ACCORD, ADVANCE, and VADT Background Study Design and Results Lessons Learned

ACCORD, ADVANCE, and VADT Lessons Learned Intensive glucose control does not reduce CVD mortality in T2DM, and may increase risk, especially in patients with pre-existing CHD Aggressive A1c targets (<6.5%) were associated with a 3-fold increased risk hypoglycemia No excess CVD Mortality was seen with Rosigliatazone

ACCORD, ADVANCE, and VADT Lessons Learned- Continued Intensive control associated with reduced risk for nephropathy in ADVANCE. To reach and maintain A1c targets of <6.5 required frequent adjustments of multiple anti- diabetic medications Aggressive Targets (<6.5) are probably reasonable for healthy patients to reduce risk micro-vascular complications

ADA Consensus Statement on Medical Management of Hyperglycemia in Type 2 Diabetes Achieve and Maintain near normoglycemia, A1c <7.0 Initiate Therapy with Lifestyle and Metformin Rapid addition of medications, and transition to new regimens when targets are not achieved Early addition of insulin therapy in patients who do not met target goals Nathan, Diabetes Care 2008;31:1-11
