Los Angeles, CaliforniaAges 55 years+ - NCT04263038RecruitingPhase 4
Watchful waiting versus blood thinners for small lung clots
This trial compares close monitoring (“watch and wait”) versus taking the blood thinner rivaroxaban in people with a small type of lung blood clot. It aims to find out whether low-risk patients can safely avoid or reduce anticoagulation while still staying healthy.
Woluwe-Saint-Lambert, Brussels CapitalAges 18 years+ - NCT04284839RecruitingPhase 3
Blood thinner pills vs warfarin after heart surgery
This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.
Fitzroy, VictoriaAges 18 years+ - NCT04262492Recruiting
Registry of adults with APS on blood thinners
This study keeps an international registry of people with antiphospholipid syndrome (APS) who are taking direct oral blood thinners. It may help doctors better understand how APS patients do over time and improve future care, even if you’re not asked to change treatment.
NancyAges Any age - NCT04045665RecruitingPhase 3
Blood thinner vs usual care for new heart rhythm after bypass surgery
This trial tests whether using a blood thinner in people with new, temporary atrial fibrillation after CABG (heart bypass surgery) can reduce harmful outcomes compared with standard treatment. It may help prevent stroke or other complications if your rhythm problem fits the trial’s timing and risk profile.
Little Rock, ArkansasAges 18 years+ - NCT03297281Recruiting
Stopping or continuing blood thinners during prostate vaporization
This study compares whether people can safely stop or continue oral blood thinners during a prostate procedure called photovaporization. It may help reduce bleeding risk without increasing dangerous clot risks for the right patients.
ToulouseAges 18 years+ - NCT05283174Recruiting
Blood thinner use during stroke to predict outcomes
This study looks at how people doing well on certain blood thinners do when they have a stroke or bleeding while taking them. It will measure medication levels in your blood to understand stroke severity and recovery in the short and long term.
TaipeiAges 20 years+ - NCT05378308Recruiting
Tracking blood thinner use in people with AF or blood clots
This registry study looks at how people with atrial fibrillation (AF) or blood clots (VTE) use blood thinners, especially NOACs, over time. It may help doctors better understand real-world patterns of treatment and outcomes.
Zhengzhou, HenanAges Any age - NCT03302195Recruiting
Heparin and bypass blood management for obese heart surgery
This trial studies the best way to manage blood thinning (anticoagulation) during heart surgery that uses a heart-lung machine in people with obesity. It may help reduce blood-clotting and bleeding complications by comparing different care strategies.
Québec, QuebecAges 18 years+ - NCT04814212Recruiting
Testing a drug-coated balloon for people with bleeding risk
This trial looks at whether a “drug-coated balloon” used during a heart procedure (PCI) is safer or better for people who are at higher risk of bleeding while on blood thinners. It may help reduce complications around the time of the procedure in people like you.
Jyväskylä, Central FinlandAges 18 years+ - NCT03642509Recruiting
Compare a heart procedure to blood-thinner pills for stroke prevention
This trial studies whether closing off part of the heart (the left atrial appendage) can prevent stroke as well as long-term newer blood-thinner pills. It may help people with atrial fibrillation who recently had a stroke or a warning stroke (TIA).
Aarhus, Central JutlandAges 18 years+ - NCT06187311RecruitingPhase 4
Rivaroxaban for atrial fibrillation patients
This trial tests two doses of rivaroxaban (15mg and 20mg) to see how well they prevent strokes in people with non-valvular atrial fibrillation, a type of irregular heartbeat not caused by a heart valve problem. It may be an option if you need blood thinners to lower your stroke risk.
SeoulAges 19–99 - NCT06362343Recruiting
Personalized dosing study for Xa inhibitor blood thinners
This study looks at how the body processes a certain type of blood thinner (Xa factor inhibitors) to help doctors find the right dose for each person. If you have a blood clot in your lungs and are on long-term treatment, this trial might help improve your care.
Beijing, Beijing MunicipalityAges 18–120 - NCT06021808Recruiting
LAA clip vs. blood thinners to prevent stroke in non-paroxysmal AF
This study compares two ways to prevent stroke in people with persistent or long-standing atrial fibrillation (AF): taking a blood thinner (NOAC) or having a minimally invasive procedure to clip off the left atrial appendage (LAA). The goal is to see which approach works better at preventing stroke without causing major bleeding.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04847752Recruiting
Predicting outcomes after stroke from artery plaque
This study looks at factors that can help predict recovery and risk after an ischemic stroke caused by plaque buildup in a major artery. It may help doctors better forecast prognosis and tailor follow-up care for people like you.
WuhanAges Up to 80 years - NCT06487052Recruiting
Catheter-based clot-dissolving drug for intermediate-high risk pulmonary embolism
This trial tests whether a standard procedure using a catheter to deliver clot-dissolving medicine directly into the lung artery works well for people with a serious but not immediately life-threatening blood clot in the lungs (pulmonary embolism). It aims to improve heart function and reduce long-term complications.
Saint PetersburgAges 18 years+ - NCT07801638Recruiting
Anticoagulation plus tocilizumab for cerebral venous thrombosis
This trial tests a combination of blood thinners (anticoagulation) and a drug called tocilizumab, which targets inflammation, to treat acute cerebral venous thrombosis (a blood clot in a vein in the brain). It aims to see if this combined treatment improves recovery and reduces complications compared to blood thinners alone.
Beijing, Beijing MunicipalityAges 18–80 - NCT04257487RecruitingPhase 3
Sulodexide to prevent blood clots from coming back
This study tests sulodexide (a blood-vessel protective medicine) to help stop deep leg blood clots or lung clots from returning after you’ve already been treated. It may help people with higher bleeding risk who are taking or recently finished standard anticoagulant medicines.
RozzanoAges 75 years+ - NCT06556446Recruiting
Clot-busting drug after stroke if on blood thinner
This study looks at whether giving a clot-busting medicine (IV thrombolysis) is safe and effective for people who have had a stroke and also recently took a direct oral anticoagulant (DOAC). If you've taken a DOAC in the last 48 hours, this trial may help doctors decide the best treatment for you.
InnsbruckAges 18 years+ - NCT06108414RecruitingPhase 4
