Relationship of epicardial adipose tissue volume with coronary atherosclerosis and myocardial bridge / 中国医学影像技术

ABSTRACT

Objective: To explore the relationship of epicardial adipose tissue (EAT) volume with coronary atherosclerosis and myocardial bridge (MB). Methods: Imaging data of 375 patients who underwent coronary CTA were analyzed retrospectively, including 116 cases of atherosclerosis (plaque group), 78 cases of MB (MB group), 35 cases of MB with atherosclerosis (MB+plaque group) and 146 normal ones (normal group). The volume of EAT was measured manually and compared among 4 groups. Results: EAT volume of plaque group, MB group, MB+plaque group and normal group were (110.76+37.17)cm3, (104.97+36.72)cm3, (112.02+45.32)cm3 and (91.06±34.27)cm3, respectively. EAT volume of plaque group, MB group, MB+plaque group were significantly higher than that of normal group (P=0.001, 0.031, 0.043. There was no difference among plaque group, MB group and MB+plaque group (all P>0.05). Conclusion: Patients with MB have higher EAT volume than those with normal coronary artery, presenting higher potential risk of developing coronary atherosclerosis.
