Abstract:
Objective To evaluate the influence of C-reactive protein (CRP),insulin resistance (IR) and epicardial fat volume (EFV) on the extent of coronary atherosclerosis in patients with different body mass index(BMl).Methods One hundred and three patients with coronary artery disease were involved in current study who underwent 64-slice dual source CT and percutaneous coronary angiography.Measurements of height,weight,waist circumference (WC) were recorded,and BMI was calculated.All patients were divided into obesity group (n =45) and non-obesity group (n =58) based on BMI.EFV were calculated through 64-slice dual source CT.Blood samples were collected for biochemical examination.Gensini score were adopted to quantify the severity of coronary artery stenosis.The relationship between Gensini score and EFV,CRP and homeostasis model assessment-insulin resistance(HOMA-IR) index were statistical analyzed by SPSS16.0 software.Results The level of CRP,WC,EFV and BMI in obesity group were (11.0 ± 5.8) mg/L,(96.1 ± 7.0) cm,(122.7 ± 43.3) cm3,(27.9 ± 2.9) kg/m2 respectively,significantly higher than those in non-obesity group ((6.5 ± 3.4) mg/L,(86.4 ± 7.6) cm,(92.9 ± 39.5) cm3,(22.4 ± 1.9) kg/m2) and the differences were significant (t =2.24,6.74,3.64,11.74,and P ＜ 0.05).CRP were positively correlated with EFV (r =0.404,0.364,P ＜0.05) in both obesity and non-obesity group,While HOMA-IR were only associated with BMI in obese group(r =0.322,P ＜0.05).Gensini score in non-obesity groups were positively related with EFV and CRP (r =0.358,0.315,P ＜ 0.05),while in obesity groups were positively related with EFV,CRP and HOMA-IR(r =0.348,0.297,0.384; P ＜ 0.05).The associations between Gensini score and CRP were not significant in obesity group after adjusting BMI and WC.Multiple linear regression analysis showed that EFV and diabetes mellitus were independent risk factors of patient Gensini score.Conclusion Coronary atherosclerosis is positively related with EFV and CRP in all patients.While,coronary atherosclerosis is influenced by BMI,WC and HOMA-IR in obese group.EFV is an independent risk factor of coronary atherosclerosis.
