ObjectiveThe main objective of this study was to determine a cutoff level of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) that could successfully predict the short- and long-term prognosis of patients with acute heart failure at the time of admission to the emergency department. The results of our study are presented in context with previously published literature. We believe that the present study will be useful and salutary for the progress of literature.MethodsN-terminal pro-B-type natriuretic peptide plasma levels were obtained from 100 patients with shortness of breath and left ventricular dysfunction upon admission to the emergency department. All patients underwent follow-up evaluations 30 days and 1 year after admission. The end point was defined as all-cause mortality.ResultsThe mean age of the patients in this study was 70.8 ± 11.6 years, and 51% were female. All-cause mortality at the 30-day and 1-year follow-up evaluations was 21.2% and 53.5%, respectively. We determined that the optimal NT-proBNP cutoff point for predicting 30-day mortality at the time of admission was 9152.4 pg/mL, with a 71.4% sensitivity and an 81.3% specificity (95% confidence interval, area under the curve: 0.726; P = .002). The optimal NT-proBNP cutoff point for predicting 1-year mortality at the time of admission was 3630.5 pg/mL, with an 83.0% sensitivity and a 52.2% specificity (95% confidence interval, area under the curve: 0.644; P = .014).ConclusionElevated NT-proBNP levels at the time of admission are a strong and independent predictor of all-cause mortality in patients with acute heart failure at 30 days and 1 year after admission. Furthermore, the optimal cutoff level of NT-proBNP used to predict 30-day and 1-year mortality had high sensitivity.Copyright © 2013 Elsevier Inc. All rights reserved.
