Abstract
Vascular inflammation is linked with the pathogenesis of vasospastic angina (VSA). Recent studies reported the potential of pericoronary adipose tissue attenuation as shown on coronary computed tomography angiography to detect coronary inflammation. This report presents a case of myocardial infarction with nonobstructive coronary arteries potentially complicated with VSA that demonstrated reduction of inflammation after symptom improvement with calcium channel-blocker treatment as assessed by serial examination of pericoronary adipose tissue attenuation. This case highlighted the feasibility of a noninvasive assessment of pericoronary adipose tissue attenuation to evaluate the disease activity of VSA and guide patient management.
