Does NT-proBNP testing aid in the diagnosis or exclusion of acute heart failure in acutely dyspneic patients in the emergency department?
In the emergency department, an NT-proBNP level below 300 pg/ml is a strong rule-out test for acute heart failure in patients presenting with acute dyspnea.
In acutely dyspneic patients seen in the ED setting, age-stratified NT-proBNP cutpoints may aid in the diagnosis of acute HF. An NT-proBNP <300 pg/ml strongly excludes the presence of acute HF.
