Here is the translation: **What Is Chronic Thromboembolic Pulmonary Hypertension?** Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare form of pulmonary hypertension that occurs when blood clots block blood vessels in the lungs. **Symptoms of CTEPH** Symptoms may include: * Chest pain or shortness of breath, especially during physical activity. * Coughing up yellow mucus or sputum. * Wheezing or feeling like you can't catch your breath. * Swollen legs due to fluid retention (edema). **Diagnosis and Tests** CTEPH is diagnosed through a combination of tests, including: * Lung ventilation-perfusion scan (V/Q scan) * Pulmonary angiogram * Pulmonary function tests * Transthoracic echocardiogram (TTE) * Right heart catheterization * CT pulmonary or digital subtraction angiography * Exercise stress test **Management and Treatment** CTEPH is typically treated with a procedure, either: * Pulmonary endarterectomy: an open surgical procedure to remove blood clots from lung arteries. * Pulmonary balloon angioplasty: a procedure that uses tiny balloons at the tip of long tubes (catheters) to push aside scar tissue and open up narrowed arteries. **Prevention** While CTEPH is not preventable, there are steps you can take to lower your risk: * Quit smoking or avoid tobacco. * Take good care of your lungs through regular exercise and healthy habits. **Outlook/Prognosis** With treatment, many people with CTEPH have an excellent prognosis. However, anxiety and depression are common in these patients, especially those who are not eligible for curative treatment. Your healthcare provider can help you manage these issues. **Living with CTEPH** When living with CTEPH: * You will need to take blood thinners for the rest of your life. * Avoid foods high in vitamin K, such as soy and broccoli, if taking warfarin. * Engage in light exercise, like walking, to maintain strength and overall health. * Consider a medically supervised exercise program (pulmonary rehabilitation) recommended by your healthcare provider.
