Screen of DM by OGTT in Subjects Receiving CAG or MDCT for CAD

It had been reported that high prevalence of IGT (impaired glucose tolerance) and unknown DM (diabetes mellitus) in patients with CAD (coronary artery disease). This study aimed to determine the glucose regulation status of patients who were suspected to have CAD in central Taiwan. In general, patient who were admitted for CAG (coronary angiography) or MDCT without known DM were eligible. After informed consent, OGTT (oral glucose tolerance test) was performed to determine the glucose regulation status. Study participants will be requested to complete questionnaires to assess their risk of diabetes and quality of sleep. Patients who were diagnosed as new DM would be asked to follow up in clinical service with diet control.
