Risk factorsBy Mayo Clinic Staff
There are a number of risk factors that can increase your risk of cardiomyopathy, including:
March 17, 2015
- Family history. People with a family history of cardiomyopathy, heart failure and sudden cardiac arrest are more likely to develop cardiomyopathy than are those without a family history of heart problems.
- High blood pressure. People who have high blood pressure over a long period of time are at higher risk of cardiomyopathy.
- Conditions that affect the heart. People who have had a heart attack, coronary artery disease or viral infections that affected the heart are at higher risk of cardiomyopathy.
- Obesity. Excess weight makes the heart work harder, which may increase the risk of cardiomyopathy and heart failure.
- Alcoholism. People who abuse alcohol can damage their hearts, and cardiomyopathy can be a consequence. The risk increases significantly after more than five years of drinking seven to eight drinks daily.
- Illicit drug use. Drugs, such as cocaine, amphetamines and anabolic steroids, may increase the risk of cardiomyopathy.
- Cancer treatments. While necessary to treat cancer, many cancer treatments can damage some healthy cells too. Certain chemotherapy drugs and radiation therapy can increase the risk of cardiomyopathy.
- Diabetes. Having diabetes ups the risk of cardiomyopathy, heart failure and other heart problems.
- Thyroid disorders. Having an under- or overactive thyroid gland can increase your risk of cardiomyopathy.
- Hemochromatosis. This disorder causes the body to store excess iron, and it has been linked to an increased risk of dilated cardiomyopathy.
- Diseases that affect the heart. Other diseases, such as a disorder that causes the buildup of abnormal proteins (amyloidosis), a disease that causes inflammation and can cause lumps of cells to grow in the heart and other organs (sarcoidosis), or connective tissue disorders can increase your risk of cardiomyopathy.
