Coronary artery spasm induced by 5-fluorouracil.

The frequently used chemotherapeutic drug 5-fluorouracil (5-FU) is known to cause angina pectoris and arrhythmias; myocardial infarction and sudden cardiac death could occur. Potential reasons for these phenomena range from toxic/metabolic disturbances to coronary artery spasms. This report shows angiographically proven spasmophilia of the coronary arteries and contributes to the understanding of angina pectoris occurring during treatment with 5-FU. Thus, verapamil type calcium antagonists as well as nitrates should be administered primarily in patients with coronary artery disease and in all patients who had been symptomatic during 5-FU administration in order to prevent further episodes.
