Impact of epicardial adipose tissue volume quantified by non-contrast electrocardiogram-gated computed tomography on ergonovine-induced epicardial coronary artery spasm

Endothelial dysfunction of the coronary artery is thought to lead to the development of coronary spasms. Epicardial adipose tissue may be a marker of coronary atherosclerosis. This study investigated the diagnostic impact of epicardial fat volume (EFV), quantified with non-contrast electrocardiogram (ECG)-gated computed tomography (CT), on ergonovine-induced coronary spasms.We included 97 patients with suspected coronary spastic angina who...
