The diagnostic and prognostic performance of Lp-PLA2 in acute ischemic stroke

Abstract Objective We aimed to investigate the correlation between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) level and acute ischemic stroke (AIS) severity and recurrence, which could indicate the diagnostic and prognostic values of Lp-PLA2. Methods Two hundred and fifty-one AIS patients who were diagnosed in the department of neurology, China-Japan Union Hospital, from April 2018 to June 2019 and 100 non-cerebrovascular disease patients were included in this study. Demographic data and clinical materials including age, sex, BMI, medical history, bad habits, imaging data, blood tests, etc., were collected. Stroke severity and risk were evaluated, respectively. AIS patients were followed up for 6 months for stroke recurrence monitoring. Results The AIS group had significantly higher Lp-PLA2 level than the control group. High Lp-PLA2 level was the independent risk factor of AIS (OR 1.010; 95% CI 1.007–1.013, P  Conclusion High serum Lp-PLA2 level is correlated with AIS incidence, disease severity and recurrence, which could be utilized to guide clinical practice.
