N-Terminal Pro Brain Natriuretic Peptide Reference Values in Community-Dwelling Older Adults

Abstract

This reference sample of apparently healthy asymptomatic older adults showed an age-related increment of NT-proBNP levels with URL markedly higher than the European Society of Cardiology recommended cut-off of 125 ng/L for the diagnosis of heart failure in ambulatory settings. Identifying URL in those ≥80 years remains complex. Our results attempt to provide a frame for the further investigation of age-specific NT-proBNP cut-offs in older adults. Considering the demographic changes, further evaluation of NT-proBNP URL in larger samples of older adults followed by the validation of age-specific cut-off values for the identification of heart failure in those 65 years or older are urgently needed.
