WHI study finds no heart disease benefit, increased stroke risk with estrogen alone

The estrogen-alone study, part of the WHI, found that women taking this form of hormone therapy had an increased risk of stroke, with 44 cases per 10,000 women per year. However, it did not reduce the risk of coronary heart disease. The study involved 10,739 postmenopausal women and was stopped early due to these findings.
