Analysis Of Autonomic Perception And Its Influencing Factors In Elderly Patients With Acute Myocardial Infarction After PCI

Objective: The purpose of this study was to understand the status quo of autonomous perception in elderly patients with acute myocardial infarction after PCI.To explore the factors affecting the level of autonomous perception in elderly AMI patients after PCI and put forward reasonable suggestions;To explore the correlation and influencing factors between health-related quality of life and autonomous perception in elderly patients with AMI.Methods: This study is a descriptive study.The research samples were collected from field questionnaires and face-to-face interviews.400 elderly patients with AMI after PCI who were admitted to the cardiovascular department and geriatrics department of a third-class one hospital was chosen to carry out the questionnaire survey.,from February2022 to Oct 2022,.Based on the questionnaire,the Autonomic Perception Level Scale(PEAS-CV)was used to collect the general demographic data and clinical data of older people and Health Related Quality of Life Scale(SF-36)were used to measure the patients.There are total of 405 samples were collected,400 valid questionnaires were collected,and the effective rate was 98.76%.The software SPSS23.0 was used to process the experimental results statistically.Frequency and component are used to describe the general information of the research object.Mean,standard deviation and component ratio were used to describe the distribution of autonomic perception population and its three dimensions,health-related quality of life and its eight dimensions.The influence factors were determined by independent t test and one-way variance analysis.Pearson correlation analysis statistically analyzed the correlation between autonomic perception and health-related quality of life.Multivariate linear regression was carried out with meaningful variables in univariate analysis and correlation analysis as independent variables.Results: 1.Status quo of autonomic perception in elderly patients with acute AMI after PCI: The average score of the three dimensions of the study object was(3.00±0.43)freedom,(2.47±0.54)individuality,(2.14±0.37)independence,the total score of autonomic perception was(103.68±13.17),and the average score of the items was(2.52±0.32).2.Independent sample T-test and one-way analysis of variance influence the overall and freedom dimensions of autonomous perception in elderly AMI patients: Age,marital status,educational level,current living status,payment method of medical expenses,main economic source,family history of coronary heart disease,PCI frequency,Killip cardiac function grade,number of stent implantation,and type of postoperative medication;Independence dimension: age,marital status,education level,living only with spouse,payment method of medical expenses,economic source,PCI frequency,number of stent implantation,family history of coronary heart disease,and type of postoperative medication.Individual dimension: marital status,home address,per capita monthly income,living status,payment method,economic source,postoperative medication type.3.Pearson Correlational Analysis showed that the QOL was positively correlated with QOL(r = 0.263,p <0.05).4.Multiple linear regression analysis shows that the factors affecting the overall level of autonomous perception are: Physical function(β=0.334,p < 0.001),retirement(β=-0.137,p < 0.001),health-related quality of life(β=0.273,p < 0.001),per capita monthly income(β=0.080,p < 0.001),mental health(β=0.085,p < 0.001),retirement salary(β=0.052,p < 0.001).Conclusions: 1.According to Linkert Level 4 scoring criteria,elderly AMI patients were at the average level in autonomic perception overall,and at the high,medium and medium level in three dimensions respectively.2.There is a correlation between autonomous perception and health-related quality of life.3.The overall important factors affecting the autonomous perception of elderly AMI patients were: physiological function,retirement,health-related quality of life,per capita monthly family income,mental health,and retirement salary;The main influencing factors on the dimension of freedom were: physiological function,retirement,mental health,health-related quality of life,age,residence with spouse,per capita monthly household income,public expenses,and retirement wage;The important factors affecting the individual dimension are: per capita monthly income,separation,pension insurance,living with children,health-related quality of life;The important factors influencing the independence dimension are: physiological function,energy,education level,retirement,pension insurance,city life,living with children,new rural cooperative medical care,family history of coronary heart disease.
