Objectives:
Stroke is a major cause of long-term disability and death worldwide. Several studies have shown that women in general have more severe symptoms at arrival to hospital and are less likely to return home and independent living. Our aim with the present study was to update previous results concerning sex differences in baseline characteristics, stroke management, and outcome in a population study from Sahlgrenska University Hospital, Gothenburg, Sweden.
Methods:
This study included patients with acute ischemic and hemorrhagic stroke in 2014 at Sahlgrenska University Hospital. All data were collected from The Swedish National Stroke Registry (Riksstroke).
Results:
The study population consisted of 1453 patients, with 46.7% females. Women were 5 years older than men. There was no sex difference in acute stroke severity. Frequency of revascularization was equal between men and women. The stroke mortality rate was the same between the sexes. At 3-months follow-up, women had a worse functional outcome and a higher frequency of depression and post-stroke fatigue.
Conclusion:
Our results show that there are no sex differences in management of acute stroke. However, the cause of worse functional outcome in women at 3-months follow-up, independent of other risk factors, is not clear and warrants further investigations.
