Overview
Based on the monitoring data of wearable devices, with cardiac output (CO) as the gold standard, this study intends to develop a non-invasive evaluation model of CO based on wearable data, and optimize the parameters to realize the cardiac capacity detection function in resting and exercise states on the wearable device.
Interventions
- Other Exercise
Cardiac output (CO) was measured after exercise intervention in patients with normal cardiac function
Primary outcome measures
- cardiac output [Time frame: From enrollment to the end of follow-up at 1 month]
Secondary outcome measures (1)
- Heart failure [Time frame: From enrollment to the end of follow-up at 1 month]
Eligibility criteria
Inclusion criteria

- Left ventricular ejection fraction (Left ventricular ejection fraction, LVEF) ≥50% (100 subjects)
- Able to use smart phones and operate wearable devices such as wristbands/watches
Exclusion criteria
- Patients with pacemaker implantation
- No smartphone
- Currently participating in other clinical trials
- Lactating women
- Pregnant Women
- Unable to run and ride due to personal physical and external reasons (subjects participating in the exercise state cardiac output model study)
- Physical examination results in the past year have clear cardiovascular, metabolic, bone and joint related diseases that have exercise risk, or have diseases and related potential health risks confirmed by the self-examination form of physical status before exercise (participants in the exercise state cardiac output model study)
- No informed consent was obtained
