Clinical Description

HCM is a primary myocardial disease defined by the World Health Organization (WHO) as ''left and/or right ventricular hypertrophy, which is usually asymmetric and involves the interventricular septum.''[1] Histological features include myocyte hypertrophy and disarray, and increased interstitial fibrosis.

The diagnosis of HCM is made by clinical examination, electrocardiogram, and transthoracic echocardiogra-phy for the detection of unexplained left ventricular hypertrophy (LVH) greater than 13 mm in the absence of another cardiac or systemic disease. LVH is typically asymmetric with a diffuse or segmental (subaortic, midventricular, or apical) pattern and is usually associated with a hyperdynamic left ventricle (LV).[2] The differentiation of HCM from physiologically mild LVH, such as in athletic hearts, is crucial. Distinction in a nonobstruc-tive or obstructive form of HCM is based on the presence or absence of a systolic outflow tract gradient under resting and/or provoking conditions. Symptoms in HCM are complex.[3] Exertional dyspnea, typical or atypical angina, and loss or impairment of consciousness are

Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
