Certain genes can pass on risk factors such as high blood pressure or high cholesterol. Shared environments can also be passed on to you from the previous generation in your family.

Why is it important to know your family’s history of cardiovascular disease?

A family health history can identify people with a higher-than-usual chance of having common disorders, such as heart disease, high blood pressure, stroke, certain cancers, and type 2 diabetes.
