Sipuleucel-T associated inflammatory cardiomyopathy: a case report and observations from a large pharmacovigilance database.

Patients with CV risk factors who are receiving sipuleucel-T may be at higher risk for congestive heart failure, myocardial ischemia, and supraventricular tachycardia. Electrocardiograms during weekly sipuleucel-T infusions and left ventricular function monitoring with echocardiogram should be considered in these patients. Our findings are suggestive of another rare presentation of T-cell-mediated CV toxicity with cancer immunotherapy.
