ABSTRACT
BACKGROUND: Sex-specific risk predictive performance 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 individual and composite cardiovascular outcomes remains unclear.
OBJECTIVES: To evaluate the sex-specific predictive value of NT-proBNP, hs-cTnT and CK-MB for 10-year risk prediction of coronary heart disease (CHD), stroke, heart failure (HF) and composite outcomes.
METHODS: 5430 individuals (mean age 68.6 years, 59.9% women) from the Rotterdam Study, with biomarker measurements between 1997-2001, 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-net reclassification improvement (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.
