Moderate intensity exercise in pregnant patients with cardiovascular disease: A pilot study
Authors' conclusion
This pilot study of moderate intensity exercise in pregnant individuals with pre-existing CVD demonstrated that patients with CVD were not able to increase their HR during exercise throughout pregnancy compared to those in the control group.
Study context
- Population
- Pregnant patients with and without pre-existing cardiovascular disease (CVD) undertaking a moderate intensity exercise regimen
- Exposure
- Moderate intensity exercise in pregnant patients with CVD vs without CVD
- Outcome
- Doppler umbilical artery S/D ratio
- Follow-up
- 32–34 weeks' gestation
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Umbilical artery S/D ratio
- Umbilical artery S/D ratio normal in both groups
Observational data: associations, not effects.
Secondary outcomes
Exercise intensity (ability to increase HR with exercise over resting HR 1 h prior), at baseline · study baseline
P < 0.001
Daily steps during pregnancy
- CVD walked on average 539 fewer steps per day than control
Resting HR
- Resting HR increased in both groups up to 30 weeks' gestation
- 30
Safety
- No differences in adverse events between groups
