Introduction: Proper lipid management is vital for secondary prevention of ischemic stroke; however, not a few patients fail to reach target low-density lipoprotein cholesterol (LDL-C) levels with statin monotherapy. This study aimed provide real-world data on LDL-C achievement using rosuvastatin plus ezetimibe combination therapy (R+E) in stroke who did achieve an level <70 mg/dL statins alone. Methods: multicenter, prospective, observational enrolled adult baseline ≥70 monotherapy from...
