Amsacrine cardiotoxicity: assessment of ventricular function by radionuclide angiography.

Serial assessment of ventricular function by means of a nuclear medicine technique was performed in six patients with malignant disease receiving chemotherapy with amsacrine. Two patients who received treatment long enough so that greater than 580 mg/m2 of the drug was administered showed a significant decrease in left ventricular ejection fraction. Four patients who received total doses of 325-510 mg/m2 of amsacrine did not experience significant change in their cardiac function.
