Filter by:The purpose of this study is to (1) quantify cardiovascular anatomy and physiology using magnetic resonance imaging under both resting and exercise conditions in patients who have congenital heart disease and in age-matched normal volunteers, (2) use computer models to reproduce and simulate blood flow in these patients, and then (3) to combine the imaging data and computer models to estimate values which cannot be directly measured and to predict physiological changes induced by exercise and medical or surgical therapies.
Pulmonary Hypertension (PH) is a hemodynamic and physiopathological condition that is defined as an increase in mean pulmonary artery pressure ≥25 mmHg when measured at rest. PH often progresses to heart failure and premature deaths. PH is a progressive disease that has many causes, which can affect people of all ages, is characterized by shortness of breath, reduced exercise tolerance, psychological distress and tiredness and reduced quality of life. Surveys of SF-36, 'Nottingham Health Profiles' and 'Minnesota Life with Heart Failure' surveys are routinely performed in PH clinically. However, none of the questionnaires are specific to pulmonary hypertension, so they are incomplete in determining the condition of the disease and the patients. There is no Turkish questionnaire for patients with pulmonary hypertension and other surveys used are inadequate in determining the condition of the patient and the patient since they are not specific to the disease. The aim is to provide a Turkish questionnaire that is specific to pulmonary hypertension in the literature.
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.
The objective of this exploratory study is to examine the utility of high resolution computed tomography (HRCT) to measure changes in functional pulmonary imaging parameters as a function of long term iNO administrationusing the device INOpulse for 4 weeks in relation to Patient Reported Outcome (PRO) and exercise tolerance in subjects with WHO Group 3 PH associated with COPD on LTOT. Changes from baseline to 4 weeks of pulsed iNO and after 2 weeks of withdrawal from pulsed iNO will be evaluated.
The current data on the incidence of pulmonary hypertension (PH) are very variable, depending on the different studies designs. There are no data on the prognostic of PH in patients with asymptomatic pulmonary thromboembolisms (PT), neither paucisymptomatic PH, in which without a prospective follow-up would be underdiagnosed. We thought that the prognosis of both clinical forms (PT with or without symptoms) would be similar. The objective of this study is know the real incidence of pulmonary hypertension (PH) post symptomatic and asymptomatic pulmonary thromboembolic (PT).
The study will investigate the relation between erythrocyte glutamine/glutamate ratio and pulmonary hypertension risk in Egyptian thalassemic children in Assiut University Children Hospital
The purpose of the Phase 2a study is to: 1) demonstrate that the estimated VentaProst dose is safe and equivalent in effect to a dose administered via epoprostenol aerosolization by the current off-label-use practice; and 2) demonstrate that an optimum effect can be rapidly obtained with VentaProst titration.
Hemodynamic measurements obtained during pulmonary artery catheterization are essential for the diagnosis and classification of pulmonary hypertension. Traditionally, right heart catheterization (RHC) is done in the supine position. Cardiac output is known to change significantly based on position, due to the effects of gravity on venous return. There has not been a systematic investigation into these postural effects on pulmonary arterial pressures nor their effect on the diagnosis of pulmonary hypertension. It is our intent to study the differences in measurements obtained during RHC when the patient is supine, seated, and standing.
This study is being conducted to determine whether patients with advanced pulmonary hypertension when treated with cardiac resynchronization therapy improve hemodynamically and/or receive clinical benefit.
This extended access study will assess the long-term safety and tolerability of bardoxolone methyl in qualified patients with pulmonary hypertension (PH) who previously participated in controlled clinical studies with bardoxolone methyl.
