Triage approach for certain strokes from blocked large brain arteries
This trial studies a way to sort and treat people with a specific type of acute ischemic stroke (caused by a blockage in a large brain artery). It may help doctors choose the best next steps—either a procedure or medication—faster and more appropriately.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05811364Recruiting
Stent versus bare-metal treatment for blocked leg arteries
This study compares a new balloon-expandable stent to standard bare-metal stenting to treat complex blockages in the iliac arteries (main blood vessels to the legs). It may help people with symptoms like leg pain with walking, pain at rest, or minor tissue injury by improving blood flow and reducing repeat procedures.
Little Rock, ArkansasAges 18 years+ - NCT05898269Recruiting
Predicting fluid needs while lying face down in ARDS
This study tests a way to predict whether you will benefit from a fluid bolus (a small amount of IV fluid) while you are lying face down for ARDS. It uses continuous heart monitoring to guide or evaluate fluid decisions and may help clinicians avoid too much or too little fluid.
Clermont-FerrandAges 18 years+ - NCT05899582Recruiting
Heart-bypass–like brain surgery for artery blockage patients
This trial studies whether a special bypass surgery can improve symptoms in people with a long-term (chronic) blockage of the middle brain artery. It aims to improve brain blood flow and reduce future stroke risk in the right patients.
BeijingAges 18–65 - NCT05951101Recruiting
Device to close an irregular heartbeat heart pocket safely
This trial tests the Zenith system, a device that seals off a heart area called the left atrial appendage to reduce stroke risk in people with atrial fibrillation (AF). You may be eligible if you have AF and a doctor recommends LAA closure, and you can return for follow-up scans and visits.
Parkville, VictoriaAges 18 years+ - NCT05961748Recruiting
Brain and heart illness registry for adults in China
This study is a registry that collects health information from adults who have certain new heart and/or brain conditions. It may help researchers understand how these problems occur together and improve future care planning.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05972018RecruitingPhase 4
Liposomal numbing medicine for belly incisions in vascular surgery
This study compares two numbing options for pain control after open belly (mid-abdominal) vascular surgery: a longer-lasting numbing drug in the belly muscle layer versus a different numbing drug and catheter. It aims to see which approach better reduces postoperative pain and opioid use, and may help improve recovery.
Hartford, ConnecticutAges 18–80 - NCT05983757Recruiting
Clot retrieval for smaller brain artery strokes
This trial tests if removing clots from smaller arteries in the brain (not the main ones) helps people who had a stroke and can't get standard clot-busting medicine. It compares clot removal to usual care for strokes caused by these medium-sized vessel blockages.
Atlanta, GeorgiaAges 18 years+ - NCT06082466Recruiting
Comparing two types of leg bypass surgery
This study compares two types of bypass surgery for blocked leg arteries. One uses a standard vein from your own body, and the other uses a vein supported by a special metal frame. The goal is to see which works better and lasts longer.
SalzburgAges 18 years+ - NCT06096142Recruiting
New Stent for Dialysis Access Blockages
This trial tests a new stent to open narrowed or blocked areas in dialysis access (fistula or graft). It may help improve blood flow so dialysis works better.
Salvador, Estado de BahiaAges 18 years+ - NCT06137521Recruiting
