Abstract
Background Plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) has been reported as a predictor for ischemic stroke in general population. However, predictive value of plasma NT-proBNP for acute ischemic stroke in patients on chronic hemodialysis has not been well established. The aim of this study was to determine whether NT-proBNP could predict acute ischemic stroke in patients on chronic hemodialysis. Methods This study was designed prospectively. Clinical, laboratory, and echocardiographic variables were assessed in 72 patients on chronic hemodialysis. The plasma levels of NT-proBNP were measured by immunoassay. Results During the follow-up period of 45 months, 11 patients had an acute ischemic stroke. The Kaplan- Meier plot showed an increased frequency of acute ischemic stroke in patients with plasma levels of NTproBNP above the median values compared to patients with lower concentrations (P = 0.028). The multivariate Cox proportional hazard models showed that the NT-proBNP was a significant independent predictor of acute ischemic stroke after adjustment for age, sex, mean blood pressure, diabetes, serum cholesterol levels, left ventricular mass index, and left ventricular fractional shortening (HR 6.66, 95% CI, 1.22-36.48, P = 0.029). Conclusions Our data suggest that plasma NTproBNP levels predict the risk of acute ischemic stroke in patients on chronic hemodialysis.
