A randomized trial of therapies for type 2 diabetes and coronary artery disease
BARI 2D Study Group et al. – Findings show no significant difference overall in rates of death and major cardiovascular events between pts undergoing prompt revascularization and those undergoing medical therapy or between strategies of insulin sensitization and insulin provision. Methods- Randomization of 2368 pts with both type 2 diabetes and heart disease to either prompt revascularization with intensive medical therapy or intensive medical therapy alone and to undergo either insulin-sensitization or insulin-provision therapy
- Primary endpoints: rate of death and composite of death, myocardial infarction, or stroke (major cardiovascular events)
- Randomization stratified by choice of percutaneous coronary intervention (PCI) or coronary-artery bypass grafting (CABG) as the more appropriate intervention
Results- At 5 yrs, rates of survival did not differ significantly between revascularization (88.3%) and medical-therapy group (87.8%) or between insulin-sensitization (88.2%) and insulin-provision group (87.9%)
- Rates of freedom from major cardiovascular events did not differ significantly among groups: 77.2% in revascularization vs 75.9% in medical-treatment group and 77.7% in insulin-sensitization vs 75.4% in insulin-provision group
- In PCI stratum, no significant difference in primary endpoints between revascularization vs medical-therapy group
- In CABG stratum, significantly lower rate of major cardiovascular events in revascularization (22.4%) vs medical-therapy group (30.5%) for interaction between stratum and study group
- Adverse events and serious adverse events generally similar among the groups
- Severe hypoglycemia more frequent in insulin-provision (9.2%) vs insulin-sensitization group (5.9%)
