ObjectiveCurrent methods of risk-stratification in patients with type 2 diabetes are suboptimal. The current study assesses the ability of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high sensitivity cardiac troponin T (hs-cTnT) to improve the prediction of cardiovascular events and death in patients with type 2 diabetes.Research Design and MethodsA nested case-cohort study was performed in 3,862 patients who participated in the Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation trial.ResultsSeven hundred and nine (18%) patients experienced a major cardiovascular event (composite of cardiovascular death, non-fatal myocardial infarction or non-fatal stroke) and 706 (18%) died during a median of 5 years follow-up. In Cox regression models, adjusting for all established risk predictors, the hazard ratio [HR] for cardiovascular events for NT-proBNP was 1.95 per 1 standard deviation [SD] increase (95% confidence interval [CI] 1.72-2.20) and the HR for hs-cTnT was 1.50 per 1 SD increase (95% CI 1.36-1.65). The HRs for death were 1.97 (95% CI 1.73-2.24) and 1.52 (95% CI 1.37-1.67), respectively. The addition of either marker improved 5-year risk classification for cardiovascular events (net reclassification index in continuous model, 39% for NT-proBNP and 46% for hs-cTnT). Likewise, both markers greatly improved the accuracy with which the 5-year risk of death was predicted. The combination of both markers provided optimal risk discrimination.ConclusionNT-proBNP and hs-cTnT appear to greatly improve the accuracy with which the risk of cardiovascular events or death can be estimated in patients with type 2 diabetes.
