Overview

obesity cardiomyopathy is defined as congestive heart failure due to structural and hemodynamic changes because of obesity.

increased total blood volume and cardiac output because of the high metabolic activity of excessive fat in long standing obesity

may lead to left ventricular dilation, increased left ventricular wall stress, compensatory (eccentric) left ventricular hypertrophy, and left ventricular diastolic dysfunction.inadequate hypertrophy might tend to Left ventricular systolic dysfunction may occur if wall stress remains high .sleep apnea/ obesity hypoventilation syndrome might tend topulmonary hypertension and subsequent Right ventricular structure and function
