Filter by:The aim of this study is to investigate the underlying inflammatory profile in patients with chronic lung disease and determine the association pulmonary hypertension.
Prospective registry and biobank for long-term observational studies in adult patients with pulmonary hypertension
This comparative diagnostic accuracy study will determine the accuracy of a noninvasive wearable infrasonic sensor to detect the mechanical, electrical, and hemodynamic function of the cardiovascular system.
The purpose of this study is to develop and evaluate the usefulness of hyperpolarized (HP) 129Xe gas MRI for regional assessment of pulmonary function.
This study was conducted in 120 patients aged from 54-65 years scheduled for elective valve replacement surgeries. Patients were randomly allocated to nitro glycerine or PGI2 groups. Patients of nitro glycerine group received nebulized nitro glycerine at a rate of 2.5-5 mcg/kg/min (5 mg, 1 mg/ml) over 10 minutes by ultrasonic nebuliser. Patients of PGI2 group received nebulized PGI2 (epoprostenol), 20000 ng/ml (20000 ng/ml in 60 ml syringe was attached to an intravenous pump which delivers a titrating rate of 8 ml/h . The primary outcome was mean pulmonary artery pressure. The secondary outcomes included mean arterial blood pressure (MAP) (mmHg), PaO2/FiO2 ratio, cardiac index (CI) (l/min/m2) right ventricular ejection fraction (RVEF), central venous pressure(CVP) , 30-day mortality rate and the incidence of complications such as facial flushing, hypotension and re-exploration for bleeding.
Pulmonary arterial hypertension (PAH) is a severe, progressive and potentially fatal disease that impairs the pulmonary circulation and leads to right ventricular failure. One of the world most prevalent etiologies of PAH is schistosomiasis-associated pulmonary arterial hypertension (Sch-PAH). New drugs have emerged to treat other forms of PAH, but their benefits cannot be automatically translated for Sch-PAH patients, since this etiology was not included in the pivotal PAH trials. One of the most promising therapies for the treatment of PAH to emerge in recent years is selexipag, an oral IP receptor agonist, which acts on the prostacyclin pathway. The present study aims to evaluate the efficacy, safety and tolerability of selexipague for the treatment of schistosomiasis-associated pulmonary arterial hypertension.
This prospective study is a multi-center early feasibility study assessing the safety and performance of the Aria CV Pulmonary Hypertension System in patients with pulmonary hypertension and right heart dysfunction.
Arrhythmias are considered a prominent phenomenon in pulmonary hypertension (PH) as the disease progresses. According primarily to retrospective studies with up to 24 hours of monitoring, supraventricular tachycardias (SVT) can be found in 8-35% of patients, with significant impact on survival. Furthermore, a few prospective studies to date deploying short-term monitoring (10 minutes-24 hours) have revealed lower heart rate variability (HRV) in patients with pulmonary arterial hypertension (PAH). In ASPIRE arrhythmias and heart rate variability is being assessed via long term monitoring. Currently the the loop-recorder is considered the gold standard for long-term continuous cardiac montoring. A non-invasive continuous monitoring could be of a great benefit for the patients, and could potentially contribute to treatment optimization. The study will assess apple watches as a non-invasive tool compared to to the loop recorder, which is considered as the current gold standard. Additionally, the study seeks to assess apple watches for monitoring as an independent wearable for risk assessment in PH.
Pediatric idiopathic pulmonary hypertension has significant morbidity and mortality. An ever expanding body of knowledge indicates the important contribution of inflammation to pathogenesis and successful treatment with glucocorticoids. Over the last several years the investigators have utilized steroids in patients with severe pulmonary hypertension as part of a treatment regimen. These basic science studies possibly identifies a biochemical etiology for the development of disease and may also be impacted by the administration of steroids. Additionally, there is a commercially available assay which tests for all of the above molecules.
Pulmonary hypertension (PH) is a disorder of high blood pressure that impacts the heart and lungs. Approximately, 50% of individuals with PH experience anxiety or panic disorders. There is limited evidence on psychological treatments for anxiety in PH; however, results support the use of Cognitive Behavioural Therapy (CBT). Despite the prevalence and impact of anxiety in PH; there are no widely available and/or disease specific pathways, thus highlighting an unmet need in this population. This project aims to develop and pilot, using randomised control trial methodology, a self-management intervention for individuals with PH based on principles of CBT.
