Effects of Ward Noise Management Combined with Guided Imagery Relaxation on Recovery and Anxiety-Depression after Percutaneous Coronary Intervention in Patients with Coronary Heart Disease and Diabetes Mellitus

OBJECTIVE: Patients with diabetes mellitus and coronary heart disease may experience delayed recovery and psychological distress after percutaneous coronary intervention. This study assessed the effects of ward noise management combined with guided imaginative relaxation on postoperative recovery and psychological status. METHODS: We included 114 patients with coronary heart disease complicated by diabetes mellitus who underwent percutaneous coronary intervention between February 2023 and January 2025. According to the admission period, patients were assigned to the control group ( n = 57), receiving routine cardiology nursing care, or the observation group ( n = 57), receiving ward noise management combined with guided imagery relaxation in addition to routine care. We assessed anxiety and depression using the Hospital Anxiety and Depression Scale (HADS), sleep quality using the Pittsburgh Sleep Quality Index (PSQI), activities of daily living using the Barthel Index (BI), and pain intensity using the Visual Analog Scale (VAS). We also recorded postoperative length of hospital stay. RESULTS: Baseline characteristics and prenursing measure scores showed no significant differences between the two groups ( P > 0.05). Before discharge, the observation group had significantly lower HADS-A, HADS-D, PSQI, and VAS scores, and a significantly higher BI score than the control group (all P < 0.001). Postoperative hospital stay was also shorter in the observation group. CONCLUSION: Ward noise management combined with guided imagery relaxation may improve psychological status, sleep quality, pain, and functional recovery in patients with diabetes mellitus and coronary heart disease after percutaneous coronary intervention.
