- 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.
