Objective: To review relevant literature supporting the need for intensive lipid management in patients with diabetes mellitus. Data Sources: A literature search using MEDLINE (1975–March 2005) was conducted. The search terms coronary disease, diabetes mellitus, hydroxymethylglutaryl-coenzyme A reductase inhibitors (statins), lipoproteins, and low-density lipoprotein cholesterol (LDL-C) were used to identify published trials comparing the effects of intensive LDL-C lowering and cardiovascular morbidity and mortality. Study Selection and Data Extraction: Primary literature was evaluated and included in this review if the study was a large randomized trial containing a significant number of diabetic patients receiving primary prevention. For trials including patients without diabetes, an available sub-analysis of the diabetic population in that trial must have been available. Data Synthesis: The incidence of diabetes mellitus is rising in dramatic proportions throughout the nation. In addition to the diagnosis of diabetes, many of these patients also have preexisting risk factors that increase their risk for cardiovascular morbidity and mortality. In 2004, the National Cholesterol Education Program issued a scientific statement proposing a newer and lower optimal LDL-C goal for high-risk populations. This article reviews pertinent findings from recent clinical trials and guidelines discussing the need to integrate more stringent LDL-C goals into clinical practice. Conclusions: Although data are limited, all patients with diabetes mellitus, regardless of cardiovascular status, may benefit from lipid-lowering therapy with an optimal LDL-C goal of < 70 mg/dL.
