Application of intervention of information motivation behavior skill (IMB) model in the cardiac rehabilitation of patients with coronary heart disease

Objectives: To explore the effects of information motivation behavior skill (IMB) model in the cardiac rehabilitation of patients with coronary heart disease.

Methods: We analyzed data from medical records of patients with coronary heart disease who had received cardiac rehabilitation treatment in the Department of Cardiology of our hospital from April 2019 to May 2021. Data from 52 patients who had received routine nursing rehabilitation (Mode-I) and 56 patients that received IMB model-oriented nursing rehabilitation (Mode-II) was included. We calculated indexes of cardiopulmonary function, physical fitness, and nursing satisfaction, and self-efficacy scores (GSEs) before and three months after the intervention for patients in the two rehabilitation groups.

Results: We found similar LVEFs, SVs, anaerobic thresholds, peak oxygen uptake scores, PEFs, and FVCs in patients undergoing either of the two rehabilitation modes before the interventions (P>0.05). However, these indexes were significantly higher in patients undergoing Mode-II rehabilitation after the intervention, compared to Mode-I group (P<0.05). We found similar aerobic endurances, upper limb and lower limb muscle strengths in patients undergoing either method before the intervention (P>0.05). After the treatment, these parameters were higher in the Mode-II group compared to Mode-I group (P<0.05). The scores of daily life behavior management, cognitive symptom management, and disease management between the two groups were similar before the intervention (P>0.05). After the intervention, patients undergoing Mode-II rehabilitation had significantly higher values than patients in the Mode-I group (P<0.05). The nursing satisfaction of the patients in the Mode-II group (94.64%) was significantly higher than that of patients in the Mode-I group (80.77%) (P<0.05).

Conclusion: IMB model intervention measures can improve cardiopulmonary function and physical fitness, and enhance the patients’ self-efficacy, resulting in high nursing satisfaction.
