First
strokes are generally more severe and disabling in women than men, according to
a study reported in the June 13 rapid access issue of Stroke. In
the United States, stroke is the third-leading cause of death. Women accounted
for 61.4 percent of U.S. stroke deaths in the year 2000, according to the American
Heart Association. Women
in the study had higher rates of an irregular heart rhythm called atrial fibrillation
that can ultimately lead to strokes if not treated with blood-thinning anticoagulant
drugs.
Lead researcher
Dr. Jaume Roquer, of the Servei de Neurología at the Hospital
del Mar in Barcelona, Spain, said the findings show the need to
increase use of preventive anticoagulation treatment in women
since their frequency of atrial fibrillation is greater than men.
He added
that better control of hypertension should also be another important
therapeutic goal to decrease the incidence of stroke in women.
Roquer and
colleagues studied 1,581 first stroke patients. The women were
older than the men -- 75 years old versus 69 years old. The predominant
stroke risk factors in women were hypertension and atrial fibrillation
in women.
In men, peripheral
artery disease and alcohol overuse were more likely related to
stroke. No gender differences were found for diabetes, past history
of ischemic heart disease or high cholesterol.
Aphasia --
the inability to use or comprehend words -- was present in 29
percent of women compared with 22 percent of men. About 17 percent
of women had visual impairments compared with 14 percent of men.
Dysphagia -- difficulty chewing or swallowing -- was found in
about 20 percent of women and 14 percent of men.
The health
condition of women at admission was worse than men, in-hospital
medical complications were more frequent in women, and the length
of hospital stay was longer. The death rate was higher in women.
The
researchers suggest that the reason that more women than men are incapacitated
after a stroke might be due to their older age, the greater stroke severity and
higher rate of in-hospital medical complications. Other
