"We know that since the [campaign] began seven years ago, millions of women have learned that heart disease is the No. 1 killer -- a new survey shows that 65 percent of women are aware of this fact," Nabel said. "But about one-third of women still underestimate their own personal risk of getting heart disease, and if you underestimate your risk, this can have serious consequences."
A few simple steps can minimize heart risk factors, helping to prevent "silent killers" such as high blood pressure and high cholesterol.
"The good news is women have the tremendous power to reduce their risk of getting heart disease," Gunn reminded the crowd. "By doing four things -- eating right, being physically active, not smoking, and having a good body weight -- women can lower their risk of getting heart disease by as much as 82 percent. That's a staggering percentage."
