Correlation Between Body Mass Index And Coronary Stenosis Severity Degree In Patients With Coronary Heart Disease And Diabetes

Objective:To investigate the correlation between body mass index and coronary stenosis severity degree in different groups.Methods:A total of 511 patients with coronary heart disease and diabetes received coronary angiography from October 2014 to September 2017 in the Affiliated Dayi Hospital of Shanxi Medical University were included in the analysis.They were divided into mild group(Gensini score<24.5),moderate group(24.5?Gensini score<68)and severe group(Gensini score?68)based on the Gensini score.Clinical characteristics and coronary stenosis severity degree were compared between three groups.Results:There were no significant associations between coronary stenosis and gender,age,total cholesterol,triglycerides,smoking,hypertension and diabetes duration.The associations between coronary stenosis and BMI was significant(P < 0.05).Compared with normal weight patients(BMI 18.5 to 23.9kg/m2,reference category),overweight patients(BMI 24 to 28kg/m2,OR = 1.800,95% CI: 1.205 ~ 2.691,P = 0.004<0.05)and obesity patients(BMI?28kg/m2,OR = 1.652,95% CI: 1.044 ~ 2.614,P = 0.032<0.05)had a significantly lower lesions.Smoking had a higher risk of serious lesions(OR =0.663,95% CI:0.475~0.925,P = 0.015<0.05).Conclusion:In patients with coronary heart disease and diabetes,the higher the BMI,the lower the coronary stenosis.Smoking had a higher risk of serious lesions.
