ABSTRACT
Objective To investigate the relationship between body mass index (BMI) and coronary artery calcification in order to provide theoretical and clinical basis for the prevention and treatment of coronary artery calcification.Methods Ninety hundred and eighty-three cases were selected as our subjects who were hospitalized in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from Jan.2010 to Jul.2010 and undergone dual source CT coronary angiography.Of them,419 cases were male(male group),and 564 female (female group).The general information,clinical and biochemical indexes and coronary CTA results were collected.The patients were divided according to the BML Multivariate logistic regression analysis was applied to analyzed the relationship between BMI and coronary artery calcification,and multiple linear regression analysis was applied to analyzed the relationship between coronary artery calcification and BMI.Results There were significant differences between male group and female group in terms of age,height,body mass,BMI,smoking history,glomerular filtration rate (eGFR),triglyceride (TG),high density lipoprotein (HDL-C),left ventricular ejection fraction (LVEF),serum calcium,with peripheral vascular disease,as well as the baseline drugs,angiotensin converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB),calcium antagonists (CCB),statins compared the differences were statistically significant (P < 0.05).The rate of slight coronary artery calcification in male group and female groups were not statistically significant(x2 =0.714,P =0.398),while the rate of no calcification,severe calcification were statistically significant (P < 0.05).Multivariate Logistic regression analysis showed that high BMI(regression coefficient was-1.670,OR =0.967,95% CI =0.953 ~ 0.980,P =0.005),age (regression coefficient was 1.422,OR =4.416,95% CI1.015 ~ 16.927,P =0.001),history of hypertension (regression coefficient was 0.128,OR =1.521,95% CI1.262 ~ 1.830,P =0.002),history of diabetes mellitus (regression coefficient was 0.364,OR =1.439,95 % CI1.098 ~ 1.885,P =0.008),eGFR (regression coefficient was-0.5420,OR =0.004,95% CI0.001-0.019,P =0.014),LVEF (regression coefficient was-1.153,OR =0.316,95% CI0.127-0.787,P =0.002) and statins(regression coefficient was-6.745,OR0.323,95% CI0.138-0.754,P =0.032) were correlated with coronary artery calcification.Multiple stepwise linear regression analysis showed that only eGFR(r =0.79,95% CI0.69-0.92,P =0.001) was in the equation.Conclusion High BMI is a protective factor for severe coronary artery calcification,but there is on linear correlation between BMI and moderate to severe coronary artery calcification score in patients.
