Symptoms and Diagnosis
Most patients present with fatigue, decreased exercise tolerance, shortness of breath, chest tightness, dizziness, bloating, or swelling in the legs. Sometimes patients have symptoms for years before a cause is identified.
Common Work up – Patients may have one or more of the following tests:
- Physical exam
- 6 Minute Walk Test to evaluate exercise capacity
- Echocardiogram (ultrasound of the heart) to evaluate heart function.
- CT scan of the chest to look for scarring or emphysema.
- Pulmonary function testing to look for COPD or low lung volumes.
- Blood Tests
- Sleep study to evaluate for sleep apnea.
- V/Q scan to look for chronic blood clots.
- Right heart catheterization is performed to measure the pressures in the heart and lung blood vessels and sometimes pulmonary angiography to visualize the lung blood vessels themselves.
