Background. Coronary artery disease (CAD) is the foremost cause of death in the most developed societies. Plaque formation in epicardial coronary arteries and ensuing inflammation are a known pathophysiologic factor of CAD.Objectives. We aimed to separately and simultaneously evaluate the correlation between pericardial fat pad volume and overall peri-coronary epicardial adipose tissue (EAT) thickness with coronary calcium score (CCS) to improve risk stratification of CAD.Methods. We retrospectively reviewed patients who underwent a non-invasive contrast-enhanced coronary multidetector CT (MDCT) angiography. Peri-coronary EAT thickness, pericardial fat pad volume and CCS were obtained by an expert radiologist from the patients coronary multidetector CT (MDCT) angiography.Results. We included 141 symptomatic patients (86 men, 55 women) with an average age of 53.53 ± 12.92. An increment of overall peri-coronary EAT thickness (1/3 × (left anterior descending artery (LAD) + left circumflex artery (LCx) + right coronary artery (RCA)) was associated with a 49% increase in the odds for the presence of coronary artery calcification (CAC) (P = 0.004). Significant predictability of peri-coronary EAT-average was seen in diagnosing calcified plaque. Pericardial fat pad volume was positively correlated with overall peri-coronary EAT thickness in age and body mass index (BMI)-adjusted linear regression models, (P < 0.001).Conclusion. Our results amplify previous idea that peri-coronary EAT and pericardial fat pad volume might act as useful markers and better indicators of CCS based on Agatston score in comparison with BMI or body weight in order to reveal subsequent CADs.
