But according to the American Heart Association, cardiovascular disease is the leading killer of women
over age 25. It kills nearly twice as many women
in the United States than all types of
cancer, including breast cancer. Only 13 percent of women think heart disease is a threat to their health.
The misleading notion that heart disease is not a real problem for women can be blamed in part on medical research. For a very long time, heart disease studies have focused primarily on men.
