What is All are true about hyperophic cardiomyopathy except and explain in detail?
Ref Harrison 19 th ed pg 1568 Biopsy is not needed to diagnose hyperophic cardiomyopathy but can be used to exclude infiltrative and metabolic diseases. Rigorous athletic training (athlete's hea) may cause intermediate degrees of physiologic hyperophy difficult to differentiate from mild hyperophic cardiomyopathy. Unlike hyper- trophic cardiomyopathy, hyperophy in the athlete's hea regresses with cessation of training, and is accompanied by supernormal exer- cise capacity (VO2max >50 mL/kg/min), mild ventricular dilation, and normal diastolic function.
