Objective · To explore the occurrence risk and clinical significance of glomerular filtration rate (GFR) level and acute ischemic stroke in middle-aged and elderly population. Methods · The clinical data of 292 hospitalized patients in the Department of Neurology at the No.908 Hospital of the Peoples Liberation Army Joint Logistics Support Force Jan. 2016 to Jun. 2018 were retrospectively analyzed, including gender, age, diastolic blood pressure, body mass index, smoking and drinking history, erythrocyte count, brain images, and the level of blood glucose, low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, total cholesterol, GFR, blood urea nitrogen, blood uric acid, serum creatinine, glutamic-oxaloacetic transaminase, homocysteine. According to the GFR level, patients were divided into normal GFR group and low GFR group. The clinical characteristics were compared between two groups. Multivariate Logistic regression analysis was used to investigate the relationship between GFR level and the occurrence of acute ischemic stroke. Results · The number of patients in normal GFR group and low GFR group was 154 (52.74%) and 138 (47.26%), respectively. Chi-square test or t test analysis showed that there was no significant difference in gender, body mass index, smoking history, drinking history, erythrocyte count, blood glucose, low density lipoprotein-cholesterol, high density lipoprotein-cholesterol, total cholesterol, glutamic-oxaloacetic transaminase and homocysteine between two groups, and significant difference in age, diastolic blood pressure, GFR, blood urea nitrogen, blood uric acid, serum creatinine (all P<0.05). The incidence rate of acute ischemic stroke in normal GFR group and low GFR group was 41.56% (64/154) and 59.42% (82/138), respectively (χ29.291, P0.002). Compared with the normal GFR group, the occurrence risk OR (95% CI) of acute ischemic stroke in lower GFR group was 2.06 (1.29–3.29) (P0.002) and 2.04 (1.01–4.12) (P0.047) before and after adjusted the related risk factors. Conclusion · The low GFR levels are associated with the occurrence of acute ischemic stroke in middle-aged and elderly population.
