Diabetes and other coronary heart disease risk equivalents.

The close association between diabetes and cardiovascular disease suggests that current predictions of a massive increase in the prevalence of type 2 diabetes foreshadow an equally daunting rise in the incidence of vascular disease. The limited cardiovascular benefits obtained by glucose-lowering treatments, although perhaps not surprising, indicate that other cardiovascular risk factors must be given serious consideration as therapeutic targets. The impressive reductions in the number of vascular events observed in diabetic patients, albeit in small patient populations, participating in various drug trials amply justify such an approach. A necessary prerequisite, however, is a clear understanding of the clinical importance of individual risk factors to the occurrence of vascular disease in type 2 diabetic patients. This would appear essential for defining treatment strategies in the face of a bewildering array of potential therapeutic targets. The present review considers recent studies that have assessed the predictive value of risk factors against a diabetic background.
