Nanjing, JiangsuAges 60–75 - 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+ - NCT06518317RecruitingPhase 3

This trial compares a short course versus a longer course of antiplatelet medicine (blood thinners) after a TAVI procedure for aortic stenosis. It aims to see which approach is safer and more effective.
CaenAges 18 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 - NCT04695106RecruitingPhase 4
Blood Thinner and Heart Attack Prevention Study
This study tests whether taking dabigatran (a blood thinner) combined with ticagrelor (a blood clot preventer) is safe and effective for patients with irregular heart rhythm (atrial fibrillation) who recently had a heart attack and received a stent. The goal is to prevent future blood clots while minimizing bleeding risks.
Gdansk, Pomeranian VoivodeshipAges 18 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 - NCT06414499RecruitingPhase 3
Tenecteplase for mild stroke within 4.5 hours
This trial tests a clot-busting drug called tenecteplase for patients having a mild stroke (with weakness on one side or trouble speaking) who can get treatment within 4.5 hours. The goal is to see if this drug helps improve blood flow and reduces disability.
Beijing, Beijing MunicipalityAges 18 years+ - 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+ - NCT06090890RecruitingPhase 4
Anti-inflammatory therapy for repeated stent blockages
This trial tests if anti-inflammatory drugs like prednisone or colchicine can prevent stents from blocking again in people who have already had multiple stent blockages. It may offer a new treatment option for those with recurrent in-stent restenosis.
Beijing, Beijing MunicipalityAges 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 - NCT06100510Enrolling by invitationPhase 4
Platelet function test in healthy adults
This trial is collecting blood from healthy adults to establish a new reference range for a standard platelet function test. You may be eligible if you do not have any bleeding disorders, are not taking blood thinners or anti-inflammatory medications, and meet other lab criteria.
East Syracuse, New YorkAges 18 years+ - NCT05997693RecruitingPhase 3
One month of blood thinners after heart bypass surgery
This trial tests whether taking just one month of two blood thinners after coronary artery bypass graft (CABG) surgery is safe and as effective as the standard longer course. It focuses on people having their first bypass surgery who receive at least one vein graft from the leg.
Englewood, New JerseyAges 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 - 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+ - 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+ - 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+ - 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 - 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+ - 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+ - NCT05418556RecruitingPhase 4
Comparing antiplatelet strategies after heart stent
