Serum N-terminal pro-B-type natriuretic peptide as a predictor for future development of atrial fibrillation in a general population: The Hisayama study.

Abstract Background Biomarkers for predicting future development of atrial fibrillation (AF) have not been fully established in general populations. The aim of this study was to assess the predictive ability of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) for the development of AF. Methods and results A total of 3126 community-dwelling Japanese subjects aged ≥40 years without a history of AF in 2002 were followed up for a median of 10.2 years. Serum NT-proBNP levels at baseline were divided into four categories (≤54, 55–124, 125–299, and ≥ 300 pg/mL) according to the current guidelines and prior reports. The hazard ratios for the development of AF were estimated using a Cox proportional hazards model. During the follow-up period, 153 subjects developed new-onset AF. The age- and sex-adjusted cumulative incidence of AF increased significantly with higher serum NT-proBNP levels (p  Conclusions Serum NT-proBNP levels can be a risk biomarker for predicting future development of AF in a general Japanese population.
