Factor	association between RV and pulmonary dynamics with the distance walked in 6 minutes: Right atrial pressure
Description	Higher PACi, lower systolic pulmonary artery pressure, lower PVRi, increased cardiac output, and longer pulmonary ejection time were associated with a longer distance walked in 6 minutes. Both higher PVRi and lower PACi were found to be independently associated with shorter distance walked in 6 minutes.
Biomarker	NA
Classification	Z (combined factor - combined factor)

Association
Application	risk assessment
Objective	Therefore, the objectives of the current study were to investigate the relation of PAC to PVR, 6-minute walk distance, and freedom from lung transplantation or death in children with PAH.
p Value	0.01
Conclusion	Higher PACi, lower systolic pulmonary artery pressure, lower PVRi, increased cardiac output, and longer pulmonary ejection time were associated with longer distance walked in 6 minutes. Both higher PVRi and lower PACi were found to be independently associated with shorter distance walked in 6 minutes.
Risk Factor	unknown
