Does detraining help differentiate physiological left ventricular hypertrophy from hypertrophic cardiomyopathy in an elite adolescent athlete?
An 8-week period of detraining can successfully differentiate physiological left ventricular hypertrophy from hypertrophic cardiomyopathy in elite athletes by resolving ECG and echocardiographic abnormalities.
The differentiation of physiological left ventricular hypertrophy (LVH) from hypertrophic cardiomyopathy (HCM) can prove challenging for even the most experienced cardiologists. The case is presented of a 17 year old elite swimmer who had electrocardiographic and echocardiographic features that were highly suggestive of HCM. However, indices of diastolic function were normal and cardiopulmonary exercise testing revealed high peak oxygen consumption in keeping with physiological LVH. To resolve the diagnostic dilemma, the patient underwent detraining for eight weeks, after which, there was complete resolution of the changes seen on electrocardiogram and echocardiogram, indicating physiological LVH rather than HCM.
Basavarajaiah et al. (Fri,) conducted a case report in Physiological left ventricular hypertrophy vs hypertrophic cardiomyopathy (n=1). Detraining was evaluated on Resolution of electrocardiogram and echocardiogram changes. Detraining for eight weeks resulted in complete resolution of electrocardiographic and echocardiographic changes, confirming physiological left ventricular hypertrophy rather than hypertrophic cardiomyopathy.
