FAQ - Is heart disease hereditary?

There is an increase in the risk of heart attack if a first-degree relative (parent or sibling) has had a heart attack or stroke. That is mainly seen when the relative has had a heart attack before the age of 45 if they are male, 55 if they are female. Obviously, you cannot change your family history, but a positive history should suggest the need to improve all the other risk factors like stopping smoking and decreasing cholesterol.
