Abstract:
Objective To investigate the predictive value of plasma lipoprotein associated phospholipase A 2 (Lp-PLA2 ) in cere-bral infarction(CI) after transient cerebral ischemia attack (TIA).Methods Plasma Lp-PLA2 level was detected in 112 TIA pa-tients ,and the incidence rate of CI was observed on 7 ,30 ,90 d after TIA.Then the grouping was performed according to the Lp-PLA2 level ,and the predictive value of Lp-PLA2 in the risk of CI occurrence after TIA was evaluated.Results Among 112 patients with TIA ,27 cases (24.1% ) developed CI within 90 d;there were 17 cases(63.0% ) of CI after TIA in the Lp-PLA2 >207 μg/L group ,which were significantly higher than that in the 175-207 μg/L group and <175 μg/L group (P<0.05);moreover the CI occurrence in TIA patients was mainly concentrated within 7 d after onset ;the patients of Lp-PLA2 ≥175μg/L were mainly distrib-uted in the moderate and high risk groups of ABCD2 score system ;in ROC curve of Lp-PLA2 for predicting CI after TIA ,with Lp-PLA2 ≥194 μg/L as the diagnostic critical point ,the sensitivity was 0.730 and specificity was 0.680.Conclusion Lp-PLA2 may be an effective risk predictive indicator of CI occurrence after TIA ,and can improve the adverse outcome of TIA patients.
