Abstract：【Objective】 To analyze the related factors that affect the poor prognosis of intraventricular catheterization in patients with acute myocardial infarction (AMI). 【Methods】 A prospective study was conducted on 107 AMI patients admitted to our hospital from May 2019 to February 2022 who were mistakenly activated by intracardiac catheterization. Based on the patient's prognosis,they were divided into an observation group (those with poor prognosis,n=31) and a control group (those with good prognosis,n=76). Clinical data of patients were collected and logistic multiple factor regression analysis was used to analyze the related factors that affect the poor prognosis of cardiac catheterization in AMI patients.【Results】 The incidence of poor prognosis in 107 AMI patients with intracardiac catheter misactivation was 28.97% (31/107). There was a statistically significant difference (P<0.05) between the two groups of patients in terms of cardiovascular risk factors,history of coronary heart disease,previous PCI history,time of first medical contact with the device,left bundle branch block,time of infarcted artery reconstruction,and chest pain symptoms. Logistic regression analysis showed that the time of infarcted artery reconstruction,history of coronary heart disease,previous PCI history,time of first medical contact with the device,left bundle branch block,and chest pain symptoms were the influencing factors for poor prognosis in patients with intracardiac catheter room activation (P<0.05). 【Conclusion】 The poor prognosis of AMI patients with intracardiac catheterization room misactivation is influenced by factors such as infarct artery reconstruction time,history of coronary heart disease,previous PCI history,time of first medical contact with the device,left bundle branch block,chest pain symptoms,etc. Clinical scholars can develop intervention measures based on these factors to reduce the occurrence of adverse cardiovascular events and improve patient prognosis.
