Shorter blood thinner after hip replacement: a recovery study
This study tests a shorter course of blood thinner medication (rivaroxaban) after hip replacement surgery, following an enhanced recovery plan. It aims to see if a shorter treatment can safely prevent blood clots and help you recover faster.
Linz, Upper AustriaAges 18–85 - NCT06611579Recruiting
Study of the MonarQ System for Leaky Tricuspid Valve
This study tests a new device called the MonarQ TTVR System, which is placed through a small tube in a blood vessel to fix a leaky tricuspid valve without open-heart surgery. It is for people with severe tricuspid regurgitation symptoms that are not relieved by heart failure medicines alone.
Los Angeles, CaliforniaAges 18 years+ - NCT06611696RecruitingPhase 4
Avacopan vs lower-dose steroids for new vasculitis
This study compares a new drug (avacopan) with lower doses of steroids to standard steroid treatment for people newly diagnosed with ANCA-associated vasculitis. The goal is to see if avacopan can control your disease with fewer steroid side effects.
Toyoake, Aichi-kenAges 18 years+ - NCT06611787Recruiting
Registry study for congenital heart disease
This study collects information from people with congenital heart disease (a heart problem you're born with) over their entire life to better understand the condition and improve future care.
Beijing, Beijing MunicipalityAges Any age - NCT06612099Recruiting
Aerobic vs Pilates exercise for high blood pressure
This study compares two types of exercise—aerobic training (like brisk walking) and mat Pilates—to see which one better lowers blood pressure and improves daily function and quality of life in people with high blood pressure.
Istanbul, EyüpAges 25–70 - NCT06612359RecruitingPhase 1
Boost gait program for walking after stroke
This program tests a special walking training (BOOST GAIT) for people who have had a first stroke and are still learning to walk again. It aims to help you walk better and be more active in daily life.
Herk-de-Stad, LimburgAges 18 years+ - NCT06612710RecruitingPhase 1
A study of NouvSoma001 for recent stroke recovery
This trial tests a new treatment called NouvSoma001 for people who have had an ischemic stroke within the last week. It aims to see if the treatment is safe and helps improve muscle strength and overall recovery.
Wuhan, HubeiAges 18–75 - NCT06612723Recruiting
How Often to Exercise After a Stroke
This study tests whether exercising more often (high frequency) or less often (low frequency) helps people who had a stroke more than 6 months ago walk better. You'll do high-intensity walking workouts, and the goal is to see which schedule gives the most improvement.
Indianapolis, IndianaAges 18–85 - NCT06613074Recruiting
Smartphone app for stroke triage without ambulance
This trial is testing a smartphone app that helps guide patients with a recent stroke to the right place for care, if they did not come by ambulance. It is for people who have already received clot-busting treatment.
Shaoxing, ZhejingAges 18 years+ - NCT06613256Recruiting
Study of blood vessel cells in different inflammatory conditions
This study looks at blood vessel cells in three groups: healthy adults, patients having major surgery, and critically ill patients with sepsis. It aims to understand how these cells change in different types of inflammation.
Guildford, SurreyAges 18 years+ - NCT06614270Recruiting
CAR-NK cell therapy for severe autoimmune diseases
This trial tests a new type of immune cell therapy using modified natural killer cells (CAR-NK) that target a protein called CD19 and produce helpful signals (IL-10 and IL-15). It is for people with certain autoimmune diseases that have not improved with standard treatments or have come back after getting better.
Hangzhou, ZhejiangAges 18–65 - NCT06615102RecruitingPhase 3
Testing if angiotensin II prevents kidney injury after heart surgery
This trial tests whether giving a medicine called angiotensin II during heart surgery can help prevent acute kidney injury (a sudden drop in kidney function). It is for adults having certain types of heart surgery who have a higher risk of kidney problems.
BerlinAges 18 years+ - NCT06615596RecruitingEarly Phase 1
Stopping blood thinners after successful atrial fibrillation ablation
This trial tests whether it is safe to stop taking blood thinners (anticoagulants) after a successful ablation procedure for atrial fibrillation. If you have had no AF for 3 months after your first ablation, you may be able to stop these medications, reducing your risk of bleeding.
Boston, MassachusettsAges 18 years+ - NCT06615609Recruiting
Heart health management after bypass or stent
This trial tests a smartphone-based program to help people manage their blood pressure, blood sugar, and cholesterol after heart procedures like bypass surgery or stenting. It aims to improve long-term heart health.
