If I don't smoke and my cholesterol is within normal limits, what impact does my family history of heart attack have on my risk?
Having a family history of a first-degree relative?your mother, father, or sibling?with a heart attack before age 55 for a man or 65 for a woman is a major risk factor for developing heart disease and stroke.
Keep in mind that low cholesterol levels may not be what they seem?low HDL, the ?protective? cholesterol, may keep your overall levels down, but that is not beneficial. Other factors such as diet, exercise, and smoking are also of significant importance to those with a family history of heart disease.
