What this trial studies

This observational cohort will provide participants with a Fitbit Charge 6 to wear continuously for six months, with device data collected via Fitabase. Clinical cardiovascular assessments and calculation of the American Heart Association Life's Essential 8 score will be performed at baseline, three months, and six months. Participants will complete weekly and monthly patient-reported outcome surveys on symptoms, sleep, mood, alcohol use, and activity. Analyses will examine whether wearable-derived biometrics, alone or combined with point-of-care measures, correlate with and predict changes in cardiovascular health and risk factors.

Who should consider this trial

Good fit: Adults aged 18 and older who can attend three clinic visits at Beacon Hospital in Dublin, have internet access, and own a smartphone compatible with the Fitbit app are ideal candidates.

Not a fit: People who are pregnant, have unstable medical conditions or cognitive impairments that prevent following the protocol, or who cannot wear a wrist device (for medical or skin reasons) may not benefit or be eligible.

Why it matters

Potential benefit: If successful, wearables could offer low-burden, continuous monitoring to detect worsening cardiovascular health earlier and support more personalized prevention.

How similar studies have performed: Prior studies have shown promising links between wearable metrics (activity, heart rate, sleep) and individual cardiovascular outcomes, but applying wearables to predict composite Life's Essential 8 scores is relatively new.
