PLA2G7 and transient ischemic attack: One included study indicated that Lp-PLA2 mass levels were associated with the risk of atherosclerotic stroke among non-Hispanic white participants,[24] whereas other studies have shown that Lp-PLA2 activity levels were increased significantly when considering a large-artery atherosclerotic (LAA) etiology as the most likely mechanism for the TIA incidence.[26] It is tempting to speculate that due to the limited outcomes recorded, there is insufficient specific evidence regarding the relationship between Lp-PLA2 levels and the etiological classifications of ischemic stroke.
