SeoulAges 19–50 - NCT05353140Recruiting
Left atrial appendage device vs blood thinners after stent
This trial compares a heart device that can help prevent blood clots in the heart (called LAAO) versus long-term blood thinners for people who have atrial fibrillation and recently had a stent placed. It aims to see which approach better prevents stroke and related blood-clot problems while keeping side effects manageable.
Xi'an, ShannxiAges 18 years+ - NCT05418556RecruitingPhase 4
Personalized vs standard blood thinner after stent placement
This Phase 4 study compares two anti-platelet (“blood thinner”) plans after you get a drug-eluting stent, using detailed imaging results from the procedure to tailor treatment. It aims to see whether the personalized plan can improve outcomes while keeping bleeding risk safe.
Bucheon-siAges 19 years+ - NCT05476991RecruitingPhase 3
Low-dose colchicine plus ticagrelor to prevent repeat stroke
This Phase 3 study tests whether low-dose colchicine added to ticagrelor (a blood-thinning medicine) helps prevent another ischemic stroke in people whose first stroke was caused by clogged arteries. It aims to lower the risk of repeat stroke after recovery from a recent event.
Paris, ParisAges 18 years+ - NCT05577988RecruitingPhase 3
Genetic-guided weaker blood thinner vs stronger standard therapy
This study tests whether switching early to a weaker anti-platelet medicine based on your genetics can reduce bleeding problems in people at high risk for bleeding after a heart attack. It compares this approach to the usual strategy of staying on a stronger anti-platelet medicine.
Paris, IDFAges 18 years+ - NCT05643651RecruitingPhase 4
Rivaroxaban for kids with large heart artery aneurysms after Kawasaki disease
This trial studies whether rivaroxaban (a blood thinner) can help prevent dangerous clots in children age 2 and older who have “giant” coronary artery aneurysms after Kawasaki disease. Doctors will see if it’s safe and tolerable for children who are also on standard anti-clot/anti-platelet medications for the next 3 months.
Shanghai, Shanghai MunicipalityAges 2–18 - NCT05653973RecruitingEarly Phase 1
Testing aspirin’s effects on blood vessel function after pregnancy
This early study looks at how taking aspirin (or not) affects how well blood vessels work after pregnancy. It may help researchers understand differences in vascular health after normal pregnancies versus preeclampsia (a pregnancy blood pressure complication).
Iowa City, IowaAges 18–50 - NCT05681702RecruitingPhase 4
Personalizing medicines to reduce bleeding after stent procedure
This trial studies ways to reduce bleeding in people after a stent procedure (PCI) who have been taking two anti-platelet medicines (aspirin plus prasugrel or ticagrelor) for a set amount of time. It may help find a safer plan for preventing blood clots while lowering bleeding risk.
Jacksonville, FloridaAges 18 years+ - NCT05709626RecruitingPhase 4
Testing prasugrel alone after stent placement for heart attack
This study checks whether taking prasugrel by itself, after you get a drug-eluting stent for a heart attack (STEMI), can work as well as the standard approach. It may help prevent blood clots in the stent, but it requires specific blood-thinner plans for 12 months.
Sayama, OsakaAges 18 years+ - NCT05955365RecruitingPhase 4
Single anticoagulant blood thinner after stent in atrial fibrillation
This trial tests whether taking a single “P2Y12 inhibitor” blood thinner (instead of multiple medicines) is safe and effective after you get a coronary stent. It’s for people with atrial fibrillation who need long-term blood thinning and have recently had a successful stent procedure.
HasseltAges 18 years+ - NCT05960721Recruiting
Low-dose blood thinner versus standard care after heart appendage closure
This study looks at whether a lower-dose blood thinner works as well as the usual recommended anti-clot treatment after a procedure that closes off the heart’s left atrial appendage. It may help reduce bleeding risk while still preventing dangerous blood clots.
Xi'an, ShannxiAges 18 years+ - NCT05986968Recruiting
Testing ticagrelor alone after a heart attack and stent
This trial tests whether a single blood thinner (ticagrelor) is safe and helps reduce bleeding in the heart muscle in people who have had a specific type of heart attack (STEMI) and a stent. It may be an option if you want to avoid taking aspirin with ticagrelor.
AlkmaarAges 18 years+ - NCT06082063RecruitingPhase 3
Reducing heart disease risk in type 1 diabetes
This trial tests a combination of treatments to lower the risk of heart disease and kidney problems in people with type 1 diabetes who already have some complications or higher risk. If you qualify, you will receive extra care aimed at preventing heart attacks, strokes, and kidney failure.
CopenhagenAges 40–90 - NCT06276374Recruiting
Dual antiplatelet therapy after carotid artery stenting for high bleeding risk
This trial tests if taking two blood thinners (dual antiplatelet therapy) after a carotid artery stenting procedure is safe and effective for patients who have a higher risk of bleeding. It focuses on people with significant blockages in the neck arteries who are also at increased risk for serious bleeding or brain bleeds.
SeoulAges 19 years+ - NCT06478537RecruitingPhase 2
Hetrombopag for Immune Tolerance in ITP After Platelet Recovery
This study tests whether a drug called hetrombopag can help your immune system stop attacking your platelets, so your platelet count stays up even after stopping the drug. It's for people with ITP who responded well to hetrombopag but want to see if they can stay in remission without it.
Beijing, Beijing MunicipalityAges 18–50 - NCT06486792RecruitingPhase 4
Stroke prevention in patients with hidden atrial fibrillation
This trial tests if starting blood thinners can prevent another stroke in people who had a stroke but were found to have a hidden heart rhythm problem called atrial fibrillation. It is for older adults who have had a recent stroke without a known cause.
Paris, ParisAges 65 years+ - NCT06509893RecruitingPhase 4
Ticagrelor alone after stent placement
This study tests if a single blood thinner (ticagrelor) works well enough after getting a heart stent, instead of the usual two blood thinners. It may simplify your daily medication routine.
Shiraz, FarsAges 20–80 - NCT06535568Recruiting
Comparing one vs two blood thinners after heart artery balloon treatment
This trial tests whether taking just one blood thinner (clopidogrel) is as safe and effective as taking two (clopidogrel plus aspirin) for older adults or people at high bleeding risk who have had a drug-coated balloon procedure to open blocked heart arteries.
Milan, MIAges Any age - NCT06548971RecruitingPhase 3
Early antiplatelet after clot-busting for stroke (TREND-IVT)
This trial tests whether giving an antiplatelet medicine (like aspirin) early—within 3 hours of a clot-busting drug—can help prevent another stroke without causing bleeding. It is for people who still have moderate to severe stroke symptoms after the clot-buster and do not have a large artery blockage.
Bengbu, AnhuiAges 18 years+ - NCT06588231Recruiting
