Aspirin plus ticagrelor or clopidogrel for minor stroke
This trial tests whether adding aspirin to either ticagrelor or clopidogrel (two antiplatelet medicines) can help prevent another stroke in people who recently had a minor stroke or TIA affecting a large brain artery. It is for people who started antiplatelet treatment within 24 hours of their symptoms.
Kafr ash ShaykhAges 18–75 - NCT06591377RecruitingPhase 3
Aspirin plus a second drug for minor stroke or TIA
This trial tests whether adding ticagrelor or cilostazol to aspirin is better than aspirin alone for preventing another stroke. It is for patients who recently had a minor stroke or a transient ischemic attack (TIA) caused by a blockage in a large artery.
CairoAges 18–75 - NCT06588595RecruitingPhase 4
Switching Blood Thinners After Stent Placement
This study compares two ways to manage blood thinners after a stent. It tests whether switching from stronger drugs (prasugrel or ticagrelor) to clopidogrel is safe and effective for long-term heart protection.
Jacksonville, FloridaAges 18 years+ - NCT06451198RecruitingPhase 4
Indobufen vs aspirin after stent in older heart patients
This trial tests whether a blood thinner called indobufen works as well as aspirin for older people (65+) who have had a heart attack or unstable angina, received a drug-eluting stent, and are already taking two blood thinners. The goal is to find a safer or better option for long-term prevention.
Shanghai, Shanghai MunicipalityAges 65 years+ - NCT06336174Recruiting
Thinking and Memory in Brain Artery Narrowing: A Study
This study looks at how severe narrowing of brain arteries may affect memory and thinking over time. It involves people who have had a mini-stroke or mild stroke and aims to understand the changes in cognitive function.
Hefei, AnhuiAges 18–80 - NCT06281665RecruitingPhase 4
Aspirin after preeclampsia: the TAP trial
This trial tests whether taking low-dose aspirin after giving birth can help people who had preeclampsia. It aims to see if aspirin can lower the risk of future heart problems.
Pittsburgh, PennsylvaniaAges 18–55 - NCT06168461RecruitingEarly Phase 1
Can daily aspirin help after preeclampsia?
This study tests whether taking a low-dose aspirin every day can help improve blood vessel health in people who had preeclampsia within the past 5 years. The goal is to see if aspirin can lower the risk of future heart problems.
Iowa City, IowaAges 18–50 - NCT05709483RecruitingEarly Phase 1
Aspirin plan test to predict who avoids preeclampsia
This study looks for blood markers that may predict whether low-dose aspirin will “work” to prevent preeclampsia in a next pregnancy. It may help improve which patients benefit most from aspirin and guide safer prevention in future pregnancies.
New York, New YorkAges 18–45 - NCT05885932Recruiting
Stent treatment versus medicines for blocked neck artery
This study compares a drug-coated stent placed in a neck (vertebral) artery versus best medical treatment with medicines and risk-factor control. It aims to reduce problems caused by a badly narrowed artery after recent stroke-like symptoms.
BeijingAges 18 years+ - NCT05868525RecruitingPhase 4
Compare two aspirin doses after blunt vessel injury
This trial tests whether taking a lower-dose aspirin (81 mg) works as well as a higher-dose aspirin (325 mg) to prevent stroke after a blunt injury that affects blood vessels in the neck/head. It may help some patients lower their stroke risk with the simplest, safest dose.
Loma Linda, CaliforniaAges 18 years+ - NCT05638867RecruitingPhase 4
Blood thinner choice guided by risk score for heart attack patients
This trial is testing whether a newer type of blood thinner (called a NOAC) can be used safely right after a heart attack or related event, in addition to the standard two antiplatelet medicines. It focuses on patients who have higher risk signs, like elevated D-dimer levels or a higher PARIS risk score, to see if this approach is safe and effective at preventing future heart problems.
