The study was performed to describe the time course of serum cardiac troponin T (cTnT) elevations for the early detection of anthracycline cardiotoxicity. cTnT was analyzed serially in 78 patients with hematological malignancies receiving 142 treatment cycles including various anthracyclines. cTnT positivity was defined as an increase in cTnT >or=0.03 ng/ml and was observed in 12 patients (15%) during 16 treatment cycles (11%). Peak cTnT levels were observed on day +21.5 (median, range: day +6 to day +35) after initiation of anthracycline therapy. cTnT positivity lasted >or=3 days in 63% of cycles and began to occur after a median of two anthracycline doses. Follow-up echocardiography in 28 patients showed a greater decrease in left ventricular ejection fraction (LVEF) in cTnT-positive patients compared to the cTnT-negative group (10% vs 2%, p=0.017). Age, gender, and pretreatment LVEF had no influence on the occurrence of cTnT positivity. Serial measurement of serum cTnT reveals delayed subclinical myocardial damage even after minor anthracycline exposure, may identify patients at risk for subsequent myocardial dysfunction, and suggests prolonged damage to the cardiac myofibrillar system.
