The next widespread type includes a dilated one. Such cardiomyopathy occurs while the lower chambers of the heart, also known as the ventricles, get larger and weaker. The left ventricle is the first place to be damaged. Sooner or later, the issue spreads over to the right side. The attacked chambers cannot pump blood the way they should. Patients feel their primary muscle functioning in a wrong manner. Many patients face such outcomes as heart failure, irregular rate, and blood clots.
