For decades, doctors have relied on the undisputed champion of heart disease risk assessment: the Framingham Risk Score. It emerged from a massive study of heart disease risk factors in more than 5,000 men and women and pointed out advanced age, being male, smoking, having diabetes, high total cholesterol, low levels of good cholesterol and high blood pressure.
