ABSTRACT
AIMS: This study aims to compare the preventive effect of low- or moderate-statin with ezetimibe combination therapy and high-intensity statin monotherapy on cardiovascular disease (CVD) and all-cause death in a real-world setting. METHODS AND RESULTS: Using the Korean National Health Insurance Service datasets, two cohorts comparing high-intensity statin monotherapy with low- or moderate-intensity statin and ezetimibe combination were constructed by 1:1 propensity score matching procedure. Primary outcome was a composite of myocardial infarction (MI), stroke, and all-cause death. Secondary outcome was an individual event. The study population was followed from baseline until the date of events, or the last health check-ups, whichever came first. Compared to high-intensity statin monotherapy, moderate-intensity statin with ezetimibe combination significantly reduced the risk of composite outcome [hazard ratio (HR) 0.84, 95% confidence interval (CI) 0.77-0.92, P < 0.001] as well as individual MI (HR 0.81, 95% CI 0.71-0.94, P = 0.005) and stroke (HR 0.78, 95% CI 0.65-0.93, P = 0.005), but not all-cause death. Low-intensity statin with ezetimibe also significantly reduced the risk of the composite outcomes (HR 0.80, 95% CI 0.66-0.97, P = 0.024) compared to high-intensity statin monotherapy, but the risk of individual outcome did not differ between two groups. Statin and ezetimibe combination demonstrated consistent effect across various subgroups. CONCLUSION: Among people without pre-existing CVD, moderate-intensity statin with ezetimibe combination was superior to high-intensity statin monotherapy in preventing composite outcomes as well as each of MI and stroke. In contrast, low-intensity statin with ezetimibe combination reduced the risk of composite but not individual outcomes.
We compared the preventive effect of low- or moderate-statin with ezetimibe combination and high-intensity statin monotherapy on cardiovascular disease and all-cause death. Low- or moderate-intensity statin with ezetimibe is beneficial for reducing a composite of myocardial infarction (MI), stroke, and all-cause death. Moderate-intensity statin with ezetimibe reduced 19% of MI and 22% of stroke, compared with high-intensity statin. Statin with ezetimibe combination might be attractive bypass for primary prevention, beyond an alternative to high-intensity statin.

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 ± 37.9â mg/dL vs 80.8 ± 38.8â 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.
