Prevention & lipidsCohort study
Phase angle measured by bioelectrical impedance analysis as a predictor of exercise capacity in patients undergoing late-recovery phase cardiac rehabilitation
- Retrospective cohort study
Authors' conclusion
This study is the first to provide evidence of the significant correlation between PhA and exercise capacity in patients undergoing the late-recovery phase of CR.
Study context
- Population
- Patients undergoing late-recovery phase cardiac rehabilitation (CR)
- Participants
- 107 patients
- Outcome
- Association between phase angle (PhA, bioelectrical impedance analysis) and exercise capacity (peak V̇O2 by cardiopulmonary exercise testing)
- Follow-up
- Before and after CR
Main finding
As reported in the abstract
PhA and peak V̇O2
Correlation of phase angle (PhA) with post-CR peak V̇O2 (r)
0.603, P < 0.01
Observational data: associations, not effects.
Further findings
Change in PhA after CR · before to after CR
- PhA increase in men
- 4.69-4.89
- PhA increase in women
- 4.06-4.47
- P < 0.05 for both
