Study: Women Need Clot-Busting Therapy After Stroke
ST. PAUL, Minn. -
New research shows women who don鈥檛 receive a clot-busting drug after a fare worse than men who are not treated. The study is published in the March 2, 2010, print issue of the medical journal of the . 鈥淲omen need to be treated for stroke as soon as possible,鈥 said study author Michael D. Hill, MD, MSc, FRCPC, with the University of Calgary in Alberta, Canada. 鈥淲e found that women who weren鈥檛 treated had a worse quality of life after stroke than men. However, the good news is that women who were treated responded just as well as men to the treatment.鈥 For the study, scientists examined information from a stroke database on 2,113 people who had experienced a stroke. Of those, 232 were treated with the clot-busting drug known as tissue plasminogen activator (tPA) and 44 percent were women. Men and women were separately placed in groups based on whether they received tPA within three hours after their stroke. After six months, the people were interviewed by phone about their ability to function and quality of life. The study found that women who did not receive the clot-busting drug were 12 percent less likely than men to have a good outcome six months later, or 58 percent of the women compared to 70 percent of men. However, women who were treated with these medications fared about the same as men who took the clot-buster drug. 鈥淭here could be many reasons why women who weren鈥檛 treated with the clot-busting drug fared worse than men, including biological reasons,鈥 said Hill. 鈥淥ne social reason may be that more than 30 percent of women were widowed compared to seven percent of men at the time of stroke, and therefore did not have a spouse who could act as a caregiver. Also, post-stroke depression is more common in women than in men, which slows down recovery.鈥 The study was supported by the Canadian Stroke Network, one of Canada鈥檚 Networks of Centers of Excellence program, and the Ontario Ministry of Health and Long-Term Care.
