PG - 631-5 AB - BACKGROUND: Several pathologic processes can cause myocardial injury, which is followed by cardiac remodeling and congestive heart failure (CHF). Cardiac troponin T (cTnT), a specific and sensitive marker of myocardial injury, has been related to long-term outcome in patients with CHF, so the relationship between cTnT and other biochemical markers associated with the pathophysiology of CHF was investigated in the present study. METHODS AND RESULTS: Between February 2004 and December 2005, 145 consecutive hospitalized patients (mean left ventricular ejection fraction (LVEF) 31.6+/-0.9%) with CHF were divided into low (<0.01 ng/ml) and high (> or =0.01 ng/ml) serum cTnT groups. Correlations with other prognostic biochemical markers, including brain natriuretic peptide (BNP), type I collagen C-terminal telopeptide (ICTP), procollagen type III peptide (PIIIP), renin, norepinephrine (NOREPI), C-reactive protein (CRP), cholesterol, hemoglobin (Hb), uric acid and HbA1c were examined. cTnT was high in 46 (32%) and low in 99 (68%) patients at baseline. Patients with high cTnT had abnormally high blood concentrations of BNP (p<0.0001), ICTP (p<0.0001), PIIIP (p=0.0006), NOREPI (p=0.0119), CRP (p=0.0003), uric acid (p=0.0026) and HbA1c (p=0.0361). In contrast, concentrations of cholesterol and Hb were significantly lower in patients with high cTnT (p=0.0319 and 0.0005, respectively). Death from or rehospitalization for CHF occurred in 41% in the high vs 9% in the low cTnT group (p=0.0002). Univariate analysis showed that high cTnT (p=0.0005), BNP (p=0.0001), renin (p=0.0158), NOREPI (p=0.0094), old age (p=0.0390), low LVEF (p=0.0231) and high New York Heart Association (NYHA) class (p=0.0006) were predictors of death from or rehospitalization for CHF. By multivariate analysis including BNP, NOREPI, age, LVEF and NYHA class, high cTnT and renin remained as significant predictors. CONCLUSIONS: Patients with ongoing myocardial injury and high cTnT had associated findings consistent with activation of the sympathetic system, synthesis of cardiac fibrosis, inflammation and metabolic abnormalities. By multivariate analysis, high cTnT and renin remained significant predictors of death or rehospitalization.
