What heart conditions can run in families because of genetics?

If I already have a heart problem and see a doctor for it, why should I consider speaking to a genetic expert?

I’m not sure I want to learn about my genetic risk for heart problems. How could this help improve my or my family’s health?

How do I figure out which genetic test for heart problems is the best option for me?

Does an abnormal genetic test result mean I’m definitely going to have heart problems?
