Primary Outcome Measures:
  • HbA1c and results of meal tolerance test [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]
    Patient who was diagnosed with DM after an OGTT was asked to follow up HbA1c after 6-12 months. Acarbose was given for those who had HbA1c > 6.5%. After 26 weeks, sitagliptin was given for those who had HbA1c > 7.0%.

Secondary Outcome Measures:
  • Hypoglycemia [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]
    Symptoms of hypoglycemia or glucose value below 70 mg/dl after treatment with acarbose

Estimated Enrollment: 25
Study Start Date: April 2009
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Acarbose for DM patient with HbA1c > 6.5%. Add on sitagliptin if HbA1c > 7.0% after 26 weeks.
Drug: Acarbose
Acarbose 25 mg tid, titrate to 100 mg tid.
Other Name: Glucobay

Detailed Description:

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. Patients who were diagnosed as new DM would be asked to follow up after 6-12 months with diet control. Treatment with oral anti-diabetic drug may be needed if HbA1c target was not reached.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient received CAG or MDCT for suspect CAD
