Testing an online decision aid for heart and kidney disease
This study is testing an online tool called 'My Heart and CKD' that helps people with both chronic kidney disease and heart disease make decisions about their care. The goal is to see if it is easy to use and helpful for patients and their doctors.
Calgary, AlbertaAges 18 years+ - NCT06921356Recruiting
Grocery delivery plus lifestyle program for high blood pressure and diabetes
This study tests whether a program that delivers healthy groceries along with lifestyle coaching can help people with high blood pressure and type 2 diabetes manage their conditions better. If you qualify, you'll receive support to improve your eating habits and health.
Baltimore, MarylandAges 18 years+ - NCT06921603Recruiting
Ultrasound-guided diuretics for heart failure
This trial tests whether using a bedside ultrasound to guide diuretic treatment improves outcomes in people hospitalized for worsening heart failure. It may help find the right dose of IV diuretics faster.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06922409Recruiting
Light therapy for stroke recovery in rehabilitation
This trial tests whether exposure to naturalistic light can help reduce fatigue and depression after a stroke. It is designed for patients in a rehabilitation unit who are able to communicate and cooperate with simple physical exams.
Glostrup Municipality, Capital RegionAges 18 years+ - NCT06922526Recruiting
Pacemaker and tricuspid valve health: long-term outcomes
This study looks at how pacemakers and similar heart devices affect the tricuspid valve over time and whether that leads to worse health outcomes. It may help you understand if your device is causing long-term changes.
JinanAges 18 years+ - NCT06922851Recruiting
Protein filter therapy for dilated cardiomyopathy
This trial tests a protein filtering treatment (immunoadsorption) for people with dilated cardiomyopathy who have a specific antibody linked to heart damage. It aims to see if removing these antibodies can improve heart function.
Wuhan, HubeiAges 18–75 - NCT06922994RecruitingPhase 2
Testing atorvastatin for arrhythmogenic cardiomyopathy
This trial tests if a common cholesterol medicine, atorvastatin, can slow the progression of arrhythmogenic cardiomyopathy, a genetic heart condition that can cause abnormal heart rhythms. If you have this condition, joining this study may help researchers find a new way to protect your heart.
Pavia, PVAges 18 years+ - NCT06923072RecruitingPhase 2
Baricitinib for neurological Kohlmeier-Degos disease
This trial tests if the drug baricitinib can help people with Degos disease that has affected their brain or nerves. It aims to control inflammation and improve symptoms.
Bethesda, MarylandAges 18–99 - NCT06924593Recruiting
Shunt for carotid artery narrowing
This study tests a new device that is placed through the carotid artery in the neck to temporarily block blood flow during a procedure to open up a narrowed carotid artery. It might be an option for people who have high-risk features that make traditional surgery more challenging.
BeijingAges 18 years+ - NCT06925178Recruiting
Imaging database study for recent stroke patients
This study is building a standard imaging database for people who have recently had a stroke. By participating, you will help doctors better understand how to use different types of scans to diagnose and treat cerebrovascular disease.

Blood flow monitoring for carotid artery surgery
This trial is testing a special way to monitor blood flow during carotid artery surgery to help keep patients safe. It may be a good fit if you are having planned carotid surgery and meet a few basic health criteria.
RomeAges 18 years+ - NCT06926959Recruiting
Tricuspid regurgitation risk model study
This study aims to develop a risk model for tricuspid regurgitation, a condition where the heart valve doesn't close properly. It may help doctors better understand and treat this condition.
Guangzhou, GuangdongAges 18 years+ - NCT06927206Recruiting
Vibration and muscle stimulation for leg function after stroke
