A Study of Oral Nitrate in Adults With Pulmonary Hypertension With Heart Failure and Preserved Ejection Fraction

This is an open-label, single-center study to examine distinguishing features of the structure and function of the oral and gut microbiome in healthy adult normal volunteers compared to volunteers with PH-HFpEF in the breakdown of oral nitrate.

Outpatient Vasodilator Assessment Using Iloprost in Pulmonary Hypertension

This study will compare the clinical efficacy of inhaled iloprost as an invasive, selective vasodilator in the cardiac catheterization laboratory in patients with pulmonary hypertension to the gold standard of inhaled nitric oxide. It will also examine whether echocardiographic estimates of response to inhaled iloprost can predict responsiveness to invasive …

Catheter Ablation of Atrial Fibrillation in Patients With Pulmonary Hypertension Hypertension: a Randomised Study

Atrial fibrillation (AF) and atrial tachycardia (AT), including type I atrial flutter, are frequently observed in patients with pulmonary hypertension (PH). Catheter ablation of AF / AT has been established as an effective treatment option in selected patients. However, little is known about the efficacy and safety of this approach …

Inhaled Nitric Oxide for Pulmonary Hypertension and Bronchopulmonary Dysplasia

Inhaled nitric oxide (iNO) is an effective treatment for pulmonary hypertension (PH) in term and near-term infants. Preterm infants are at risk for early PH that is associated with high risk for bronchopulmonary dysplasia or death. In multiple clinical trials, iNO treatment was not effective for BPD prevention. However, infants …

Pedometers and Walking Tests for Pulmonary Hypertension Patients

Concordance between walking tests and pedometer data may seem like a logical outcome for pulmonary hypertension (PH) patients. However, many individuals have discordant results: results much worse or better during an in-hospital walking test as compared to real life activity. The primary objective of this study is: to determine variables …
