Clinical Comparison of Low-dose Rosuvastatin Plus Ezetimibe Combination Therapy and High-dose Rosuvastatin Monotherapy in Patients With Minimal to Intermediate Coronary Artery Disease Without Percutaneous Coronary Intervention : A Prospective, Multicenter, Randomized, Open-label Trial
\[Purpose of the Clinical Study\]:The purpose of this study is to conduct a clinical comparison of low-dose rosuvastatin plus ezetimibe combination therapy and high-dose rosuvastatin monotherapy in patients with minimal to intermediate coronary artery disease without percutaneous coronary intervention to confirm non-inferiority in the reduction of key cardiovascular events. \[Hypothesis\]:In patients who have not undergone percutaneous coronary intervention for minimal to moderate coronary artery disease, low-dose rosuvastatin and ezetimibe combination therapy are non-inferior in terms of reducing major cardiovascular events compared to high-dose rosuvastatin monotherapy.
