Statistics don't lie

One in 10 American women between the ages of 45 to 64 has some form of heart disease.
One in 4 women in the United States over age 65 has some form of heart disease.
A higher percentage of women than men age 50 and older have total blood cholesterol levels of 200 mg/dL or higher, a key risk factor for heart disease.
Women are more likely than men to die of heart attacks within a few weeks after the attack, in part because women have heart attacks later in life than men do.
Within 1 year after a heart attack, 38 percent of women will die (compared with 25 percent of men).
Within 6 years after a heart attack, 35 percent of women will have another one (compared with 18 percent of men), and 46 percent of women will experience heart failure (versus 22 percent of men).
