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.
Characteristics of Pulmonary Vascular Changes in Patients With Kidney Transplantation
The aim of the study is to investigate pulmonary hemodynamics at rest and during exercise in patients before and after kidney transplantation.
Clinical Study of Adipose Derived Mesenchymal Stem Cells for Treatment of Pulmonary Arterial Hypertension
Pulmonary arterial hypertension is a disease characterised by pathological changes in the pulmonary arteries leading to a progressive increase in pulmonary vascular resistance and pulmonary artery pressure. Right ventricular failure is the main cause of death in patients with pulmonary arterial hypertension, and the ability of the right ventricle to adapt to the progressive increase in pulmonary vascular resistance associated with changes to the pulmonary vasculature in pulmonary arterial hypertension is the main determinant of a patient's functional capacity and survival.Mesenchymal stem cells (MSCs)are a subset of adult stem cells...
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...
Combined Use of Radiofrequency-ablation and Balloon-septostomy in the Creation of a Stable Inter-atrial Communication
Though graded balloon-atrial-septostomy (BAS) has been accepted as an effective palliative therapy for severe pulmonary arterial hypertension, spontaneous closure of septostomy is not uncommon. Radiofrequency-catheter-ablation (RFA), which has the potential to cause irreversible damage around the rim of created inter-atrial communication, might contribute to prevent the spontaneous closure. In patients with severe pulmonary arterial hypertension, the combined use of RFA and BAS (CURB) is investigated to create a stable inter-atrial communication.
COMPERA / COMPERA-KIDS
In view of the manifold options for mono- and combination therapy that have now emerged for patients with pulmonary (arterial) hypertension (PH/PAH), controlled clinical trials can only provide part of the information needed for optimal management. In order to gather adequate data on PAH/PH treatment in routine clinical care, the ongoing COMPERA registry prospectively documents consecutive patients with newly initiated treatment of PAH/PAH since May 2007. The internet-based registry fulfills high quality standards through several measures (planned minimum centre contribution of at least 10 patients per year, automated plausibility checks ...
Computerized Decision Support to Increase Detection of Chronic Thromboembolic Pulmonary Hypertension in Patients With Prior Pulmonary Embolism
To address the knowledge gap that exists among providers resulting in underdiagnosis of chronic thromboembolic pulmonary hypertension (CTEPH), the investigators have devised this 400-patient single-center Quality Improvement Initiative in the form of a randomized controlled trial of an EPIC Best Practice Advisory (BPA) on-screen alert versus no notification to increase echocardiographic screening for CTEPH and the diagnosis of CTEPH in patients with prior pulmonary embolism (PE) and symptoms/signs suggestive of pulmonary hypertension or recent pulmonary testing suggesting unexplained respiratory symptoms at 3 months. Aim #1:...
COVID-19 Pneumonia: Pulmonary Physiology, Health-related Quality of Life and Benefit of a Rehabilitation Program
The pathophysiological processes involved in COVID-19 pneumonia are not fully understood. Specific alterations of the airways, lung parenchyma and pulmonary vascular tree could explain a severe ventilation/perfusion heterogeneity resulting in severe hypoxemia during the active phase of the disease. Additional skeletal muscle impairment related to systemic inflammation may also explain persisting symptoms in the follow-up phase. The first aim of the present project is to explore these different processes by evaluating the impact of the COVID-19 pneumonia on exercise capacity, pulmonary function and perfusion by a physiological and...
Database for Clinical and Anamnestic Data in Pulmonary Hypertension
Pulmonary hypertension (PH) is defined as a pulmonary arterial mean pressure (meanPAP) ≥ 25 mmHg measured in the right heart catheterization. There are different forms of PH defined in the classification of Dana Point 2008. PH is diagnosed with right heart catheterization but there are other non invasive methods which can be used for screening like the echocardiography, stress echocardiography and cardio pulmonary exercise testing. In the diagnosis process and in the follow up of PH patients biomarkers like NTproBNP are helpful. There are no specific biomarkers for the disease which can make the diagnosis process easier and...
