Abstract
Small-vessel vasospasm has been speculated upon as a possible cause of chest pain in patients with normal-appearing coronary angiograms. In this report, a patient who experienced typical chest pain during acetylcholine testing, which caused ST segment elevation without epicardial coronary spasm, is presented. This finding suggests that small-vessel vasospasm may be involved in the induction of myocardial ischemia in patients with normal epicardial coronary arteries.Keywords
