Doctors say reducing deaths from heart disease will require not only changes in the way people live. It will also require changes in public policy, and better public knowledge about differences in heart disease between men and women.
Two conditions,coronary artery disease and microvascular disease, can both reduce blood flow to the heart. Experts at Brigham and Women"s Hospital in Boston say heart disease in women is more likely to be caused by microvascular disease.
Reducing risk means not smoking. It means controlling or avoiding diabetes. It also means keeping a healthy weight and eating healthy foods. And it means exercising at least 30 minutes on most days and managing or reducing stress.
Dr Dariush Mozaffarian at the Harvard School of Public Health also has other advice about reducing the risk of heart attacks. He says people should eat more fish, whole grains, vegetables,vegetable oils and nuts, and reduce the amount of salt and trans fats in their diets. Trans fats can increase the risk of heart disease.
