The highest incidence of SCD in young athletes is among those participating in sports like basketball, football, track, and soccer.[2] Triggers such as extreme physical exertion coupled with a substrate like underlying structural heart disease constitutes the pathologic basis of SCD in athletes.[1,3] An age cutoff of 35 years delineates younger from older athletes.[4] Hypertrophic cardiomyopathy (HCM) is reportedly the leading cause of sudden cardiac death in the younger age while atherosclerotic coronary artery disease predominate the older age group.[5,6]

True, but I will say that in all of my years following sports, I have never seen or heard of so many deaths in highly functioning young athletes. The increase in deaths is concerning. Maybe communication is better, maybe more people are involved in competitive athleticism, maybe drug use in athletes is higher than in the past...but this is strange....something is happening...may not be explained by the same old reasons
