[Cardiotoxic effect of anthracycline antibiotics].

Anthracycline antibiotic (Rubidomycin and Adriamycin) are often used for treatment of acute leukemia and variety of solid tumors. The use of greater doses of these agents is mostly limited by the damage of the cardiac muscle and by heart failure. The Rubidomycin cardiac toxicity analysis of children with acute leukemia has been considered in this paper. The results were obtained by investigating 53 patients who received this drug. They were classified in subgroups in relation to the total dose administered. Acute or chronic myocardial damage appeared in 6 children. The subgroup incidence of damage is directly proportional to the total dose administered.
