Myocardial Infarction With Nonobstructive Coronary Arteries Assessed by 11C-Acetate Cardiac PET.
Abstract
C-acetate PET can quantify myocardial blood flow and oxidative metabolism (kmono) with a single imaging study. We present a 63-year-old man with myocardial infarction with nonobstructive coronary arteries due to vasospasm, who underwent C-acetate PET after antispastic medication. By quantifying myocardial blood flow and kmono, C-acetate PET could detect the initial ischemic insult by vasospasm and sufficient amount of remaining viable myocardium, while excluding significant inducible ischemia. We suggest that C-acetate PET can be a clinically valuable tool for assessing the pathophysiology of myocardial infarction with nonobstructive coronary arteries.
