ABSTRACT
OBJECTIVE: This study aimed to investigate the effects of binaural beat technology (BBT) sound stimulation therapy on the physiological and psychological functioning of elderly patients with coronary heart disease (CHD) following percutaneous coronary intervention (PCI).
METHODS: This study is a retrospective cohort study. Clinical data of 104 patients with CHD undergoing PCI from January 2022 to December 2024 were retrospectively analysed. The patients were grouped according to the time of introduction of the hospital's postoperative therapy plan into the conventional group (n = 53, patients receiving standard therapy between January 2022 and May 2023) and the BBT group (n = 51, patients receiving standard therapy plus BBT therapy between June 2023 and December 2024). Comparisons included physiological indices (diastolic blood pressure [DBP], systolic blood pressure [SBP], heart rate [HR]); sleep quality (Richards-Campbell Sleep Questionnaire [RCSQ] score, polysomnography [PSG] parameters [slow-wave sleep duration, total sleep time, nocturnal awakenings]); perceived stress (10-item Perceived Stress Scale [PSS-10]); mood states (Brief Profile of Mood States [BPOMS]) and psychological distress (Hospital Anxiety and Depression Scale [HADS] anxiety subscore, depression subscore and total score).
RESULTS: One week after the operation, the BBT group had lower levels of DBP, SBP, HR, PSS-10 score, BPOMS score, HADS anxiety, depression dimension scores and total HADS score; higher RCSQ score; longer deep sleep time and total sleep time and fewer night awakenings than the conventional group (P < 0.05).
CONCLUSION: BBT sound stimulation therapy improves haemodynamic stability, enhances sleep architecture, reduces perceived stress, ameliorates mood disturbances and alleviates psychological distress in elderly patients with CHD post-PCI.
