Cardiovascular Complications of COVID-19 in Athletes: A Systematic Review and Meta-analysis.

This systematic review and meta-analysis aimed to assess the prevalence of cardiovascular complications associated with coronavirus disease 2019 (COVID-19) infection in athletes. A comprehensive search was conducted across PubMed, Web of Science, Scopus, and the Virtual Health Library using the terms ("COVID-19" OR "SARS-CoV-2") AND ("athletes" OR "athlete") AND ("pericarditis" OR "myocarditis" OR "pericardial effusion" OR "cardiovascular" OR "cardiac"). Of 671 records, 20 studies met the inclusion criteria. The most commonly reported cardiovascular abnormality was pericardial effusion, with a pooled prevalence of 1.9% (95% CI 0.08-4.4), followed by myocarditis (1.5%; 95% CI 0.9-2.7), pericarditis (1.3%; 95% CI 0.8-2.1), and myopericarditis (0.9%; 95% CI 0.2-3.4). No cases of cardiovascular or all-cause mortality were reported among athletes with COVID-19. These findings suggest that cardiovascular complications are rare in athletic populations following COVID-19 infection, potentially reflecting the protective effect of a robust immune system and high baseline cardiovascular fitness.
