| Abstract: | Objective To explore and analyze the relations between the activity level of plasma lipoprotein-associated phospholipase A2(Lp-PLA2)and unstable carotid atherosclerotic plaque in middle-aged or elderly patients with hypertension and corresponding clinical significance.Methods One hundred and two patients with hypertension were selected to undergo bilateral carotid ultrasound examinations and were divided into two groups including 50 cases in stable carotid atherosclerotic plaque and 52 cases in unstable carotid atherosclerotic plaque based on the comprehensive evaluation involving ultrasound images,plaque morphology and echo characteristics.The enzyme activity method was used to determine the activity level of plasma Lp-PLA2 in patients,and the influencing factors of unstable carotid atherosclerotic plaque and predictive value of activity level of plasma Lp-PLA2 on unstable carotid atherosclerotic plaque were analyzed.Results The activity level of plasma Lp-PLA2 activity in the patients in unstable carotid atherosclerotic plaque group was higher than that in in patients in the stable carotid atherosclerotic plaque group(P<0.05).The activity level of plasma Lp-PLA2 activity isserved as an independent risk factor affecting unstable carotid atherosclerotic plaque in middle-aged and or elderly hypertensive patients(P<0.05).The area under the ROC curve(AUC)of Lp-PLA2 predicting unstable carotid atherosclerotic plaque was 0.921,and when the best cut-off value was 551.15 U/L,its prediction sensitivity was 75%and specificity was 94%.Conclusion The activity level of plasma Lp-PLA2 is significantly elevated in middle-aged or elderly patients with hypertension complicated with unstable carotid atherosclerotic plaque,and it is considered to be an independent risk factor.The activity level of Plasma Lp-PLA2 delivers high predictive value for unstable carotid atherosclerotic plaque.When its value is 551.15 U/L,it can help predict whether the plaque is stable,and it is expected to be an inflammatory marker for early warning on early clinical evaluation of cerebrovascular embolic events. |
