Abstract

Abstract Aims To evaluate the sex-specific predictive value of N-terminal pro B-type natriuretic peptide (NT-proBNP), high sensitivity cardiac troponin T (hs-cTnT) and creatine kinase myocardial band (CK-MB) for 10-year risk prediction of coronary heart disease (CHD), stroke, heart failure (HF) and composite outcomes. Methods Five-thousand four-hundred thirty individuals (mean age 68.6 years, 59.9% women) from the Rotterdam Study, with biomarker measurements between 1997 and 2001, were included. Participants were followed until 2015. We fitted ‘basic’ models using traditional cardiovascular risk factors. Improvements in c-statistics and net reclassification improvement (NRI) for events and non-events were calculated. Results During a median follow-up of 14 years, 747 (13.8%), 563 (10.4%), and 664 (12.2%) participants were diagnosed with CHD, stroke, and HF, respectively. NT-proBNP improved the discriminative performance of the ‘basic’ model for all endpoints (c-statistic improvements ranging from 0.007 to 0.050) and provided significant event-NRI for HF (14.3% in women; 10.7% in men) and for stroke in men (9.3%). The addition of hs-cTnT increased c-statistic for CHD in women by 0.029 (95% CI, 0.011–0.047) and for HF in men by 0.034 (95% CI, 0.014–0.053), and provided significant event-NRI for CHD (10.3%) and HF (7.8%) in women, and for stroke (8.4%) in men. The added predictive value of CK-MB was limited. Conclusion NT-proBNP and hs-cTnT provided added predictive value for various cardiovascular outcomes above traditional risk factors. Sex differences were observed in the predictive performance of these biomarkers.
