Even though heart disease and stroke are the Number One killers of women, most of them remain unaware of this threat, a new survey shows.

Not only that, but healthcare providers also tend to focus on risk factors for heart disease and stroke with men, such as high blood pressure and cholesterol, than they do with women, the survey also found.

One in three women die from heart disease and stroke in the U.S. every year. Although heart disease and stroke death rates among men have dropped steadily over the last 25 years, women's have fallen at a much slower rate, the American Heart Association says.

A 2014 national survey of 1, 011 adult women found that only those who know another woman with heart disease were 25 percent more likely to be concerned about it for themselves and 19 percent more likely to bring up heart health with their doctors.

But the survey also found that only 27 percent of women could name a woman in their lives with heart disease and only 11 percent knew a woman who has died from heart disease.

Among those respondents age 25 to 49, about 23 percent said they knew a woman with heart disease, compared to 37 percent of women aged 50 to 60.

"We are stalled on women's awareness of heart disease, partly because women say they put off going to the doctor until they've lost a few pounds. This is clearly a gendered issue," said lead author C. Noel Bairey Merz, M.D., of the study, which was presented at the 2015 AHA Scientific Sessions in Orlando, Fla.
