To explore the effect of smart app and wearable-based lifestyle intervention management on vascular health, comparing different exercise with the improvement of vascular arterial stiffness. The accuracy and consistency evaluation of smart wearable devices in screening for vascular health risks were also discussed.
This study intends to carry out a randomized controlled trial to dynamically monitor a variety of cardiovascular parameters in people with high risk of vascular health, using wearable devices and artificial intelligence-assisted health management platform, and provide intelligent lifestyle intervention programs with different exercise.By observing the improvement of vascular health in the study population, the management effect of intelligent lifestyle intervention on high-risk groups of vascular health was evaluated. It is expected that through comprehensive lifestyle intervention based on smart wearable devices, early prevention and control of arteriosclerosis can be achieved, the level of hospital health management will be improved, and more physical health and health economic benefits will be obtained.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control | No Intervention | Study participants were given training on dietary patterns, regular monitoring and follow-up through apps and wearable devices, and no forced exercise measures were performed. | |
| Combined Exercise Group | Active Comparator | Study participants were given training on dietary patterns, regular monitoring and follow-up through apps and wearable devices.Based on the status of the study participants and the results of the cardiopulmonary exercise test, the investigators prescribe moderate-intensity aerobic exercise combined with resistance exercise |
|
| Mind-body Exercise Group | Experimental | Study participants were given training on dietary patterns, regular monitoring and follow-up through apps and wearable devices.A standardized Baduanjin exercise program consists of eight postures, each training time is about 30 minutes (including 10 min warm-up, 2 times of Baduanjin, and 10 min of relaxation), 5 days/week, a total of 12 weeks. |

| Regular exercise | Behavioral | Based on the study participant's status and exercise assessment, the investigators prescribe moderate-intensity aerobic exercise combined with resistance exercise. Before each exercise, preparatory activities (10min), 20-30min moderate-intensity aerobic exercise, finishing activities (10min) at the end, 5 days/week, for 12 weeks, and at the same time, choose non-consecutive 3 days of resistance training in 5 aerobic training sessions to increase resistance training (choose 1~2 muscle groups each time, 4~5 movements, repeat each action 8~12 times, repeat 2~3 sets) |
| Measure | Description | Time Frame |
|---|---|---|
| Cervical femoral pulse wave velocity（cfPWV） | The cardio-cerebrovascular and aortic function detector (Campura, France, model: Complior Analyse) was used to measure cfPWV, and the study participants were in a supine position, lying flat on the pillow, with their palms up on their sides of the body, so that their whole body was relaxed and rested for about 3 minutes. PWV can reflect arterial stiffness, and the European Society of Cardiology recommends cfPWV >10 m/s as the definitive threshold for assessing arterial functional changes in hypertension.We monitored cfPWV at baseline,3,6,9 months of the study. | baseline,3months,6months,9 months |
| Measure | Description | Time Frame |
|---|---|---|
| Brachi-ankle pulse wave velocity（baPWV） | The blood pressure of the limbs is measured with the Omron arteriosclerosis detector, and the pulse conduction velocity (baPWV) and ankle-brachial index (ABI) are calculated to automatically evaluate the degree of arteriosclerosis and blood vessel blockage. Positive criteria for baPWV: ≥1400 cm/s or baPWV% ≥ 19% is arteriosclerosis. Lower extremity vascular occlusion (ABI positive criteria): ≤0.9 for peripheral arterial stenosis and ≤0.5 for possible peripheral arterial occlusion.We monitored baPWV at baseline,3,6,9 months of the study. |

| Baduanjin | Behavioral | A professional therapist instructed the participants to learn and train Baduanjin before the intervention, and a standardized Baduanjin exercise program included eight postures, each training time was about 50 minutes (including 10 min of warm-up, 2 times of Baduanjin, and 10 min of relaxation), 5 days/week, a total of 12 weeks |

| baseline,3months,6months,9 months |
| blood pressure | Blood pressure indicator: systolic blood pressure and diastolic blood pressure.We monitored blood pressure at baseline,3,6,9 months of the study. | baseline,3months,6months,9 months |
| body weight | Using bioelectrical impedance analysis to monitor body weight,weight and height will be combined to report BMI in kg/m^2.We monitored body composition at baseline,3,6,9 months of the study. | baseline,3months,6months,9 months |
| Lipid metabolism parameters: TC(mmol/L), TG(mmol/L), HDL-C(mmol/L), LDL-C(mmol/L) | Lipid metabolism indicators: total cholesterol , triglyceride , high density lipoprotein cholesterol, low density lipoprotein cholesterol.We monitored lipid metabolism parameters at baseline,3,6,9 months of the study. | baseline,3months,6months,9 months |
| Physical fitness | The measurement of muscle strength, balance and flexibility is completed by the rehabilitation therapist, mainly including: (1) upper limb muscle strength test (dumbbell arm curl test); (2) Lower limb muscle strength test (chair standing and sitting test); (3) balance ability test; (4) Lower limb flexibility assessment (chair sitting body forward bending test); (5) Upper limb flexibility assessment (two-hand dorsum extension test). Participants were observed for changes at baseline, 3,6,9 months. | baseline,3months,6months,9 months |
| Vascular Health Index | The PWV was analyzed by the smart watch through ECG (electrocardiogram) and PPG (photoplethysmography) sensors to evaluate the degree of vascular elasticity, and the vascular health index and evaluation were obtained, and the results were divided into low-risk, medium-risk, and high-risk. | baseline,3months,6months,9 months |
| Application adherence | Study participants who received remote lifestyle interventions through the app, completed all exercise training content per week, or clocked in ≥ exercise 3 times were considered to have good compliance; Those who check in < exercise 3 times a week are considered to have poor compliance. | baseline,3months,6months,9 months |
