Beyond recovery: long-term cardiovascular risks after severe COVID-19 requiring intensive care
Main finding · ASCVDResult — go to the resultSubdistribution hazard ratio 1.42 95% CI 1.26–1.60Authors' conclusion
Among ICU-treated survivors of severe COVID-19, the risk of ASCVD, heart failure, atrial fibrillation, and all-cause mortality was increased during three years of follow-up compared with the matched population-based controls, with associations strongest during the first year of follow-up [period-specific estimates are provided in the Supplementary].
