Background: Altered myocardial extracellular matrix turnover has been proposed as a major determinant of myocardial remodelling. Carboxy-terminal telopeptide of collagen type-I (CITP) represents a collagen type-I degradation-derived serum peptide. In this study we examined the independent and additive prognostic value of serum concentrations of CITP compared with well-known mortality predictors such as the N-terminal pro-brain natriuretic peptide (NT-proBNP) in chronic heart failure (CHF) patients. Methods: We studied 196 consecutive patients (126 male, mean age 69 ± 10 years), who were admitted for acute decompensation of the CHF syndrome. The study entry point was determined at the discharge of the patients after achieving a stable compensated status. The primary endpoint was cardiac mortality during a 12-month follow-up. Results: In the multivariate Cox proportional hazard model the levels of CITP remained a predictor of survival (hazards ratio 0.4 95% confidence interval 0.21-0.76, P = 0.005), independent of NT-proBNP levels. The stratified log-rank test (P < 0.001) showed that CHF patients characterized by low levels of both biomarkers had better survival (hazards ratio 0.12 95% confidence interval 0.04-0.35, P < 0.001) compared with patients characterized by high levels of both biomarkers. The negative predictive value of the combined measure for long-term adverse events was 94%. Conclusion: Serum levels of CITP were shown to be an independent and strong prognostic marker regarding survival in CHF patients. Furthermore, CITP levels had an additive prognostic value compared with NT-proBNP levels. These findings underline the detrimental role of myocardial fibrosis in the progression of heart failure and suggest a novel multi-marker approach for risk stratification in the CHF syndrome.
