New results from a substudy of the Women's Health Initiative (WHI) Estrogen-Alone Trial show that younger postmenopausal women who take estrogen-alone hormone therapy have significantly less buildup of calcium plaque in their arteries compared to their peers who did not take hormone therapy. Coronary artery calcium is considered a marker for future risk of coronary artery disease.
Results of the WHI Coronary Artery Calcium Study are published in the June 21, 2007, issue of the New England Journal of Medicine. The WHI is sponsored by the National Heart, Lung, and Blood Institute of the National Institutes of Health.
