Women who didn't have metabolic syndrome beforehand showed no increased risk. The study was published this month online in Menopause, the journal of the North American Menopause Society.
"Our findings emphasize the importance of assessing cardiovascular disease risk status when hormone therapy is considered for relief of menopausal symptoms," wrote the WHI investigators who authored the study.
Metabolic syndrome is a group of risk factors that occur together and increase the risk of heart disease, stroke, and diabetes. They include a large waistline, high blood pressure, high blood glucose or diabetes, high triglycerides, or low HDL—the "good cholesterol." Obesity is the key feature, which predisposes women to the others.
In this analysis, a woman was considered to have metabolic syndrome if she had three of any of the five metabolic syndrome features; 269 women met the criteria when they started the trial and were compared with 695 women who did not have metabolic syndrome.
The women who did not have metabolic syndrome showed no increased risk of heart disease, whether they took hormones or not. But the risk of a heart attack or dying of heart disease was more than double for women who had metabolic syndrome and took hormones (either combined estrogen-progestogen or estrogen alone if they had undergone hysterectomy) compared with women who had metabolic syndrome and did not take hormones. Women with metabolic syndrome who took estrogen alone had a smaller increase in risk, but they were still at significantly higher risk than women with metabolic syndrome who did not take hormones.
In the WHI, women took oral formulations of hormone therapy, which were common at the time. Today, smaller doses and other forms, such skin patches or gels, are being used. In addition, women in the WHI were older (average age 66 in this analysis) than the age women usually start hormone therapy for menopause symptoms, such as hot flashes and night sweats. Newer formulations and earlier use of hormone therapy may be safer, but more study needs to be done to find out if having metabolic syndrome makes a difference with these types of hormone therapy.
The study will be published in the March 2013 print edition of Menopause.
Founded in 1989, The North American Menopause Society (NAMS) is North America's leading nonprofit organization dedicated to promoting the health and quality of life of all women during midlife and beyond through an understanding of menopause and healthy aging. Its multidisciplinary membership of 2,000 leaders in the field—including clinical and basic science experts from medicine, nursing, sociology, psychology, nutrition, anthropology, epidemiology, pharmacy, and education—makes NAMS uniquely qualified to serve as the definitive resource for health professionals and the public for accurate, unbiased information about menopause and healthy aging.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
