Abstract
CONTEXT
Low-density lipoprotein cholesterol (LDL-C)-lowering therapy is considerably important in preventing cardiovascular disease (CVD) among patients with diabetes. Studies comparing CVD, stroke, and mortality outcomes of low- or moderate-intensity statins with ezetimibe combination therapy and high-intensity statin monotherapy in patients with diabetes remain lacking.
OBJECTIVE
This study compared the primary prevention effect of myocardial infarction (MI), stroke, and all-cause death between combination therapy of low- or moderate-intensity statins and ezetimibe and high-intensity statin monotherapy in patients with diabetes using the Korean National Health Insurance claims database.
METHODS
Patients aged ≥20 years with type 2 diabetes and dyslipidemia were enrolled. The combination therapy of low- or moderate-intensity statin and ezetimibe was compared with high-intensity statin monotherapy after a propensity score-matched analysis. The incidence of composite outcomes consisting of MI, stroke, and all-cause death and each component were analyzed.
RESULTS
In moderate-intensity statin therapy with ezetimibe combination therapy, LDL-C (74 ± 37.9 mg/dL vs 80.8 ± 38.8 mg/dL, P < .001) and the incidence of composite outcomes were lower (hazard ratio 0.85, 95% CI 0.74-0.98) than those in high-intensity statin monotherapy. Meanwhile, no significant difference was observed in the LDL-C levels and composite outcomes between low-intensity statins with ezetimibe combination therapy and high-intensity statin monotherapy.
CONCLUSION
Adding ezetimibe to a moderate-intensity statin in patients with type 2 diabetes has a greater LDL-C-lowering effect and greater primary prevention of composite outcomes than that of high-intensity statin monotherapy.
