Interventions/Control_1 For Type 2 diabetic patients (HbA1c level: 6.5%-9.0%) with acute coronary syndrome, who had undergone coronary intervention with bare metal stent (Liberte; Coronary Stent System), Sitagliptin Phosphate Hydrate (DPP-4 Inhibitor) is initiated at a dose of 50mg per day post stenting and titrated up as needed to 100mg per day to reach the target level of HbA1c within 6.5%. Major Adverse Cardiac and Cerebrovascular Events (MACCE) at 8 months will be estimated. Estimation of arteriosclerosis is examined at baseline and at 8 months by imaging diagnostics modalities (coronary angiography, IVUS, OCT, and carotid vascular echography).
Interventions/Control_2 For Type 2 diabetic patients (HbA1c level: 6.5%-9.0%) with acute coronary syndrome, who had undergone coronary intervention with bare metal stent (Liberte; Coronary Stent System), conventional antidiabetic agent is initiated to reach the target level of HbA1c within 6.5%. Major Adverse Cardiac and Cerebrovascular Events (MACCE) at 8 months will be estimated. Estimation of arteriosclerosis is examined at baseline and at 8 months by imaging diagnostics modalities (coronary angiography, IVUS, OCT, and carotid vascular echography).
