BackgroundLow-density lipoprotein (LDL) cholesterol has been long associated with the risk for ischemic stroke, myocardial infarction, and cardiovascular death. For more than a decade, the main pharmacological option to prevent stroke and myocardial infarction through LDL-cholesterol lowering was the use of statins. During the recent years, two novel classes of drugs have proven their efficacy and safety to reduce LDL-cholesterol and prevent cardiovascular events in large, well-conducted randomized controlled trials: ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors.AimsThe present review summarizes the evidence arising from the latest trials of lipid-lowering treatment for cardiovascular outcomes prevention and discusses their implications for secondary prevention strategies in patients with ischemic stroke.Summary Of ReviewThere is strong evidence which confirms the hypothesis that the lower the LDL-cholesterol, the less frequent the cardiovascular events are and underlines the importance of treating our ischemic stroke patients with intensive statin treatment aiming at low LDL-cholesterol levels. The very low levels of LDL cholesterol seem to be safe, even in the mid/long term but longer follow-up data are needed. Currently there are no tools to reliably predict cardiovascular outcomes in the specific population of ischemic stroke patients.ConclusionsStroke physicians should aim for low LDL-cholesterol levels by intensive statin treatment in all ischemic stroke patients. For those patients who are at the highest risk for recurrent stroke or another cardiovascular event and have unacceptable LDL-cholesterol levels despite intensive statin treatment, PCSK9 inhibitors should be considered.
