Background. Coronary heart disease (CHD) is the leading cause of death worldwide. The incidence of cardiovascular disease is especially common in low-level and middle-income countries. With the increase in the number of patients with CHD and the complexity of treatment on patients with CHD, many hospitals are devoted to developing new models of care and management for patients with CHD. Understanding the unique characteristics of the patient’s condition, including factors related to self-management, cognitive function, and sleep quality, will lead to a substantial reduction in cardiovascular disease and related mortality. Objective. To investigate the correlation among sleep quality, cognitive function, and self-management ability in hospitalized elderly patients with coronary heart disease (CHD). Methods. 120 hospitalized elderly patients with coronary heart disease (CHD) were investigated by using a self-designed general data questionnaire, Pittsburgh Sleep Quality Index (PSQI), Montreal Cognitive Function Assessment (MoCA) scale, and Coronary Heart Disease Self-management Behavior Scale (CSMS). Results. The Spearman analysis showed that sleep quality was positively correlated with cognitive function in hospitalized elderly CHD patients (). Sleep quality was positively correlated with self-management ability in CHD patients (). Conclusion. Improving the cognitive function and self-management ability of elderly patients with coronary heart disease can improve their sleep quality.

老年冠心病住院患者睡眠质量、认知功能与自我管理能力的相关性研究

背景。冠心病 (CHD) 是全球主要的死亡原因。心血管疾病的发病率在低收入和中等收入国家尤为普遍。随着冠心病患者数量的增加和冠心病患者治疗的复杂性，许多医院致力于为冠心病患者开发新的护理和管理模式。了解患者病情的独特特征，包括与自我管理、认知功能和睡眠质量相关的因素，将大大降低心血管疾病和相关死亡率。客观的. 探讨老年冠心病住院患者睡眠质量、认知功能与自我管理能力的相关性。方法。采用自行设计的一般数据问卷、匹兹堡睡眠质量指数（PSQI）、蒙特利尔认知功能评估（MoCA）量表和冠心病自我管理行为量表对120名住院老年冠心病（CHD）患者进行调查。 CSMS）。结果。Spearman 分析显示，住院老年冠心病患者睡眠质量与认知功能呈正相关。）。睡眠质量与冠心病患者的自我管理能力呈正相关（）。 结论。提高老年冠心病患者的认知功能和自我管理能力可以改善其睡眠质量。
