We assessed the relative contributions of N-terminal pro-B-type natriuretic peptide (NTBNP) and high sensitivity cardiac troponin (hsTnT) to the prediction of death and cardiovascular (CV) events in 5597 (with complete data) of 8561 patients with type 2 diabetes (T2DM) and CV disease (CVD) and/or chronic kidney disease (CKD) enrolled in the Aliskiren Trial in Type 2 Diabetes Using Cardiorenal Endpoints (ALTITUDE). We analysed Harrell’s C-statistics (Cs) to estimate Cox model performance to predict death (n= 473) and a CV composite outcome (CVCO: CV death, resuscitated cardiac arrest, nonfatal myocardial infarction, stroke or heart failure hospitalization, n= 1129) after a median follow-up of 2.6 years, using a base model (BM) of 19 clinical baseline variables. The Cs for predicting death in the BM (0.724) was augmented by adding hsTnT (0.744, p= 0.002) which was further improved by NTBNP (0.779, p <0.001). Similarly, the BM for predicting CVCO Cs (0.716) was improved by hsTnT (0.732, p= 0.001) and enhanced further by including NTBNP in the model (0.763, p <0.001). Notably, NTBNP by itself was as predictive as BM plus hsTNT for predicting death (both 0.744, p= 1.0) and the CVCO (0.732 vs. 0.721, p= 0.27). In patients with T2DM and CVD or/and CKD, NTBNP was the major prognostic factor and should be considered for risk stratification.
