N-terminal pro brain natriuretic peptide in the management of patients in the medical emergency department (PROMPT): correlation with disease severity, utilization of hospital resources, and prognosis in a large, prospective, randomized multicentre trial

Aims: N-terminal pro brain natriuretic peptide (NT-proBNP) is a potent marker of heart failure and other cardiac diseases. The value of NT-proBNP testing in the medical emergency department (ED) was assessed in patients >65 years old. Methods and results: This large, prospective, randomized, controlled, multicentre trial was conducted in six medical EDs. Data for evaluation of the primary endpoint of hospitalization were available for 1086 patients. Median NT-proBNP was 582 pg/mL. A total of 16% of patients presented with NT-proBNP 1800 pg/mL (high). NT-proBNP was positively correlated with hospital admission [ odds ratio (OR) for high vs. low 2.9, P 1800 pg/mL) were more likely to be admitted to the hospital (P < 0.05) and IMC/ICU (P < 0.05), whereas patients with low open NT-proBNP (<150 pg/mL) were less likely to be admitted (P < 0.05) compared with patients with blinded NT-proBNP. Conclusion: Although NT-proBNP does not affect overall hospitalization, it is associated with better stratification of patient care and is strongly correlated with subsequent utilization of hospital resources and prognosis
