The relation between pericoronary fat thickness and density quantified by coronary computed tomography angiography with coronary artery disease severity

To study the correlation between epicardial fat thickness (EFT), pericoronary fat thickness (PCFT), and pericoronary fat density (PCFD) with the existence and severity of coronary artery disease (CAD). This cross-sectional study included 210 patients referred for multislice CT angiography. Group I n...

Description
Summary:To study the correlation between epicardial fat thickness (EFT), pericoronary fat thickness (PCFT), and pericoronary fat density (PCFD) with the existence and severity of coronary artery disease (CAD). This cross-sectional study included 210 patients referred for multislice CT angiography. Group I normal CTCA, Group II patients had non-obstructive atherosclerosis, and Group III patients had obstructive atherosclerosis. All patients underwent a clinical examination, history taking, and multislice CT angiography. The mean EFT was significantly greater in group III (10.43 ± 2.31 mm) compared to groups II (6.30 ± 1.61 mm) and I (5.06 ± 1.14 mm). The mean PCFT was significantly greater in group III (17.96 ± 2.89 mm) compared to group II (11.47 ± 2.51 mm) and group I (9.67 ± 1.99 mm). PCFD was significantly higher adjacent to the lesion (−80.47 ± 29.14) compared to the normal segment (−109.03 ± 35.24), higher in the obstructive group (−59.44 ± 20.10) compared to the non-obstructive group (−101.51 ± 20.23), but lower in calcified lesions (−89.58 ± 28.94) compared to non-calcified (−75.01 ± 29.20), and mixed lesions (−74.83 ± 26.90). EFT and PCFT cut-off values for predicting obstructive CAD were 8.3 and 12.4 mm, respectively, with 87.1% and 92.9% sensitivity and 92.9% and 86.4% specificity, respectively. There is a significant association between epicardial fat thickness, pericoronary fat thickness and density with the severity of coronary artery disease.
