The symptoms and clinical findings in CTEPH are comparable to those in pulmonary arterial hypertension (PAH).
The main problem lies, as in pulmonary hypertension, in that the symptoms are very uncharacteristic and that the CTEPH is not recognized, due to its relative rarity.
- If increasing breathing problems are present under stress, the lung function test and lung X-ray are “normal” and a coronary disease has been ruled out, pulmonary hypertension should definitely be considered.
- In addition, general tiredness, weakness in the lower extremities or even depression can also be present.
- Dull pain occurring in the breast can point erroneously to coronary disease, and dizziness or even unconsciousness can mimic disorders of the nervous system.
- A dry cough or hemoptysis are rather rare.
- In the advanced stages, accumulation of water in the body can lead to swelling and weight gain.
