Hypertrophic cardiomyopathy (HCM) is a condition in which the heart becomes thickened without an obvious cause. [12] Calcium channel blockers are generally contraindicated due to their negative inotropic effect, particularly in cardiomyopathy caused by amyloidosis. 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. Beta-blockers are drugs that improve the heart's ability to relax. Hypertrophic cardiomyopathy is an autosomal dominant. This results in the heart being less able to pump blood effectively and also may cause electrical conduction problems..

However, the exact reason behind the occurrence is unknown. Hypertrophic cardiomyopathy (HCM) is a genetically determined heart muscle disease most often (60 to 70 percent) caused by mutations in one of several sarcomere genes which encode components of the contractile apparatus. Hypertrophic cardiomyopathy — The muscular heart wall thickens abnormally. It is not uncommon for severe pulmonary edema to follow a bout of protracted tachycardia ... the thiazide diuretics are relatively contraindicated. Hypertrophic cardiomyopathy (HCM) is a complex cardiovascular disorder characterized by unexplained non dilated left ventricular (LV) thickening in the absence of other cardiac or systemic diseases justifying the degree of hypertrophy observed [].The morphological, histological, and clinical phenotypes of HCM reflect complex … As a result, the heart muscle cannot relax fully. Elderly patients with hypertrophic cardiomyopathy: a subset with distinctive left ventricular morphology and progressive clinical course late in life. Hypertrophic cardiomyopathy is predominantly a disease of left ventricular outflow tract obstruction. Preparations that reduce preload (for example, nitrates, diuretics, ACE inhibitors, APA II), reduce the size of the heart chambers and aggravate the symptoms of hypertrophic cardiomyopathy. Circulation. Salt-restriction, diuretics, angiotensin-converting enzyme inhibitors, and anticoagulation may be indicated for managing restrictive cardiomyopathy. 2006; 114: 2232–2239. 2008 May 27.

The parts of the heart most commonly affected are the interventricular septum and the ventricles.
