Women had more than cardboard heart cutouts on their minds yesterday at the fifth annual Women’s Heart Health Fair, an event to promote heart health and alert women to the dangers of heart disease.

Sister to Sister, a nonprofit organization that screens and educates women with its heart health message, hosted the fair at the Prudential Center with 31 exhibitors ranging from the American Heart Association and the Boston University School of Public Health to Pampered Chef and Cabot Creamery.

Though both men and women are equally at risk for heart disease, it kills more women than the next five most frequent causes of death for women combined, said AHA representative Lisa Antzelevitch.

“Most people think of heart disease as an ‘old man’s disease’ and aren’t particularly aware of it, when in reality, cardiovascular disease kills one in 2.6 women,” she said. “Women take greater note to breast cancer, which only kills one in 30 women.”

Sixty-four percent of women who die suddenly of coronary heart disease have no previous symptoms of the disease, according to AHA statistics. AHA representative Jen Natoli said making women aware of the symptoms can aid earlier diagnosis.

“Symptoms tend to be more flu-like than what you would normally think of for patients with heart disease or a heart attack,” she said. “It’s not unlikely for physicians to even misdiagnose women.”

The fair included free heart screenings for women and body-mass index, blood pressure and cholesterol measuring opportunities. Presentations addressed lifestyle issues that contribute to a healthy heart such as proper nutrition, fitness and exercise.

Sister to Sister Boston campaign manager John Cox said the screenings done at the fair yesterday would be analyzed by professionals at Brigham and Women’s Hospital and the results would be shared with participants. He said the organization is planning to expand the program beyond the annual event in order to offer free screenings year round.

Attendees said they learned more about keeping a healthy heart from the day’s exhibits.

Harvard University student and teaching assistant Lena Brown said she is interested in heart health because her father died from a heart attack.

“I’ve learned a little today . . . about foods and what is good fat,” she said. “Sometimes you might avoid a food because you think it’s bad, when really it’s not at all and can be beneficial for you.”
