New Insights and Recommendations for Athletes With Hypertrophic Cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) has long been considered to be a high-risk cardiac condition for which exercise was thought to increase the risk of sudden cardiac death (SCD). This was founded in part by initial autopsy studies reporting HCM to be a leading medical cause of SCD among young athletes. Most forms of competitive sport and exercise were therefore thought to increase the risk of SCD to a prohibitive level.

Masters athlete screening study (MASS): incidence of cardiovascular disease and major adverse cardiac events and efficacy of screening over five years.

Background: The efficacy of cardiovascular screening in Masters athletes (MAs) (≥35 y), and whether screening decreases their risk of major adverse cardiac events (MACEs) is unknown.

Purpose: To evaluate the effectiveness of yearly cardiovascular screening, and the incidence of cardiovascular disease (CVD) and MACE over five years.

Methods And Results: MAs (≥35 y) without previous history of CVD underwent yearly cardiovascular screening.

Sports-Related Sudden Cardiac Death Attributable to Myocarditis: A Systematic Review and Meta-analysis.

Background: The incidence of sports-related sudden cardiac death (SrSCD) attributable to myocarditis is unknown. With the known association between SARS-CoV-2 (COVID-19) and myocarditis, an understanding of pre-pandemic rates of SrSCD due to myocarditis will be important in assessing a change of risk in the future. The objective was to ascertain the incidence of SrSCD or aborted sudden cardiac death (SCD) attributable to myocarditis in the general population.
