Summary

This study is looking at whether data from a Fitbit smartwatch (like heart rate, sleep, and steps) can help assess heart health and predict the risk of heart disease. Researchers will track 100 adults over time, comparing their wearable data with standard heart health measures. The goal is to see if everyday wearable devices can be a useful tool for heart disease prevention.
