Selexipag is available in many countries for the treatment of pulmonary arterial hypertension (PAH). Due to the similarities between PAH and chronic thromboembolic pulmonary hypertension (CTEPH) and the observed efficacy of other PAH medicines in CTEPH, it is believed that selexipag could benefit to patients with CTEPH. This study aims to assess the efficacy and safety of selexipag in subjects with inoperable or persistent/recurrent CTEPH.
Some patients who have blood clots come down with a life-threatening condition known as Chronic Thromboembolic Pulmonary Hypertension (CTEPH), which is high blood pressure only in the arteries of the lungs. This study seeks to understand more about the genetics causes of CTEPH by obtaining blood samples and examining family histories.
This research study wants to find markers in the blood that may help to predict a patient's future risk of developing a disease called CTEPH. The study also wants to see if active monitoring for signs and symptoms of CTEPH after a pulmonary embolism (a blood clot in the lungs) can improve the diagnosis of CTEPH. Patients who enroll in this study will have periodic blood draws and clinic and/or phone follow-up to monitor for signs and symptoms of CTEPH. Patients' medical records will also be reviewed for information related to pulmonary embolisms and/or CTEPH.
Measurement of the endtidal carbon dioxide by capnography to exclude or to ensure the diagnosis pulmonary hypertension. The aim of the study is to obtain an endtidal carbon dioxide cut-off value for the diagnostic algorithm for pulmonary hypertension as an easily measurable and cheap diagnostic tool in patients with suspicion of pulmonary hypertension.
There will be assessment of patients after acute pulmonary embolism for the development of CTEPH
This is a randomised, double-blind, placebo-controlled, multicentre, multinational, prospective study in patients with operable chronic thromboembolic pulmonary hypertension (CTEPH) prior to pulmonary endarterectomy (PEA) with high preoperative pulmonary vascular resistance (PVR). Patients will be randomised in a 1:1 ratio to receive riociguat or matching placebo for 3 months before undergoing PEA. The primary objective of this study is to assess the efficacy of riociguat on preoperative PVR compared to placebo in patients with operable CTEPH.
The International Balloon Pulmonary Angioplasty (BPA) Registry is a prospective, multi-center, long-term observational project. Scheduled to start data collection in Q4 2017, the registry will run for approximately four years with a follow-up time for each patient of at least two years. Its primary objective is to investigate the efficacy and safety of BPA intervention in patients with chronic thromboembolic pulmonary hypertension (CTEPH) not amenable to pulmonary endarterectomy (PEA).
Chronically elevated pulmonary pressures do not immediately result in right ventricular failure. During the initial period of exposure, the RV adapts to the increased afterload by altering its metabolism and morphology so as to meet the increased work requirement. Several, interconnected adaptive mechanisms have been proposed, including myocyte hypertrophy, a switch in the primary fuel used for ATP generation, increased angiogenesis, and decreased production of mitochondrial reactive oxygen species. While adaptation is initially successful in many cases, it is temporary, and after an uncertain period of time, the ventricle begins to fail. This transition from a compensated to decompensated state is difficult to predict clinically, and patients with different etiologies of CPOS progress to overt RV failure over significantly different time periods. This variability hinders the implementation of treatments that are tailored to a specific disease stage.
The collected data from the Zurich Registry for pulmonary Hypertension (PH) are evaluated in a retrospective analysis. This study examines the number of patients and their exact diagnoses who are treated at the University Hospital of Zurich and potentially other participating in the Zurich Registry. Other demographic parameters such as age, gender and body-mass-index are also part of the evaluation. Furthermore, the analysis will focus on the newest guidelines on PH. Therefore, it will be checked how many patients would fulfill the therapeutic goals in terms of New York Heart Classification (NYHA), 6-minute walk distance, sign of right heart failure and N-terminal pro-brain-natriuretic peptide(NTproBNP). Additionally, the study examines on how the patients are treated. Despite the different kind of Drugs, the focus lies on the combination therapy (single, double, triple) and the impact the therapy had on the patients.
The objective of the present study is to assess blood coagulation disorders in patients with Pulmonary Arterial Hypertension and Chronic Thromboembolic Pulmonary Hypertension. The investigators aim to evaluate any possible coagulation abnormalities related to the patients' primary disease and any possible effects the pulmonary hypertension- specific therapy may have on hemostasis.
