RESUMO
OBJECTIVE: To analyze the relationship between lipoprotein-associated phospholipase A2 (Lp-PLA2) and ischemic stroke.â© Methods: Corresponding data, with case-control studies or cohorts regarding Lp-PLA2 and ischemic stroke, were retrieved from PubMed, Web of Science, Embase, the Cochrane Library, Chinese Biomedical Literature (CMB), VIP, China National Knowledge Infrastructure (CNKI), and Wanfang Database. Meta-analysis was performed by using Stata12.0.â© Results: Eight studies including 46 034 participants met the inclusion criteria. Meta-analysis showed that the combined effect of relative risk (RR) between Lp-PLA2 mass and ischemic stroke was [1.04 (0.98 to 1.11)] and that the combined effect of RR between Lp-PLA2 activity and ischemic stroke was [1.03 (0.96 to 1.10)], suggesting that Lp-PLA2 mass and activity were not associated with ischemic stroke.â© Conclusion: It cannot be considered that Lp-PLA2 mass and Lp-PLA2 activity was the risk factor for ischemic stroke.
