frighteningly similar’ symptoms
Dr. Systrom has spent several years researching how ME/CFS patients cannot tolerate exercise and now is doing similar studies in people with long COVID. “Several months into the pandemic, we began receiving reports of patients who had survived COVID and maybe even had a relatively mild disease ... and as the summer of 2020 moved into the fall, it became apparent that there was a subset of patients who for all the world appeared to meet ME/CFS clinical criteria,” he said.
Using bicycle exercise tests on long COVID patients with catheters placed in their veins, Dr. Systrom and associates have shown a lack of exercise capacity that isn’t caused by heart or lung disease but instead is related to abnormal nerves and blood vessels, just as they’d shown previously in ME/CFS patient.
Avindra Nath, MD, senior investigator and clinical director of intramural research at the National Institute of Neurological Disorders and Stroke, Bethesda, Md., was doing a deep-dive scientific study on ME/CFS when the COVID-19 pandemic hit. Since then, he›s begun another study using the same protocol and sophisticated laboratory measurement to evaluate people with long COVID.
“As terrible as [long COVID] is, it’s kind of a blessing in disguise for ME/CFS because there’s just so much overlap between the two and they could very well be in many ways one in the same thing. The problem with studying ME/CFS is oftentimes you didn’t know what the trigger was. You see patients many years later, then try to backtrack and find out what happened,” said Dr. Nath, a neuroimmunologist.
With long COVID, on the other hand, “we know when they got infected and when their symptoms actually started, so it becomes much more uniform. ... It gives us an opportunity to maybe solve certain things in a much more well-defined population and try to find answers.”
Advocacy groups want to see more.
In February 2021, Solve M.E. launched the Long COVID Alliance, made up of several organizations, companies, and people with a goal to influence policy and speed up research into a range of postviral illnesses.
Solve M.E. has also pushed for inclusion of language regarding ME/CFS and related conditions into congressional bills addressing long COVID, including those that call for funding of research and clinical care.
“On the political front, we’ve really capitalized on a moment in time in which we have the spotlight,” said Emily Taylor, vice president of advocacy and engagement for Solve M.E.
“One of the hardest parts about ME/CFS is how to show that it’s real when it’s invisible. Most people agree that COVID is real and therefore if somebody gets ME/CFS after COVID, it’s real,” she said.
The advocacy groups are now pushing for non-COVID postinfection illnesses to be included in efforts aimed at helping people with long COVID, with mixed results. For example, the RECOVER Initiative, established in February 2021 with $1.5 billion in funding from Congress to the National Institutes of Health, is specifically for studying long COVID and does not fund research into other postinfection illnesses, although representatives from the ME/CFS community are advisers.
Language addressing ME/CFS and other postinfectious chronic illnesses has been included in several long COVID bills now pending in Congress, including the Care for Long COVID Act in the Senate and its companion COVID-19 Long Haulers Act in the House. “Our goal is to push for passage of a long COVID bill by the end of the year,” Ms. Taylor said.

The problem with studying ME/CFS is oftentimes you didn’t know what the trigger was. You see patients many years later, then try to backtrack and find out what happened,” said Dr. Nath, a neuroimmunologist.
With long COVID, on the other hand, “we know when they got infected and when their symptoms actually started, so it becomes much more uniform. ... It gives us an opportunity to maybe solve certain things in a much more well-defined population and try to find answers.”
Advocacy groups want to see more.
In February 2021, Solve M.E. launched the Long COVID Alliance, made up of several organizations, companies, and people with a goal to influence policy and speed up research into a range of postviral illnesses.
Solve M.E. has also pushed for inclusion of language regarding ME/CFS and related conditions into congressional bills addressing long COVID, including those that call for funding of research and clinical care.
“On the political front, we’ve really capitalized on a moment in time in which we have the spotlight,” said Emily Taylor, vice president of advocacy and engagement for Solve M.E.
“One of the hardest parts about ME/CFS is how to show that it’s real when it’s invisible. Most people agree that COVID is real and therefore if somebody gets ME/CFS after COVID, it’s real,” she said.
The advocacy groups are now pushing for non-COVID postinfection illnesses to be included in efforts aimed at helping people with long COVID, with mixed results. For example, the RECOVER Initiative, established in February 2021 with $1.5 billion in funding from Congress to the National Institutes of Health, is specifically for studying long COVID and does not fund research into other postinfection illnesses, although representatives from the ME/CFS community are advisers.
Language addressing ME/CFS and other postinfectious chronic illnesses has been included in several long COVID bills now pending in Congress, including the Care for Long COVID Act in the Senate and its companion COVID-19 Long Haulers Act in the House. “Our goal is to push for passage of a long COVID bill by the end of the year,” Ms. Taylor said.

New international consensus document on treating OSA
The Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) has issued a new international consensus document (ICD) on obstructive sleep apnea (OSA). The objective is to improve the diagnosis and treatment of one of the most prevalent sleep disorders.
It provides a series of clinical guidelines to help health care professionals make the best decisions for adult patients with OSA. Notably, the authors propose changing the name from sleep apnea syndrome. In recommending the term OSA, they reintroduce the term “obstructive” – to differentiate the disorder from central sleep apnea – and remove the outdated word “syndrome.”
“The definition has also been changed, as it was a bit vague and difficult to understand. And there are significant changes to the treatment and to the diagnostic algorithms – one for primary care and another for sleep units,” Olga Mediano, MD, said in an interview. She is a SEPAR pulmonologist, first author of the ICD, and the coordinator of SEPAR 2022 Year of Intermediate Respiratory Care Units.
Diagnosis in primary care
The ICD indicates that all levels of care must be involved in the management of OSA, a condition in which complete or partial upper airway blockage occurs during sleep, causing the individual to stop breathing for a few seconds. These pauses, which produce hypoxia and sleep fragmentation, increase the risk of workplace and traffic accidents, affect cardiovascular health, and contribute to uncontrolled or resistant hypertension.
The recommendations in the ICD aim at increasing the role of primary care physicians so as to reduce underdiagnosis of OSA in primary care. “The vast majority of patients with OSA haven’t been diagnosed. In fact, those whom we have diagnosed are the patients with the most severe cases – in other words, patients who present with the most symptoms,” said Dr. Mediano. She explained that many patients with OSA don’t consider it a medical condition, so they do not go to the doctor.
“The other big problem is that, before, there was a preconceived notion of the typical OSA patient: A middle-aged obese man who’s fallen asleep in the waiting room. However, there are many other profiles: thin build, women. ... Sleep has a heterogeneous profile, and all profiles need to be known,” said Dr. Mediano. The difficulties in carrying out a sleep study with the various patients are an added problem that the new consensus document also seeks to resolve. “The step we’ve taken is to involve the primary care physician in super-simplified studies to reach more people,” she said. For this, the primary care site must work in coordination with a sleep unit.
“In the super-simplified study, the patient is given a machine to use at home; they hook themselves up to it when they go to sleep. This machine records the number of apnea episodes the patient experiences during the night, as well as the oxygen level. The next day, the patient returns the machine. The data are downloaded to a computer. The software analyzes the breathing pauses that the patient had during the night and automatically gives a series of values that, if very pronounced, as the document indicates, would lead to a diagnosis of OSA. Once diagnosed by a primary care physician, the patient is referred to a sleep unit where treatment can then be assessed,” explained Dr. Mediano.
Different treatments
The new ICD’s approach incorporates therapeutic alternatives as well. Until now, many consensus documents and clinical guidelines have focused on continuous positive airway pressure therapy, in which a machine delivers continuous airflow to help keep the patient’s airway open and unobstructed during sleep. Some guidelines recommend its use, and others do not. “However, in this new document, management of the patient is much more multidisciplinary. What changes, with respect to the treatment, is the philosophy. It’s not one single type of treatment; rather, other therapeutic options are kept in mind,” said Dr. Mediano.
First, treatment of reversible causes of OSA must be offered. The conditions that lead to OSA and that can be reversed are addressed. These include overweight and obesity; heavy drinking; tonsillar hypertrophy, or severe dental or facial alterations, for which surgery can be considered; and gastroesophageal reflux or hypothyroidism, both of which can be treated. “For example, the leading cause of sleep apnea is obesity. If we can get the patient to lose weight, that can end up making the OSA go away. What does the document say? Well, you have to try to implement intensive strategies regarding diet, exercise, etc. And if that’s not enough, you need to consider using drugs or even bariatric surgery,” said Dr. Mediano.
“If there’s no one definitive treatment, we highly recommend that all patients implement hygienic-dietary measures and then assess all the therapeutic options. In some cases, several can be in place at the same time,” she said. Various medical specialists can play a role in the treatment of OSA, said Dr. Mediano. They include otolaryngologists, maxillofacial surgeons, dentists, cardiologists, and neurophysiologists, to mention a few.

COVID to blame as U.S. life expectancy falls
All 50 states and the District of Columbia saw drops in life expectancy, according to the report from the Centers for Disease Control and Prevention’s National Center for Health Statistics.
The declines were mostly because of COVID-19 and “unintentional injuries,” such as drug overdoses.
The overall drop took national life expectancy from 78.8 years in 2019 to 77 years in 2020, the first year of the pandemic, ABC News reported.
States in the West and Northwest generally had higher life expectancy, with states in the South having the lowest.
Hawaii had the highest life expectancy at 80.7 years. It was followed by Washington, Minnesota, California, and Massachusetts. Mississippi had the lowest at 71.9 years, the figures show. The others in the bottom five were West Virginia, Louisiana, Alabama, and Kentucky.
In 2020, COVID-19 was the third-highest cause of death, leading to more than 350,000, the CDC reported earlier this year. At the same time, more people are dying annually from drug overdoses. A record 83,500 fatal overdoses were reported in 2020.
