Brief Summary:

Objectives:

The investigators examined whether rosiglitazone, a thiazolidinedione (TZD), is beneficial for pre-diabetes mellitus (DM) adults with documented coronary artery disease (CAD).

Background:

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.


Condition or disease Intervention/treatment Phase
Prediabetes Coronary Artery Disease Insulin Resistance Glucose Intolerance Drug: placebo tablet Drug: rosiglitazone (4 mg)/day Phase 3

Detailed Description:

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.

Arm Intervention/treatment
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




Primary Outcome Measures :
  1. 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.


Secondary Outcome Measures :
  1. 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.
