(HealthDay News) – Women with acute ischemic stroke are less likely than men to arrive at the hospital within four hours and are less likely to receive thrombolytic treatment, according to research published online July 25 in Stroke.

Inger de Ridder, MD, from Erasmus University in Rotterdam, Netherlands, and colleagues analyzed data from 5,515 patients participating in the Promoting Acute Thrombolysis for Ischaemic Stroke study.

The researchers found that women were an average of four years older than men, and the median National Institutes of Health Stroke Scale score was higher in women than men (6 vs. 5). Intravenous alteplase was used in fewer women than men (11% vs. 14%; adjusted odds ratio, 0.8; 95% confidence interval, 0.7–1.0). Fewer women arrived within four hours after onset than men (27% vs. 33%; adjusted odds ratio, 0.8; 95% confidence interval, 0.7–0.9).

“Fewer women present themselves within four hours from stroke onset than men and consequently less often receive thrombolytic treatment,” the authors write.
