社会支持水平、健康相关生活质量与老年不稳定型心绞痛患者出院后焦虑的关系研究OA

Objective To investigate the relationship between social support level,health-related quality of life and post-discharge anxiety in elderly patients with unstable angina.Methods This study was a single-center retrospective cohort study,a total of 491 elderly patients with unstable angina admitted to Tianjin Third Central Hospital from September 2021 to September 2022 were selected as the research subjects.The clinical data of the patients were collected,the patients were divided into the anxiety group(166 cases)and the non-anxiety group(325 cases)according to anxiety status during the 1-year after discharge.Univariate and multivariate Logistic regression analysis was used to explore the influencing factors of post-discharge anxiety in elderly patients with unstable angina.The ROC curve and decision curve were used to explore the predictive value and clinical applicability of the Social Support Rating Scale(SSRS)score,MacNew Heart Disease Health-related Quality of Life(MacNew HRQL)score for post-discharge anxiety in elderly patients with unstable angina.Results The proportion of men,the proportion of patients living alone,the proportion of patients with diabetes history,systolic blood pressure,the proportion of patients with left main disease,hemoglobin,the incidence of major adverse cardiovascular events(MACE)in the anxiety group were higher than those in the non-anxiety group,the age was less than that in the non-anxiety group,and the SSRS score,and MacNew HRQL score were lower than those in the non-anxiety group(P<0.05).Univariate Logistic regression analysis results showed that gender,age,diabetes history,systolic blood pressure,left main disease,hemoglobin,SSRS score,MacNew HRQL score,and MACE may be the influencing factors of post-discharge anxiety in elderly patients with unstable angina(P<0.05);multivariate Logistic regression analysis results showed that SSRS score,and MacNew HRQL score were independent influencing factors of post-discharge anxiety in elderly patients with unstable angina(P<0.05).The ROC curve analysis results showed that the AUC of SSRS score,and MacNew HRQL score for predicting post-discharge anxiety in elderly patients with unstable angina was 0.928[95%CI(0.904-0.951)],0.651[95%CI(0.604-0.699)],respectively.The decision curve analysis results showed that when the threshold probability was from 0.1 to 1.0,the net benefit rate of SSRS score in predicting post-discharge anxiety in elderly patients with unstable angina was greater than 0;when the threshold probability was from 0.1 to 0.5,the net benefit rate of MacNew HRQL score in predicting post-discharge anxiety in elderly patients with unstable angina was greater than 0.Conclusion Social support level and health-related quality of life are independent influencing factors of post-discharge anxiety in elderly patients with unstable angina,and social support level has high predictive value and clinical applicability for post-discharge anxiety in elderly patients with unstable angina.
