Cardiovascular disease is women's top killer. Fifty-seven percent of U.S. women are aware of heart disease as the leading cause of death in females, an increase from previous years, according to the American Heart Association (AHA). However, awareness among African-Americans and Hispanic women was lower than among Caucasian women and has not changed significantly over time. Risk factors for heart disease can be divided into those that suggest a major risk and those that lead to an increased risk. Major risk factors are high blood pressure, high blood cholesterol, diabetes, obesity or being overweight, smoking, physical inactivity, heredity, and age. Factors that could lead to an increased risk include stress and excessive alcohol consumption—for women, that means more than one drink a day.
