Blood-thinner plan study for people with high bleeding risk after PCI
This trial studies which blood-thinner (antiplatelet) strategy is safest and most effective for people at high risk of bleeding after a procedure called PCI. It also looks at longer-term outcomes and whether adjusting treatment can improve safety without losing heart protection.
Sichuan, SichuanAges Any age - 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+ - 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 - NCT06742931Recruiting
Balloon vs stent for heart artery blockages in high bleeding risk patients
This trial compares a drug-coated balloon (medicated balloon) to a drug-eluting stent (medicated mesh tube) for treating new blockages in heart arteries. It is designed for patients with a high risk of bleeding who have completed a short course of anti-clotting medication and have been event-free for at least one year.
AnsanAges 19 years+ - NCT06957366Recruiting
Managing Blood Thinners Before High-Risk Surgery
This study looks at how to safely manage your blood thinner (DOAC) around the time of a planned, high-bleed-risk surgery or procedure involving a spinal needle. The goal is to find the best way to stop and restart your medication to prevent bleeding and clotting problems.
Hartford, ConnecticutAges 18 years+ - NCT07230847Recruiting
Healing of drug-coated vs. standard stents in high-bleeding-risk patients
This trial compares two types of stents (a drug-coated stent and a standard drug-eluting stent) in people with acute coronary syndrome who also have a high risk of bleeding. It uses a special camera to look at how the artery heals one month after the stent is placed.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06623110RecruitingPhase 2
RP2 vaccine to prevent mouth cancer in high-risk pre-cancer
