Understanding Cardiomyopathy and Genetic Testing
Cardiomyopathy is a serious heart problem and one of the main causes of heart failure and sudden heart-related death. Many people don’t know that up to half of all cases are genetic—meaning the condition can be passed down through families and affect several generations.
Genetic testing can help find out what caused your cardiomyopathy, guide your doctor in choosing the right treatment, and give your family important information that could even save lives.
Doctors and medical experts recommend by current medical guidelines:
Genetic testing for people with non-ischemic cardiomyopathy
➤ where it can help find the cause or guide treatment.
Genetic testing for close family members
➤ if a genetic cause is found, to help find the condition early and reduce the risk of serious problems.
Even with these recommendations, studies show that fewer than 2% of people with cardiomyopathy have had genetic testing—leaving many families without the answers they need.
To help close this gap, the Genetic Cardiomyopathy Awareness Consortium is helping connect patients with several genetic testing companies that offer testing to cardiomyopathy patients and their family members. See below for testing options.
What About Family Members?
Adult First-Degree relatives where a family member has tested positive for genetic cardiomyopathy —- close relatives, especially parents, siblings, and children, may also carry the same variant and should be tested.

Testing Options
Below are several testing options where you may order genetic testing or a family member may order genetic testing once a relative with cardiomyopathy has completed initial testing and has a positive test result.
Note: If you have already been tested for cardiomyopathy, you must be retested by one of these providers below to qualify for free family testing.
