Role of Rosiglitazone on Pre-Diabetes Mellitus and Coronary Artery Disease
The investigators examined whether rosiglitazone, a thiazolidinedione (TZD), is beneficial for pre-diabetes mellitus (DM) adults with documented coronary artery disease (CAD).
Microvascular and macrovascular complications are common in type 2 DM. There is no evidence about the effects of TZDs, synthetic peroxisome proliferator-activated receptor (PPAR)-γ activators (insulin sensitizers and adipose transcriptional regulation and anti-inflammatory process activators) on pre-DM patients with documented CAD.
|Prediabetes Coronary Artery Disease Insulin Resistance Glucose Intolerance||Drug: placebo tablet Drug: rosiglitazone (4 mg)/day||Phase 3|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||Role of Rosiglitazone Treatment and Secondary Prevention of Cardiovascular Events in Patients With Pre-Diabetes Mellitus and Coronary Artery Disease|
- major cardiovascular events, including myocardial infarction, overt heart failure, and surgery or coronary intervention for CAD [ Time Frame: at least 6 months follow-up of MACEs ]Primary end points: The primary end-point was defined as major cardiovascular events, including myocardial infarction, overt heart failure, and surgery or coronary intervention for CAD.
- Biomarkers measurements [ Time Frame: Biomarkers were taken before the trial and 6 months later ]
Resistin and adiponectin will be measured to evaluate insulin resistance; CCL/MCP-1 and hsCRP were also analyzed to evaluate inflammation status changes.
Several vascular associated remodeling markers and proteins will also be measured.

|Placebo Comparator: placebo||
Drug: placebo tablet
placebo tablet for 6 months
|Experimental: rosiglitazone (4 mg)/day||
Drug: rosiglitazone (4 mg)/day
rosiglitazone (4 mg)/day for 6 months
Materials and Methods:
This is a randomized, double-blind, placebo-controlled study, patients will be randomly assigned to the TZD group and to the placebo group with a 6-month treatment period.
Biomarkers will also examined before and 6 months post-treatment during the trial.
The primary end-points will be the diagnosis of major cardiovascular events: myocardial infarction, overt heart failure, and surgery or coronary intervention for CAD.
