The best way to prevent cardiomyopathy is to prevent the diseases that cause it.
Know your risk factors for coronary artery disease. Modify those risks early in life.
You can reduce your risk for coronary artery disease by:
Keeping blood pressure normal. Eat a diet rich in vegetables and fruits. Take medication as needed.
Drinking no more than two alcoholic beverages per day. Do not drink alcohol at all if you are at high risk of dilated cardiomyopathy.
If you have any family members with inherited cardiomyopathy, contact your doctor for an evaluation.
