Cardiac troponin T (cTnT) predicts death and cardiovascular outcomes in clinically stable patients with end-stage renal disease. Because this protein is synthesized exclusively in myocardial cells, its predictive power for these outcomes may be because it reflects, besides cardiac ischemia, left ventricular (LV) mass, which is a strong predictor of cardiovascular death in this population per se. We tested the relationship between cTnT level and LV mass and the predictive power of this cardiac protein for all-cause and cardiovascular mortality in a cohort of hemodialysis patients (n = 199) without acute coronary syndrome and heart failure followed up for an average of 35 months (range, 0.8 to 52 months). cTnT was measured by means of a third-generation electrochemiluminescence immunoassay. cTnT level was related directly to interventricular septum (r = 0.36; P < 0.001) and posterior wall thickness (r = 0.40; P < 0.001), as well as LV mass (r = 0.45; P < 0.001). On multivariate analysis, after age, LV mass was the strongest independent predictor of cTnT level (β = 0.28; P < 0.001). Serum cTnT level was significantly related to all-cause and cardiovascular mortality on univariate analysis (P < 0.001). On multivariate Cox regression analysis, the adjusted risk for all-cause death was 2.39 times (95% confidence interval [CI], 1.13 to 5.06; P = 0.02) greater in patients in the third cTnT tertile than the first tertile, and a similar pattern emerged for cardiovascular mortality (hazard ratio, 2.35; 95% CI, 1.01 to 5.49; P = 0.048). In hemodialysis patients, plasma cTnT level is independently related to LV mass and predicts all-cause and cardiovascular mortality. These data support the hypothesis that this marker can be usefully applied for risk stratification in clinically stable dialysis patients.
