Study on Cardiac Output Evaluation Based on Wearable Monitoring Data

ClinConnect Summary

This clinical trial is studying how wearable devices, like smartwatches or fitness bands, can help measure cardiac output, which is a key indicator of heart function. The goal is to create a new way to assess how well the heart is working without needing invasive procedures. Researchers want to see if they can improve how these devices detect heart capacity during times of rest and exercise.

To participate in this study, you need to be over 18 years old and have a specific heart condition where your heart's ability to pump blood is affected (either with a lower or normal ejection fraction). You should also be comfortable using a smartphone and wearable technology. However, if you have a pacemaker, are pregnant or breastfeeding, or have certain health issues that prevent you from exercising, you may not be eligible. Participants can expect to help advance heart health monitoring while using wearable devices, but the trial is not yet recruiting, so no one can join at this moment.
