Abstract:
Although men have a higher rate of stroke than women, it is not clear whether women have a worse outcome after adjusting for confounders such as vascular risk factors, age, stroke severity, and reperfusion therapy. We evaluated sex differences on 90-day functional outcomes after stroke in a multicenter study in Vietnam. Methods: We recruited patients presenting with ischemic or hemorrhagic stroke at 10 stroke centers in Vietnam for a period of 1 month from 1 August 2022 to 31 August 2022. We reviewed the patient’s clinical demographics, time from symptom onset to hospital admission, stroke classification, stroke subtype, stroke severity, characteristics of reperfusion therapy, and 90-day clinical outcome. We compared functional outcomes and predisposing factors at day 90 between men and women after an ischemic and hemorrhagic stroke. Poor outcome was defined as modified Rankin Scale 3–6. Results: There were 2300 stroke patients included. Men accounted for 61.3% (1410) of participants. Compared to men, women were older (67.7 ± 13.9 vs 63.7 ± 13.3, P 〈 0.001), had a higher rate of diabetes mellitus (21.1% vs 15.3%, P 〈 0.001), a lower rate of tobacco use (1.0 % vs 23.6%, P 〈 0.001), and a lower body mass index (21.4 ± 2.70 vs 22.0 ± 2.72, P 〈 0.001). There was a higher rate of intracranial hemorrhage (ICH) in men (21.3% vs 15.6%, P = 0.001), whereas the rate of subarachnoid hemorrhage was higher in women (6.2% vs 3.0%, P 〈 0.001). For ischemic stroke, door-to-needle time (36.9 ± 17.6 vs 47.8 ± 35.2 min, P = 0.04) and door-to-recanalization time (113.6 ± 51.1 vs 134.2 ± 48.2, P = 0.03) were shorter in women. There was no difference in 90-day functional outcomes between sexes. Factors associated with poor outcomes included age ⩾50 years (adjusted odds ratio (aOR): 1.75; 95% confidence interval (CI): 1.16–2.66), history of stroke (aOR: 1.50; 95% CI: 1.15–1.96), large artery atherosclerosis (aOR: 5.19; 95% CI: 3.90–6.90), and cardioembolism (aOR: 3.21; 95% CI: 1.68–6.16). Factors associated with mortality in patients with acute ischemic stroke included a history of coronary artery disease (aOR: 3.04; 95% CI: 1.03–8.92), large artery atherosclerosis (aOR: 3.37; 95% CI: 2.11–5.37), and cardioembolism (aOR: 3.15; 95% CI: 1.20–8.27). Conclusion: There were no sex differences in the clinical outcome of stroke and ischemic stroke in this prospective cohort of hospitalized Vietnamese patients.
