BOSTON (AP) -- Estrogen pills fail to ward off new strokes in older women who have already suffered them, a study finds.
Estrogen is rarely given solely to prevent strokes, though some earlier reports suggested that it might help do this. However, the latest study found no evidence that it does any good in those at high risk because of earlier strokes.
The hormone is used mostly to prevent brittle bones and ease hot flashes and other symptoms of menopause. It has also been prescribed to keep the heart healthy.
