The Impact of Risk Burden Differences between Men and Women on the Clinical Course of Ischemic Stroke

BackgoundOur objective is to assess the impact of varying risk profiles in men and women on the clinical picture of ischemic stroke.Materials and MethodsThe study involved 185 patients, 100 women and 85 men. We assessed the patients' neurological status upon admission, 1 and 2 weeks following stroke onset, using the Scandinavian Stroke Scale and the Barthel Index; stroke syndromes according to the Oxfordshire Classification; their etiology and pathogenesis according to the Trial of Org 10172 in Acute Stroke Treatment; and the prevalence of vascular risk factors. We used cranial magnetic resonance imaging to locate infarcts.ResultsWomen had more total anterior circulation infarct subtype strokes, whereas men had more posterior circulation infarct and lacunar infarct. On neuroimaging, women had more infarcts in the middle cerebral artery circulation, whereas men had more in the brain stem and/or cerebellum. Women had a higher prevalence of atrial fibrillation (AF) and coronary artery disease, whereas men were more likely to smoke and abuse alcohol. Women had more cases of cardioembolism, whereas men had more strokes caused by atherosclerosis of large vessels.ConclusionsIn the present study, heart diseases, such as coronary artery disease and AF, were more prevalent among women. It seems that AF is a risk factor with significant impact on the epidemiological differences regarding ischemic stroke in men and women.
