  ABSTRACT: Diabetes is increasing rapidly worldwide and frequently results in severe vascular complications. A target glycated hemoglobin of less than 7% has commonly been recommended in hopes of preventing both macrovascular and microvascular complications. Although results from trials of intensive glycemic control have generally supported the notion that lower glycated hemoglobin values reduce microvascular disease, the evidence for similar benefits for macrovascular disease has been less clear. As macrovascular disease is the major cause of morbidity and mortality in type 2 diabetes, this remains one of the more important unresolved clinical questions. Recent results from the ACCORD, ADVANCE, and VADT studies have challenged the conventional believe that lower glycated hemoglobin values should be pursued in all diabetic patients. Factors that may influence whether intensive glucose management is advisable include duration of diabetes, pre-existing macrovascular disease, hypoglycemic unawareness, and significant comorbidities. Glycated hemoglobin goals should account for these factors and be individualized for each patient.

  ABSTRACT: Cardiovascular disease (CVD) is the major cause of morbidity and mortality in patients with type 2 diabetes mellitus (T2DM). Recent major publications, such as the Action to Control Cardiovascular Risk in Diabetes trial, the Advance in Diabetes and Vascular Disease: Preterax and Diamicron MR Controlled Evaluation trial, and the Veterans Affairs Diabetes Trial, found that intensive glucose control in patients with T2DM did not reduce CVD outcomes. However, in this article, we review observational studies and clinical trials that, on aggregate, indicate how glucose lowering appears to reduce risks of CVD in certain subgroups, but can be harmful in other individuals. Based on available evidence, we suggest that younger patients with a shorter duration of T2DM, without CVD, and with few comorbid conditions may experience the greatest cardiovascular benefit from intensive glucose control. In contrast, more aggressive glucose lowering in older patients with a longer duration of T2DM, a history of CVD, and/or multiple comorbidities does not translate to reduced cardiovascular events, and may cause harm. The target goal and therapeutic strategy for intensive glucose control should be established for each individual after a careful review of his or her medical and psychosocial history, and should not reflect a "one-size-fits-all" approach.
