This clinical trial is focused on studying the effects of different anticoagulant medicines in patients with Chronic Thromboembolic Pulmonary Hypertension (CTEPH) and Chronic Thromboembolic Disease (CTED) without pulmonary hypertension. These conditions involve blood clots in the lungs that can lead to increased blood pressure in the lung arteries. The trial will compare the safety and effectiveness of two types of blood-thinning medications: Direct Oral Anticoagulants (DOACs) and Vitamin K Antagonists (VKAs). The medications being studied include Eliquis (apixaban), Fenprocoumon Sandoz (phenprocoumon), Lixiana (edoxaban), Acenocoumarol CF (acenocoumarol), Pradaxa (dabigatran etexilate), and Xarelto (rivaroxaban).
The purpose of the study is to evaluate how these medications perform in patients undergoing a procedure called Balloon Pulmonary Angioplasty (BPA). This procedure is used to open up blocked blood vessels in the lungs. The study will look at the occurrence of bleeding and lung injury within 24 hours after the procedure. Participants will receive one of the medications or a placebo, and their health will be monitored to see how well the medications work and how safe they are.
The study will take place over a period of time, with participants receiving treatment for up to 30 days. During this time, researchers will collect data on any complications, such as bleeding or lung issues, as well as other health outcomes like allergic reactions, kidney problems, and hospitalizations. The goal is to better understand which medication is most effective and safe for patients with CTEPH or CTED undergoing BPA.
