Abstract

Abstract: Objective: To investigate the prevalence of coronary artery disease (CAD) and related risk factors in residents aged 40 to 60 years at Songnan District, Shanghai. Methods: Community residents without symptoms of CAD and aged 40 to 60 years at Songnan District, Shanghai were randomly selected and categorized into normal blood glucose group, pre-diabetes group and type 2 diabetes diagnosed within 5 years group. Questionnaires was performed to collect information on health status, medical history and lifestyle. Subjects received physical checkup including height, body weight, waist circumference, and blood pressure measurement, then oral glucose tolerance test and coronary computed tomography angiography (CCTA) were conducted. Significant coronary stenosis was defined as ≥50% narrowing of vessel lumen. Coronary artery calcification was defined to be present if coronary calcification score >0. Results: In the study population, 233 (42.4%) were males. Altogether 51.4%, 10.7% and 14.8% subjects were diagnosed as having coronary stenosis, significant coronary stenosis and coronary calcification, respectively. By multivariate analyses, the presence of CAD was significantly associated with male, age ≥53 years, hypertension, and diabetes. Conclusions: The prevalence of coronary stenosis, significant coronary stenosis, and coronary calcification are 51.4%, 10.7% and 14.8% in the study population, respectively. Male, age ≥53 years, hypertension, and diabetes are independent risk factors for CAD.
