Cardiomyopathy - dilated

There are many causes of dilated cardiomyopathy. They may include nutritional deficiencies, valvular heart disease, anemia, stress, viral infections (rare), alcoholism (alcoholic cardiomyopathy), and coronary artery disease.

Dilated cardiomyopathy occurs in an estimated 2 out of 100 people. It can affect anyone of any age, although it is most common in adult men.

Risk factors include obesity, cocaine use, a personal or family history of cardiac disorders (such as myocarditis), and alcoholism.
