Key result
Upright position during right heart catheterization resulted in higher resting pulmonary vascular resistance compared to supine position (4.1 vs 3.9 Wood units, P<0.001).
Why the study?
The study was conducted to determine how body position influences resting and exercise pulmonary hemodynamics in patients assessed for pulmonary hypertension.
Does upright versus supine position affect resting and exercise pulmonary hemodynamics in patients assessed for pulmonary hypertension?
Observational (n=483)
Does upright versus supine position affect resting and exercise pulmonary hemodynamics in patients assessed for pulmonary hypertension?
Absolute Event Rate: 4.1% vs 3.9%
p-value: p=<0.001
Body position significantly affects pulmonary hemodynamics, with higher pulmonary vascular resistance observed in the upright position, highlighting the need to standardize and report position during right heart catheterization.
No takes yet. Share an insight, caveat, or question.
Body position warrants consideration in PVR interpretation during RHC; leaves open whether standardization is needed in future protocols.
Berlier et al. (2022) conducted an observational in Suspected pulmonary hypertension (n=483). Upright position vs. Supine position was evaluated on Resting pulmonary vascular resistance (Wood units) (p=<0.001). Upright position during right heart catheterization resulted in higher resting pulmonary vascular resistance compared to supine position (4.1 vs 3.9 Wood units, P<0.001).
