Ageing, not menopause, ups heart disease risk in women



Posted On: Sept. 7, 2011

London, Sept 6 (ANI): Ageing, not hormonal impact of menopause, increases the risk of cardiovascular death for women, a new study led by an Indian-origin scientist has found.

The findings could have implications for how heart health is assessed in pre-menopausal women, who were previously believed to be at negligible risk of death from heart attack.

"Our data show there is no big shift toward higher fatal heart attack rates after menopause," says Dhananjay Vaidya, Ph.D., an assistant professor of medicine at the Johns Hopkins University School of Medicine and the study's leader.

"What we believe is going on is that the cells of the heart and arteries are aging like every other tissue in the body, and that is why we see more and more heart attacks every year as women age.

"Aging itself is an adequate explanation and the arrival of menopause with its altered hormonal impact does not seem to play a role," he added.

To reach its conclusions, Vaidya's team analyzed mortality statistics for people born in England, Wales and the United States between 1916 and 1945. They followed similar groups of people as they aged and found that, at the time of menopause in each cohort, there were no increases in female mortality rates above and beyond the steady curve that is expected from aging, he says.

The study has been published in BMJ, the British medical journal. (ANI)
