A case of a male 66 years-old patient who presented with a clinical picture of Prinzmetal's variant angina early in the evolution of an acute myocardial infarction is reported. Transient elevation of ST-segment was documented on Holter monitoring in association with angina at rest as well as asymptomatic episodes of ST-segment changes. Significant two-vessels obstructive lesions (left anterior descending and circumflex arteries) was present. As variant angina had several recurrences in spite of medical therapy with nitrates and calcium antagonists, the patient was submitted to coronary by-pass surgery associated to plexectomy. A Thallium myocardial scintigraphy suggests that a peroperative infarction had occurred. The patient was asymptomatic at six months follow-up.
