Ifosfamide and Atrial Fibrillation

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. Its prevalence in cancer patients undergoing treatment with radiation or chemotherapeutic agents has been on the rise. The most common offending agents are alkylating agents and anthracyclines causing various types of arrhythmias, including AF. We report a case of a 62-year-old male who was diagnosed with stage IV pleomorphic rhabdomyosarcoma and was started on chemotherapy with a mesna-ifosfamide and doxorubicin (MAI) regimen. He developed AF with a rapid ventricular rate soon after his second cycle of treatment, which got better with the initiation of beta-blocker therapy...

In our aging population the incidence of cancer is increasing in the elderly. We are thus facing a new challenge especially considering incidence of cardiovascular diseases (CVD) in this patients population. Overall survival of cancer patients has significantly improved therefore cancer has become in many cases a chronic disease. We are about to be treating patients who either may develop a new CVD or their current CVD may deteriorate. Cancer can cause various cardiovascular conditions locally (pressure in mediastinum, effusions) or systemically (increased risk of pulmonary embolism, arrhythmias, carcinoid heart disease)...
