Cardiomyopathy literally means disease of the heart muscle or the myocardium. In this disease, the heart loses its ability to pump blood and beat at a normal rhythm. The condition tends to start off mild and then worsens fairly quickly. In the most severe cases, cardiomyopathy can lead to congestive heart failure. The main types of Cardiomyopathy are:

Dilated or 'enlarged' heart, the most common form of Cardiomyopathy occurs when the heart muscles become weak and cannot pump blood effectively. The weak muscles relax, and allow the chambers of the heart to expand. Most cases of dilated cardiomyopathy are a result of coronary artery disease, but about 30 percent of cases are genetic in origin. Dilated Cardiomyopathy occurs in 2 out of 100 people. It occurs most often in middle age, and it affects more men than women. However, this disease can occur in people of all ages, including children. Although dilated cardiomyopathy often occurs in people with no family history of the disease, about 30 percent of cases are thought to have genetic causes. Hypertrophic or 'thickened muscle'; In hypertrophic cardiomyopathy, the heart muscle cells become enlarged. In fact, the word "hypertrophy" literally means enlargement. This enlargement results in a thickening of the walls of the heart, which then prevents the heart from functioning properly. In hypertrophic cardiomyopathy, the heart muscle cells become enlarged. In fact, the word "hypertrophy" literally means enlargement. This enlargement results in a thickening of the walls of the heart, which then prevents the heart from functioning properly. Arrhythmogenic right ventricular, a more unusual form associated with arrhythmias; is a very rare cardiomyopathy that occurs in one out of every 5,000 people. In this disease, the muscle of the right ventricle is gradually replaced by a layer of fatty tissue. This fatty tissue causes major problems with the heart's rhythm. The most common result of this disease is cardiac sudden...
