Filter by:Open-label pilot study of early inhaled nitric oxide (iNO) for patients developing de novo pulmonary hypertension during Acute Respiratory Distress Syndrome (ARDS.) The study aims to determine whether iNO has possible hemodynamic and clinical benefits when given early in the course of ARDS to patients with evidence of elevated pulmonary artery pressure.
Chronic respiratory diseases are a global burden. Treatment options have improved in recent years, pulmonary rehabilitation plays a key role. Oxygen therapy is recommended in patients with a low saturation at rest, but no clear guidance is given for patients who desaturate during exercise. The effect of ambulatory oxygen during exercise is not yet completely understood, especially in those patients with exercise-induced desaturation. Aim: The goal of this study is to analyse the effect of supplemental oxygen given during a constant work rate exercise test (CWRET) on a cycle ergometer compared to sham air. Methods: We plan to include 25 Patients respiratory patients undergoing pulmonary rehabilitation (male and female; aged >18 years; stable condition >3 weeks (e.g. no exacerbations); resting oxygen saturation (SpO2) ≥ 88%) with exercise induced hypoxemia defined by a fall in oxygen saturation by ≥ 4% during a 6-minute walking test. Patients will undergo an incremental exercise test with a ramp protocol (for evaluating the maximal workload) and two CWRET (75% of the maximal workload) with ambulatory oxygen or placebo (sham air) via standard nasal canula at a flow rate of 5l/min. Patients and assessors will be blinded. The difference endurance time of the CWRET with oxygen vs. sham air will be the primary outcome of this study. Data will be summarized by means (SD) and medians (quartiles) for normal and non-normal distributions. Effects of treatment will be evaluated by mean differences with 95% confidence intervals, T-tests or Wilcoxon matched pair tests as appropriate. A p-value threshold of <0.05 or a confidence interval not including zero will be considered as statistically significant. Analyses will be performed according to the intention to treat principle.
To identify Predictors of pulmonary hypertension in COPD patients and its relation to different levels of smoking
The goal of this pilot study is to evaluate the safety and efficacy of pulmonary artery denervation (PADN) in combined post- and pre- capillary pulmonary hypertension (CpcPH) associated with chronic heart failure(CHF). Participants who have received guideline-directed medical therapy (GDMT) according to 2022 AHA/ACC Guidelines for Heart Failure (HF) and have been clinically stable for at least 1 month, will be treated with PADN and followed for 1 year.
Adult patients with suspected or confirmed Connective Tissue Disease Patients (CTD)With Pulmonary Hypertension(PH)will be recruited. Patients will be approached, consented, have baseline demographics, diagnostics and disease activity measures recorded, and blood taken. The collection of data and biological material will mirror usual clinical practice as far as possible. Subjects will ideally attend further visits at 3, 6 and 12 months to have bloods taken, outcome measures recorded and questionnaires completed.
The investigators will study whether the drug tadalafil improves shortness of breath in 126 Veterans with Chronic Obstructive Pulmonary Disease (COPD) and high blood pressure in the lungs. The investigators will also assess whether tadalafil improves quality of life, home daily physical activity, exercise endurance, the frequency of acute flares of COPD, blood pressure in the lungs, and lung function. Veterans who enroll in the trial will be allocated by chance to either active tadalafil or an inactive identical capsule (placebo). Neither the Veteran nor the investigator will know whether the Veteran is taking tadalafil or placebo. Veterans will be followed closely in clinic or by telephone at 1, 2, 3, 4, 5, and 6 months, with attention to side effects and safety. At 1,3, and 6 months the investigators will repeat the questionnaires and testing of blood pressures in the lung and lung function. The investigators anticipate that the results of this study will determine whether tadalafil improves shortness of breath when added to usual medications for COPD.
Taking part in medical trials usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This study will admit a wide range of data on the clinical trial experience of pulmonary hypertension patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future pulmonary hypertension patients.
Pulmonary arterial hypertension (PAH) is a serious, progressive disease that causes pulmonary arterial pressure, significantly affecting functional capacity and quality of life. Over the last few years, knowledge in pulmonary hypertension has evolved consistently and significantly. New diagnostic and treatment algorithms were combined based on the results of several clinical studies that showed the usefulness of new tools, as well as the effectiveness of new drugs as well as non-pharmacological treatment. The new guidelines felt the benefits of physical exercise in individuals with PAH, with promising results in improving symptoms, exercise capacity, peripheral muscle function and quality of life. With the COVID 19 pandemic, the complex scenario was for world health, and social distancing made it impossible to carry out individual outpatient rehabilitation, in groups and in person, indicating the need for rehabilitation programs, including physical training, to be adapted to the domicile. New alternative modes of pulmonary rehabilitation include home-based models and the use of telehealth. Telerehabilitation is the provision of rehabilitation services at a distance, using information and communication technologies. To date, there has been no evaluation of the clinical efficacy or safety of telerehabilitation in the population affected by PAH.
This clinical investigation is a prospective, multicenter, non-randomized, open-label, Early Feasibility Study to evaluate the safety, performance, and initial clinical efficacy of the Rivet PVS therapy in patients with symptomatic pulmonary hypertension.
Extremely preterm infants are at risk for developing bronchopulmonary dysplasia (BPD) and associated chronic pulmonary hypertension (PH), a consequence of altered pulmonary vasculature. This condition occurs in about 25% of babies with BPD, and the association grows with increasing BPD severity. Other risk factors have been described as well. Morbidity and mortality associated with prematurity and/or BPD increase significantly in the presence of PH. Thus, international guidelines encourage the use of standardized screening protocols for this condition. However, several questions regarding these recommendations are left unanswered, such as a clear definition for PH in this population. The research aim is to prospectively evaluate prevalence, risk factors and clinical course of PH in these children. The investigators aim to identify at-risk infants early on and ultimately improve survival making use of an early targeted intervention.
