Abstract: Objective To explore the effect of green channel emergency nursing based on mind mapping on percutaneous coronary intervention（PCI） of patients with acute myocardial infarction（AMI）．Methods A study was conducted on 80 AMI patients admitted to Tianjin People's Hospital from January 2022 to December 2024．The patients were divided into two groups based on their admission time．The 40 patients who received routine emergency nursing interventions from January 2021 to June 2023 were assigned to the conventional group,while the 40 patients who received green channel emergency nursing based on mind mapping from July 2023 to November 2024 were assigned to the mind mapping group．The emergency treatment efficacy,vital signs（heart rate,diastolic blood pressure,systolic blood pressure）,myocardial injury indicators（phosphocreatine kinase[CK-MB],and troponin I[cTn1]）between two groups of patients before and after emergency treatment were compared．Results The pre-examination time,consultation time,catheterization room activation time and emergency room to PCI operation time of mind mapping group were all shorter than those of conventional group（P<0.05）．Compared with the vital signs before and after emergency treatment,we found that the heart rate,diastolic pressure and systolic blood pressure of the two groups decreased after emergency treatment（P<0.05）,and there was no significant difference between the heart rate,diastolic pressure and systolic blood pressure of the two groups before and after emergency treatment（P>0.05）．Comparing the myocardial injury indicators before and after emergency treatment,there was no significant difference in CK-MB and cTn1 between the two groups before emergency treatment（P>0.05）．After emergency treatment,CK-MB and cTn1 in the mind map group were lower than those in the conventional group and before emergency treatment（P<0.05）．Comparing the intervention satisfaction,it was found that the mind mapping group of 100.00% was higher than the conventional group of 85.00%（P<0.05）．Conclusions Green channel emergency nursing based on mind mapping can improve the efficiency of emergency treatment for AMI patients,stabilize their vital signs,reduce myocardial injury,improve patient intervention satisfaction．
