Determination of a predictive cutoff value of NT-proBNP testing for long-term survival in ED patients with acute heart failure.
The main objective of this study was to determine a predictive cutoff value for plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) that could successfully predict the long-term (4-year) survival of patients with acute heart failure (HF) at the time of admission to the emergency department (ED). To our best knowledge, our study is the first research done to identify a predictive cutoff value for admission NT-proBNP to the prescriptive 4-year survival of patients admitted to ED with acute HF diagnosis. ⋯ Elevated NT-proBNP levels at the time of admission are a strong and independent predictor of all-cause mortality in patients with acute HF 4 years after admission. Furthermore, the optimal cutoff level of NT-proBNP used to predict 4-year survival had high sensitivity. However, especially in the case of long-term survival, additional prospective, large, and multicenter studies are required to confirm our results.
