Seasonal activity in people with heart failure who have pacemakers or ICDs

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study follows adults with heart failure who have cardiac implantable electronic devices over a full year to measure device-recorded physical activity. Activity data from the implanted devices will be linked to local weather station records to compare activity levels across seasons. Eligible participants are ambulatory adults in NYHA class I–III with ischemic or non-ischemic cardiomyopathy who live within about 50 miles of a weather reporting station; those with LVADs, major mobility-limiting conditions, recent major surgery, or cognitive impairment are excluded. Investigators will analyze seasonal patterns and the magnitude of changes in daily activity and explore associations with temperature and other weather variables.
