[Association of serum lipoprotein-associated phospholipase A2 with vascular dementia after ischemic stroke].

Abstract

Objective: To study the relationship of serum lipoprotein-associated phospholipase A2 (Lp-PLA2) with vascular dementia (VD) after ischemic stroke. Methods: A total of 226 ischemic stroke patients who visited the People's Hospital of Zhengzhou University from June.2013 to Oct.2016 were included and divided into the VD group and the non-dementia group according to the degree of cognitive impairment.The non-dementia group were further divided into the normal cognition group and the vascular cognitive impairment no dementia(VCIND) group.The general information of all patients were collected and the serum Lp-PLA2, Hcy, hs-CRP and the blood lipid indexes were detected.The Logistic regression model was built to analyze the association of Lp-PLA2 with the VD, correlation analysis and ROC curve were conducted to analyze the correlation of Lp-PLA2 with the state of cognitive impairment and to generate the cutoff value respectively. Results: The serum Lp-PLA2 in VD group[(221±84) ng/ml] was significant higher than the non-dementia group[(133±60) ng/ml], the Lp-PLA2 in VCIND group[(148±65) ng/ml] was significant higher than the normal cognition group[(114±48) ng/ml](P<0.05). The result of Logistic regression showed that Lp-PLA2 was a significant risk factor of VD[(OR(95%CI)=1.015(1.010-1.021)], and its level was negatively correlated with the score of cognitive function.The cutoff value of Lp-PLA2 between the VD and non-dementia was 164.65 ng/ml and was 120.8 ng/ml between the normal cognition group and VCIND group. Conclusion: Lp-PLA2 is a significant risk factor of VD after ischemic stroke.
