Cardiac Assessment by PV Loop in IPAH and Scleroderma PAH
This observational study is being done to understand why people with scleroderma can develop pulmonary arterial hypertension (high blood pressure in the lungs, abbreviated PAH) and a weak heart muscle (heart failure). The study will also help the investigators understand why people with PAH from an unknown cause (called idiopathic PAH, or IPAH) can also develop a weakened heart muscle. The response of the right side of the heart or right ventricle (RV) to standard PAH therapy in scleroderma-associated PAH and in IPAH will be assessed. Blood and tissue samples will be collected from research participants during participants' normal ...

Cardiac Function and Exercise Capacity in Pulmonary Arterial Hypertension
Pulmonary Arterial Hypertension is characterized by a progressive increase in pulmonary vascular resistance inducing shortness of breath and exercise intolerance. We aim to correlate cardiac function (evaluated at rest by right heart catheterism and RMN) to exercise capacity (evaluated by endurance time at 75% of maximal workout), in prevalent patients with pulmonary arterial hypertension, and their evolution at three and twelve months.

Cardiopulmonary Toxicity of Thoracic Radiotherapy
Radiotherapy improves locoregional control and survival of thoracic tumour patients. However, the associated exposure of normal tissues, often leads to side effects and possibly even reduces survival. Indeed, there is growing evidence that overall survival after radiotherapy for lung and oesophageal cancer is related to the radiation dose to heart and lungs. This suggests that thoracic radiotherapy causes mortality, which is currently not recognized as radiation-induced toxicity. So the question arises how to explain this treatment-related mortality. Interestingly, Ghobadi et al demonstrated in rats that thoracic irradiation can...

Central China Congenital Heart Disease Associated Pulmonary Arterial Hypertension Cohort Study
The study will recruit and follow up patients for five years patients newly diagnosed with congenital heart disease associated pulmonary arterial hypertension(CHD-PAH) from the investigator's hospital. The main aim of the study is to describe the aetiology, natural history and management practices of CHD-PAH in central China.

Change-a Multi-center Chronic Thromboembolic Pulmonary Hypertension （CTEPH） Database in China
The Change Database is a prospective, observational multi-center disease registry, which will collect data on patients with chronic thromboembolic pulmonary hypertension (CTEPH) in China. The registry will run for approximately 5 years. It aims to illustrate the epidemiology, management and longterm outcomes of CTEPH.

Clinical Study of Balloon Pulmonary Angioplasty for Patients With Chronic Thromboembolic Pulmonary Hypertension
Chronic thromboembolic pulmonary hypertension (CTEPH) is the fourth group of pulmonary hypertension (PH) according to clinical classification. Pulmonary endarterectomy（PEA) is the preferred treatment for patients with CTEPH, however, PEA has its limitations, it only applies to the thrombi in the main, lobar, or segmental pulmonary arteries for patients with CTEPH, and the postoperative residual PH is found to be of high percentage. With the development of interventional techniques, balloon pulmonary angioplasty (BPA) has been used to treat chronic thrombotic pulmonary hypertension (CTEPH) with favorable results and has been...

Clinical Study to Compare the Efficacy and Safety of Macitentan and Tadalafil Monotherapies With the Corresponding Fixed-dose Combination Therapy in Subjects With Pulmonary Arterial Hypertension (PAH)
Combination therapy in pulmonary arterial hypertension (PAH) has been the subject of active investigation for more than a decade, with the benefit of targeting different pathways known to be involved in the pathogenesis of the disease. Adherence to prescribed therapy has an impact on clinical outcomes. Reducing the pill/tablet count and frequency has a major impact on patients' adherence to therapies and therefore the observed clinical outcomes. One way to simplify treatment is to use fixed-dose combination (FDC) products that combine multiple treatments targeting different pathways into a single tablet. This study aims to...

Clinical Trial to Investigate Safety and Efficacy of Edoxaban in Patients With CTEPH (KABUKI)
This is phase III trial to evaluate whether edoxaban, a direct factor Xa inhibitor, is noninferior to warfarin in preventing worsening of chronic thromboembolic pulmonary hypertension (CTEPH).

Comparison of Vasodilator Response of Inhaled Epoprostenol and Inhaled Nitric Oxide
The overarching goal of this study is to examine the acute vasoreactive response to both inhaled nitric oxide and inhaled epoprostenol across both traditionally and non-traditionally interrogated phenotypes in PH, and to further characterize the relationship of vasoreactivity to disease severity and PH phenotype.
