GUIDE: Genetic Testing in Inherited Cardiovascular Conditions – Why is it important?

28.11.2018

Inherited cardiovascular conditions affect approximately 1 in 200 people worldwide. They are an important cause of sudden cardiac death in otherwise young, healthy individuals. Genetic testing may directly affect a patient’s medical management and may be the only way to identify their family members who are at increased risk of sudden death.

When should I consider genetic testing for my patient?

Patients with a personal or family history of one or more of the following may benefit from genetic testing:

  • Electrocardiographic (ECG) or imaging findings suggestive of or consistent with an inherited cardiovascular condition (ex. Unexplained prolonged QT interval, unexplained left ventricular hypertrophy)
  • Unexplained cardiac arrest and/or sudden death at a young age
  • Unexplained syncope and/or seizures
  • Unexplained elevated cholesterol and/or history of premature cardiovascular disease
  • Aortic dissection/aneurysm at a young age

Genetic testing is recommended in published guidelines and position statements by multiple international societies*.
