Key result
Exaggerated myocardial hypertrophy in response to sports training, rather than hypertrophic cardiomyopathy, may be the underlying cause of sudden unexpected cardiac death in young athletes.
This review challenges the conventional paradigm that hypertrophic cardiomyopathy is the principal cause of sudden cardiac death in young athletes, proposing instead that extreme physiological hypertrophy from training may lead to fatal electrical instability.

Hypothesis-generating for training-induced hypertrophy as SCD cause; leaves open whether screening paradigms should shift from HCM focus.
Thomas Rowland (2009) conducted a review in Sudden unexpected cardiac death in young athletes. Exaggerated myocardial hypertrophy in response to sports training was evaluated on Sudden unexpected cardiac death. Exaggerated myocardial hypertrophy in response to sports training, rather than hypertrophic cardiomyopathy, may be the underlying cause of sudden unexpected cardiac death in young athletes.
