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...

Carnitine Consumption and Augmentation in Pulmonary Arterial Hypertension
In preparation for a future mechanistic study, investigators now propose to test the specific hypothesis that carnitine consumption is not reduced in PAH, that plasma carnitine levels are stable over time in PAH and that carnitine supplementation in PAH can increase plasma carnitine and thereby delivery of carnitine to the RV and possibly improve RV function. Investigators propose three aims in humans to test this mechanistic hypothesis, 1) Measure the oral consumption of carnitine in human PAH. This aim will use food diaries and carnitine supplement use questionnaires in PAH patients to test the hypothesis that carnitine ...

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...

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.

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 ...

COMPression of Left Main coRonary artEry in patientS With Pulmonary Arterial Hypertension aSymptomatIc fOr aNgina
The prevalence of critical ab extrinsic compression of left main coronary artery (LMCA) is very high in patients with pulmonary arterial hypertension (PAH) symptomatic for angina (up to 40% according to a recent study of 121 patients with PAH). The element that most of all correlates with the degree of coronary stenosis is the diameter of the pulmonary artery (PA). In particular, a diameter ≥ 40 mm has a sensitivity of 83% and a specificity of 70% in patients with angina. Critical stenosis of LMCA is a risk factor for sudden death and in these condition percutaneous coronary angioplasty with stent implantation has proven to be a safe...

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:...
