Late, late doxorubicin cardiotoxicity.

Cardiac toxicity is a major complication which limits the use of adriamycin as a chemotherapeutic agent. Cardiomyopathy is frequent when the total dose exceeds 600 mg/m2 and occurs within one to six months after cessation of therapy. A patient is reported who developed progressive cardiomyopathy two and one-half years after receiving 580 mg/m2 which apparently represents late, late cardiotoxicity.
