Abstract:
Objective To investigate the correlations between lipoprotein associated phospholipase A2(Lp-PLA2),platelet aggregation rate(PAG),the ratio of mean platelet volume to platelet count(MPV/PLT)and major adverse cardiovascular events(MACE)in elderly patients with coronary heart disease(CHD).Methods The clinical data of 162 elderly patients with CHD admitted to Jianhu Hospital affiliated to Nantong University from August 2020 to September 2021 were collected retrospectively.All the patients were treated with aspirin orally and followed up for 1 year.The development of MACE within 1 year was recorded.MACE occurred in 30 patients(development group)and the other 132 patients without MACE were assigned to non-development group.Serum Lp-PLA2,PAG,and MPV/PLT were compared between the 2 groups at admission.Logistic regression was used to analyze the relationship between these parameters and MACE in elderly CHD patients.Receiver operating character(ROC)curve was used to evaluate the value of serum Lp-PLA2,PAG,MPV/PLT alone and jointly at admission in predicting MACE within 1 year.Results The proportions of patients with age≥75 years and hypertension in the development group were significantly higher than those in the non-development group(P<0.05).Serum Lp-PLA2,PAG,MPV/PLT in the development group were also significantly higher than those in the non-development group(P<0.05).Binary logistic regression analysis showed that hypertension,Lp-PLA2,PAG,and MPV/PLT were influence factors of MACE in elderly CHD patients(P<0.05).ROC curve results showed that the area under curve(AUC)values of Lp-PLA2,PAG,MPV/PLT alone or jointly were 0.832,0.817,0.841 and 0.939 in predicting MACE in elderly CHD patients.Conclusion Overexpression of Lp-PLA2,PAG and MPV/PLT are closely related to the development of MACE in elderly CHD patients.During hospitalization,the risk of MACE can be assessed by detecting Lp-PLA2,PAG,and MPV/PLT,and timely clinical intervention can be carried out.
