One in 10 women ages 45 to 64 has some form of cardiovascular disease, according to statistics compiled this year by the American College of Obstetricians and Gynecologists.
* At about 500,000 deaths a year, cardiovascular disease is the No. 1 cause of death for women in the United States.
* Cardiovascular disease, including stroke (also called a "brain attack") and heart attack, claims more women than the number who die from the next 16 causes of death combined.
* Every year since 1984 it's killed more women than men.
* Many women are concerned about breast cancer. Although it takes the lives of one in 26 women, cardiovascular disease claims one in two.
