Filter by:Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are serious diseases with poor prognosis despite recent advances. Currently, pulmonary hypertension (PH) is considered a cell proliferative disorder, which has not been adequately characterized due to the lack of markers. A better understanding of the mechanisms that regulate this proliferative disorder will allow the identification of new therapeutic targets for HP. The objective of the project is to identify cell proliferative processes in severe forms of PH. Patients with PAH (n=20), CTEPH (n=20) and healthy controls (n=20) will undergo characterization of microRNAs (miRNAs) contained within circulating microparticles (MPs) analysis and mitochondrial functionality and FDG-PET to compare cell metabolism in the lungs and the right ventricle between patients and controls.
In this study effect of NHF on pulmonary thermodynamic parameters will studied.
Over the past decade, advancements in therapies available for pulmonary hypertension (PH) have increased life expectancy for those who qualify and receive treatment. Yet, prognostication of these patients has remained a clinical dilemma. The application of the REVEAL registry predictive algorithm provides information about estimated 1-year survival but since invasive measurements from a right heart catheterization cannot easily be repeated, it is not feasible to continually use this longitudinally to assess the disease burden. Simple tests such as BNP has been shown to be very clinically relevant in short -term and long term prognostication and seems to correspond well to the right ventricular failure. Elevated right atrial pressures, and its estimation via IVC measurements predict poor survivorship in a recent retrospective analysis. As clinical measurement of jugular venous pressure is becoming less reliable, we aim to bring point- of-care ultrasound to the outpatient setting. Point of care ultrasound is widely used in the Emergency Department and Intensive Care Unit settings. By measuring estimated right atrial pressure (eRAP) via Inferior Vena Cava (IVC) measurements at outpatient clinic visits we aim to find a correlation with the existing and widely used B-type Natriuretic Peptide (BNP), that is collected at each visit as a part of regular care. These measurements can be followed longitudinally and may aid in prognostication. Data will be collected over the period of 1 year at clinic visits. A composite endpoint (including death, hospitalizations for PH, addition of new PH specific therapy after a stabilization period of 3 months, lung transplant or atrial septostomy) will separately be collected. At the end of the data collection period, clinical data only will be collected for a additional 2 years via phone correspondence, chart review or at regular PH clinic visits.
The aim of this study is to determine the safety and efficiency of Remodulin®（Treprostinil Injection）to reduce the pulmonary arterial pressure and prevent pulmonary hypertension (PH) after Fontan operation with univentricular physiology.
The investigators will investigate the interrelationship of macrophage migration inhibitory factor (MIF) and free T4 in patients with PAH.
Currently, the standard treatment for proximal thromboses lesions responsible for post-embolic pulmonary hypertension, is the surgical thromboendarterectomy. When the ravages are judged too distal or the patient is judged inoperable for a curative surgical gesture, there is no evidence of any therapeutic option, exept for K anti-vitamins for recurrent embolism. Prognosis is then pejorative with a 60% mortality at 5 years. This study propose an alternative treatment for these patients in therapeutic "dead end". This is about applying arterial thrombosis technique to the pulmonary circulation.
This study is looking to see if giving ranolazine to subjects on stable pulmonary hypertension therapies but with right ventricular dysfunction (RVEF <45%) will improve their health by improving right ventricular (RV) function.
This is a prospective, observational, multicenter study conducted during 1 year in adult and paediatric intensive care units equipped with the EZ-KINOX™ system. A maximum of 250 patients (newborns to adults, suffering from Pulmonary Arterial Hypertension (PAH) associated with cardiac surgery or Persistent Pulmonary Hypertension in the Newborn (PPHN) receiving iNO through the integrated delivery and monitoring EZ-KINOX™ system was planned to be included. The study is strictly non-interventional with the aim of describing current practices and therefore did not affect the patient usual management.
In this study, study team aim to i) evaluate the accuracy of 3D IVS curvedness for prediction of RV systolic pressure (RVSP), mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) with RHC; ii) evaluate the usefulness of 3D IVS curvedness for predicting the response to vasodilator challenge with RHC, in patients clinically suspected or known to have primary PH.
In this prospective case-control study, the investigators will evaluate the diagnostic performance of a novel electronic nose (E-nose) for the detection of Pulmonary Arterial Hypertension (PAH). This study is designed to: 1. Assess the performance of the E-nose to discriminate controls from patients with PAH 2. Assess the performance of the E-nose to discriminate between different subtypes of pulmonary hypertension (PH), namely idiopathic PAH, heritable PAH with BMPR2 mutation and chronic thromboembolic PH 3. Assess the performance of the E-nose to discriminate controls from asymptomatic patients with PH who carry BMPR2 mutations.
