What are the causes of dilated cardiomyopathy?


Sometimes, the cause of a person’s dilated cardiomyopathy can’t be found out. About 1/3 of the patients with the disease get it due to heredity. One or both of their parents have it, so they have the disease in their genes.

Besides genetic factors, other conditions and substances can also lead to dilated cardiomyopathy. They are:

Coronary heart disease

High blood pressure


Thyroid disease

Heart attack

Viral hepatitis and HIV

Infections, especially viral infections that inflame the heart muscle

Alcohol abuse

Complications during the last month of pregnancy or within 5 months of birth

Certain toxins such as cobalt

Chemotherapy medicines and radiation therapy used to treat cancer
