Hypertrophic Cardiomyopathy

Home Treatment

Because of the risk of sudden death, it is important for people with hypertrophic cardiomyopathy to avoid too much strenuous activity and intense exercise. About 50% of sudden deaths in people with hypertrophic cardiomyopathy occur during or just after strenuous physical activity.¹ Talk to your doctor about what level of exercise and what kinds of activities are safe. Because dehydration can also worsen symptoms in people with hypertrophic cardiomyopathy, prolonged activity in hot weather is not recommended.

The following self-care recommendations are also important.

• Avoid drinking alcohol. Long-term overuse of alcohol appears to increase the risk of developing certain types of heart problems.
• Don't smoke. Tobacco use increases the risk of coronary heart disease, which can lead to a heart attack. For help quitting, see the topic Quitting Tobacco Use.
• Stay well hydrated (unless you have heart failure or another medical condition and need to limit your fluid intake).
• Weigh yourself daily. If fluid begins to build up rapidly, you will notice a sudden weight gain. Your doctor may tell you how much weight to watch for. But in general, call your doctor if you gain 3 lb (1.4 kg) or more in 2 to 3 days.

Follow your doctor's recommendations for regular exams to monitor your condition.

Because some people with hypertrophic cardiomyopathy may be at increased risk for sudden death, it is a good idea for family members to learn CPR (cardiopulmonary resuscitation).

For more information, see the topic Heart Failure.
