Statins reduce both LDL cholesterol (LDL-C) levels and the risk of cardiovascular events in patients with and without cardiovascular disease. Intensive statin therapy, compared with moderate-dose statin therapy, incrementally lowers LDL-C levels and rates of cardiovascular events in patients presenting with acute coronary syndrome. Ezetimibe, by diminishing the absorption of cholesterol from the intestine, additionally reduces LDL-C when added to statins. In this article, we discuss the potential benefits of the combination of simvastatin and ezetimibe for the long-term management of patients with acute coronary syndrome through an analysis of the IMPROVE-IT results (IMProved Reduction of Outcomes: Vytorin Efficacy International Trial). This randomised double blind trial included 18,144 patients with a LDL-C of 50 to 100 (with statin) or 125 (without statin) mg/dl and had a median follow-up of 6 years. The objective of the study was to test the efficacy of simvastatin 40 mg versus simvastatin 40 mg and 10 mg ezetimibe. The primary endpoint included cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina and coronary revascularization. The addition of ezetimibe to simvastatin resulted in an incremental lowering of LDL-C (reached value 53.2 versus 69.9 mg/dl, p < 0.001) and a further improvement of the patient prognosis (relative reduction of primary endpoint: -6.4%, p = 0.016). In addition, the combined therapy showed no significant adverse effects, particularly regarding the risk of cancers, which confirms the safety of ezetimibe. In acute coronary syndrome, the prescription of ezetimibe should be considered (class HA, level of evidence B) in patients with a LDL-C a 70 mg/dl despite maximally tolerated dose of statin.
