Study On The Relationship Between LP-PLa2、NLR And Coronary Heart Disease In The Elderly

Objective: to study the changes of Lp-PLA2 and NLR in flowing blood of mature sick with ischemic heart disease,and to probe the similarity between Lp-PLA2,NLR and coronary atherosclerosis in mature sick with ischemic heart disease.Methods: from January 2020 to April 2022,120 mature sick with ischemic heart disease who were suffering in the older center,cardiology and general section of the people’s Clinic of Interior Country Independent area were picked and included in the survey sample,including 80 sufferers with acute stroke illness(ACS),comprising 41 instance with acute infarction closure(AMI)and 39 sick with shaky heart assault(UA).40 sicks with chronic coronary syndrome(CCS),all with stable heart attack(SAP),and 106 mature sick with non-ischemic heart disease accepted to clinic in that period were inserted in the curb group.The objective baseline data such as mating,period,curing history,boozing history,over history,height and weight were collected routinely,and the data of Lp-PLA2,NLR and coronary artery imaging were obtained by hematology,ECG and heart attack angiography.The differences of Lp-PLA2 and NLR levels among various subgroups of ischemic heart disease were observed,and the link between Lp-PLA2 and NLR and the degree and rank of coronary abrasion in older subject with stroke heart coronal was assayed.outcomes:(1)similarity between groups: there were important differences in medical indexes such as Neu,LY,SBP,GLU,TC,LDL-C,HDL-C,TBIL,cTnT,h-FABP,Lp-PLA2,NLR,stenosis amount and gensini score between the pragmatic team and the administer team(p <0.05),but there were no other clinical indexes.(2)The mature sick with coronary heart disease were divided into three sub-classes: AMI class>UA class and>SAP class.There were numerical variations among the trio sub-classes(P < 0.05)in the indexes such as cTnT,mitral branches,gensini score,NLR and Lp-PLA2,among which the levels of cTnT,mitral branches,gensini score,NLR and Lp-PLA2 were among the three subgroups.(3)The results of liaison review between the check class and the manage class showed that(1)the denseness of Lp-PLA2 in minor line was absolutely affiliated with gensini score,GLU,cTnT,LDL-C and the lot of stenosis(P < 0.05),and the correlation coefficients were 0.280,0.145,0.188 and 0.141 respectively.There was no correlation with TC,TBIL,h-FABP and NLR(P >0.05).(2)There was a sure relation between peripheral blood NLR and gensini score,cTnT and the lot of stenoses(P < 0.05),and the link coefficients were 0.151,0.195 and 0.131 respectively.There was no obvious correlation with GLU,LDL-C,TBIL,h-FABP and Lp-PLA2(P > 0.05).(3)To able was no telling each Lp-PLA2 other NLR(r = 0.082,P =0.219 > 0.05).(4)lancer relation study shown that:(1)Lp-PLA2 was completely related with the number of miosis and gensini score(P < 0.05),with similarity teams of 0.191 and 0.153;There was no major coefficient with cTnT and NLR(P>0.05).(2)There was certain coefficient between NLR and stenosis number and gensini score(P < 0.05),with association coefficients of 0.208 and 0.198;There was no momentous coefficient between cTnT and Lp-PLA2(P>0.05).(5)Logistic regression review showed that peripheral blood Lp-PLA2 and NLR were the related factors of stroke heart disease in the elderly.It was discover that the risk of CHD in senior clients would growth by 1.983 times with the increase of peripheral blood Lp-PLA2 concentration by 1 U.Every 1U increase in NLR will increase the risk of CHD in older patients by 1.054 times.(6)ROC curve study revealed that LP-PLA2 and NLR in peripheral blood could predict coronary heart disease in the elderly,and the curve area of LP-PLA2 level(AUC=0.952,P=0.000)was larger than that of NLR(AUC=0.620,P=0.002).The joint curve area of the two indicators is(AUC=0.960,P=0.000),which indicates that the joint prediction value of the two indicators is higher.Conclusion:(1)Lp-PLA2 and NLR in peripheral blood are related to senile stroke heart illness,and Lp-PLA2 and NLR are involved in the happening and enlargement of coronary atherosclerosis in senile CHD patients.(2)The balance of abdominal atherosclerotic slab in older patients with stroke soul illness may be related to Lp-PLA2 and NLR.Lp-PLA2 and NLR can predict the used of the degree of something undesirable of coronary heart sickness and tablet the condition of being steady and not changing in the elderly.(3)The combination of inflammatory markers(LP-PLa2,NLR)can improve the prediction efficiency of senile CHD.
