4. Chronic Thromboembolic Pulmonary Hypertension (CTEPH)

Chronic Thromboembolic Pulmonary Hypertension (CTEPH) is a serious condition where blood clots that have formed in the lungs don't dissolve and lead to high blood pressure in the pulmonary arteries. This increased pressure makes it harder for the heart to pump blood through the lungs, causing symptoms like shortness of breath, fatigue, and chest pain. Unlike other types of pulmonary hypertension, CTEPH can often be treated surgically or with medication to improve blood flow and pressure, offering hope for patients who are diagnosed with this condition. Early detection and intervention are crucial for better outcomes.
