Study of Aging Blood Vessels and a Protein Called SNRK
This research study examines how blood vessels age over time and how a protein called SNRK may be involved in that process. Researchers want to understand vascular aging (how blood vessels become less flexible as we get older) to potentially help prevent heart and stroke problems.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT07591987Recruiting
Breathing Techniques to Reduce Shortness of Breath After Heart Surgery
This study tests whether special breathing exercises can help reduce shortness of breath and improve heart and lung function in patients recovering from open-heart surgery. You would learn and practice these breathing techniques before and after your surgery.

Minocycline after stroke clot removal surgery
This trial tests whether minocycline, an antibiotic, can reduce brain damage when given after successful clot removal surgery for acute stroke. The goal is to see if this medication helps patients recover better.
Wuhan, HubeiAges 18 years+ - NCT07594301RecruitingPhase 2/Phase 3
Minocycline after successful stroke clot removal in the back brain
This study tests whether an antibiotic called minocycline can reduce brain damage after doctors successfully remove a blood clot from the back of the brain (posterior circulation stroke) using a catheter procedure. The drug may help protect brain tissue and improve recovery.
Wuhan, HubeiAges 18 years+ - NCT07594704Recruiting
Comparing catheter placement methods for long-term IV access
This study compares two different techniques for placing a special long IV catheter (PICC) in your arm. The catheter stays in place for weeks or months to deliver medications or fluids. Researchers want to see which placement method works better and causes fewer problems.
Guangzhou, GuangdongAges 18–75 - NCT07595016Recruiting
Testing a Blood Pressure Device for Pregnant Women
This study tests whether a new Withings blood pressure monitor (BPM Pro 2) accurately measures blood pressure in pregnant women, including those with pregnancy-related high blood pressure (preeclampsia). Accurate home blood pressure monitoring could help keep you and your baby safer during pregnancy.
Yerevan, ArmeniaAges 18 years+ - NCT07595354Recruiting
Safe Exercise Plan for Young People at Risk of Heart Disease
This study helps children and teens who may be at risk for a heart condition called HCM learn safe ways to exercise. Researchers will create a personalized exercise plan and check in regularly to see how it goes.
LiverpoolAges 10–18 - NCT07595718Recruiting
AI Study of Disease Patterns and Health Data
This research uses artificial intelligence to analyze health information from adults to better understand and predict when major diseases like diabetes, heart disease, and cancer might develop. Your participation could help scientists discover new patterns that improve early detection.
Seoul, Seoul Special CityAges 30–60 - NCT07596394Recruiting
Registry of Catheter-Based Aortic Valve Replacements
This registry collects information about patients who receive a new valve inserted through a catheter (a thin tube) rather than open surgery. It tracks how well the procedure works and any side effects to help doctors understand the long-term safety and effectiveness of this less invasive approach.
Pavia, PaviaAges 18 years+ - NCT07596446Recruiting
Emergency treatment study for cardiac arrest patients
This study tests emergency treatments for people who have had a cardiac arrest (heart stops beating) outside the hospital. It looks at two groups: people whose hearts stop despite CPR efforts, and people whose hearts have restarted. The goal is to see if these treatments can help patients survive and recover better.
PragueAges 18–70 - NCT07596966Recruiting
Propolis and Royal Jelly for High Blood Pressure
This study tests whether two bee products—propolis and royal jelly—can help reduce inflammation and stress in the body of people with high blood pressure. Researchers want to see if adding these supplements to your current blood pressure medication helps control the condition better.
Niterói, Rio de JaneiroAges 18–75 - NCT07597031Recruiting
Digital Lifestyle Platform for People Leaving Hospital Rehab
This study tests whether a smartphone or tablet app can help people stay healthy and active after leaving rehabilitation. The app guides you through daily activities and healthy habits to support your recovery at home.
