There’s no link between menopause and increased risk of death from heart disease, says a study that challenges a long-held medical belief that the rate of cardiovascular death in women spikes after menopause. Aging alone, not the hormonal impact of menopause, explains the increasing number of deaths among older women, according to the Johns Hopkins researchers. The new findings could affect how heart health is assessed in premenopausal women, who were previously believed to have a low risk of death from heart attack, the authors pointed out in the study published in the Sept. 6 issue of the BMJ.
