OBJECTIVE -To examine lipid management trends for coronary artery disease (CAD) patients with and without diabetes in order to determine whether those with diabetes are beginning to receive aggressive lipid management consistent with their elevated risk.RESEARCH DESIGN AND METHODS -We used outpatient medical record data from 47,813 CAD patients seen at 295 medical practices participating in the Quality Assurance Program II between 1996 and 1998. Lipid testing rates, lipid treatment rates, and serum lipid concentrations are described for CAD patients with and without diabetes within strata of office visit date.RESULTS -Lipid testing and treatment rates increased and mean lipid levels decreased markedly over time. Those with diabetes were 26% less likely to have a lipid profile and 17% less likely to receive a lipid-lowering medication than their nondiabetic counterparts, and this disparity did not diminish over time. Among treated patients, mean non-HDL cholesterol (non-HDL-C) and LDL cholesterol (LDL-C) declined less rapidly over time for patients with than without diabetes.CONCLUSIONS -Although impressive progress was made in the outpatient lipid management of CAD patients, lipid management for CAD patients with diabetes improved no more rapidly, and in some cases less rapidly, than for nondiabetic patients. Given their higher risk, more effort is needed to ensure that CAD patients with diabetes receive aggressive lipid management.
Diabetes Care 26:991-997, 2003T he increased risk of cardiovascular events associated with diabetes is well established (1-6). In a recent report from a Finnish cohort, Haffner et al. (2) demonstrate that diabetic patients without a prior myocardial infarction (MI) had approximately the same 7-year incidence of MI (ϳ20%) as nondiabetic patients with a prior MI (2). This finding is consistent with a recent report of patients hospitalized with unstable angina or non-Q-wave MI showing that the 2-year event rate for diabetic patients without prior coronary artery disease (CAD) was similar to that of nondiabetic patients with prior CAD (3). Another important finding from both studies, and one especially relevant for this report, is that the incidence of new MI among diabetic patients with a prior MI is more than twice that of patients with either prior MI or diabetes alone. Others have demonstrated that CAD patients with diabetes are more likely to die following an MI than their nondiabetic counterparts (4 -6).Thus, a multitude of clinical and epidemiological evidence indicates that individuals with both CAD and diabetes are at an exceptionally high risk for new cardiovascular events and mortality compared with those with either CAD or diabetes alone (1-10). Patients with combined CAD and diabetes represent one of the highest risk populations commonly seen by physicians in the outpatient setting.Although at high risk for future cardiovascular events, individuals with CAD and diabetes are as likely as those without diabetes to benefit from 3-hydroxy-3-methylglutaryl coenzyme A reductase in...
