Abstract:Objective To investigate the changes of serum ischemia-modified albumin (IMA) and lipoproteinassociated phospholipase A2 (LP-PLA2) levels in patients with acute cerebral infarction (ACI), and to analyze the correlation between the levels of both IMA and LP-PLA2 and the disease. Methods Totaly 122 patients with ACI diagnosed in our hospital were selected as the observation group from June 2017 to December 2018. According to the infarct area, 122 patients in the observation group were divided into three subgroups: minor infarct group (n = 35), medium infarct group (n = 57) and severe infarct group (n = 30). 62 healthy persons were selected as the control group in the same period. The serum levels of IMA and LP-PLA2 were detected. Pearson correlation analysis was used to observe the correlation between serum IMA, LP-PLA2 and the disease. Results The levels of serum IMA and LPPLA2 in the observation group were higher than those in the control group (P < 0.05). The levels of serum IMA and LP-PLA2 in the severe and medium group were higher than those in the minor group (P < 0.05). The levels of serum IMA and LP-PLA2 in severe group was higher than that in medium group (P < 0.05). Pearson correlation analysis showed that there was a positive correlation between serum IMA level and NIHSS score (r = 0.738, P = 0.000). There was a positive correlation between serum LP-PLA2 level and NIHSS score (r = 0.671, P = 0.000). Conclusion The levels of serum IMA and LP-PLA2 in ACI patients increase. The levels of serum IMA and LP-PLA2 were higher and positively correlated with the increase of infarct area. The serum levels of IMA and LP-PLA2 can be used as markers to judge the condition of ACI.
