Filter by:Pulmonary hypertension results in right ventricle dysfunction. Cardiac magnetic resonance derived RV ejection fraction is a prognostic value in this condition. Right ventricular geometry, function, morphology as well as pulmonary arterial stiffness and size may be evaluated by cardiac magnetic resonance imaging and could have great importance in evaluation of pulmonary hypertension prognosis and outcomes.
Primary objective • To evaluate the effect of rapid inhalation of 2.5μgiloprost using the Breelib nebulizer on pulmonary vascular resistance (PVR) in patients with pulmonary arterial hypertension Secondary objectives - To evaluate the effect of rapid iloprost inhalation using the Breelib nebulizer on mean pulmonary arterial pressure (mPAP), cardiac output (CO), cardiac index (CI), systemic blood pressure, arterial oxygen saturation, heart rate, and pulmonary arterial wedge pressure (PAWP). - To evaluate the safety and tolerability of the rapid iloprost inhalation using the Breelib nebulizer.
Chronic pulmonary hypertension (PH) is associated with impaired exercise capacity, quality of life and right ventricular function. The disease is characterized by an increase of pulmonary vascular resistance and pulmonary arterial pressure, leading to right heart insufficiency. Despite optimized combination-medical therapy most patients remain symptomatic, have reduced exercise capacity, quality of life and reduced survival rates, with an annual mortality rate of approximately 5 -15 % or even higher. Previous training studies have suggested that exercise training as add-on to medical treatment is highly effective improving exercise capacity, quality of life and symptoms. The current guidelines recommend exercise training only in specialized centres including both PH and rehabilitation specialists who are experienced in exercise training of severely compromised patients. A specialized PH-training program has been performed in Heidelberg since 2003 including >1200 patients with various forms of chronic PH. The exercise training program is performed in a special setting with an in-hospital start of the rehabilitation program. It is characterized by a low-dose closely supervised exercise training in small groups with additional psychological support and mental training. This training program for patients with PH will be implemented in European centers to add exercise training to the existing PH therapies. The effect of the training on physical exercise capacity will be assessed by 6-minute walking distance (6-MWD). Further clinical parameters will be assessed to evaluate the effect on exercise capacity, quality of life and symptoms. The aim of this study is to guide European PH-centers to become specialized centers for training in PH. 126 patients will be included, who either receive exercise training or continue their daily sedentary life style (1:1 randomization) for 15 weeks. As inpatient settings are not available in all healthcare systems the training program will be adapted from the specific training program for PH patients developed in Heidelberg to a procedure, which is feasible in the local participating centres. Another objective of this study is to assess if the particular adopted training program specified for each participating centre and country is still safe and effective.
This study aims to evaluate cardiopulmonary interactions in patients with heat failure
The purpose of this prospective research registry is to collect data on treatment strategies and outcomes for premature newborns with severe pulmonary hypertension (PH).
High mortality rates due to cardiovascular disease in end-stage renal disease patients been described by epidemiological and clinical studies. It accounts for approximately 50 percent of deaths in dialysis patients. Although controversial, this may be due to the presence of excess vascular calcification particularly in the form of extensive coronary artery calcification which can be observed even in very young dialysis patients. It was suggested that abnormalities of the right ventricular function in patients with end-stage renal disease were largely due to pulmonary hypertension which usually develops secondary to pulmonary artery calcifications.
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 purpose of the present pilot study is to test the hypothesis that in patients with group 1 pulmonary arterial hypertension (PAH) who are on regular oral pulmonary vasodilator therapy, inhaled albuterol causes transient pulmonary vasodilation.
Pulmonary hypertension (PH) is a serious condition characterized by a mean pulmonary artery pressure >=25mmHg on right heart catheterization (RHC). Despite advances in PH care, outcomes are still sub-optimal and further research is required into the pathobiology of the disease and development of biomarkers that can guide clinical care. The investigators are establishing a biobank to collect samples (blood, urine, stool) from patients with pulmonary hypertension, patients at high risk for pulmonary hypertension, healthy controls, and patients undergoing right heart catheterization. Specimens will be stored for future investigations.
A randomized, double-blind, placebo-controlled dose escalation and verification study to assess the safety and efficacy of pulsed inhaled nitric oxide (iNO) in subjects at risk for pulmonary hypertension associated with pulmonary fibrosis on long term oxygen therapy (Part 1 and Part 2) - REBUILD
