This system grades PH severity according to the patient’s functional status, by linking symptoms with activity limitations. WHO-FC remains a powerful predictor of outcomes in patients with PAH.
| WHO - FC | Description |
|---|---|
|
I |
Patients with PH in whom there is no limitation of usual physical activity; ordinary physical activity does not cause increased dyspnoea, fatigue, chest pain, or presyncope. |
|
II |
Patients with PH who have mild limitation of physical activity. There is no discomfort at rest, but normal physical activity causes increased dyspnoea, fatigue, chest pain, or presyncope. |
|
III |
Patients with PH who have a marked limitation of physical activity. There is no discomfort at rest, but less than ordinary activity causes increased dyspnoea, fatigue, chest pain, or presyncope. |
|
IV |
Patients with PH who are unable to perform any physical activity at rest and who may have signs of right ventricular failure. Dyspnoea and/or fatigue may be present at rest, and symptoms are increased by almost any physical activity. |
