Rapid ventricular tachycardias associated with cilostazol use

Tex Heart Inst J. 2002;29(2):140-2.


A 92-year-old woman with normal systolic function had recently begun using the newly approved phosphodiesterase III inhibitor cilostazol when she was admitted with lower-extremity pain. Cilostazol is indicated for patients with intermittent claudication and contraindicated for patients with congestive heart failure. Two days after admission, the patient developed ventricular tachycardia. Cilostazol was discontinued, and shortly thereafter the ventricular tachycardia subsided. In this case, cilostazol was apparently an important predisposing factor for ventricular tachycardia.
