Although influenza and SARS-CoV-2 have long been associated with excess risk for cardiovascular events (CVE) such as myocardial infarction (MI) and stroke, less is known about the effects of respiratory syncytial virus (RSV) infection on CVE risk. In a retrospective study of adults admitted for RSV at two hospitals in upstate New York, investigators assessed CVE incidence during the 6 months before hospitalization (pre-RSV), the first 28 days after admission (high-risk RSV), and 29 days to 6 months after admission (late-risk RSV).
Among 471 patients (mean age, 67), 37% experienced CVEs during the high-risk RSV period (mostly within in the first 7 days). The most common CVEs were congestive heart failure (CHF; 25%) and atrial fibrillation (AF…
