Filter by:Exercise capacity (EC) is limited in pulmonary arterial hypertension (PAH) by impaired right ventricular (RV) function and inability to increase stroke volume (SV). Disease targeted therapy, increases EC by improving SV. Additional factors may contribute to exercise limitation: - Peripheral and respiratory muscle dysfunction - Autonomic dysfunction - An altered profile of inflammation - Mitochondrial dysfunction. The enhancement of EC achieved pharmacologically may therefore be limited. Exercise training in PAH improves EC and quality of life (QOL). The changes in physiology responsible for this improvement are not clear. Patients with PAH stable on optimal oral therapy, but not meeting treatment goals, will be enrolled in a 30-week randomised exercise training program. One arm will undertake training for 15 weeks (3 weeks residential, 12 outpatient), the other will receive standard care for 15 weeks then 15 weeks training. Aims: 1. Demonstrate that exercise training can enhance EC and QOL when added to optimal drug therapy a UK PAH population. 2. Explore mechanisms of exercise limitation and factors that improve with training, assessing: - Cardiac function - Skeletal muscle function - Autonomic function - Respiratory muscle strength - Serum and muscle profile of inflammation Primary outcomes (15 weeks) 1. 6 minute walk distance 2. QOL 3. RV ejection fraction
The main purpose of this clinical trial is to examine the feasibility and effects of fulvestrant in post-menopausal women with pulmonary arterial hypertension (PAH). The study will evaluate how well the drug is tolerated. The study will evaluate changes in circulating hematopoietic progenitor cells, plasma hormone levels, NT-proBNP, and other plasma biomarkers after the administration of fulvestrant. Changes in tricuspid annular plane systolic excursion, stroke volume index, right ventricular fractional area change, and other echo parameters after fulvestrant administration will be evaluated as well as changes in distance walked in six minutes.
To demonstrate the effectiveness of riociguat as replacement of phosphodiesterase-5 inhibitors (PDE-5i) therapy in pulmonary arterial hypertension (PAH) patients
The purpose of this study is to determine the prognostic value of echocardiographic parameters in comparison with clinical and hemodynamic parameters in pulmonary arterial hypertension (PAH). A secondary purpose of this study is to analyze the disease evolution after 3 to 6 months. In pulmonary fibrosis it has been demonstrated that the variation of clinical and paraclinical parameters between 2 examinations has a prognostic interest. In this study the prognostic value of variation of some echocardiographic parameters between initial examination and echocardiography after 3 or 6 months will be evaluated. Another secondary purpose is to create a common database for Pneumology, Cardiology and Epidemiology departments with prospective registration of new cases of PAH and follow of patients under treatment.
The investigators will investigate the interrelationship of macrophage migration inhibitory factor (MIF) and free T4 in patients with PAH.
The purpose of the study is to evaluate the safety and tolerability of a rapid dose titration regimen of subcutaneous Remodulin® therapy in patients with PAH.
This study is collecting post-marketing information on the safety and effectiveness of Ventavis under the routine clinical practice for patients with PAH
Pulmonary hypertension (PHT) patients often receive long term oral anticoagulants. If the indication is strong, in the secondary chronic thrombo-embolism pulmonary hypertension (CTE-PHT) prevention, the frequent prescription (50 to 90% of patients) contrasts with their low level of proof in the PHT. Last but not least, anticoagulants are known to be the principal cause of iatrogenic hospitalization (major bleeding). In this study, patients are all followed during one year, to determine the annual frequency of major bleedings (according to the International Society on Thrombosis and Haemostasis (ISTH) international definition). Each event notified is validated by an independent committee for clinical events.
HYPID-2 study is an extension of HYPID study (NCT01443598) : HYPID-2 is also an observational and prospective study of patients with interstitial lung disease and pre capillary hypertension diagnosed by right heart sided catheterization. It concerns only incident patients (i.e patients included within 6 months after PH diagnosis) whereas HYPID concerned prevalent and incident cases. The primary aim is the same than HYPID : identify prognostic factors
The purpose of this study is to use non-invasive imaging to determine the metabolic phenotype of the right ventricle in patients with pulmonary arterial hypertension across a spectrum of disease severity.
