Filter by:This is an open-label, multicentre study evaluating the effect, safety and tolerability of the two regioisomers 1-(nitrosooxy)propan-2-ol and 2-(nitrosooxy)propan-1-ol (PDNO) infusion given to COVID-19 patients with acute pulmonary hypertension (aPH) and/or acute cor pulmonale (ACP).
This study will determine the feasibility of a mobile application-based home exercise rehabilitation program for patients with pulmonary hypertension.
In univentricular hearts, selective lung vasodilators such as phosphodiesterase type 5 (PDE5) inhibitors would decrease pulmonary resistance and improve exercise tolerance. However, the level of evidence for the use of PDE5 inhibitors in patients with a single ventricle (SV) remains limited. the investigators present the SV-INHIBITION study rationale, design and methods.The SV-INHIBITION trial is a nationwide multicentre, randomised, double blind, placebo-controlled, phase III study, aiming to evaluate the efficacy of sildenafil on the ventilatory efficiency during exercise, in teenagers and adult patients (>15 y.o.) with a SV. Patients with pulmonary arterial hypertension (mean pulmonary arterial pressure (mPAP) > 15 mmHg and trans-pulmonary gradient > 5 mmHg) measured by cardiac catheterisation, will be eligible. The primary outcome is the variation of the VE/VCO2 slope, measured by a cardiopulmonary exercise test, between baseline and 6 months of treatment. A total of 50 patients are required to observe a decrease of 5 ± 5 points in the VE/VCO2 slope, with a power of 90% power and an alpha risk of 5%. The secondary outcomes are: clinical outcomes, 6 minute walk test, SV function, NT Pro BNP, VO2max, stroke volume, mPAP, trans-pulmonary gradient, SF36 quality of life score, safety and acceptability. This study aims to answer the question whether PDE5 inhibitors should be prescribed in patients with a SV. This trial has been built focusing on the 3 levels of research defined by the WHO: disability (exercise tolerance), deficit (SV function), and handicap (quality of life).
The ballistocardiography (BCG) and the seismocardiography (SCG) are old techniques recording the vibrations at the skin level generated by the acceleration and displacement of the blood and cardiac mass at each cardiac contraction. The former records the acceleration near the subject's center of mass, the latter at the local chest wall. So far, the unclear physiological origin of those acceleration signals has led to important ambiguities in their scientific and clinical interpretation. Therefore, several ongoing studies would aim to highlight the physiological genesis of those acceleration-induced signals. Indeed, the main objective of this study is to correlate the BCG and SCG signals recorded at the body surface with several haemodynamic parameters recorded invasively during a cardiac catheterisation, pulmonary pressure, wedge pressure, cardiac output to cite a few.
This is an open-label, single-center study to examine distinguishing features of the structure and function of the oral and gut microbiome in volunteers with PH in the breakdown of oral nitrate and effect on hemodynamics.
This study aims to evaluate cardiopulmonary interactions in patients with heat failure
The purpose of this study is to evaluate the efficacy and safety of the combination of ambrisentan and tadalafil in reducing mPAP to below 35mmHg in patients with moderate to severe Portopulmonary Hypertension (POPH) as a means to candidacy for liver transplantation.
The development of disease-targeted drugs for the treatment of pulmonary arterial hypertension (PAH) has significantly improved within the last years. Combining drug products with different mechanisms of action such as Endothelin-Receptor-Antagonists (ERAs) and Phosphodiesterase-Type-5-inhibitors (PDE-5-Inhibitors) has become increasingly important for the treatment of PAH. Recently, the results of the AMBITION study reported that an upfront combination treatment of ambrisentan and tadalafil immediately after diagnosis leads to a delayed disease progression. On the other hand, the sequential combination of bosentan and sildenafil did not show a similar positive clinical effect and this was attributed to a negative clinically relevant pharmacodynamic drug-drug interaction. Although, recent guidelines have extrapolated that initial upfront combination treatment follows a class effect in terms of efficacy and safety, there is an imperative need to support this notion with other combinations of ERAs and PDE-5-Inhibitors.
This is a multicenter, single-arm trial to evaluate the safety and efficacy of inhaled treprostinil in subjects with pre-capillary pulmonary hypertension (PH) associated with Chronic Obstructive Pulmonary Disease (COPD).
The goal of this study is to elucidate the relationship between myocardial right ventricular triglyceride content (steatosis) and right ventricular dysfunction in participants with pulmonary hypertension, and investigate reversibility of this phenotype with omega-3 fatty acid treatment.
