Objective To explore the influencing factors of anxiety status in elderly emergency patients with acute myocardial infarction(AMI)undergoing multiple percutaneous coronary intervention(PCI).Methods A total of 108 elderly emergency patients with AMI who underwent multiple PCI in Beijing Rehabilitation Hospital,Capital Medical University from May 2021 to April 2023 were included as the study subjects,their anxiety status was evaluated using the Self Rating Anxiety Scale(SAS).The anxiety status of acute myocardial infarction patients with different characteristics was compared,and the influencing factors for anxiety status in the patients were analyzed.Results The SAS score of the AMI patients with multiple PCI was(65.97±5.12),indicating a moderate level of anxiety.There were statistically significant differences in SAS scores among AMI patients with different education level,types of medical insurance,activities of daily living(ADL)scores,history of smoking and drinking(P<0.05).Whereas,the difference was not statistically significant in anxiety status among AMI patients with different implanted stents,diseased vessels,age and gender(P>0.05).There was no statistically significant difference in SAS scores among AMI patients with different hypertension,hyperlipidemia,diabetes,peripheral arterial disease and medication(P>0.05).The results from multiple linear regression analysis showed that smoking history,medical insurance type,ADL score,education level,and alcohol consumption history were the influencing factors for anxiety status in AMI patients with multiple PCI treatments(P<0.05).Conclusion Elderly emergency patients with AMI underwent multiple PCI are in a moderate anxiety state,and the influencing factors are educational level,medical insurance type,ADL score,smoking history,and alcohol consumption history.
