Statins linked to reduced mortality in COVID-19
Treatment with statins was associated with a reduced risk of a severe or fatal course of COVID-19 by 30%, a meta-analysis of four published studies has shown.
In the analysis that included almost 9,000 COVID-19 patients, there was a significantly reduced risk for fatal or severe COVID-19 among patients who were users of statins, compared with nonusers (pooled hazard ratio, 0.70; 95% confidence interval, 0.53-0.94).
Based on the findings, “it may be time we shift our focus to statins as the potential therapeutic options in COVID-19 patients,” authors Syed Shahzad Hasan, PhD, University of Huddersfield (England), and Chia Siang Kow, MPharm, International Medical University, Kuala Lumpur, Malaysia, said in an interview.
The study was published online August 11 in The American Journal of Cardiology.
Moderate- to good-quality data
The analysis included four studies published up to July 27 of this year. Eligible studies included those with a cohort or case-control designs, enrolled patients with confirmed COVID-19, and had data available allowing comparison of the risk of severe illness and/or mortality among statin users versus nonusers in adjusted analyses, the authors noted.
The four studies – one of “moderate” quality and three of “good” quality – included a total of 8,990 COVID-19 patients.
In the pooled analysis, there was a significantly reduced risk for fatal or severe COVID-19 with use of statins, compared with non-use of statins (pooled HR, 0.70; 95% CI, 0.53-0.94).
Their findings also “discredited the suggestion of harms with the use of statins in COVID-19 patients,” the authors concluded.
“Since our meta-analysis included a fairly large total number of COVID-19 patients from four studies in which three are large-scale studies that adjusted extensively for multiple potential confounding factors, the findings can be considered reliable,” Dr. Hasan and Mr. Kow wrote in their article.
Based on the results, “moderate- to high-intensity statin therapy is likely to be beneficial” in patients with COVID-19, they said.
However, they cautioned that more data from prospective studies are needed to substantiate the findings and to determine the appropriate regimen for a statin in COVID-19 patients.
Yibin Wang, PhD, of the University of California, Los Angeles, said that “this is a very simple meta-analysis from four published studies which consistently reported a protective or neutral effect of statin usage on mortality or severe complications in COVID-19 patients.”
Although the scope of this meta-analysis was “quite limited, the conclusion was not unexpected, as most of the clinical analysis so far reported supports the benefits or safety of statin usage in COVID-19 patients,” Dr. Wang said in an interview.
Nonetheless, questions remain
While there is “almost no dispute” about the safety of continuing statin therapy in COVID-19 patients, it remains to be determined if statin therapy can be implemented as an adjuvant or independent therapy and a part of the standard care for COVID-19 patients regardless of their hyperlipidemia status, said Dr. Wang, who was not associated with Dr. Hasan’s and Mr. Kow’s research.
“While statin usage is associated with several beneficial effects such as anti-inflammation and cytoprotection, these effects are usually observed from long-term usage rather than short-term/acute administration. Therefore, prospective studies and randomized trials should be conducted to test the efficacy of stain usage for COVID-19 patients with mild to severe symptoms,” he noted.
“Considering the excellent record of statins as a safe and cheap drug, it is certainly a worthwhile effort to consider its broad-based usage for COVID-19 in order to lower the overall death and severe complications,” Dr. Wang concluded.
Guillermo Rodriguez-Nava, MD, department of internal medicine, AMITA Health Saint Francis Hospital, Evanston, Ill., is first author on one of the studies included in this meta-analysis.
The retrospective, single-center study found slower progression to death associated with atorvastatin in older patients with COVID-19 admitted to the ICU.
“Currently, there are hundreds of clinical trials evaluating a wide variety of pharmacological therapies for COVID-19. Unfortunately, these trials take time, and we are getting results in dribs and drabs,” Dr. Rodriguez-Nava said in an interview.
“In the meantime, the best available evidence is observational, and COVID-19 treatment regiments will continue to evolve. Whether atorvastatin is effective against COVID-19 is still under investigation. Nevertheless, clinicians should consider at least continuing them in patients with COVID-19,” he advised.
The study had no specific funding. Dr. Hasan, Mr. Kow, Dr. Wang, and Dr. Rodriguez-Nava disclosed no relationships relevant to this research.

Minidose edoxaban may safely cut AFib stroke risk in the frail, very elderly
suggests a randomized trial conducted in Japan.
Many of the study’s 984 mostly octogenarian patients were objectively frail with poor renal function, low body weight, a history of serious bleeding, or other conditions that made them poor candidates for regular-dose oral anticoagulation. Yet those who took the factor Xa inhibitor edoxaban (Savaysa) at the off-label dosage of 15 mg once daily showed a two-thirds drop in risk for stroke or systemic embolism (P < .001), compared with patients who received placebo. There were no fatal bleeds and virtually no intracranial hemorrhages.
For such high-risk patients with nonvalvular AFib who otherwise would not be given an OAC, edoxaban 15 mg “can be an acceptable treatment option in decreasing the risk of devastating stroke”; however, “it may increase the risk of gastrointestinal bleeding, so care should be given in every patient,” said Ken Okumura, MD, PhD. Indeed, the rate of gastrointestinal bleeding tripled among the patients who received edoxaban, compared with those given placebo, at about 2.3% per year versus 0.8% per year.
Although their 87% increased risk for major bleeding did not reach significance, it hit close, with a P value of .09 in the trial, called Edoxaban Low-Dose for Elder Care Atrial Fibrillation Patients (ELDERCARE-AF).
Dr. Okumura, of Saiseikai Kumamoto (Japan) Hospital, presented the study August 30 during the virtual annual congress of the European Society of Cardiology. He is lead author of an article describing the study, which was simultaneously published in the New England Journal of Medicine.
Many patients with AFib suffer strokes if they are not given oral anticoagulation because of “fear of major bleeding caused by standard OAC therapy,” Dr. Okumura noted. Others are inappropriately administered antiplatelets or anticoagulants at conventional dosages. “There is no standard of practice in Japan for patients like those in the present trial,” Dr. Okumura said. “However, I believe the present study opens a new possible path of thromboprophylaxis in such high-risk patients.”
Even with its relatively few bleeding events, ELDERCARE-AF “does suggest that the risk of the worst types of bleeds is not that high,” said Daniel E. Singer, MD, of Massachusetts General Hospital, Boston. “Gastrointestinal bleeding is annoying, and it will probably stop people from taking their edoxaban, but for the most part it doesn’t kill people.”
Moreover, he added, the trial suggests that low-dose edoxaban, in exchange for a steep reduction in thromboembolic risk, “doesn’t add to your risk of intracranial hemorrhage!”
ELDERCARE-AF may give practitioners “yet another reason to rethink” whether a low-dose DOAC such as edoxaban 15 mg/day may well be a good approach for such patients with AFib who are not receiving standard-dose OAC because of a perceived high risk for serious bleeding, said Dr. Singer, who was not involved in the study.
The trial randomly and evenly assigned 984 patients with AF in Japan to take either edoxaban 15 mg/day or placebo. The patients, who were at least 80 years old and had a CHADS2 score of 2 or higher, were judged inappropriate candidates for OAC at dosages approved for stroke prevention.
The mean age of the patients was 86.6, more than a decade older than patients “in the previous landmark clinical trials of direct oral anticoagulants,” and were 5-10 years older than the general AFib population, reported Dr. Okumura and colleagues.
Their mean weight was 52 kg, and mean creatinine clearance was 36.3 mL/min; 41% were classified as frail according to validated assessment tools.
Of the 303 patients who did not complete the trial, 158 voluntarily withdrew for various reasons. The withdrawal rate was similar in the two treatment arms. Outcomes were analyzed by intention to treat, the report noted.
The annualized rate of stroke or systemic embolism, the primary efficacy endpoint, was 2.3% for those who received edoxaban and 6.7% for the control group. Corresponding rates for the primary safety endpoint, major bleeding as determined by International Society on Thrombosis and Hemostasis criteria, were 3.3% and 1.8%, respectively.
“The question is, can the Food and Drug Administration act on this information? I doubt it can. What will be needed is to reproduce the study in a U.S. population to see if it holds,” Dr. Singer proposed.
“Edoxaban isn’t used much in the U.S. This could heighten interest. And who knows, there may be a gold rush,” he said, if the strategy were to pan out for the other DOACs, rivaroxaban (Xarelto), apixaban (Eliquis), and dabigatran (Pradaxa).
ELDERCARE-AF was funded by Daiichi Sankyo, from which Dr. Okumura reported receiving grants and personal fees; he also disclosed personal fees from Daiichi Sankyo, Boehringer Ingelheim, Bristol-Myers Squibb, Medtronic, Johnson & Johnson, and Bayer.

High mortality rates reported in large COVID-19 study
Factors including older age and certain comorbidities have been linked to more serious COVID-19 outcomes in previous research, and now a large dataset collected from hundreds of hospitals nationwide provides more detailed data regarding risk for mechanical ventilation and death.
History of pulmonary disease or smoking, interestingly, were not.
One expert urges caution when interpreting the results, however. Although the study found a number of risk factors for ventilation and mortality, she says the dataset lacks information on race and disease severity, and the sample may not be nationally representative.
The investigators hope their level of granularity will further assist researchers searching for effective treatments and clinicians seeking to triage patients during the COVID-19 pandemic.
The study was published online August 28 in Clinical Infectious Diseases.
COVID-19 and comorbidities
“What I found most illuminating was this whole concept of comorbid conditions. This provides suggestive data about who we need to worry about most and who we may need to worry about less,” study author Robert S. Brown Jr, MD, MPH, told Medscape Medical News.
Comorbid conditions included hypertension in 47% of patients, diabetes in 28%, and cardiovascular disease in 19%. Another 16% were obese and 12% had chronic kidney disease. People with comorbid obesity, chronic kidney disease, and cardiovascular disease were more likely to receive mechanical ventilation compared to those without a history of these conditions in an adjusted, multivariable logistic analysis.
With the exception of obesity, the same factors were associated with risk for death during hospitalization.
In contrast, hypertension, history of smoking, and history of pulmonary disease were associated with a lower risk of needing mechanical ventilation and/or lower risk for mortality.
Furthermore, people with liver disease, gastrointestinal diseases, and even autoimmune diseases – which are likely associated with immunosuppression – “are not at that much of an increased risk that we noticed it in our data,” Brown said.
“As I tell many of my patients who have mild liver disease, for example, I would rather have mild liver disease and be on immunosuppressant therapy than be an older, obese male,” he added.
Assessing data for people in 38 U.S. states, and not limiting outcomes to patients in a particular COVID-19 hot spot, was a unique aspect of the research, said Brown, clinical chief of the Division of Gastroenterology and Hepatology at Weill Cornell Medicine in New York City.
Brown, lead author Michael W. Fried, MD, from TARGET PharmaSolutions in Durham, North Carolina, and colleagues studied adults from a commercially available Target Real-World Evidence (RWE) dataset of nearly 70,000 patients. They examined hospital chargemaster data and ICD-10 codes for COVID-19 inpatients between February 15 and April 20.
This population tended to be older, with 60% older than 60 years. A little more than half of participants, 53%, were men.
Key findings
A total of 21% of patients died after a median hospital length of stay of 8 days.
Older patients were significantly more likely to die, particularly those older than 60 years (P < .0001).
“This confirms some of the things we know about age and its impact on outcome,” Brown said.
The risk for mortality among patients older than 60 years was 7.2 times that of patients between 18 and 40 years in an adjusted multivariate analysis. The risk for death for those between 41 and 60 years of age was lower (odds ratio [OR], 2.6), compared with the youngest cohort.
Men were more likely to die than women (OR, 1.5).
When asked if he was surprised by the high mortality rates, Brown said, “Having worked here in New York? No, I was not.”
Mechanical ventilation and mortality
Male sex, age older than 40 years, obesity, and presence of cardiovascular or chronic kidney disease were risk factors for mechanical ventilation.
Among the nearly 2,000 hospitalized adults requiring mechanical ventilation in the current report, only 27% were discharged alive. “The outcomes of people who are mechanically ventilated are really quite sobering,” Brown said.
People who ever required mechanical ventilation were 32 times more likely to die compared with others whose highest level of oxygenation was low-flow, high-flow, or no-oxygen therapy in an analysis that controlled for demographics and comorbidities.
Furthermore, patients placed on mechanical ventilation earlier – within 24 hours of admission – tended to experience better outcomes.
COVID-19 therapies?
Brown and colleagues also evaluated outcomes in patients who were taking either remdesivir or hydroxychloroquine. A total of 48 people were treated with remdesivir.
The four individuals receiving remdesivir who died were among 11 who were taking remdesivir and also on mechanical ventilation.
“The data for remdesivir is very encouraging,” Brown said.
Many more participants were treated with hydroxychloroquine, more than 4,200 or 36% of the total study population.
A higher proportion of people treated with hydroxychloroquine received mechanical ventilation, at 25%, versus 12% not treated with hydroxychloroquine.
The unadjusted mortality rate was also higher among those treated with the agent, at 25%, compared to 20% not receiving hydroxychloroquine.
The data with hydroxychloroquine can lead to two conclusions, Brown said: “One, it doesn’t work. Or two, it doesn’t work in the way that we use it.”
The researchers cautioned that their hydroxychloroquine findings must be interpreted carefully because those treated with the agent were also more likely to have comorbidities and greater COVID-19 disease severity.
“This study greatly contributes to understanding the natural course of COVID-19 infection by describing characteristics and outcomes of patients with COVID-19 hospitalized throughout the US,” the investigators note. “It identified categories of patients at greatest risk for poor outcomes, which should be used to prioritize prevention and treatment strategies in the future.”
Some limitations
“The findings that patients with hypertension and who were smokers had lower ventilation rates, and patients with hypertension, pulmonary disease, who were smokers had lower mortality risks was very surprising,” Ninez A. Ponce, PhD, MPP, told Medscape Medical News when asked to comment on the study.
Although the study identified multiple risk factors for ventilation and mortality, “unfortunately the dataset did not have race available or disease severity,” said Ponce, director of the UCLA Center for Health Policy Research and professor in the Department of Health Policy and Management at the UCLA Fielding School of Public Health.
“These omitted variables could have a considerable effect on the significance, magnitude, and direction of point estimates provided, so I would be cautious in interpreting the results as a picture of a nationally representative sample,” she said.
On a positive note, the study and dataset could illuminate the utility of medications used to treat COVID-19, Ponce said. In addition, as the authors note, “the data will expand over time.”
Brown has reported receiving grants and consulting for Gilead. Ponce has disclosed no relevant financial relationships.

Factors including older age and certain comorbidities have been linked to more serious COVID-19 outcomes in previous research, and now a large dataset collected from hundreds of hospitals nationwide provides more detailed data regarding risk for mechanical ventilation and death.
History of pulmonary disease or smoking, interestingly, were not.
One expert urges caution when interpreting the results, however. Although the study found a number of risk factors for ventilation and mortality, she says the dataset lacks information on race and disease severity, and the sample may not be nationally representative.
The investigators hope their level of granularity will further assist researchers searching for effective treatments and clinicians seeking to triage patients during the COVID-19 pandemic.
The study was published online August 28 in Clinical Infectious Diseases.
COVID-19 and comorbidities
“What I found most illuminating was this whole concept of comorbid conditions. This provides suggestive data about who we need to worry about most and who we may need to worry about less,” study author Robert S. Brown Jr, MD, MPH, told Medscape Medical News.
Comorbid conditions included hypertension in 47% of patients, diabetes in 28%, and cardiovascular disease in 19%. Another 16% were obese and 12% had chronic kidney disease. People with comorbid obesity, chronic kidney disease, and cardiovascular disease were more likely to receive mechanical ventilation compared to those without a history of these conditions in an adjusted, multivariable logistic analysis.
With the exception of obesity, the same factors were associated with risk for death during hospitalization.
In contrast, hypertension, history of smoking, and history of pulmonary disease were associated with a lower risk of needing mechanical ventilation and/or lower risk for mortality.
Furthermore, people with liver disease, gastrointestinal diseases, and even autoimmune diseases – which are likely associated with immunosuppression – “are not at that much of an increased risk that we noticed it in our data,” Brown said.
“As I tell many of my patients who have mild liver disease, for example, I would rather have mild liver disease and be on immunosuppressant therapy than be an older, obese male,” he added.
Assessing data for people in 38 U.S. states, and not limiting outcomes to patients in a particular COVID-19 hot spot, was a unique aspect of the research, said Brown, clinical chief of the Division of Gastroenterology and Hepatology at Weill Cornell Medicine in New York City.
Brown, lead author Michael W. Fried, MD, from TARGET PharmaSolutions in Durham, North Carolina, and colleagues studied adults from a commercially available Target Real-World Evidence (RWE) dataset of nearly 70,000 patients. They examined hospital chargemaster data and ICD-10 codes for COVID-19 inpatients between February 15 and April 20.
This population tended to be older, with 60% older than 60 years. A little more than half of participants, 53%, were men.
Key findings
A total of 21% of patients died after a median hospital length of stay of 8 days.
Older patients were significantly more likely to die, particularly those older than 60 years (P < .0001).
“This confirms some of the things we know about age and its impact on outcome,” Brown said.
The risk for mortality among patients older than 60 years was 7.2 times that of patients between 18 and 40 years in an adjusted multivariate analysis. The risk for death for those between 41 and 60 years of age was lower (odds ratio [OR], 2.6), compared with the youngest cohort.
Men were more likely to die than women (OR, 1.5).
When asked if he was surprised by the high mortality rates, Brown said, “Having worked here in New York? No, I was not.”
Mechanical ventilation and mortality
Male sex, age older than 40 years, obesity, and presence of cardiovascular or chronic kidney disease were risk factors for mechanical ventilation.
Among the nearly 2,000 hospitalized adults requiring mechanical ventilation in the current report, only 27% were discharged alive. “The outcomes of people who are mechanically ventilated are really quite sobering,” Brown said.
People who ever required mechanical ventilation were 32 times more likely to die compared with others whose highest level of oxygenation was low-flow, high-flow, or no-oxygen therapy in an analysis that controlled for demographics and comorbidities.
Furthermore, patients placed on mechanical ventilation earlier – within 24 hours of admission – tended to experience better outcomes.
COVID-19 therapies?
Brown and colleagues also evaluated outcomes in patients who were taking either remdesivir or hydroxychloroquine. A total of 48 people were treated with remdesivir.
The four individuals receiving remdesivir who died were among 11 who were taking remdesivir and also on mechanical ventilation.
“The data for remdesivir is very encouraging,” Brown said.
Many more participants were treated with hydroxychloroquine, more than 4,200 or 36% of the total study population.
A higher proportion of people treated with hydroxychloroquine received mechanical ventilation, at 25%, versus 12% not treated with hydroxychloroquine.
The unadjusted mortality rate was also higher among those treated with the agent, at 25%, compared to 20% not receiving hydroxychloroquine.
The data with hydroxychloroquine can lead to two conclusions, Brown said: “One, it doesn’t work. Or two, it doesn’t work in the way that we use it.”

Interstitial lung abnormalities linked to COPD exacerbations
Patients with chronic obstructive pulmonary disease who also had certain interstitial lung abnormalities experienced more exacerbations and reduced lung function than those without such abnormalities, findings from a retrospective study has shown.
Interstitial lung abnormalities (ILA) are considered precursor lesions of interstitial lung disease and previous studies suggested an association with poor outcomes among chronic obstructive pulmonary disease (COPD) patients, but data on long-term clinical relevance are limited, wrote Tae Seung Lee, MD, of Seoul (South Korea) National University Hospital, and colleagues.
In a study published in Chest, the researchers reviewed data from 363 COPD patients including 44 with equivocal ILA and 103 with definite ILA. Overall, the ILA patients were older and had poorer lung function than non-ILA patients. Patients received chest CT scan and longitudinal pulmonary function tests between January 2013 and December 2018.
Over an average follow-up period of 5.4 years, patients with ILA experienced significantly more acute COPD exacerbations than did those without ILA (adjusted odds ratio, 2.03). The percentages of frequent exacerbators among patients with no ILA, equivocal ILA, and definite ILA were 8.3%, 15.9%, and 20.4%, respectively.
“Acute exacerbation is an important event during the clinical course of COPD, because it is associated with temporary or persistent reductions in lung function, lower quality of life, hospitalization, and mortality,” the researchers noted.
In a multivariate analysis, the annual decline in lung function (FEV1) was –35.7 in patients with equivocal ILA, compared with –28.0 in patients with no ILA and –15.9 in those with definite ILA.
“This may be due to the distribution of the spirometric stages in each group, and to the resulting changes in lung function,” the researchers wrote. In this study, “the equivocal ILA group had a significantly lower baseline FEV1 than the other groups. In our study population, the lower the spirometric stage, the faster the annual decline in FEV1, consistent with the results of a prior prospective study of a COPD cohort.”
The findings were limited by several factors including the retrospective design and relatively small number of ILA patients, as well as the limited evaluation of ILA and potential for selection bias, the researchers noted. However, the result support the impact of ILA on exacerbations and accelerated decline in lung function in COPD patients.
The study received no outside funding. The researchers had no financial conflicts to disclose.

REALITY trial supports restrictive transfusion in anemic MI
in the landmark REALITY trial.
Randomized trial data already support a restrictive transfusion strategy in patients undergoing cardiac and noncardiac surgery, as well as in other settings. Those trials deliberately excluded patients with acute myocardial ischemia.
Cardiologists have been loath to adopt a restrictive strategy in the absence of persuasive supporting evidence because of a theoretic concern that low hemoglobin might be particularly harmful to ischemic myocardium. Anemia occurs in 5%-10% patients with MI, and clinicians have been eager for evidence-based guidance on how to best manage it.
“Blood is a precious resource and transfusion is costly, logistically cumbersome, and has side effects,” Philippe Gabriel Steg, MD, chair of the REALITY trial, noted in presenting the study results at the virtual annual congress of the European Society of Cardiology.
REALITY was the first-ever large randomized trial of a restrictive versus liberal transfusion strategy in acute MI. The study, which featured a noninferiority design, included 668 stable patients with acute MI and anemia with a hemoglobin of 7-10 g/dL at 35 hospitals in France and Spain. Participants were randomized to a restrictive strategy in which transfusion was withheld unless the hemoglobin dropped to 8 g/dL or less, or to a conventional liberal strategy triggered by a hemoglobin of 10 g/dL or lower. The transfusion target was a hemoglobin level of 8-10 g/dL in the restrictive strategy group and greater than 11 g/dL in the liberal transfusion group. In the restrictive transfusion group, 36% received at least one RBC transfusion, as did 87% in the liberal transfusion study arm. The restrictive strategy group used 414 fewer units of blood.
The two coprimary endpoints were 30-day major adverse cardiovascular events and cost-effectiveness. The 30-day composite of all-cause mortality, reinfarction, stroke, and emergency percutaneous coronary intervention for myocardial ischemia occurred in 11% of the restrictive transfusion group and 14% of the liberal transfusion group. The resultant 21% relative risk reduction established that the restrictive strategy was noninferior. Of note, all of the individual components of the composite endpoint numerically favored the restrictive approach.
In terms of safety, patients in the restrictive transfusion group were significantly less likely to develop an infection, by a margin of 0% versus 1.5%. The rate of acute lung injury was also significantly lower in the restrictive group: 0.3%, compared with 2.2%. The median hospital length of stay was identical at 7 days in both groups.
The cost-effectiveness analysis concluded that the restrictive transfusion strategy had an 84% probability of being both less expensive and more effective.
Patients were enrolled in REALITY regardless of whether they had active bleeding, as long as the bleeding wasn’t deemed massive and life-threatening. Notably, there was no difference in the results of restrictive versus liberal transfusion regardless of whether active bleeding was present, nor did baseline hemoglobin or the presence or absence of preexisting anemia affect the results.
Dr. Steg noted that a much larger randomized trial of restrictive versus liberal transfusion in the setting of acute MI with anemia is underway in the United States and Canada. The 3,000-patient MINT trial, sponsored by the National Institutes of Health, is testing the superiority of restrictive transfusion, rather than its noninferiority, as in REALITY. Results are a couple of years away.
“I think that will be an important piece of additional evidence,” he said.
Discussant Marco Roffi, MD, didn’t mince words.
“I really love the REALITY trial,” declared Dr. Roffi, professor and vice chairman of the cardiology department and director of the interventional cardiology unit at University Hospital of Geneva.
He ticked off a series of reasons: The trial addressed a common clinical dilemma about which there has been essentially no prior high-quality evidence, it provided convincing results, and it carried important implications for responsible stewardship of the blood supply.
“REALITY allows clinicians to comfortably refrain from transfusing anemic patients presenting with myocardial infarction, and this should lead to a reduction in the consumption of blood products,” Dr. Roffi said.
He applauded the investigators for their success in obtaining public funding for a study lacking a commercial hook. And as a clinical investigator, he was particularly impressed by one of the technical details about the REALITY trial: “I was amazed by the fact that the observed event rates virtually corresponded to the estimated ones used for the power calculations. This is rarely the case in such a trial.”
Dr. Roffi said the REALITY findings should have an immediate impact on clinical practice, as well as on the brand new 2020 ESC guidelines on the management of non–ST-elevation ACS issued during the ESC virtual congress.
The freshly inked guidelines state: “Based on inconsistent study results and the lack of adequately powered randomized, controlled trials, a restrictive policy of transfusion in anemic patients with MI may be considered.” As of today, Dr. Roffi argued, the phrase “may be considered” ought to be replaced by the stronger phrase “should be considered.”
During the discussion period, he was asked if it’s appropriate to extrapolate the REALITY results to patients undergoing transcatheter aortic valve replacement, among whom anemia is highly prevalent.
“I think this is a different patient population. Nevertheless, the concept of being restrictive is one that in my opinion now remains until proven otherwise. So we are being very restrictive in these patients,” he replied.
Asked about possible mechanisms by which liberal transfusion might have detrimental effects in acute MI patients, Dr. Steg cited several, including evidence that transfusion may not improve oxygen delivery to as great an extent as traditionally thought. There is also the risk of volume overload, increased blood viscosity, and enhanced platelet aggregation and activation, which could promote myocardial ischemia.
The REALITY trial was funded by the French Ministry of Health and the Spanish Ministry of Economy and Competitiveness with no commercial support. Outside the scope of the trial, Dr. Steg reported receiving research grants from Bayer, Merck, Servier, and Sanofi as well as serving as a consultant to numerous pharmaceutical companies.

Cardiologists have been loath to adopt a restrictive strategy in the absence of persuasive supporting evidence because of a theoretic concern that low hemoglobin might be particularly harmful to ischemic myocardium. Anemia occurs in 5%-10% patients with MI, and clinicians have been eager for evidence-based guidance on how to best manage it.
“Blood is a precious resource and transfusion is costly, logistically cumbersome, and has side effects,” Philippe Gabriel Steg, MD, chair of the REALITY trial, noted in presenting the study results at the virtual annual congress of the European Society of Cardiology.
REALITY was the first-ever large randomized trial of a restrictive versus liberal transfusion strategy in acute MI. The study, which featured a noninferiority design, included 668 stable patients with acute MI and anemia with a hemoglobin of 7-10 g/dL at 35 hospitals in France and Spain. Participants were randomized to a restrictive strategy in which transfusion was withheld unless the hemoglobin dropped to 8 g/dL or less, or to a conventional liberal strategy triggered by a hemoglobin of 10 g/dL or lower. The transfusion target was a hemoglobin level of 8-10 g/dL in the restrictive strategy group and greater than 11 g/dL in the liberal transfusion group. In the restrictive transfusion group, 36% received at least one RBC transfusion, as did 87% in the liberal transfusion study arm. The restrictive strategy group used 414 fewer units of blood.
The two coprimary endpoints were 30-day major adverse cardiovascular events and cost-effectiveness. The 30-day composite of all-cause mortality, reinfarction, stroke, and emergency percutaneous coronary intervention for myocardial ischemia occurred in 11% of the restrictive transfusion group and 14% of the liberal transfusion group. The resultant 21% relative risk reduction established that the restrictive strategy was noninferior. Of note, all of the individual components of the composite endpoint numerically favored the restrictive approach.
In terms of safety, patients in the restrictive transfusion group were significantly less likely to develop an infection, by a margin of 0% versus 1.5%. The rate of acute lung injury was also significantly lower in the restrictive group: 0.3%, compared with 2.2%. The median hospital length of stay was identical at 7 days in both groups.
The cost-effectiveness analysis concluded that the restrictive transfusion strategy had an 84% probability of being both less expensive and more effective.
Patients were enrolled in REALITY regardless of whether they had active bleeding, as long as the bleeding wasn’t deemed massive and life-threatening. Notably, there was no difference in the results of restrictive versus liberal transfusion regardless of whether active bleeding was present, nor did baseline hemoglobin or the presence or absence of preexisting anemia affect the results.
Dr. Steg noted that a much larger randomized trial of restrictive versus liberal transfusion in the setting of acute MI with anemia is underway in the United States and Canada. The 3,000-patient MINT trial, sponsored by the National Institutes of Health, is testing the superiority of restrictive transfusion, rather than its noninferiority, as in REALITY. Results are a couple of years away.
“I think that will be an important piece of additional evidence,” he said.
Discussant Marco Roffi, MD, didn’t mince words.
“I really love the REALITY trial,” declared Dr. Roffi, professor and vice chairman of the cardiology department and director of the interventional cardiology unit at University Hospital of Geneva.
He ticked off a series of reasons: The trial addressed a common clinical dilemma about which there has been essentially no prior high-quality evidence, it provided convincing results, and it carried important implications for responsible stewardship of the blood supply.
“REALITY allows clinicians to comfortably refrain from transfusing anemic patients presenting with myocardial infarction, and this should lead to a reduction in the consumption of blood products,” Dr. Roffi said.
He applauded the investigators for their success in obtaining public funding for a study lacking a commercial hook. And as a clinical investigator, he was particularly impressed by one of the technical details about the REALITY trial: “I was amazed by the fact that the observed event rates virtually corresponded to the estimated ones used for the power calculations. This is rarely the case in such a trial.”
Dr. Roffi said the REALITY findings should have an immediate impact on clinical practice, as well as on the brand new 2020 ESC guidelines on the management of non–ST-elevation ACS issued during the ESC virtual congress.
The freshly inked guidelines state: “Based on inconsistent study results and the lack of adequately powered randomized, controlled trials, a restrictive policy of transfusion in anemic patients with MI may be considered.” As of today, Dr. Roffi argued, the phrase “may be considered” ought to be replaced by the stronger phrase “should be considered.”
During the discussion period, he was asked if it’s appropriate to extrapolate the REALITY results to patients undergoing transcatheter aortic valve replacement, among whom anemia is highly prevalent.
“I think this is a different patient population. Nevertheless, the concept of being restrictive is one that in my opinion now remains until proven otherwise. So we are being very restrictive in these patients,” he replied.
Asked about possible mechanisms by which liberal transfusion might have detrimental effects in acute MI patients, Dr. Steg cited several, including evidence that transfusion may not improve oxygen delivery to as great an extent as traditionally thought. There is also the risk of volume overload, increased blood viscosity, and enhanced platelet aggregation and activation, which could promote myocardial ischemia.
The REALITY trial was funded by the French Ministry of Health and the Spanish Ministry of Economy and Competitiveness with no commercial support. Outside the scope of the trial, Dr. Steg reported receiving research grants from Bayer, Merck, Servier, and Sanofi as well as serving as a consultant to numerous pharmaceutical companies.
REPORTING FROM ESC CONGRESS 2020
Latest report adds almost 44,000 child COVID-19 cases in 1 week
according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.
The new cases bring the cumulative number of infected children to over 476,000, and that figure represents 9.5% of the over 5 million COVID-19 cases reported among all ages, the AAP and the CHA said in their weekly report. The cumulative number of children covers 49 states (New York is not reporting age distribution), the District of Columbia, New York City, Puerto Rico, and Guam.
From lowest to highest, the states occupying opposite ends of the cumulative proportion spectrum are New Jersey at 3.4% – New York City was lower with a 3.2% figure but is not a state – and Wyoming at 18.3%, the report showed.
Children represent more than 15% of all reported COVID-19 cases in five other states: Tennessee (17.1%), North Dakota (16.0%), Alaska (15.9%), New Mexico (15.7%), and Minnesota (15.1%). The states just above New Jersey are Florida (5.8%), Connecticut (5.9%), and Massachusetts (6.7%). Texas has a rate of 5.6% but has reported age for only 8% of confirmed cases, the AAP and CHA noted.
Children make up a much lower share of COVID-19 hospitalizations – 1.7% of the cumulative number for all ages – although that figure has been slowly rising over the course of the pandemic: it was 1.2% on July 9 and 0.9% on May 8. Arizona (4.1%) is the highest of the 22 states reporting age for hospitalizations and Hawaii (0.6%) is the lowest, based on the AAP/CHA data.
Mortality figures for children continue to be even lower. Nationwide, 0.07% of all COVID-19 deaths occurred in children, and 19 of the 43 states reporting age distributions have had no deaths yet. Pediatric deaths totaled 101 as of Aug. 27, the two groups reported.

First randomized trial reassures on ACEIs, ARBs in COVID-19
The first randomized study to compare continuing versus stopping ACE inhibitors or angiotensin receptor blockers (ARBs) for patients with COVID-19 has shown no difference in key outcomes between the two approaches.
The BRACE CORONA trial – conducted in patients had been taking an ACE inhibitor or an ARB on a long-term basis and who were subsequently hospitalized with COVID-19 – showed no difference in the primary endpoint of number of days alive and out of hospital among those whose medication was suspended for 30 days and those who continued undergoing treatment with these agents.
“Because these data indicate that there is no clinical benefit from routinely interrupting these medications in hospitalized patients with mild to moderate COVID-19, they should generally be continued for those with an indication,” principal investigator Renato Lopes, MD, of Duke Clinical Research Institute, Durham, N.C., concluded.
The BRACE CORONA trial was presented at the European Society of Cardiology Congress 2020 on Sept. 1.
Dr. Lopes explained that there are two conflicting hypotheses about the role of ACE inhibitors and ARBs in COVID-19.
One hypothesis suggests that use of these drugs could be harmful by increasing the expression of ACE2 receptors (which the SARS-CoV-2 virus uses to gain entry into cells), thus potentially enhancing viral binding and viral entry. The other suggests that ACE inhibitors and ARBs could be protective by reducing production of angiotensin II and enhancing the generation of angiotensin 1-7, which attenuates inflammation and fibrosis and therefore could attenuate lung injury.
The BRACE CORONA trial was an academic-led randomized study that tested two strategies: temporarily stopping the ACE inhibitor/ARB for 30 days or continuing these drugs for patients who had been taking these medications on a long-term basis and were hospitalized with a confirmed diagnosis of COVID-19.
The primary outcome was the number of days alive and out of hospital at 30 days. Patients who were using more than three antihypertensive drugs or sacubitril/valsartan or who were hemodynamically unstable at presentation were excluded from the study.
The trial enrolled 659 patients from 29 sites in Brazil. The mean age of patients was 56 years, 40% were women, and 52% were obese. ACE inhibitors were being taken by 15% of the trial participants; ARBs were being taken by 85%. The median duration of ACE inhibitor/ARB treatment was 5 years.
Patients were a median of 6 days from COVID-19 symptom onset. For 30% of the patients, oxygen saturation was below 94% at entry. In terms of COVID-19 symptoms, 57% were classified as mild, and 43% as moderate.
Those with severe COVID-19 symptoms who needed intubation or vasoactive drugs were excluded. Antihypertensive therapy would generally be discontinued in these patients anyway, Dr. Lopes said.
Results showed that the average number of days alive and out of hospital was 21.9 days for patients who stopped taking ACE inhibitors/ARBs and 22.9 days for patients who continued taking these medications. The average difference between groups was –1.1 days.
The average ratio of days alive and out of hospital between the suspending and continuing groups was 0.95 (95% CI, 0.90-1.01; P = .09).
The proportion of patients alive and out of hospital by the end of 30 days in the suspending ACE inhibitor/ARB group was 91.8% versus 95% in the continuing group.
A similar 30-day mortality rate was seen for patients who continued and those who suspended ACE inhibitor/ARB therapy, at 2.8% and 2.7%, respectively (hazard ratio, 0.97). The median number of days that patients were alive and out of hospital was 25 in both groups.
Dr. Lopes said that there was no difference between the two groups with regard to many other secondary outcomes. These included COVID-19 disease progression (need for intubation, ventilation, need for vasoactive drugs, or imaging results) and cardiovascular endpoints (MI, stroke, thromboembolic events, worsening heart failure, myocarditis, or hypertensive crisis).
“Our results endorse with reliable and more definitive data what most medical and cardiovascular societies are recommending – that patients do not stop ACE inhibitor or ARB medication. This has been based on observational data so far, but BRACE CORONA now provides randomized data to support this recommendation,” Dr. Lopes concluded.
Dr. Lopes noted that several subgroups had been prespecified for analysis. Factors included age, obesity, difference between ACE inhibitors/ARBs, difference in oxygen saturation at presentation, time since COVID-19 symptom onset, degree of lung involvement on CT, and symptom severity on presentation.
“We saw very consistent effects of our main findings across all these subgroups, and we plan to report more details of these in the near future,” he said.
Protective for older patients?
The discussant of the study at the ESC Hotline session, Gianfranco Parati, MD, University of Milan-Bicocca and San Luca Hospital, Milan, congratulated Lopes and his team for conducting this important trial at such a difficult time.
He pointed out that patients in the BRACE CORONA trial were quite young (average age, 56 years) and that observational data so far suggest that ACE inhibitors and ARBs have a stronger protective effect in older COVID-19 patients.
He also noted that the percentage of patients alive and out of hospital at 30 days was higher for the patients who continued on treatment in this study (95% vs. 91.8%), which suggested an advantage in maintaining the medication.
Dr. Lopes replied that one-quarter of the population in the BRACE CORONA trial was older than 65 years, which he said was a “reasonable number.”
“Subgroup analysis by age did not show a significant interaction, but the effect of continuing treatment does seem to be more favorable in older patients and also in those who were sicker and had more comorbidities,” he added.
Dr. Parati also suggested that it would have been difficult to discern differences between ACE inhibitors and ARBs in the BRACE CORONA trial, because so few patents were taking ACE inhibitors; the follow-up period of 30 days was relatively short, inasmuch as these drugs may have long-term effects; and it would have been difficult to show differences in the main outcomes used in the study – mortality and time out of hospital – in these patients with mild to moderate disease.
Franz H. Messerli, MD, and Christoph Gräni, MD, University of Bern (Switzerland), said in a joint statement: “The BRACE CORONA trial provides answers to what we know from retrospective studies: if you have already COVID, don’t stop renin-angiotensin system blocker medication.”
But they added that the study does not answer the question about the risk/benefit of ACE inhibitors or ARBs with regard to possible enhanced viral entry through the ACE2 receptor. “What about all those on these drugs who are not infected with COVID? Do they need to stop them? We simply don’t know yet,” they said.
Dr. Messerli and Dr. Gräni added that they would like to see a study that compared patients before SARS-CoV-2 infection who were without hypertension, patients with hypertension who were taking ACE inhibitors or ARBs, and patients with hypertension taking other antihypertensive drugs.
The BRACE CORONA trial was sponsored by D’Or Institute for Research and Education and the Brazilian Clinical Research Institute. Dr. Lopes has disclosed no relevant financial relationships.

Pandemic worsens disparities in GI and liver disease
Suspension of disease screening and nonurgent procedures because of the COVID-19 pandemic will negatively impact long-term outcomes of GI and liver disease, and people of color will be disproportionately affected, according to a leading expert.
Novel, multipronged approaches are needed to overcome widening disparities in gastroenterology and hepatology, said Rachel Issaka, MD, of Fred Hutchinson Cancer Research Center in Seattle.
“The COVID-19 pandemic has led to unprecedented drops in breast, colorectal, and cervical cancer screenings,” Dr. Issaka said during an AGA FORWARD Program webinar. Screening rates for these diseases are down 83%-90%, she said.
“Certainly this creates a backlog of cancer screenings that need to occur, which poses very significant challenges for health systems as they’re adapting to this new state of health care that we have to provide,” Dr. Issaka said.
During her presentation, Dr. Issaka first addressed pandemic-related issues in colorectal cancer (CRC).
The sudden decrease in colonoscopies has already affected diagnoses, she said, as 32% fewer cases of CRC were diagnosed in April 2020 compared with April 2019, a finding that is “obviously very concerning.” All downstream effects remain to be seen; however, one estimate suggests that over the next decade, delayed screening may lead to an additional 4,500 deaths from CRC.
“These effects are particularly noticeable in medically underserved communities where CRC morbidity and mortality are highest,” Dr. Issaka wrote, as coauthor of a study published in Gastrointestinal Endoscopy.
Dr. Issaka and colleagues predict that the pandemic will likely worsen “persistent CRC disparities” in African-American and Hispanic communities, including relatively decreased screening participation, delayed follow-up of abnormal stool results, limited community-based research and partnerships, and limited community engagement and advocacy.
“COVID-19 related pauses in medical care, as well as shifts in resource allocation and workforce deployment, threaten decades worth of work to improve CRC disparities in medically underserved populations,” wrote Dr. Issaka and colleagues.
Dr. Issaka described similar issues in hepatology. She referred to a recent opinion article by Tapper and colleagues, which predicted that the COVID-19 pandemic will impact patients with liver disease in three waves: first, by delaying liver transplants, elective procedures, imaging, and routine patient follow-up; second, by increasing emergent decompensations, transplant wait-list dropouts, and care deferrals; and third, by losing patients to follow-up, resulting in missed diagnoses, incomplete cancer screening, and progressive disease.
“This could disproportionately impact Black, Hispanic, and Native-American populations, who may have already had difficulty accessing [liver care],” Dr. Issaka said.
To mitigate growing disparities, Dr. Issaka proposed a variety of strategies for CRC and liver disease.
For CRC screening, Dr. Issaka suggested noninvasive modalities, including mailed fecal immunochemical tests (FIT), with focused follow-up on patients with highest FIT values. For those conducting CRC research, Dr. Issaka recommended using accessible technology, engaging with community partners, providing incentives where appropriate, and other methods. For cirrhosis care, Dr. Issaka suggested that practitioners turn to telehealth and remote care, including weight monitoring, cognitive function testing, home medication delivery, and online education.
More broadly, Dr. Issaka called for universal health insurance not associated with employment, research funding for health disparities, sustainable employment wages, climate justice, desegregation of housing, and universal broadband Internet.
“The solutions to these problems are multipronged,” Dr. Issaka said. “Some will happen locally; for instance, well-executed planning around telehealth. Some will happen at the state level through opportunities like advocacy or even just reaching out to your own [congressional representative]. And then some will also happen programmatically – How can we as a health system begin to leverage something like mailed FIT?”
Finally, Dr. Issaka suggested that tools from another branch of science can help improve screening rates.
“We don’t, in medicine, tap into the benefits of behavioral psychology enough,” she said. “That’s a great discipline with really great tools that we can all use.”
Dr. Issaka described the power of community, in that people are more likely to undergo screening if they know how many others in their community are also being screened.
“I think as much as we can gather those kinds of data and share those with individuals to provide reassurance about the safety and importance of screening, I think [that] will help,” she said.

Suspension of disease screening and nonurgent procedures because of the COVID-19 pandemic will negatively impact long-term outcomes of GI and liver disease, and people of color will be disproportionately affected, according to a leading expert.
Novel, multipronged approaches are needed to overcome widening disparities in gastroenterology and hepatology, said Rachel Issaka, MD, of Fred Hutchinson Cancer Research Center in Seattle.
“The COVID-19 pandemic has led to unprecedented drops in breast, colorectal, and cervical cancer screenings,” Dr. Issaka said during an AGA FORWARD Program webinar. Screening rates for these diseases are down 83%-90%, she said.
“Certainly this creates a backlog of cancer screenings that need to occur, which poses very significant challenges for health systems as they’re adapting to this new state of health care that we have to provide,” Dr. Issaka said.

Obesity boosts risks in COVID-19 from diagnosis to death
A new analysis of existing research confirms a stark link between excess weight and COVID-19:
Obese patients faced the greatest bump in risk on the hospitalization front, with their odds of being admitted listed as 113% higher. The odds of diagnosis, ICU admission, and death were 46% higher (odds ratio [OR], 1.46; 95% confidence interval [CI], 1.30-1.65; P < .0001); 74% higher (OR, 1.74, CI, 1.46-2.08, P < .0001); 48% (OR, 1.48, CI, 1.22–1.80, P < .001, all pooled analyses and 95% CI), respectively. All differences were highly significantly different, investigators reported in a systematic review and meta-analysis published online Aug. 26 in Obesity Reviews.
“Essentially, these are pretty scary statistics,” nutrition researcher and study lead author Barry M. Popkin, PhD, of the University of North Carolina at Chapel Hill School of Public Health, said in an interview. “Other studies have talked about an increase in mortality, and we were thinking there’d be a little increase like 10% – nothing like 48%.”
According to the Johns Hopkins University of Medicine tracker, nearly 6 million people in the United States had been diagnosed with COVID-19 as of Aug. 30. The number of deaths had surpassed 183,000.
The authors of the new review launched their project to better understand the link between obesity and COVID-19 “all the way from being diagnosed to death,” Dr. Popkin said, adding that the meta-analysis is the largest of its kind to examine the link.
Dr. Popkin and colleagues analyzed 75 studies during January to June 2020 that tracked 399,461 patients (55% of whom were male) diagnosed with COVID-19. They found that 18 of 20 studies linked obesity with a 46% higher risk of diagnosis, but Dr. Popkin cautioned that this may be misleading. “I suspect it’s because they’re sicker and getting tested more for COVID,” he said. “I don’t think obesity enhances your likelihood of getting COVID. We don’t have a biological rationale for that.”
The researchers examined 19 studies that explored a link between obesity and hospitalization; all 19 found a higher risk of hospitalization in patients with obesity (pooled OR, 2.13). Twenty-one of 22 studies that looked at ICU admissions discovered a higher risk for patients with obesity (pooled OR, 1.74). And 27 of 35 studies that examined COVID-19 mortality found a higher death rate in patients with obesity (pooled OR, 1.48).
The review also looked at 14 studies that examined links between obesity and administration of invasive mechanical ventilation. All the studies found a higher risk for patients with obesity (pooled OR, 1.66; 95% CI, 1.38-1.99; P < .0001).
Could socioeconomic factors explain the difference in risk for people with obesity? It’s not clear. According to Dr. Popkin, most of the studies don’t examine factors such as income. While he believes physical factors are the key to the higher risk, he said “there’s clearly a social side to this.”
On the biological front, it appears that “the immune system is much weaker if you’re obese,” he said, and excess weight may worsen the course of a respiratory disease such as COVID-19 because of lung disorders such as sleep apnea.
In addition to highlighting inflammation and a weakened immune system, the review offers multiple explanations for why patients with obesity face worse outcomes in COVID-19. It may be more difficult for medical professionals to care for them in the hospital because of their weight, the authors wrote, and “obesity may also impair therapeutic treatments during COVID-19 infections.” The authors noted that ACE inhibitors may worsen COVID-19 in patients with type 2 diabetes.
The researchers noted that “potentially the vaccines developed to address COVID-19 will be less effective for individuals with obesity due to a weakened immune response.” They pointed to research that suggests T-cell responses are weaker and antibody titers wane at a faster rate in people with obesity who are vaccinated against influenza.
Pulmonologist Joshua L. Denson, MD, MS, of Tulane University, New Orleans, praised the review in an interview, but noted that some of the included studies have wide confidence intervals. One study that links COVID-19 to a sixfold higher mortality rate (OR, 6.29) has a confidence interval of 1.76-22.45.
Dr. Denson said he’s seen about 100 patients with COVID-19, and many are obese and have metabolic syndrome.
Like the authors of the study, he believes higher levels of inflammation play a crucial role in making these patients more vulnerable. “For whatever reason, the virus tends to really like that state. That’s driving these people to get sick,” he said.
Moving forward, Dr. Popkin urged physicians to redouble their efforts to warn patients about the risks of obesity and the importance of healthy eating. He also said COVID-19 vaccine researchers must stratify obese vs. nonobese subjects in clinical trials.
The review was funded by Bloomberg Philanthropies, the Carolina Population Center, World Bank, and Saudi Health Council. The review authors report no relevant disclosures. Dr. Denson reports no relevant disclosures.

FROM OBESITY REVIEWS
HOME-PE trial clarifies which pulmonary embolism patients to treat at home
The pragmatic Hestia criteria proved as safe as the more structured, points-based simplified Pulmonary Embolism Severity Index (sPESI) score for selection of patients with acute pulmonary embolism for outpatient care in the large, randomized HOME-PE trial presented at the virtual annual congress of the European Society of Cardiology.
“These results support outpatient management of acute pulmonary embolism patients using either the Hestia method or the sPESI score with the option for the physician-in-charge to override the decision. In hospitals organized for outpatient management, both triaging strategies enable more than a third of pulmonary embolism patients to be managed at home with a low rate of complications,” Pierre-Marie Roy, MD, said in presenting the HOME-PE findings.
The study clarifies a transatlantic controversy regarding how best to triage patients with acute pulmonary embolism (PE) for outpatient care. The answer? It’s basically a tie between the points-based sPESI score recommended in the current ESC guidelines (Eur Respir J. 2019 Oct 9;54[3]:1901647) and the Hestia method endorsed in the American College of Chest Physician guidelines (Chest. 2016 Feb;149[2]:315-52).
The sPESI is a validated tool that grants 1 point each for age over 80 years, background cardiopulmonary disease, a systolic blood pressure below 100 mm Hg, cancer, a heart rate of 110 bpm or more, and an oxygen saturation level below 90%. A patient needs a score of zero to be eligible for outpatient management. In contrast, the Hestia method relies upon 11 simple bedside criteria rather than a points system, explained Dr. Roy of University Hospital of Angers, France (J Thromb Haemost. 2011 Aug;9[8]:1500-7).
HOME-PE was a randomized, open-label, noninferiority trial conducted at 26 hospitals in France, Belgium, Switzerland, and the Netherlands. The study included 1,974 patients presenting to the emergency department with non–high-risk acute PE as defined by hemodynamic stability. About 39% of patients in the Hestia group were eligible for outpatient care on the basis of ‘no’ answers regarding all 11 criteria, while 48% of patients had an sPESI score of 0 and were thus initially considered appropriate for outpatient management.
However, the investigators recognized that no scoring system for acute PE is perfect, and that the judgment of a physician with extensive experience in managing this life-threatening condition counts for a lot. So they stipulated that a patient’s physician-in-charge could overrule a decision for early discharge. This happened 29% of the time in patients with a sPESI score of 0, as compared with a 3% overrule rate with the Hestia rule. The physician-in-charge also moved small numbers of patients who were Hestia or sPESI positive into the outpatient care group. As a result, a similar proportion of patients in both groups were discharged home within 24 hours for outpatient treatment: 38% of the total Hestia group and 37% in the sPESI arm.
Major adverse event rates were reassuringly low in both groups managed on an outpatient basis. The composite of recurrent venous thromboembolism, bleeding, or death within 30 days occurred in 1.3% of Hestia outpatients and 1.1% of sPESI outpatients. Among patients managed in the hospital, these rates were 5.6% in the Hestia group and 4.7% in the sPESI group.
Discussant Stavros V. Konstantinides, MD, who chaired the ESC guideline committee, asked rhetorically, “who’s happy with the HOME-PE trial? I think everybody.”
“The Hestia criteria integrate the feasibility of family support of the individual patient. This is a good thing. And eligibility based on the Hestia criteria, unlike sPESI, does not require age younger than 80 years or no cancer, and it appears from the HOME-PE study that this is okay,” observed Dr. Konstantinides of the Center for Thrombosis and Hemostasis at the University of Mainz (Germany).
In an interview, Hadley Wilson, MD, called the HOME-PE trial “transformative” and predicted it will change clinical practice. He was particularly impressed with the high quality of the trial, noting that 87% of participants managed as outpatients received a direct oral anticoagulant.
The Hestia rule is simpler and more user-friendly. And greater use of this triaging strategy might have advantages in terms of economics and health care utilization by potentially encouraging movement of decision-making regarding outpatient management of acute PE out of the hospital wards and into emergency departments, said Dr. Wilson, executive vice chair of the Sanger Heart and Vascular Institute and a cardiologist at the University of North Carolina at Chapel Hill.
Dr. Roy reported receiving research grants to conduct HOME-PE from the French Ministry of Health, the study sponsor. In addition, he is on scientific advisory boards and/or speakers’ panels for Bayer, Boehringer Ingelheim, Bristol-Myers Squibb, Pfizer, Aspen, Daiichi Sankyo, and Sanofi Aventis.
The pragmatic Hestia criteria proved as safe as the more structured, points-based simplified Pulmonary Embolism Severity Index (sPESI) score for selection of patients with acute pulmonary embolism for outpatient care in the large, randomized HOME-PE trial presented at the virtual annual congress of the European Society of Cardiology.
“These results support outpatient management of acute pulmonary embolism patients using either the Hestia method or the sPESI score with the option for the physician-in-charge to override the decision. In hospitals organized for outpatient management, both triaging strategies enable more than a third of pulmonary embolism patients to be managed at home with a low rate of complications,” Pierre-Marie Roy, MD, said in presenting the HOME-PE findings.
The study clarifies a transatlantic controversy regarding how best to triage patients with acute pulmonary embolism (PE) for outpatient care. The answer? It’s basically a tie between the points-based sPESI score recommended in the current ESC guidelines (Eur Respir J. 2019 Oct 9;54[3]:1901647) and the Hestia method endorsed in the American College of Chest Physician guidelines (Chest. 2016 Feb;149[2]:315-52).
The sPESI is a validated tool that grants 1 point each for age over 80 years, background cardiopulmonary disease, a systolic blood pressure below 100 mm Hg, cancer, a heart rate of 110 bpm or more, and an oxygen saturation level below 90%. A patient needs a score of zero to be eligible for outpatient management. In contrast, the Hestia method relies upon 11 simple bedside criteria rather than a points system, explained Dr. Roy of University Hospital of Angers, France (J Thromb Haemost. 2011 Aug;9[8]:1500-7).
HOME-PE was a randomized, open-label, noninferiority trial conducted at 26 hospitals in France, Belgium, Switzerland, and the Netherlands. The study included 1,974 patients presenting to the emergency department with non–high-risk acute PE as defined by hemodynamic stability. About 39% of patients in the Hestia group were eligible for outpatient care on the basis of ‘no’ answers regarding all 11 criteria, while 48% of patients had an sPESI score of 0 and were thus initially considered appropriate for outpatient management.
However, the investigators recognized that no scoring system for acute PE is perfect, and that the judgment of a physician with extensive experience in managing this life-threatening condition counts for a lot. So they stipulated that a patient’s physician-in-charge could overrule a decision for early discharge. This happened 29% of the time in patients with a sPESI score of 0, as compared with a 3% overrule rate with the Hestia rule. The physician-in-charge also moved small numbers of patients who were Hestia or sPESI positive into the outpatient care group. As a result, a similar proportion of patients in both groups were discharged home within 24 hours for outpatient treatment: 38% of the total Hestia group and 37% in the sPESI arm.
Major adverse event rates were reassuringly low in both groups managed on an outpatient basis. The composite of recurrent venous thromboembolism, bleeding, or death within 30 days occurred in 1.3% of Hestia outpatients and 1.1% of sPESI outpatients. Among patients managed in the hospital, these rates were 5.6% in the Hestia group and 4.7% in the sPESI group.
Discussant Stavros V. Konstantinides, MD, who chaired the ESC guideline committee, asked rhetorically, “who’s happy with the HOME-PE trial? I think everybody.”
