Primary Outcome Measures:
  • sudden cardiac death, fatal or non-fatal myocardial infarction, coronary revascularization, admission due to heart failure, fatal or non-fatal stroke [ Time Frame: one year ]

Estimated Enrollment: 150
Study Start Date: April 2009
Estimated Study Completion Date: March 2013
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Acarbose Drug: acarbose
50mg acarbose 3 times a day PO. duration: one year
Other Name: Glucobay

Detailed Description:
Acarbose suppresses the postprandial increase in plasma glucose levels by inhibiting the activities of alpha-amylase and alpha-glucosidase involved in digestion and absorption of carbohydrates in the intestine. A clinical study involving patients with type 2 diabetes demonstrated that acarbose decreased the post-load glucose level and improved glycosylated hemoglobin control. A prospective study involving patients with impaired glucose tolerance (IGT) demonstrated that acarbose inhibited progression to type 2 diabetes and significantly reduced the risk of cardiovascular diseases. It has also been reported that acarbose slows increase in the intima-media thickness and inhibits the progression of atherosclerosis. A significant proportion of patients with acute coronary syndrome and those with stable angina pectoris suffer from diabetes or IGT, and their prognosis is poor.
