Physical Activity, Cardiac and Skeletal Muscle Energetics in Healthy Subjects and HFpEF Patients
United States60 participantsStarted 2021-08-04
Plain-language summary
This research is being done to better understand the relationship between information collected by wearable devices and clinical measurements in people with heart failure with preserved ejection fraction (HFpEF) and others without HFpEF. This is an observational study with no study intervention or randomization.
Participants will undergo baseline history and physical, 12-lead EKG, laboratory studies of blood/serum/urine, echocardiography, activity questionnaire, 6 minute walk test, and placement of wearable devices to be worn for up to 14 days (activity monitors, EKG monitor and continuous glucose monitor).
Participants will return after \~14 days of wearing the devices and repeat of physical examination, 12-lead EKG, 6 minute walk test, activity questionnaire. Additionally, participants will undergo magnetic resonance imaging (MRI) of their leg with exercise, cardiopulmonary exercise testing (CPET) and, for those who qualify, magnetic resonance imaging (MRI) of their heart with exercise.
