2-OR: Impact of N Terminal Pro B-Type Natriuretic Peptide and High Sensitivity Cardiac Troponin on the Prediction of Death and Cardiovascular Events in High-Risk Patients with Type 2 Diabetes

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
