PULMONARY EMBOLISM

This study compared two blood thinners, rivaroxaban (Xarelto) and apixaban (Eliquis), in 2760 adults with new blood clots in the legs or lungs. The goal was to see which drug causes fewer bleeding problems. Results could help doctors choose the safer option for treating venous th…

This study investigates whether delivering a clot-dissolving drug directly into the lung arteries via a thin tube (catheter) can improve outcomes for people with a serious type of pulmonary embolism (a blood clot in the lung). Participants have intermediate-high risk clots, meani…

This study tested a new device called the Vertex Pulmonary Embolectomy System in 10 people with pulmonary embolism (blood clots in the lungs). The device is threaded through a blood vessel to remove clots and relieve strain on the right side of the heart. Researchers measured cha…

This study tested a new device called the Hēlo PE Thrombectomy System, which is a thin tube used to remove blood clots from the lungs in people with a serious condition called pulmonary embolism. The trial included 177 participants and aimed to see if the device is safe and works…

This study tested a special filter placed in a large vein to catch blood clots before they reach the lungs. It included 50 people who could not take blood thinners. The goal was to see how often the filter could be successfully placed and removed, and to track any problems.

This study tested a device that removes blood clots from the main lung arteries in 123 people with a sudden pulmonary embolism. The goal was to reduce strain on the right side of the heart and prevent serious complications like major bleeding or heart injury. Participants were ad…

This study looked at whether a low dose of the blood thinner apixaban (2.5 mg twice daily for 12 months) can safely prevent blood clots from returning in people who already had a clot triggered by a temporary risk factor. 600 high-risk adults took either apixaban or a placebo. Th…

This study tested a device called FlowTriever that mechanically removes blood clots from the lungs, comparing it to standard clot-dissolving drugs (catheter-directed thrombolysis). 692 patients with acute pulmonary embolism were enrolled. The goal was to see which treatment leads…

This study tested a device called the FlowTriever2 Catheter in 50 people with acute pulmonary embolism (blood clots in the lungs). The device was used to mechanically remove clots from the lung arteries. Researchers measured safety by tracking serious side effects and effectivene…

This study looked at whether an ultrasound of the leg veins can help doctors diagnose a repeat pulmonary embolism (a blood clot in the lung). About 115 adults with symptoms of a new clot were checked. The goal was to see if adding leg ultrasound to the usual tests (like blood wor…

This study tested how well a small, portable device (LumiraDx) measures blood clotting (INR) compared to standard lab tests. Researchers collected blood from 420 adults, some taking warfarin and some not, using both a fingerstick and a vein draw. The goal was to see if the device…

This study tested a new rapid D-dimer blood test (LumiraDx) in 679 people with symptoms of deep vein thrombosis or pulmonary embolism. The test uses a small blood sample from a finger prick or vein to quickly measure D-dimer levels, which can help rule out dangerous blood clots. …

This study tested a new way to decide if someone with a suspected blood clot in the lung needs a scan. The 4PEPS score uses 12 simple factors and a blood test to classify risk into four levels. Over 3,000 patients in 20 emergency departments took part. The goal was to see if usin…

This study tested whether a simple checklist and blood test (the YEARS algorithm) can safely rule out pulmonary embolism (a blood clot in the lungs) in people with active cancer, compared to the standard approach of doing a CT scan on everyone. About 700 cancer patients with susp…

This study tested a new CT scan method that creates a map of blood flow in the lungs to diagnose pulmonary embolism (blood clots). Researchers compared it to the standard SPECT scan in 30 patients. The goal was to see if the new method is as accurate, while being faster and safer…

This study tested whether a special PET/CT scan (V/Q PET/CT) can accurately diagnose pulmonary embolism (a blood clot in the lungs) compared to the standard CT scan. About 100 adults with suspected first-time clots took part. The goal was to see how sensitive and specific the new…

This study compared three common blood thinners—aspirin, warfarin, and rivaroxaban—to prevent dangerous blood clots after hip or knee replacement surgery. Nearly 19,000 adults took part. The goal was to find which option best balances preventing clots with avoiding bleeding side …

This study looked at whether having COVID-19 makes people more likely to develop a pulmonary embolism (a blood clot in the lungs). Researchers reviewed medical records of 347 patients who had a CT scan of their lungs. They compared those who tested positive for COVID-19 with thos…

This study looked at whether sending alerts to pharmacists instead of doctors helps improve how blood thinners (anticoagulants) are prescribed. Researchers tested two types of alerts with 306 healthcare providers. The goal was to see which method leads to faster and safer prescri…

This completed study tested whether semaglutide, a drug used for diabetes, could reduce inflammation in 18 people who had a blood clot in their lungs (pulmonary embolism). Researchers measured changes in blood markers of inflammation over 4 weeks. The goal was to see if the drug …

This study looked at how well hospitals follow the standard protocol for giving heparin, a blood thinner, to patients with blood clots or heart issues. Researchers checked 100 patients to see if their heparin doses were adjusted correctly based on blood test results. The goal was…

This study looked at 40 adults who had a blood clot in their lungs (pulmonary embolism). Researchers compared those who also had sleep-disordered breathing (like sleep apnea) with those who did not. The goal was to see if sleep problems affect short-term recovery and the chance o…

This study tracked 88 adults diagnosed with pulmonary embolism (a serious blood clot in the lungs) during April 2020, the peak of the COVID-19 pandemic in France. Researchers compared complications like recurrence of clots, lung scarring, and death over 6 to 12 months between pat…

This study looked at 10 people hospitalized with a blood clot in the lung (pulmonary embolism). Researchers used a special 3D CT scan technique to compare lung blood vessels before and 48 hours after standard blood thinner treatment. The goal was to measure changes in blood flow …

This study measured certain proteins (histones and HMGB1) in the blood of 115 pregnant women to see if they could help detect placenta-related complications like pre-eclampsia. Researchers compared women with normal pregnancies, those with complications, and healthy non-pregnant …

This study measured the amount of free-floating DNA and nucleosomes in the blood of 137 women to see if these levels differ between those with pregnancy complications (like preeclampsia or blood clots) and healthy women (both pregnant and non-pregnant). The goal was to better und…

This study tested a step-by-step method called SEARCH to better classify what happens to people long after a pulmonary embolism (a blood clot in the lungs). Researchers looked at 150 adults to see if the method reliably identifies different outcomes, from full recovery to chronic…

This study tested whether a home rehabilitation program, with daily activity tasks and heart rate monitoring sent by text or email, helps people recover better after a serious blood clot in the lung (pulmonary embolism). 32 adults who had been hospitalized for this condition took…

This completed study looked at 11,000 COVID-19 patients to understand how often they develop dangerous blood clots in arteries or veins. Researchers tracked clot rates, risk factors, and outcomes over 30 and 90 days. The goal was to learn more about these complications to improve…

This study looked at 744 people who had a blood clot before and were suspected of having another one. Researchers tested three different checklists (called clinical decision rules) to see how well they could tell if a new clot was really there. The goal was to help doctors avoid …
