Many American women believe breast cancer is the biggest threat to their health. But more than ten times as many women die of diseases of the heart and blood vessels. (30) The American Heart Association has new guidelines to help prevent heart attacks. For example, the guidelines urge women not to use hormone replacement therapy as a way to protect the heart. The guidelines also urge women to know their risk of heart attack or heart disease. They suggest that a woman talk to her doctor about this beginning as young as the age of twenty.
    (31) The heart association Web site has information that can help people measure their level of risk. Users answer some questions. They enter their age and whether or not they smoke etc. A total score below ten percent is considered low risk. This means that a woman has less than a ten percent chance of a heart attack in the next ten years. The next level of ten to twenty percent is considered intermediate risk. More than twenty percent is high risk. (32) The heart association says those at high risk should ask their doctor for medicine. Women are also urged to ask for treatment if their blood pressure is one-hundred-forty over ninety or higher. The guidelines say women at intermediate or high risk should consider taking an aspirin each day. Aspirin may reduce the risk of a heart attack.
