Cardiovascular risk factors and pericardial fat volume as predictors of coronary atherosclerosis burden in postmenopausal women: A retrospective, single center study.

Abstract

Little is known about the clinical relevance of pericardial fat volume (PFV), compared to other conventional cardiovascular risk factors, as predictors of coronary atherosclerosis severity among postmenopausal women. Our main aim was to assess the association of PFV and cardiovascular risk factors with coronary atherosclerosis burden, including occlusive coronary artery disease (CAD) (luminal stenosis >50%), coronary artery calcium score (CAC)>100, and plaque types in postmenopausal women. Patients who had chest pain of angina and referred for 64-slice multi-detector CT (MDCT) angiography examination to exclude occlusive CAD presence were enrolled in this retrospective study. A total of 241 women with absence of menses for more than 2 consecutive years and not taking hormone replacement therapy were enrolled in the present study. Increased PFV(OR[CI] = 1.1 [1-1.3],p = 0.004), age (OR [CI] = 1.1 [1-1.4],p = 0.002), and diabetes mellitus (OR [CI] = 2 [1-4],p = 0.025)were significant predictors of occlusive CAD presence. Increased PFV(OR [CI] = 1.1 [1-1.4],p = 0.017)and increased age (OR [CI] = 1.2 [1.1-1.4],p < 0.001)were better predictors of CAC>100 than other cardiovascular risk factors. Regarding coronary plaque types, increased age (OR [CI] = 1.1 [1.1-1.3],p = 0.001)showed a significant association with coronary calcified plaque presence while increased body mass index(OR [CI] = 1.2 [1-1.4],p = 0.018)showed a significant association with coronary non-calcified plaque presence. Higher PFV values showed an independent association with occlusive CAD and significant coronary calcification. This may imply that increased PFV is likely associated with the development of advanced and severe phenotype of coronary atherosclerosis among postmenopausal women with suspected CAD.
