Quantifying 18kDa TSPO Expression in the Lung in Pulmonary Artery Hypertension (PAH)
The aim of this study is to determine whether there is an increase in the TSPO PET signal (measured with the radioligand [11C]PBR28) in the lungs of patients living with PAH relative to age matched controls. If so, TSPO PET may be a useful technique to non-invasively monitor response to …
Non-Invasive Measurements of Changes in Pulmonary Artery Pressure in Intensive Care Unit Patients Using Electrical Impedance Tomography - A Feasibility Study
To assess whether changes in electrical impedance - measured using an electrical impedance tomography (EIT) chest belt - can be used to derive changes in pulmonary artery pressure (PAP) in critically ill patients when compared to invasive gold-standard PAP measured using pulmonary artery catheter (PAC).
Natural History Study of Biomarkers in Pulmonary Arterial Hypertension
Background High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a rare disorder. Some people have disease-associated PAH and some have PAH from an unknown cause. Researchers want to follow the natural history of all PAH patients to understand how PAH progresses in order to discover …
Risk and Resilience in Pulmonary Arterial Hypertension and Genetically Susceptible Individuals
Pulmonary arterial hypertension (PAH) is a severe disease with a delayed diagnosis and markedly elevated mortality. High-risk populations, such as those with known genetic defects, provide a unique opportunity to determine the features of susceptibility and resilience to PAH. This proposal will fundamentally overturn the prevailing understanding of PAH by …
REgistry of Pulmonary Arterial Hypertension Associated With CONNECTIVE Tissue Diseases (RECONNECTIVE)
The RECONNECTIVE Registry is an observational single center study, focused on the subgroup of precapillary pulmonary hypertension related to connective tissue diseases. All patients will have hemodynamic confirmation by right heart catheterization and will be follow-up for at least 5 years from admission. All patients diagnosed with Group I Pulmonary …
The Impact of ERA Switching on Risk Stratification in Pulmonary Arterial Hypertension
Pulmonary arterial hypertension (PAH) is a rare, progressive, and potentially fatal disease characterized by increased pulmonary vascular resistance and right ventricular dysfunction. Among the four major molecular pathways involved in PAH pathophysiology-nitric oxide, prostacyclin, activin, and endothelin-1 (ET-1)-the endothelin pathway plays a central role. Endothelin-1 acts on ETA and ETB …
Exercise Capacity Muscle Oxygenation and Arterial Stiffness in Children With Pulmonary Arterial Hypertension
The primary aim is to evaluate pulmonary function, respiratory muscle strength, upper and lower extremity exercise capacity, muscle oxygenation, dyspnea, peripheral muscle strength, arterial stiffness, physical activity level and balance in children with pulmonary arterial hypertension and compare with age- and sex-matched healthy controls. The second aim is to investigate …
Study Roles of Heavy Metals and Essential Metal Dyshomeostasis in Pulmonary Arterial Hypertension Patients
Investigators plan to recruit 50 PAH patients from UofL PAH Clinic, with various degrees of severity (25 intermediate risk patients and 20 high risk patients) and 10 age and gender matched controls. PAH patients are evaluated at least every 6 months by the PAH Clinic and blood/urine samples will be …
Cardiac Assessment by PV Loop in IPAH and Scleroderma PAH
This observational study is being done to understand why people with scleroderma can develop pulmonary arterial hypertension (high blood pressure in the lungs, abbreviated PAH) and a weak heart muscle (heart failure). The study will also help the investigators understand why people with PAH from an unknown cause (called idiopathic …
Multi-marker Approach for Risk Assessment in PAH
Prospective registry including incident patients and prevalent patients which pretends to identify clinical characteristics, treatment trends in-hospital and ten years follow-up outcome through major adverse cardiovascular events (MACE) in a China population with well characterized PAH.
