Women may have a different type of heart disease
Part of the reason heart attack symptoms can present differently in women is because there’s a difference in plaque and blockage patterns between men and women, according to cardiologist C. Noel Bairey Merz, MD, director of the Women’s Heart Center at the Cedars-Sinai Heart Institute. On the center’s website, Dr. Bairey Merz explains that women’s heart disease should be called ischemic heart disease, which indicates a lack of blood flow and oxygen to the heart. (The kind of heart disease that primarily affects men should remain coronary artery disease, which indicates plaque build-up in the arteries near the heart). “Women with ischemic heart disease generally have major arteries that are clear of plaque, but the smaller coronary blood vessels cease to constrict and dilate properly, creating the lack of blood flow and oxygen to the heart,” according to the site. Women can have normal angiograms and stress tests even if they have ischemic heart disease; doctors should pay attention to symptoms like chest pain and shortness of breath instead of just looking at test results, Dr. Bairey Merz says.
Female heart attack patients take longer to get to the hospital
Seventy percent of women having a heart attack took longer than an hour to get to a hospital, according to a 2015 European study of 7,400 heart attack patients. Only 30 percent of men with heart attack symptoms took as long, HealthDay reported. A main reason for the delay: Women took longer to call for help than men did. “Our findings should set off an alarm for women, who may not understand their personal risk of heart disease and may take more time to realize they are having a heart attack and need urgent medical help,” study author Raffaele Bugiardini, a professor of cardiology at the University of Bologna in Italy, said in a press release.
Everyday stress can affect women’s hearts more
In a recent Duke University study, men and women with heart disease performed stressful tasks while researchers studied their heart functions. Fifty-seven percent of the women experienced reduced blood flow to their hearts during stressful times compared with 41 percent of the men. Blood platelet clumping, which can lead to a heart attack, was also more prevalent in stressed women than in stressed men, a finding researchers say could help tailor blood-thinning treatment for more effective use in women.
