An observational study in Cardiac Output, sponsored by Navy General Hospital, Beijing. Not yet recruiting. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-04-22.
Sponsored by Navy General Hospital, Beijing · Observational
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.
Navy General Hospital, Beijing is the lead sponsor of 36 studies on the registry; 22 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Two hundred HF patients with an left ventricular ejection fraction (LVEF) of less than 50% and 100 normal cardiac function subjects with an LVEF of 50% or greater were enrolled
Exclusion Criteria:
Cardiac output (CO) was measured after exercise intervention in patients with normal cardiac function
cardiac output
Taking cardiac function indicators such as cardiac output by echocardiography as the gold standard, using wearable device monitoring data（Photoplethysmographic pulse wave）, the resting state cardiac output artificial intelligence machine learning model was established, and the sensitivity, specificity, positive predictive value, negative predictive value, F1 score, diagnostic efficiency Area Under Curve (AUC), and the sensitivity, specificity, positive predictive value, negative predictive value, F1 score, diagnostic efficiency of the model were calculated. AUC), precision and precision-recall curves were used to evaluate the performance of the model.
Time frame: From enrollment to the end of follow-up at 1 month
Heart failure
Heart failure symptoms, acute heart failure episodes, rehospitalization rates, and cardiovascular mortality
Time frame: From enrollment to the end of follow-up at 1 month
