About
The objective of this study is to determine whether participation in an 8-week structured cardiac rehabilitation program can increase cardiorespiratory fitness in patients with atrial fibrillation.
Full description
The study is a randomized, prospective single center study to assess the utility and efficacy of cardiac rehabilitation in patients with AF. All participants will receive the same medical care and standard baseline education which includes an hour long one on one session with a nutritionist.
Participants will also receive the guide book, Lifestyle Guide to Healing the Heart, at their baseline visit as part of their education
After obtaining informed consent to participate in the study and signing a consent form to participate in the Phase 3 cardiac rehabilitation program, participants will undergo a baseline assessment of their functional status using the functional capacity NuStep test. The NuStep test will be conducted at the Valley Hospital at baseline and after 8 weeks using the NuStep TRS 4000 machine - a stationary bike machine that also engages one's arms by pushing and pulling arm handles. Participants will sit in the NuStep machine and bike on level 4 (a low to moderate level) for 6 minutes, if possible. However, participants will be encouraged to step as quickly as possible during this time period. Participants will be asked about any discomfort before, during and after the test. The participant's METS are calculated directly by the machine based on the watts while exercising.
The degree of improvement of the participant's METS over the course of the 8-week program will produce a greater understanding of the effect of a structured cardiac rehabilitation program on cardiorespiratory fitness.
Following this baseline assessment, participants will then be randomized to undergo usual care or an 8-week (24-session) Phase 3 cardiac rehabilitation program at the Valley Health System Center for Health & Wellness in Mahwah. Eight weeks later, participants will undergo repeat assessment of functional status.
In addition, participants will be administered the Atrial Fibrillation Effect on Quality-of-life (AFEQT) survey at baseline, 6-months and 12-months later.
Patients will also undergo a 1-week Zio XT Holter monitor at the same time points (baseline, 6-months and 12-months). The Zio XT Holter monitor is a small, discreet comfortable patch that sticks on a participant's chest to test for any arrhythmias, such as AF duration and burden. The Zio XT Holter monitor will be available through commercial (HIPAA-compliant) remote monitoring portals and will not be stored locally in Valley Health System. However, in the future this may change and the Zio XT Holter monitor data will be stored as part of the participant's electronic medical record.
