Filter by:Heart Failure with Preserved Ejection Fraction (HFpEF) and Pulmonary Hypertension (PH) can be diagnosed noninvasively by Exercise Echocardiography (ExE) and Cardiopulmonary Exercise Testing (CPX) as compared with gold standard invasive hemodynamic assessment.
This is a four-part study of the safety, tolerability, and PK profile of sodium nitrite inhalation solution (AIR001) of ascending multiple doses (Part A) and of escalating doses with steady-state sildenafil (Part B) to healthy male and female subjects, as well as assessment of the safety and tolerability of multiple doses of AIR001 to patients with pulmonary arterial hypertension (part C) with a single dose PK study of AIR001 utilizing three different nebulizers (Part D).
The 6 minute walk (6MW) gives information about the exercise capacity and it is an important tool for clinical decisions and for the prognostic evaluation of PH patients. The test is technically simple to perform, inexpensive and reproducible. During the 6MW O2 saturation, heart rate, walking distance (in this study after every minute) and the level of dyspnea (BORG-dyspnea scale) may be recorded; however, at present, mainly the walking distance is evaluated. The test is sometimes criticized, because of the dependence on the patient's motivation. The purpose of the present study is to standardize the test by the incorporation of objective factors. The investigators are correlating the change of heart rate and dyspnea (BORG scale) with the achieved walking distance during subsequent examinations performed with different effort.
Aim of this study is to investigate whether and to what extent a cautious respiratory and exercise therapy can complement medical treatment and change the condition, oxygen uptake, quality of life, the pulmonary vascular pressures, the size of the right heart and the 6-minute walk distance in patients with pulmonary hypertension.
The investigators hypothesise that pre-application of Qutenza® patches to the skin may reduce pain at the site of Remodulin® SC infusion (sited 1 to 2 weeks later at the site of Qutenza pre-application), in which case it would greatly improve the quality of life of the patients, and enable many more to continue with this treatment. It may also provide new information to support the use of Qutenza® patches for preventing and reducing pain produced by inflammation. The present study will explore the efficacy of single applications of Qutenza® (capsaicin 8% patch) in reducing site pain caused by continuous SC infusion of Remodulin®, in pulmonary arterial hypertension patients, as assessed by changes in subjective pain rating score and/or pain and sensory testing.
This is an open-label, uncontrolled, prospective long-term observation of Specific Drug in the treatment of patients with pulmonary hypertension up to 4 years. 160 patients with primary (idiopathic and familial) pulmonary hypertension (PH) or pulmonary arterial hypertension (PAH) due to scleroderma with New York Heart Association (NYHA) functional class and exercise capacity, defined as class III and IV planned to enroll. Efficacy, safety and tolerability of the drug and the survival of the patients will be observed.
The investigators aim to : - describe and analyse psychological characteristics, cognitive factors and representations in patients with Pulmonary Hypertension, a rare disease. - assess the psychological characteristics impact on quality of life, check the association between disease and QoL evolution, and the variability of QoL parameters over severity class changes and follow-up
Pulmonary hypertension (PH) is a serious complication of COPD which is associated with shorter survival, more frequent exacerbation, and increased use of health resources. There is no effective pharmacological treatment for COPD-associated PH. Therefore, the investigators wanted to evaluate the effect of udenafil, a phosphodiesterase- 5 (PDE-5) inhibitor, on exercise capacity of severe COPD patients.
Endothelin receptors antagonists (ERA), such as bosentan and ambrisentan, are a class of vasoactive drugs that have been developed for the treatment of pulmonary arterial hypertension. It has been anecdotally reported that ERA is frequently used among top-level athletes to counteract exercise-induced rise in pulmonary vascular pressures and increase exercise performance. Yet, the effects of ERA on exercise capacity in healthy humans are puzzling, with the drugs not included in the current Prohibited List, since the ergogenic potential is yet to be fully understood and determined. Furthermore, the urinary excretion of ERA metabolites following administration has not been studied systematically at rest and during exercise in athletes, as a way to detect its intake if performance-enhancing potential is confirmed. In the planned study ERA will be administered in newly approved doses for 8 weeks in order to assess the presumed doping potential for both male and female athletes, and to monitor serum and urinary ERA excretion dynamics after single- and multiple-dose administration. The possible effects of prolonged ERA administration in higher doses on exercise performance may be relevant, if further confirmed, in terms of their possible fraudulent utilization to influence exercise performance in sports, raising the difficult question of whether, particularly in some circumstances, the ERA might be considered as prohibited substances in athletes.
This study is designed to assess the efficacy and safety of tadalafil in patients with Sarcoidosis Associated Pulmonary Hypertension. Hypothesis: Tadalafil is safe and effective in treating pulmonary hypertension in patients with Sarcoidosis
