Intervention group
In addition to the exercise protocol, the intervention group used a wearable smart device and the 5G IOT CR intelligence platform for remote management of CR. CR was performed three times a week for 50–60 min each session. The total number of interventions was 36 sessions.Researchers verified whether the patients’ mobile phones were 5G-enabled. If not, the research group equipped the patients with 5G-enabled mobile phones and installed the Healthy Life Cycle application (app) before the patients were discharged. Patients also received wearable smart remote monitoring devices that were connected to the Healthy Life Cycle app via Bluetooth (pulse oximeter, model: A0J-70C, Shenzhen City, China; dynamic electrocardiogram (ECG) monitor, model: ECG-P01, Hangzhou City, China; arm-type electronic blood pressure monitor, model: B65T, Shenzhen City, China) (Figs. Portable cardiac rehabilitation equipment.The operation of the 5G Internet of Things cardiac rehabilitation platform.Patients were assisted by researchers and asked to log in to the Healthy Life Cycle app, click on “Rehabilitation Center” to access the online program, and wear the wearable device to monitor their vital signs and upload the data to the app (Fig. 5G + IOT smart CR service architecture.The rehabilitation exercise class was the same as that for the control group. Vital signs were recorded after each exercise, and the researchers ensured there were no abnormalities before the patients moved on to the next part of the exercise program. Patients could learn about their training and vital signs through the app, and the rehabilitator could adjust the exercise training pattern, intensity, and time for the patient on the basis of changes in the vital signs during exercise, to achieve personalized rehabilitation.A psychologist was assigned to this study to provide psychological counseling to patients once a month to ensure their psychological well-being.
