Called the Silent killer, the numbers are staggering for heart disease in women. Cardiovascular disease, which includes heart disease, hypertension and stroke, is the number one killer of women, according to the American Heart Association. It kills half a million American women each year. That figure exceeds the next seven causes of death combined. Moreover, women are 15% more likely than men to die of a heart attack. And they are twice as likely to have a second heart attack in the six years following the first. Yet in a 2000 national heart association survey, only 34% of women correctly identified heart disease as a leading cause of death.
