Low-density lipoprotein cholesterol reduction and goal achievement with ezetimibe/simvastatin versus atorvastatin or rosuvastatin in patients with diabetes, metabolic syndrome, or neither disease, stratified by National Cholesterol Education Program risk category.
BACKGROUND
Patients with diabetes mellitus (DM) and metabolic syndrome are at increased risk of coronary heart disease (CHD). Studies have shown differential statin efficacy on low-density lipid cholesterol (LDL-C) by CHD risk strata.


OBJECTIVE
The aim of this study was to evaluate the consistency of effect with ezetimibe/simvastatin (E/S) combination therapy, atorvastatin, or rosuvastatin in patients with DM, metabolic syndrome, or neither condition (No DM/metabolic syndrome), stratified by the National Cholesterol Education Panel Adult Treatment Panel III (NCEP ATP III) CHD risk group.


METHODS
Post hoc analyses of 2 multicenter, double-blind, randomized, 6-week studies comparing E/S 10/10, 10/20, 10/40, or 10/80 mg with either atorvastatin 10, 20, 40, or 80 mg, or rosuvastatin 10, 20, or 40 mg. Treatments were compared by pooling across all doses for LDL-C reduction and NCEP LDL-C goal attainment in patients with DM, metabolic syndrome without DM, or No DM/metabolic syndrome across NCEP CHD risk strata.


RESULTS
NCEP LDL-C goal attainment was lowest in the high-risk group with atherosclerotic vascular disease (12-64%) and greatest in the moderate and low-risk groups (84-100%). In contrast, LDL-C reduction was generally similar irrespective of disease or risk subgroup. All treatments were generally well tolerated, with overall similar safety regardless of disease and risk level.


CONCLUSIONS
In these studies, CHD risk strata were inversely related to the likelihood of attaining NCEP LDL-C goals, but did not appear to affect the percentage LDL-C change from baseline. This demonstrates the need for especially aggressive cholesterol lowering necessary to reach the lower LDL-C goal for high-risk patients.
