Influence Of Cognitive Level Of AMI Symptoms And Treatment On The Patients’ Emergency PCI Decision-Making

Objective: The purpose of this study was to investigate the cognitive status of AMI inpatients’ knowledge about acute myocardial infarction symptoms,treatment and related risk factors,and to explore its influence on the patients’ emergency PCI decision-making.Methods: A total of 169 patients with acute myocardial infarction in the Department of Cardiology of Xiangya Hospital of Central South University from July to December 2021 were enrolled in this study and investigated with self-designed structured questionnaire,which cantains the main symptoms and risk factors of acute myocardial infarction(AMI)’,the first response at the onset of symptoms and the awareness of AMI treatment.SPSS 25.0 software was used for data analysis to analyze the cognitive differences of the main AMI symptoms,risk factors,the first response to the onset of AMI symptoms and the cognitive differences of AMI treatment methods known between the both groups of patients who received emergency PCI and those who did not receive PCI.Finally,Logistic regression was used to analyze the factors affecting the decisionmaking of AMI patients.Results:1.There were 57 cases of 169 AMI patients undergoing emergency PCI,accounting for only 33.73%.The proportion of receiving health education in the emergency PCI group was significantly higher than that in the non-emergency PCI group,and the proportion of delayed hospitalization in the emergency PCI group was lower than that in the nonemergency PCI group.2.In the emergency PCI group,the awareness rate of main clinical symptoms of AMI,chest pain or discomfort,sudden shortness of breath or dyspnea,the risk factors of coronary heart disease,smoking,obesity,hypertension,hyperlipidemia and family history of early coronary heart disease were significantly higher than those of non-emergency PCI group.3.Only 37.3% of AMI patients knew that emergency PCI was an effective treatment for AMI.Compared with the non-emergency PCI group,in the emergency PCI group,the proportion of patients’ first reaction in calling 120 emergency vehicle,contacting relatives for advice,contacting community doctors for advice,and the awareness rate of emergency PCI being an effective treatment for AMI were significantly higher than those of non-emergency PCI group.4.Multivariate Logistic regression analysis showed that the symptoms of sudden shortness of breath or dyspnea occurred when AMI attack was known(OR=3.042;95%CI= 1.24 to 7.45),the first response was to call120 emergency vehicle(OR=1.128;95%CI= 1.030-1.544),and the first response was to contact a community doctor for advice at the onset of symptoms(OR=1.107;95%CI= 1.03-1.42),and time of delay for hospitalization(OR=0.046;95%CI=0.020～0.107)were independent influencing factors of the decision-making of AMI patients.Conclusions:1.The proportion of AMI patients receiving emergency PCI treatment is too low.2.AMI patients in non-emergency PCI group have lower cognition level of main symptoms of AMI and risk factors of coronary heart disease than that in emergency PCI group.3.The cognitive level of the first reaction at the onset of AMI,the proportion of awareness of treatment methods for AMI and knew that emergency PCI was an effective treatment for AMI in non emergency PCI AMI patients were lower than that of emergency PCI AMI patients;4.The cognitive level of the main symptoms of AMI and the correct response to AMI were the influencing factors for the patients’ emergency PCI decision-making.
