Women who go through menopause before age 46 are twice as likely to have a heart attack or stroke as women who hit menopause later, according to a new study.
“These are women who should keep in mind that they are at increased risk,” said Dr. Melissa Wellons, the lead author of the study from the University of Alabama at Birmingham.
The findings from a diverse group of U.S. women support results of earlier studies, which had focused on white women. Little was known about age at menopause and heart disease risk among women of other ethnicities.
Wellons and her colleagues collected health information through surveys of 2,509 women, including 331 Chinese, 641 black and 550 Hispanic women. Close to 700 of them, or 28 percent, had gone through menopause early, before age 46. (The average age when women in the U.S. stop having periods is 51.)Heart attack or stroke
That group included women who went through menopause naturally or had a hysterectomy, surgery to remove the uterus, which can cause early menopause.
None of the women had cardiovascular disease at the beginning of the study. Researchers tracked them for an average of five years to see who ended up having a heart attack or stroke.
They found 23 of the women who had gone through menopause early, and 27 who hadn’t, suffered a heart attack or cardiac arrest or died from heart disease, according to findings published in the journal Menopause.
That translates to 3.3 percent of women in the early menopause group and 1.5 percent of the other group.
Similarly, 18 women or 2.6 percent- of the early menopause group had a stroke during the study, compared to 19 (one percent) of women who hit menopause later. It’s not clear why early menopause might be linked to cardiovascular disease.
Wellons said estrogen could be related. Women’s bodies produce little estrogen after they go through menopause.
