Heart rate recovery after orthostatic challenge and cardiopulmonary exercise testing in older individuals: prospective multicentre observational cohort study
Authors' conclusion
Prognostically significant heart rate recovery after exhaustive exercise is characterised by quantitative differences in heart rate recovery after orthostatic challenge.
Study context
- Population
- Older individuals scheduled for cardiopulmonary exercise testing (CPET) as part of routine carecompleted both tests
- Participants
- 87 individuals
- Exposure
- HRR after orthostatic challenge vs HRR after maximal exercise
- HRRexercise ≤12 beats min-1n = 27reference
- HRRexercise >12 beats min-1n = 60
- Outcome
- Correlation between mean heart rate change every 10 s for 1 min after peak heart rate on standing and after exercise
- Follow-up
- 1 min after peak heart rate
Main finding
As reported in the abstract
Correlation of mean heart rate change after standing and after exercise
- Significantly correlated (R2)
- 0.81
- P
- P<0.0001
Observational data: associations, not effects.

Peak VO2 with slower HRRorthostatic

HRRorthostatic by HRRexercise category
- HRRorthostatic unchanged in individuals with HRRexercise ≤12 beats min-1, lower when HRRexercise >12 beats min-1
