Question
Is psychological, social, and economic stress associated with coronavirus disease 2019 (COVID-19) associated with the incidence of stress cardiomyopathy?
Findings
This cohort study included 1914 patients with acute coronary syndrome to compare patients presenting during the COVID-19 pandemic with patients presenting across 4 timelines prior to the pandemic and found a significantly increased incidence of 7.8% of stress cardiomyopathy during the COVID-19 pandemic, compared with prepandemic incidences that ranged from 1.5% to 1.8%.
Meaning
These findings suggest that psychological, social, and economic stress related to the COVID-19 pandemic was associated with an increased incidence of stress cardiomyopathy.
Background-Postoperative atrial fibrillation (AF) is a common complication of cardiac surgery and has been associated with increased incidence of other complications and increased hospital length of stay (LOS). Prevention of AF is a reasonable clinical goal, and, consequently, many randomized trials have evaluated the effectiveness of pharmacological and nonpharmacological interventions for prevention of AF. To better understand the role of various prophylactic therapies against postoperative AF, a systematic review of evidence from randomized trials was performed. Methods and Results-Fifty-two randomized trials (controlled by placebo or routine treatment) of -blockers, sotalol, amiodarone, or pacing were identified by systematic literature search.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
