Genetic testing can determine if you or your children are at risk of hypertrophic cardiomyopathy, an inherited disease that can lead to sudden cardiac death and other severe heart problems.
Here are some important things to know about Hypertrophic Cardiomyopathy (HCM):
- HCM is the most common cause of sudden cardiac death in young adults, including trained athletes.*
- HCM is the most common inherited cardiac disease, affecting 1 in 500 people.
- About half of all children of affected parents will inherit the condition.
- HCM is caused by a genetic mutation.
- Finding out that you or a family member has HCM can help you and your doctor find the most appropriate treatment and determine the risk of sudden cardiac death. In high-risk patients, aggressive treatment including the implantation of a device called a defibrillator may be indicated in order to help prevent sudden cardiac death.**
If you believe genetic testing could help you or your family members, please follow these simple steps:
- Make an appointment with your doctor (either your primary care physician, internist, family doctor, or cardiologist, if you have one) to discuss if genetic testing is right for you and your family.
