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+ - 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.

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 - 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 - NCT02735707RecruitingPhase 3
Adaptive trial for severe pneumonia care in intensive care
This study tests ways to improve treatment for adults with severe pneumonia that lands them in the ICU, adjusting the plan as results come in. It may help your care team find better treatments for lung infection and breathing/heart support needs.
Jacksonville, FloridaAges 18 years+ - NCT04937699RecruitingPhase 4
Switching anti-platelet tablets after a heart stent
This trial studies whether changing the timing and type of blood-thinner tablets after a heart stent is as safe and effective as continuing the same plan. It may help some people by simplifying treatment while preventing dangerous clotting after a coronary procedure.
Hangzhou, ZhejiangAges 18–80 - NCT07613840Recruiting
Personalized Blood Clot Prevention After Leg Artery Surgery
This study tests a personalized approach to prevent blood clots in patients who have had surgery to repair blocked arteries in their legs. Researchers want to find the best blood-thinning medication for each individual to reduce serious complications while keeping you safe.
Boston, MassachusettsAges 18 years+ - NCT07542860Recruiting
Comparing two aspirin doses in older heart disease patients
This study compares whether a lower dose of aspirin (50 mg) works as well as a standard dose (100 mg) for older adults who have had heart attacks, strokes, or other heart and blood vessel problems. The goal is to find the safest effective dose to prevent future events.
BeijingAges 60 years+ - NCT06588231Recruiting
Personalized exercise for older adults with heart disease
This study tests whether a personalized exercise program can help older people (60–75) with stable coronary heart disease improve their heart health. You would work with healthcare professionals to get an exercise plan tailored to your condition.
Nanjing, JiangsuAges 60–75 - NCT07514962Recruiting
Minimally invasive heart bypass surgery with a blood-thinner medication
This trial tests whether a blood-thinner drug called cangrelor helps patients who are having a special type of bypass surgery that uses a small incision instead of opening the whole chest. The surgery connects a healthy artery from your chest wall directly to a blocked heart vessel to restore blood flow.
Lugano, Ch/tiAges 18 years+ - NCT07511257RecruitingPhase 4
Blood thinners after heart attack with widened arteries
This trial tests two different blood-thinner strategies for people who have had a recent heart attack and also have a widened artery (ectasia) in the heart. The goal is to find the safest and most effective way to prevent another heart attack or clot.
Mexico City, TlalpanAges 18–80 - NCT06082063RecruitingPhase 3
