Idiopathic pulmonary arterial hypertension

This trial tests whether adults with pulmonary arterial hypertension (PAH) can safely switch from selexipag, a pill taken by mouth, to LIQ861, an inhaled form of treprostinil. Participants stop selexipag on day one and start taking LIQ861 four times a day using a handheld inhaler…

This study tests whether quickly starting and increasing guideline-recommended heart failure medications after hospitalization improves outcomes in women. About 360 women from 13 Italian hospitals will be randomly assigned to either a high-intensity care group (rapid drug optimiz…

This study tests a new adjustable cooler for storing donor hearts during transport to the transplant hospital. The cooler aims to keep the heart at a steady temperature, reduce waste, and lower costs compared to the current standard device. About 80 adults receiving a heart trans…

This study tests whether a new risk algorithm (FIND HF) can better detect undiagnosed heart failure in people at risk. About 475 adults aged 40+ will have a blood test and heart ultrasound. Researchers will compare how many high-risk vs low-risk people are found to have heart pro…

This study is creating a large collection of blood samples and medical information from 1000 adults with or suspected of having pulmonary hypertension (PH). Researchers hope this resource will help them find new ways to diagnose and treat PH. Participants will provide a blood sam…

This study will look at 60 adults with a type of high blood pressure in the lungs (pre-capillary pulmonary hypertension) to see if measurements from a CT scan match those from a standard invasive heart catheter test. If the CT scan proves reliable, it could offer a safer, less in…

This study looks at whether different types of exercise (like walking or strength moves) and timing (morning vs. evening) can safely lower blood pressure in people with glaucoma and high blood pressure. About 60 adults will try four exercise sessions, and their blood pressure and…

This study looks at 600 people (400 with chronic heart failure and 200 healthy) to find patterns in genes, proteins, and gut bacteria that may predict who gets worse. Researchers will track patients for one year to see who is hospitalized or dies. The goal is to create a better r…

This study uses a short questionnaire to learn where patients with pulmonary hypertension and their caregivers search for health information, what topics they look for, how satisfied they are, and which sources they trust most. Researchers will enroll 100 adults in Brazil. The go…
