Cardiomyopathy is a disease of the myocardium or heart muscle that causes cardiomegaly. 2 Even in the acute setting, AF can deteriorate heart failure or result in cardiogenic shock in patients with HCM, due to loss of atrial contraction and worsening of left ventricular outflow tract (LVOT) obstruction. Vasodilators increase the gradient of the outflow tract and cause reflex tachycardia, which subsequently worsens the diastolic function of the ventricle. Diuretics exert their action by reducing volume or preload. If your doctor thinks that you have HCM, you may be offered a genetic test to identify a faulty gene that may be causing your condition.
