Abstract
Rheumatic heart disease (RHD) is a chronic condition that frequently necessitates valve replacement surgery. However, the postoperative recovery period can be prolonged, and persistent cardiac dysfunction may occur. This underscores the need for effective nursing interventions to improve patient outcomes. This study aimed to evaluate the effectiveness of the "one disease, one product" nursing model combined with self-efficacy enhancement on cardiac function and quality of life in patients undergoing RHD valve replacement. A retrospective analysis was conducted on 100 patients who underwent RHD valve replacement between January and June 2022. Based on nursing history, patients were assigned to an experimental group (n = 50) or a control group (n = 50). The experimental group received "one disease, one product" nursing combined with self-efficacy interventions, while the control group received standard postoperative care. Cardiac function, complication rates, quality of life, and nursing satisfaction were assessed and compared between groups before and after the intervention. Patients in the experimental group showed significantly greater improvements in left ventricular ejection fraction, cardiac output, and left ventricular end-diastolic diameter compared to the control group (P < .001). The incidence of complications was also lower in the experimental group. Quality of life measures-including medical management, physical strength, social functioning, daily activities, and work performance-were significantly higher in the experimental group (P < .05). Overall nursing satisfaction in the experimental group reached 90.00%, significantly exceeding that of the control group (P = .026). The combination of the "one disease, one product" care model with self-efficacy enhancement significantly improves cardiac function, quality of life, and nursing satisfaction in patients undergoing valve replacement for RHD. This integrated nursing approach holds considerable promise for improving postoperative recovery and patient-centered outcomes in similar clinical settings.
