Abstract

While a number of studies have reported an association between apelin-13 and ischemic stroke, few have verified its clinical effect. We investigated the prognostic value of serum apelin-13 levels in patients with acute ischemic stroke (AIS). We prospectively recruited 244 AIS patients within 24 h after stroke onset, and 167 healthy controls. We assessed the serum apelin-13 levels using ELISA, and the severity of AIS using the National Institutes of Health Stroke Scale (NIHSS). The primary outcomes included death or major disability (modified Rankin Scale score, 3-6) and major disability (modified Rankin Scale score, 3-5). Secondary outcomes included recurrent stroke and combined events (all-cause death, or cardiovascular and cerebrovascular events). We found that the serum apelin-13 levels in the patients (38.63 ng/mL (interquartile range [IQR], 29.86-50.99)) were lower than those in the healthy controls (42.50 ng/mL [IQR, 31.25-59.17]) (P = 0.017). Patients with a NIHSS score ≤ 3 had higher apelin-13 levels than those with a NIHSS score > 3 (P = 0.048). At the 3-month follow-up, multivariate logistic regression analysis indicated an association between apelin-13 and death or major disability (OR 0.31; 95% CI 0.11-0.86; P = 0.024) and major disability (OR 0.32; 95% CI 0.11-0.90; P = 0.030). At the 1-year follow-up, the patients with high apelin-13 levels showed a lower incidence of stroke and combined events (Log-rank test P < 0.05). Our findings indicate that serum apelin-13 may be a potential prognostic biomarker for AIS.
