Pulmonary embolism acute

This study tests a new device called the Vibrato Aspiration System, designed to remove blood clots from the lungs in people with acute pulmonary embolism (a sudden blockage in the lung artery). The trial includes up to 10 adults aged 18 to 75 who have had symptoms for 14 days or …

This study tests a device that removes blood clots from the lungs of people with acute pulmonary embolism and then returns the cleaned blood back to their body. The goal is to see if this approach is safe and effective at reducing blood loss and complications. About 39 adults wit…

This study explores whether a low-dose CT scan without contrast dye can accurately detect pulmonary embolism (blood clots in the lungs). Researchers will enroll 750 adults suspected of having a clot and add two very low-radiation CT scans to their standard dye-based scan. The goa…

This study is testing whether a noninvasive imaging technique called pulsatile electrical impedance tomography (EIT) can accurately diagnose acute pulmonary embolism — a life-threatening blood clot in the lungs. Researchers will compare EIT readings with standard CT scans in 275 …

This study tests whether giving the flu vaccine to heart patients just before they leave the hospital can lower their risk of infections, heart problems, and death in the next 6 months. About 400 adults hospitalized for serious heart conditions will be randomly assigned to get th…

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 is observing 500 adults with severe pulmonary embolism (a dangerous blood clot in the lungs) to see if the timing of clot-busting treatments affects survival and complications. Researchers want to find the optimal time window to start treatment, similar to how heart at…

This study is testing whether a simple one-minute chair stand test can help doctors predict how well patients will recover from a non-severe pulmonary embolism (a blood clot in the lungs). Researchers will compare the test results with standard risk scores that use blood tests an…
