Abstract:
The 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) regimen is widely used in the management of breast cancer. The common cardiotoxic effects of doxorubicin include congestive heart failure and left ventricular dysfunction, and those of cyclophosphamide include pericarditis, myocarditis, and congestive heart failure. It has been postulated that cardiotoxicity of 5-fluorouracil presents as coronary artery diseases (eg, angina). Cardiomyopathy is a common outcome following treatment with the FAC regimen. We report on a 52-year-old woman with cardiomyopathy following chemotherapy and radiation therapy. The patient did not respond well to b-blockers and angiotensin-converting enzyme inhibitors. After the addition of exogenous phosphocreatine, the patient's cardiac condition improved significantly.
