Dyadic coping experiences of young and middle-aged patients undergoing PCI for coronary heart disease and their spouses during the perioperative period: a qualitative study.

Objective: This study focuses on the dyadic coping units formed by middle-aged and young patients and their spouses during the perioperative period of percutaneous coronary intervention(PCI) given the trend toward a younger onset of coronary heart disease. It explores their experiences of dyadic coping during this critical transitional phase. Methods: Based on the theory of dyadic illness management, this descriptive qualitative study involved semistructured joint interviews with 19 pairs of middle-aged and young PCI patients and their spouses. Content analysis was used to identify themes, and the study adhered to the COREQ reporting guidelines. Results: The study identified five key themes: differing coping styles during the decision-making phase regarding stents, the exacerbation of psychological stress due to dual financial pressures, conflicting patterns of spousal interaction, variations in patients' perceptions of spousal support, and a lack of clear understanding regarding long-term disease management. Conclusion: Middle-aged and young patients with coronary heart disease and their spouses face multiple challenges during the perioperative period of PCI. It is recommended that a dyadic, collaborative care intervention program be developed at the family level that integrates health literacy enhancement, financial support, spousal communication and information-based continuity of care to improve disease management outcomes.
