Diabetic dyslipidaemia: effective management reduces cardiovascular risk.
Patients with diabetes are at significantly increased risk for coronary heart disease (CHD); even those patients without a history of a previous myocardial infarction (MI) have as high a risk of a fatal or nonfatal MI as nondiabetic patients with a history of previous MI. As a result it is now generally recommended that cardiovascular risk factors be treated as aggressively in patients with diabetes as in nondiabetic patients with a history of CHD. Results from the recently published Collaborative Atorvastatin Diabetes Study (CARDS) and meta-analysis of primary and secondary interventions trials confirm that there is a uniform relative risk reduction across a wide range of high-risk patients including diabetes patients without established CHD. A highly significant 22-24% reduction in risk of future vascular events is evident when patients with diabetes are treated with statins in trials. Current guidelines, including the recently updated National Cholesterol Education Program (NCEP) guidelines, endorse aggressive, early intervention in very-high-risk patients, such as those with diabetes plus cardiovascular disease (CVD), regardless of baseline low-density lipoprotein cholesterol (LDL-C) level in order to achieve an LDL-C goal of 70 mg/dL (1.8 mmol/L). However, despite increasing evidence and knowledge of the value of lipid lowering, a recent survey of diabetes specialists indicates that many patients with diabetes remain untreated or undertreated. The availability of more effective statins should help to close this "action gap", in concert with other measures such as initiatives to improve patient compliance.
