There's a reason that women are often misdiagnosed after a heart attack. In women, heart disease is more likely to occur in the small blood vessels, not major arteries as is generally the case for men.

Heart attacks in patients considered low risk and otherwise healthy has long puzzled doctors. But now they may have identified a hidden culprit in women.

Heart disease research more frequently involves men. Yet a third of deaths among U.S. women are from cardiovascular disease, sparking recent interest in gender's role in heart disease.

At one time sudden cardiac death was viewed as rather random, but now new risk factors are regularly identified. One group that is at a higher risk is postmenopausal women with coronary artery disease.

New research from the University of Oxford, England, shows a mother's stroke can help predict her daughter's heart attack.

New research indicates middle-aged women could reduce their risk of cardiovascular disease by lowering their systolic blood pressure (the pressure when the heart contracts).
