Why the study?
Sudden cardiac deaths in young elite athletes have been remarkable, and screening for HCM is not mandatory. The study tested whether echocardiography-derived variables distinguish HCM from other variants of LV hypertrophy.
Does echocardiography accurately distinguish hypertrophic cardiomyopathy from physiological athlete's heart and hypertensive left ventricular hypertrophy?
Does echocardiography accurately distinguish hypertrophic cardiomyopathy from physiological athlete's heart and hypertensive left ventricular hypertrophy?
Echocardiographic parameters including global longitudinal strain, LV mass index, LA volume index, and septal TDI E/e' ratio can accurately distinguish hypertrophic cardiomyopathy from physiological athlete's heart and hypertensive LVH.

These cutoffs may aid HCM differentiation from athlete's heart; leaves open prospective validation before routine use.
