Lipoprotein-associated phospholipase A2 during the hyperacute stage of ischemic and hemorrhagic strokes.

Abstract : The objectives of the study were to compare lipoprotein-associated phospholipase A2 (Lp-PLA2) levels in a prospective cohort including both ischemic and hemorrhagic strokes at the hyperacute phase, and to investigate if these levels were associated with stroke severity. Lp-PLA2 mass and activity were measured during the first 6 hours of symptom onset before any therapeutic intervention. The Lp-PLA2 level was analyzed by comparing the mass and activities in ischemic strokes and spontaneous intracerebral hemorrhages (ICH). Correlations between Lp-PLA2 levels and clinical scores as well as stroke volumes were made. The temporal evolution of Lp-PLA2 during the first week was analyzed in ischemic stroke patients. Lp-PLA2 mass was higher in ICH than in ischemic stroke (P = .001). Lp-PLA2 activity at admission correlated with initial and follow-up stroke volume in ICH (P = .003 and P = .004, respectively) but not in ischemic stroke. None of the measurements correlated with clinical severity for either diagnosis. Lp-PLA2 mass decreased during the first week after the use of statins in ischemic stroke, whereas the activity remained stable. Lp-PLA2 mass is higher in ICH compared with ischemic stroke during the hyperacute stage. Lp-PLA2 activity is associated with stroke volume in ICH but not in ischemic stroke. This suggests that Lp-PLA2 mass and activity could provide different information in the hyperacute stage of stroke.
