Hypertrophic Cardiomyopathy

Outcomes improve when you participate in your own care.

Martha Gulati, MD, FACC, CardioSmart Editor-in-Chief

Did you know that your heart has four chambers? It’s true. If you have hypertrophic cardiomyopathy, your heart muscle gets thicker, making these chambers smaller. This may make it harder for your heart to pump blood.

This condition is inherited, meaning it is passed down in families. It is likely the result of problems with the genes that control the growth of your heart muscle. If you or your family member has been diagnosed with hypertrophic cardiomyopathy, it is important to remember you’re not alone.  It affects about 1 in every 500 adults and is the most common genetic heart disease. People of all ages, including children and teens, may develop hypertrophic cardiomyopathy, with younger people being more likely to have a severe form of the condition.

If you have hypertrophic cardiomyopathy, it is possible you will not show any symptoms. However, you may feel very tired or have a hard time catching your breath.  You may also feel pain in your chest or dizziness because your heart is not able to pump blood effectively throughout your body.  Hypertrophic cardiomyopathy can lead to conditions such as irregular heart rhythms or heart failure.

As with any heart condition, it is important to take good care of yourself and follow your doctor’s recommendations for exercise and medications. Use this condition center to learn more about hypertrophic cardiomyopathy. You can keep up with the latest research, find questions to ask your doctor, and get tips to help you feel your best.
