Title: Bypass Angioplasty Revascularization Investigation in Type 2 Diabetes
Brief Summary: The BARI 2D trial is a multicenter study that uses a 2x2 factorial design, with 2400 patients being assigned at random to initial elective revascularization with aggressive medical therapy or aggressive medical therapy alone with equal probability, and simultaneously being assigned at random to an insulin providing or insulin sensitizing strategy of glycemic control (with a target value for HbA1c of less than 7.0% for all patients).

SPECIFIC AIMS

A. Primary Aim

The primary aim of the BARI 2D trial is to test the following two hypotheses of treatment efficacy in 2400 patients with Type 2 diabetes mellitus and documented stable CAD, in the setting of uniform glycemic control and intensive management of all other risk factors including dyslipidemia, hypertension, smoking, and obesity:

1. Coronary Revascularization Hypothesis: a strategy of initial elective revascularization of choice (surgical or catheter-based) combined with aggressive medical therapy results in lower 5-year mortality compared to a strategy of aggressive medical therapy alone;
2. Method of Glycemic Control Hypothesis: with a target HbA1c level of less than 7.0%, a strategy of hyperglycemia management directed at insulin sensitization results in lower 5-year mortality compared to a strategy of insulin provision.

B. Secondary Aims

The secondary aims of the BARI 2D trial include: a) comparing the death, myocardial infarction or stroke combined endpoint event rate between the revascularization versus medical therapy groups and between the insulin sensitization versus insulin provision groups; b) comparing rates of myocardial infarction, other ischemic events, angina and quality of life associated with each revascularization and hyperglycemia management strategy; c) evaluating the relative economic costs associated with the trial treatment strategies, d) exploring the effect of glycemic control strategy on the progression and mechanism of vasculopathy including changes in PAI-1 gene expression.

Patients with Type 2 diabetes mellitus and CAD documented by coronary arteriography will be eligible for the trial if revascularization is not required for prompt control of severe or unstable angina. Diabetic patients who are being treated with insulin or oral hypoglycemic drugs will be eligible as well as diabetic patients treated with diet and exercise alone provided that a diagnosis of diabetes can be confirmed by record review or that a fasting plasma glucose (FPG) greater than 125/mg/dL (7.0 mmol/L) can be obtained. The determination of suitability for BARI 2D will be made by a physician-investigator at each participating institution on clinical grounds at the time of coronary angiography.

Significant CAD will be defined as at least one stenosis greater than 50%. Angina and ischemia will be assessed by use of patient self-report, physician examination, and appropriate diagnostic measures including exercise myocardial perfusion imaging, exercise echocardiography, exercise electrocardiography, and IV dipyridamole or adenosine myocardial perfusion imaging or invasively by doppler or pressure wire. Objective documentation of myocardial ischemia includes any of the following:

1. Exercise or pharmacologically-induced:

   1. Greater than or equal to 1 mm of horizontal or downsloping ST depression or elevation for greater than or equal to 60-80 milliseconds after the end of the QRS complex
   2. Myocardial perfusion defect
   3. Myocardial wall motion abnormality
2. Stabilized, prior acute coronary syndrome with CK-MB or troponin elevation or with new, greater than or equal to 0.5 mm ST depression or elevation, or T wave inversion of greater than or equal to 3 mm in 2 contiguous ECG leads
3. Doppler or pressure wire showing coronary flow reserve (CFR) less than 2.0 or fractional flow reserve (FFR) less than 0.75

Among patients without documented ischemia, only patients with stenosis greater than or equal to 70% presenting with classic anginal symptoms will be eligible for randomization.
