Table 6. Hemodynamic parameters measured during RHC, if available.
| Parameter | Class of recommendation | Remarks |
|---|---|---|
| RAP | I | |
| CO/CI | IIa (see remarks) | By thermodilution (or by the Fick method in cases of systemic-to-pulmonary shunts) |
| MvO2% | IIa | |
| PVR | I | Needed for the diagnosis of PAH |
| mPAP | See remarks | For diagnostic purpose: Class of recommendation I |
| For prognostic purpose: Class of recommendation IIb | ||
| PAWP | I (see remarks) | In case of inaccurate wedging, LVEDP should be measured |
| Vasoreactivity | See remarks | Class of recommendation I in IPAH |
| Class of recommendation IIa in CHD-PAH and CTEPH | ||
| Class of recommendation IIb in other forms of PH |
