Abstract：【Objective】 To explore the influence of cognitive level of clinical symptoms, treatment methods and other related knowledge on the decision-making of emergency percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction(STEMI). 【Methods】 A total of 195 inpatients with STEMI admitted to our department from July 2021 to July 2022 were selected. According to whether emergency PCI was performed, the patients were divided into the emergency PCI group (n=68) and the non-emergency PCI group (n=127). The awareness of main clinical symptoms of acute myocardial infarction (AMI), first reaction when AMI occurred and treatment methods was compared between the two groups. 【Results】 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 pre-hospital treatment delay was significantly lower than that in the non-emergency PCI group, with statistically significant differences (P<0.05). The proportion of patients in the emergency PCI group who knew that sudden chest pain or discomfort, sudden shortness of breath or dyspnea were the onset symptoms of AMI was significantly higher than that in the non-emergency PCI group, with a statistically significant difference (P<0.05). The proportions of patients in the emergency PCI group whose first reaction to AMI was to call 120 emergency ambulance and contact the nearest community hospital for advice were significantly higher than those in the non-emergency PCI group, with statistically significant differences (P<0.05). The proportion of patients in the emergency PCI group who knew that PCI was a treatment method for AMI was significantly higher than that in the non-emergency PCI group, and the proportion of those who did not know the treatment method for AMI was significantly lower than that in the non-emergency PCI group, with a statistically significant difference (P<0.05). Multivariate Logistic regression analysis showed that knowing the symptom of sudden shortness of breath or dyspnea when AMI occurs, knowing PCI, as well as the first reaction of calling 120 emergency ambulance and contacting doctors of the nearest hospital for advice when symptoms occur were independent protective factors for AMI patients to make emergency PCI decisions (P<0.05).【Conclusion】 The proportion of STEMI patients receiving emergency PCI is too low. The cognitive level of main clinical symptoms of AMI, first reaction when AMI occurs and treatment methods significantly affects the emergency PCI decision-making of STEMI patients.
