Abstract: Objective To investigate the subjective well-being status and influencing factors of elderly patients with myocardial infarction in the community and explore effective intervention measures.Methods A total of 110 elderly patients with myocardial infarction from May 2020 to February 2021 in a community in Luoyang City were selected as the research objects.The general information questionnaire and the overall well-being scale developed by the existing literature research were used to investigate the research objects.The status of their subjective well-being were examined and the influencing factors analyzed to provide nursing intervention measures.Results The overall subjective well-being scores of elderly patients with myocardial infarction in the community were lower than the Chinese norm.Male scores and female scores were lower than the Chinese norms of men and women(P<0.05).Gender,occupation,living environment,economic pressure,and complications were all influencing factors of the subjective well-being of elderly patients with myocardial infarction in the community(P<0.05).After Logistic multi-factor analysis,living with their children was a protective factor for the subjective well-being of elderly patients with myocardial infarction in the community.Poor conditions and comorbidities were risk factors for the subjective well-being of elderly patients with myocardial infarction in the community(P<0.05).Conclusion Community elderly patients with myocardial infarction have low subjective well-being.Gender,female,poor economic status,comorbidities,and farmers are all risk factors that affect their subjective well-being.Based on this,formulating the best nursing measures can improve the subjective well-being of elderly patients with myocardial infarction.
