Würzburg, BavariaAges 18 years+ - NCT03303612Recruiting
Check monitoring vs guided pacing after valve replacement
This study compares two ways to decide when someone needs a pacemaker after they get a new heart valve (TAVI) and develop a new, persistent left bundle branch block (LBBB). It may help reduce unnecessary procedures while still keeping heart rhythms safe.
Edmonton, AlbertaAges 18 years+ - NCT07252856Recruiting
Digital support for heart rehab (phase III)
This trial tests a digital tool to help people with heart disease continue their cardiac rehabilitation at home during the maintenance phase. It's for people who have already completed the earlier rehab phase and are ready for long-term support.
LeuvenAges 18 years+ - NCT03253835Enrolling by invitation
MRI heart flow study to understand heart muscle damage
This study uses a special heart MRI to look at blood-flow patterns and how they relate to heart muscle injury. It may help researchers better understand different types of heart damage by comparing people with and without injury.
Graz, StyriaAges 20–80 - NCT02725060Enrolling by invitation
Study of autoimmune changes in postural tachycardia syndrome
This trial studies whether an autoimmune (immune system–related) process is involved in postural tachycardia syndrome (POTS), a condition where your heart rate rises when you stand. The study may help researchers understand what causes POTS and how it could be treated or monitored.
Oklahoma City, OklahomaAges 18–50 - NCT02013284Enrolling by invitation
Stool test to see if gut microbes predict heart risk
This study looks at your gut bacteria (from a stool sample) to see whether they can help predict heart risk in people being checked for blocked heart arteries. Your results may help researchers understand who is at higher risk and why.
Rochester, MinnesotaAges 18 years+ - NCT07401836Recruiting
Sleep bundle for heart surgery patients
This trial tests a special sleep program (bundle) to help patients sleep better after heart surgery. Researchers want to see if it improves recovery and well-being.
Saint John, New BrunswickAges 19 years+ - NCT07402642Recruiting
Early Education to Lower Heart Attack Risk Factors
This trial tests if personalized education after a heart attack helps patients lower their future risk of heart problems. It focuses on people who had an emergency procedure to open blocked arteries.
Las Palmas de Gran Canaria, Las PalmasAges 18 years+ - NCT07405229RecruitingPhase 4
Medical treatment for idiopathic ventricular fibrillation patients
This study tests medical treatments for people who survived a cardiac arrest with a specific heart rhythm problem called idiopathic ventricular fibrillation. If your cardiac arrest was likely from a heart issue but not from clogged arteries, you might help find better treatments.
Copenhagen, Dr.Ages 18 years+ - NCT07410481Recruiting
Therapy for PTSD after a cardiac arrest
This study compares two talking therapies for PTSD after a cardiac arrest. One combines mindfulness and acceptance with gradual exposure to difficult memories; the other focuses on present life challenges. Both aim to reduce distress and improve quality of life.
New York, New YorkAges 18–81 - NCT07414251Recruiting
Preparing children for heart procedures
This study looks at how children prepare for heart surgery or a heart catheterization. It will ask families to fill out questionnaires to help improve preoperative care.
Berlin, State of BerlinAges Up to 18 years - NCT07420400Recruiting
Detecting heart shunts without needles
This trial uses a specialized ultrasound test (TEE with bubble study) to find a small opening in the heart called a PFO. It may help people who need this test to check for causes of certain health problems.
La Jolla, CaliforniaAges 18 years+ - NCT07420712Recruiting
A Nerve Block for Minimally Invasive Heart Surgery
This study tests a pain-relieving nerve block for the back (serratus posterior superior plane block) given before minimally invasive heart bypass surgery. It aims to see if this block helps with pain control and recovery after surgery.
IstanbulAges 18–75 - NCT07422129Recruiting
Aortic wall analysis during heart surgery
This study looks at the structure and strength of the aorta (the main artery from your heart) in patients having surgery to replace part of it or having a heart transplant. The goal is to better understand the aortic wall to improve future treatments.
Pavia, LombardyAges 18 years+ - NCT07430007Recruiting
Exercise and diet to reduce AFib burden
This study tests whether a program of exercise and healthy eating changes can reduce how often atrial fibrillation (AFib) happens and help you lose weight. It may be a good fit if you are overweight, have AFib, and are ready to make lifestyle changes.
Jyväskylä, Central FinlandAges 18–75 - NCT07430553Recruiting
Comparing pacemakers for better heart function in heart failure
This trial compares three types of advanced pacemakers (cardiac resynchronization therapy devices) to see which works best for improving heart function and reducing abnormal heart rhythms in people with heart failure.
London, Greater LondonAges 18 years+ - NCT07430813Recruiting
Drone delivery of defibrillators for bystanders
This study tests if drones can deliver a defibrillator to people who witness a cardiac arrest, helping them provide lifesaving care before an ambulance arrives. You may be asked to use a training manikin to see how quickly you can help.
Guildford, SurreyAges 18 years+ - NCT07431710Recruiting
AI-guided chest compressions for cardiac arrest in the ER
This trial tests whether artificial intelligence (AI) can help doctors give better chest compressions during CPR for adults whose hearts stopped outside the hospital. The goal is to improve blood flow and outcomes without using special equipment in the ambulance.
New Taipei City, BanqiaoAges 20 years+ - NCT07444398RecruitingPhase 1
Vericiguat for worsening heart failure
This trial tests if adding vericiguat to standard heart failure medicines helps people hospitalized with worsening heart failure. It's for those with a weak heart pump and high NT-proBNP levels.
Rawalpindi, Punjab ProvinceAges 25–65 - NCT07455292Recruiting
Heart valve study using advanced MRI
This study uses a special type of MRI, called 4D flow MRI, to better understand how severe aortic stenosis (a narrowed heart valve) affects heart function. It may help doctors learn more about different types of this condition and improve future treatment.
