Nclex 26 Review on Cardiomyopathy
– Cardiomyopathy is a disease that affects the myocardial structure in the heart,
and therefore impairing the cardiac function.
There are three main types of cardiomyopathy.
- DILATED CARDIOMYOPATHY- WITH THIS TYPE, THE VENTRICLES ARE DILATED WITH DESTRUCTION OF MYOCARDIAL FIBERS LIMITING CONTRACTILITY AND CAUSING SYSTOLIC DYSFUNCTION.
- HYPERTHROPHIC CARDIOMYOPATHY- MYOCARDIAL THICKENING OF THE VENTRICULAR WALL AND SEPTUM CAUSING A RIGID VENTRICLE AND DIASTOLIC DYSFUNCTION.
- RESTRICTIVE CARDIOMYOPATHY- THE VENTRICLES BECOME RIGID WITH FIBROTIC TISSUE, CAUSING SYSTOLIC DYSFUNCTION.
