A 40-year-old male patient with carcinoma of the tonsil was put on a 5
-fluorouracil and cisplatinum regimen. On day 2 during 5-fluorouracil
infusion, he had features of myocardial ischemia manifesting as angina
and ST-elevation in ECG. These vasospastic ischemic changes subsided
after nitroglycerine plus nifedipine therapy. Such vasospastic toxicit
y of 5-fluorouracil is rare and few such cases have been reported.
