Shanghai Jiao Tong University School of Medicine600 enrolled

Overview

Part I: Survey of Coronary Artery Calcification and Stenosis in Participants with Different Glycaemic Status Aims: To evaluate coronary artery calcification and stenosis in community-dwelling adults with different glycaemic status, using dual-source CT angiography (CTA) Study Subjects and Methods: 200 adults with normal glucose regulation (NGR), 200 with impaired glucose regulation (IGR) and 200 with type 2 diabetes were recruited from an urban community of Shanghai, who then underwent a comprehensive examination including questionnaire, anthropometric measurements, biochemical analysis and CTA. Part II: Follow-up of Cardiovascular Events and Re-evaluation of Coronary Artery Calcification and Stenosis Aims and Methods: To investigate the development of cardiovascular diseases in subjects recruited in part I and re-evaluate coronary artery calcification and stenosis using CTA after 3-year follow-up To identify the predictive value of coronary artery calcification and stenosis with future risks of cardiovascular diseases and the possible development of coronary artery disorders among participants with different glycaemic status

Outcomes

Primary Outcomes

Number of participants who will develop cardiovascular events during follow-up

Cardiovascular events include non-fatal myocardial infarction, non-fatal stroke and cardiovascular death. The progression of coronary artery calcium and stenosis is also evaluated at the final visit.
