Lipid-Lowering Therapy Use When Indicated and Subsequent Ischemic Stroke Severity.

Background: Elevated low-density lipoprotein cholesterol is a risk factor for atherosclerotic cardiovascular disease, including acute ischemic stroke (AIS), due to large- and small-vessel disease. Cholesterol management guidelines recommend lipid-lowering therapy (LLT) to prevent atherosclerotic cardiovascular disease events. This study assessed use of LLT at the time of AIS according to guideline recommendations and determined the association of prestroke LLT use with stroke severity.
