LDL Subclasses in Ischemic Stroke: A Risk Factor?

INTRODUCTION: Seven low-density lipoprotein (LDL) subclasses are identified, and smaller LDL particles are associated with an increased risk for cardiovascular events. However, there is limited data about the relationship between the acute ischemic stroke (AIS) subtypes and LDL subclasses. The aim of our study is to investigate the relationship between AIS subtypes and LDL subclasses. METHODS: This study consisted of 110 AIS patients and 60 healthy controls. Stroke patients were classified according to the TOAST classification system as cardioembolic infarct (CI), large artery atherosclerosis (LAA), and lacunar infarct (LI). LDL subclasses were distributed as seven bands (LDL-1 and-2 defined as large, and LDL-3 to-7 defined as small-LDL particle), using the LipoPrintª System. Control group and AIS subtypes were compared in terms of LDL subclasses; p
