Abstract:
Objective:To investigate the influencing factors of the outcome of patients with acute minor ischemic stroke (AMIS) in medium- to high-altitude areas.Methods:Patients with AMIS admitted to Qinghai Provincial People's Hospital between October 2016 and July 2019 were included retrospectively. At 90 days after onset, the modified Rankin Scale was used to evaluate the outcome, 0-1 was defined as good outcome and ≥2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of the outcome. Results:A total of 102 patients with AMIS in high-altitude areas were enrolled, including 58 males (56.9%), aged 61.41±4.72 years. One patiente experienced intracranial hemorrhage, 19 (18.6%) experienced recurrent ischemic stroke, and 24 (23.5%) had poor outcome. Multivariate logistic regression analysis showed that recurrent ischemic stroke (odds ratio [ OR] 10.680, 95% confidence interval [ CI]1.824-62.540; P=0.009), higher low-density lipoprotein cholesterol ( OR 3.980, 95% CI 1.654-6.711; P=0.014), hyperviscosity ( OR 2.374, 95% CI 1.679-5.263; P=0.027), and higher hematocrit ( OR 8.545, 95% CI 1.869-49.978; P=0.010) were the independent risk factors for poor outcome, while dual antiplatelet therapy after admission ( OR 0.876, 95% CI 0.769-0.978; P=0.023) was an independent protective factor for good outcome. Conclusions:More than 1/5 of patients with AMIS in medium- to high-altitude areas have poor outcome at 90 days after onset. Independent risk factors for poor outcome include recurrent ischemic stroke, higher low-density lipoprotein cholesterol, hyperviscosity and higher hematocrit, while dual antiplatelet therapy after admission is independently associated with good outcome.
