Pulmonary hypertension often goes undiagnosed for a long time because early symptoms are vague. Researchers at Assiut University Heart Hospital are studying whether a longer delay before diagnosis is linked to more advanced disease when patients first present. The study will revi…

Researchers are testing whether a one-week stay at sea level improves walking ability and blood oxygen in people with pulmonary arterial hypertension who live permanently above 2600 meters. The study compares these patients with healthy controls from the same altitude, measuring …

This trial asks whether a one-week stay at sea level can lower blood pressure in the lungs of people with pulmonary arterial hypertension who live permanently above 2600 meters. Researchers will compare heart and lung measurements taken at high altitude with those taken after sev…

This study looks at what happens when people with pulmonary arterial hypertension, a condition that raises pressure in the lung's blood vessels, travel from their homes above 2600 meters down to sea level for a week, and then return. Researchers will measure heart rate variabilit…

Researchers are studying what happens when people with pulmonary arterial hypertension who live above 2600 meters spend a week at sea level. The trial compares their sleep, blood oxygen, and breathing during sleep at altitude and after seven days at sea level. It includes both pa…

This observational study follows people with obesity-related heart failure to see how their heart performs during exercise, using stress echocardiography. It observes those who are taking GLP-1/GIP receptor agonists (like semaglutide or tirzepatide) as part of their routine care,…

This study tests whether a small implanted sensor, called CardioMEMS, can continuously track blood pressure in the lung arteries after surgery for chronic thromboembolic pulmonary hypertension (CTEPH). The surgery, called pulmonary endarterectomy, can cure CTEPH, but some patient…

This study looks at whether environmental toxins, drugs, and workplace exposures play a role in causing pulmonary arterial hypertension (PAH), a rare and serious lung condition. Researchers will compare 150 newly diagnosed patients with PAH to those with another form of pulmonary…

This study uses ultrasound to examine how the right side of the heart and the lungs' blood vessels work together during severe COPD flare-ups. Researchers will measure changes in heart-lung coupling in 115 patients admitted to intensive care, comparing readings during the acute e…

This study gathers data from 392 adults with heart failure who need a right heart catheterization. Researchers will use the data to train a machine learning model for a non-invasive device that estimates heart pressure. The goal is to help doctors monitor and treat heart failure …

This study looks at why people with end-stage kidney disease on dialysis often develop high blood pressure in the lungs (pulmonary hypertension). Fluid buildup can make this condition seem worse than it is. Researchers will first correct fluid levels, then use heart ultrasound an…
