Genetics can influence the risk for heart disease in many ways. Genes control every aspect of the cardiovascular system. From the strength of the blood vessels to the way cells in the heart communicate. A genetic variation (mutation) in a single gene can affect the likelihood of developing heart disease.
Genetic testing for inherited heart disease can identify the cause of a family’s heart disease. Testing can also help determine which specific relatives are at risk for developing it.
Person with an inherited cardiovascular condition may have few or no symptoms but still face significant risk of heart disease, including sudden cardiac arrest. Genetic testing can help save lives.
