OBJECTIVES: To explore the effectiveness of the mobile app-based multidisciplinary exercise management on patients who receive percutaneous coronary intervention (PCI). METHODS: From January to October 2020, 54 patients after PCI were randomly assigned to the intervention group (n = 27) and the control group (n = 27). The intervention group received the mobile app-based multidisciplinary exercise management, whereas the control group received routine care. The patients after PCI began to take intervention one month after the operation, and the intervention lasted for two months. Before and after the intervention, 6-Minute Walking Distance was used to evaluate the patient's exercise tolerance, and the patient's exercise compliance was evaluated according to the patient's exercise status recorded by the mobile app. The cognitive questionnaire on knowledge about PCI treatment for Coronary Heart Disease, the Self-efficacy for Chronic Disease Scale and the Perceived Social Support Scale were used to evaluate patients' disease-related cognition, self-efficacy and perception of social support. This study was registered on ClinicalTrials.gov with registration number ChiCTR2000028930. RESULTS: Totally 51 patients after PCI who completed this study (25 patients in the intervention group and 26 patients in the control group) were included in the analysis. After 2 months of intervention, the exercise compliance of patients in the intervention group was better than that in the control group. And 6-Minute Walking Distance (469.36 +/- 57.48 versus 432.81 +/- 67.09), and the scores of knowledge of PCI treatment for coronary heart disease (52.64 +/- 9.82 versus 42.42 +/- 8.54), Self-efficacy for Chronic Disease Scale (42.40 +/- 8.04 versus 36.88 +/- 7.73) and Perceived Social Support Scale (74.04 +/- 5.73 versus 66.69 +/- 6.86) in the intervention group were higher than those in the control group with statistical significance (p < 0.05). CONCLUSIONS: The multidisciplinary exercise management based on the mobile app can effectively improve exercise tolerance, exercise compliance, disease-related cognition, self-efficacy, and perception of social support during exercise training for patients after PCI.
