Chronic Thromboembolic Pulmonary Hypertension (CTEPH)
Chronic Thromboembolic Pulmonary Hypertension (CTEPH) Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare form of high blood pressure affecting the lungs. It is caused by blood clots in the lung vessels that get stuck, clog the arteries and eventually form scar tissue. This scar tissue narrows the lung’s blood vessels, making it difficult for blood to pass through. CTEPH is challenging to diagnose, often leading to delayed or missed diagnoses.
