4 The term Cardiomyopathy is purely descriptive, meaning Heart Muscle Disease “a heterogeneous group of diseases of the myocardium associated with mechanical &/or electrical dysfunction. It exhibit inappropriate ventricular hypertrophy or dilatation and are due to a variety of causes that frequently are genetic. Heart’s pumping ability ( left ventricle) becomes less forceful and become enlarge. It leads to death or progressive heart failure- related disability.” AHA 2010 1/15/2018
1/15/2018 6 Dilated • Left ventricle begins to dilate (stretch and become thinner) • As a result heart doesn’t contract normally and can’t pump blood very well. Hypertrophic • Heart muscle enlarge without any cause; ventricle to become thick. • Thickening may block blood flow out of the ventricle (workload) Restrictive (rare) • Deposition of substance, cause ventricle become stiff/rigid • Cant relax normally and fill with blood • Later ventricle do not pump as well and heart muscle weakens.
