Fact of the day - Athlete's heart


Athlete's heart - physiologic eccenteric hypertrophy (cardiac remodeling) - changes include resting bradycardia, higher cardiac output with exercise, dilatation of LV cavity size with hypertrophy of myocytes compared to normal heart.

vs pathologic hypertrophy in case of systolic heart failure, aortic/mitral regurgitation, dilated cardiomyopathy(DCM) (volume overload conditions).

LV systolic ejection fraction is normal - low-normal in athletes.

(vs HCM- high, DCM- low)

HCM is a common cause of death in athletes, especially those with family history.

That's all
