Abstract

The anthracyclines are antibiotics effective in the treatment of many malignancies. However, their usefulness is limited by the development of potentially acute or chronic cardiotoxicity. No definitive guidelines exist for monitoring cardiac function during and after anthracyclines although methods have been suggested. Electrocardiograms and echocardiograms are routinely utilized for noninvasive assessment of myocardial function. The aim of the study was to assess the effects of doxorubicin on ventricular repolarization time indexes, as they have been shown to be effective in the identification of electrical myocardial instability and hence in the identification of the risk for either arrhythmia or heart failure. Electrocardiographic parameters were compared in 27 cancer patients before and after chemotherapy including doxorubicin. The data of the present study show that after only a short period of treatment with doxorubicin there is a significant increase in ventricular recovery time indexes (QTc dispersion and 'Adjusted' QTc dispersion). The relation between the electrophysiological response to doxorubicin and the potential cardiotoxic effect of this drug remains to be established through prospective studies.
