Cardiomyopathy must be differentiated from athlete heart (which is often confused with HCM on echocardiography), hypertrophy due to hypertension or aortic stenosis; as these have common clinical features, including thickened myocardium on imaging and high QRS voltage on EKGs. On the basis increased LV to aortic gradient, hypertrophic cardiomyopathy must be differentiated from sever volume depletion, subaortic stenosis, and valvular aortic stenosis.
