Abstract

Background: Troponin T is an established marker of myocardial ischemia. We speculated that the role of the new high-sensitive troponin T (hs-cTnT) might expand towards non-ischemic myocardial disease, indicate disease severity and allow for prognostication in chronic heart failure. Methods: Hs-cTnT (Roche Diagnostics, Mannheim, Germany) was assessed in 233 individuals with chronic heart failure (n=149) or healthy controls (n=84). Results: Hs-cTnT was significantly elevated in patients with chronic heart failure [0.018 ng/mL, interquartile range (IQR) 0.009-0.036 ng/mL, vs. controls 0.003 ng/mL, 0.003-0.003 ng/mL, p<0.001] and positively correlated with N-terminal pro-b-type natriuretic peptide (NT-proBNP) (r=0.79, p<0.001). Hs-cTnT increased stepwise and signitificantly according to clinical (NYHA stage) as well as functional (LV ejection fraction, fluid retention) severity (each p<0.001). At a binary cutpoint of 0.014 ng/mL, hs-TropT was a significant predictor of all-cause mortality and all-cause mortality or rehospitalization for congestive heart failure (each p <= 0.01). Of note, the prognostic value of hs-TropT was independent and additive to that of NT-proBNP. Conclusions: Hs-cTnT increases stepwise with the severity of symptoms and LV dysfunction and offers important prognostic information in chronic heart failure, independently from and additive to NT-proBNP. The utility of hs-cTnT expands beyond acute myocardial ischemia and towards chronic heart failure.
