Associations Between Helicity/Vorticity and PH Markers
| PH Markers | Helicity | Vorticity |
|---|---|---|
| EF | 0.865 (<0.0001) | 0.478 (0.0029) |
| VVCR | −0.916 (<0.0001) | −0.426 (0.0058) |
| ESV | −0.482 (0.0008) | −0.190 (0.233) |
| EDV | −0.472 (0.0010) | −0.216 (0.174) |
| SV | 0.477 (0.0009) | 0.316 (0.0440) |
| CO | 0.581 (<0.0001) | 0.398 (0.0098) |
| mPAP | −0.584 (0.0008) | −0.408 (0.0309) |
| MPA‐RAC | 0.789 (<0.0001) | 0.577 (<0.0001) |
Correlations are reported as R/ρ values, with corresponding adjusted P values in parentheses. CO indicates cardiac output; EDV, end‐diastolic volume; EF, ejection fraction; ESV, end‐systolic volume; MPA, main pulmonary artery; mPAP, main pulmonary arterial pressure; PH, pulmonary hypertension; RAC, relative area change; SV, stroke volume; and VVCR, ventricular/vascular coupling ratio.
