ABSTRACT

【Abstract】 Objective To investigate the interventional effect of enhanced external counterpulsation on sleep quality and anxiety/depression mood in patients with coronary heart disease, and to provide a basis for clinical treatment.
Methods A total of 200 CHD patients admitted to our hospital from January 2023 to May 2025 were selected and randomly divided into an observation group and a control group using a random number table method, with 100 patients in each group. The control group received conventional drug therapy and basic nursing care, while the observation group received EECP treatment in addition to the control group's regimen. The Pittsburgh Sleep Quality Index (PSQI), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Seattle Angina Questionnaire (SAQ), and 36-Item Short Form Health Survey Questionnaire (SF-36) scores were compared between the two groups before and after the intervention.
Results After the intervention, PSQI scores decreased in both groups, with the observation group scoring lower than the control group (P < 0.05). Post-intervention, both GAD-7 and PHQ-9 scores decreased in both groups, with the observation group scoring lower than the control group (P < 0.05). After the intervention, SAQ and SF-36 scores increased in both groups, with the observation group scoring higher than the control group (P < 0.05). 
Conclusion   Enhanced external counterpulsation combined with conventional therapy can significantly improve sleep quality, alleviate anxiety and depression, reduce angina attacks, and enhance the quality of life in patients with coronary heart disease. It is worthy of clinical promotion and application.
