Acute cor pulmonale

This study tests a special pacemaker setting called SyncAV, used with left bundle branch area pacing, in people with heart failure and a heart block. The goal is to see if this setting can improve the heart's electrical timing and pumping strength. About 50 adults who already nee…

This study is testing a small device called the MiniLung petite kit, which helps oxygenate blood and remove carbon dioxide in newborns and children weighing 2 to 8 kilograms who have severe breathing or heart failure. The device works with a console to temporarily take over the w…

This study tests a home-based cardiac rehabilitation program delivered through a custom mobile app for people with heart failure. Participants use the app for education, mindfulness, and physical activity guidance, plus periodic video calls with an exercise physiologist. The goal…

This study follows 400 adults diagnosed with pulmonary embolism (a blood clot in the lungs) at a Swedish hospital. Researchers will repeatedly check heart tests and blood markers during the first 48 hours to see if early changes can better predict who will worsen. The goal is to …

This study looks at whether two proteins released by a struggling heart can be detected in the blood during acute heart failure. Researchers will measure these proteins in about 500 adults—some with stable or worsening heart failure and some healthy—to see if higher levels relate…

Researchers at the University of Calgary are testing a new, non-invasive way to assess heart function using a handgrip exercise. The study involves 100 adults, half with heart failure and half without. Participants squeeze a device with maximum force for two minutes while sensors…

This study follows 100 adults who needed ECMO support for severe heart or lung failure. Researchers will track muscle size, strength, and quality of life over time to understand why some patients develop lasting weakness. No new treatments are being tested; the goal is to gather …
