Abstract

Cardiotoxicity is a common complication of chemotherapy. The aim of this study was to assess the cardiotoxicity of anticancer drugs using tissue Doppler imaging. A prospective study was carried out using patients with early breast cancer (72 women, median age: 57 ± 12 year) and other inclusion and exclusion criteria. Inclusion criteria were treatment with epirubicin, trastuzumab, fluorouracil, cyclophosphamide, taxotere, and taxolo; left ventricular ejection fraction (LVEF) of more than 50%; and absence of important pathologies. Exclusion criteria were presence of known heart disease, earlier exposure to mediastinal irradiation, and earlier chemotherapy. On the basis of treatment, patients were divided into five groups: A=fluorouracil-epirubicin-cyclophosphamide (FEC), B = FEC + trastuzumab, C = trastuzumab, D = FEC + taxotere, and E = FEC + taxol + trastuzumab. Cardiological evaluation including electrocardiogram and echocardiogram was carried out at baseline, 3 months, and 6 months after the start of chemotherapy in all patients. The Doppler patterns were integrated with other echo parameters (tissue Doppler). Significant changes (P < 0.05) in the echo parameters of the tissue Doppler were observed in treated patients during follow-up but not in LVEF. In conclusion, the tissue Doppler is more sensitive than standard Doppler in the study of diastolic function and LVEF in the study of systolic function. The tissue Doppler should integrate conventional echocardiography in the study of left ventricular function in patients treated with anticancer drugs. It is very important to reduce the risk of cardiovascular complications, especially heart failure, in breast cancer survivors.
