Women who go into menopause when they are younger than 40 have a greater risk for future heart problems, according to a new study published in the European Heart Journal. Korean researchers collected data on over 1.4 million females. They found that the risk for heart issues increased for women who entered menopause earlier in life compared to those who went into menopause after age 50. Specifically, they observed that the risk of heart failure was 39 percent higher among women who experienced menopause before age 40. The risk of atrial fibrillation, or an irregular heart rhythm, was 11 percent higher. About 1 in 100 women go through menopause before they hit their forties. Knowing these heart risks hopefully will encourage these women to follow heart-healthy lifestyle habits, like exercising on a regular basis and quitting smoking.
