Improving care after cardiac arrest to prevent another arrest
This trial tests a new approach to care for people who have had a cardiac arrest outside the hospital and have been revived by emergency services. The goal is to see if a structured treatment plan can prevent another arrest before reaching the hospital.

Transthyretin cardiac amyloidosis in internal medicine
This study looks back at medical records of patients who were diagnosed with transthyretin cardiac amyloidosis (a type of protein buildup in the heart) while hospitalized in internal medicine at Strasbourg University Hospitals between 2013 and 2023. It aims to describe their health journey and outcomes.
StrasbourgAges 18 years+ - NCT05914779Recruiting
Early antibiotics after out-of-hospital cardiac arrest
This study looks at whether starting antibiotics soon after an out-of-hospital cardiac arrest helps patients who are unlikely to have an infection. Antibiotics may prevent or treat infection-related complications, but only if certain infection and health conditions are met.
Doha, Baladiyat ad DawhahAges 18 years+ - NCT07238426Enrolling by invitation
Heart screening for older adults in Ordu, Turkey
This study is a screening program in Ordu, Turkey, to find older adults (65+) who might have a heart condition called cardiac amyloidosis. It uses medical records and heart ultrasounds to check people who already have certain heart problems.
Ordu, OrduAges 65 years+ - NCT07232277Recruiting
Vein congestion and kidney injury after heart surgery
This trial looks at how fluid buildup in veins might relate to kidney injury after planned heart surgery. It aims to find ways to prevent kidney damage. Participants must be having planned (non-emergency) heart surgery, be 18 or older, and have healthy kidneys and overall health.
Yangzhou, JiangsuAges 18 years+ - NCT07235865Recruiting
Blood test to find and monitor heart masses
This trial uses a blood test (liquid biopsy) to help find and monitor heart masses without surgery. It may help diagnose what the mass is and how it changes over time.
Milan, ItaliaAges 12 years+ - NCT07236398Enrolling by invitation
Modified left atrial maze procedure for atrial fibrillation
This trial tests a modified maze procedure to treat atrial fibrillation during heart surgery. It may help patients with AFib who are already scheduled for cardiac surgery.
Toulouse, French (France)Ages 18 years+ - NCT06914570Recruiting
Heart device effect on tricuspid valve and right heart
This study looks at how a new pacemaker or defibrillator (CIED) might affect the tricuspid valve and the right side of the heart. It aims to understand these changes over time.
Milan, MIAges 18 years+ - NCT06776419Recruiting
Heart inflammation and scarring in Fabry disease
This study uses advanced heart scans (PET/CT and MRI) to look at inflammation, blood vessel health, and scarring in the hearts of people with Fabry disease. It aims to better understand how Fabry disease affects the heart and find new ways to track or treat these changes.
CopenhagenAges 18 years+ - NCT07217236Recruiting
AI ECG to predict need for heart device
This trial uses artificial intelligence to analyze your ECG to see if you might be at risk for needing a heart device like a pacemaker. It's a way to check your heart health early.
TaipeiAges 65–90 - NCT07214350Recruiting
Physical Activity Barriers in Cardiac Rehab by Sex
This study looks at how men and women differ in getting started and staying active during and after cardiac rehab. You will use a mobile app to track your activity and answer questions, helping researchers find better ways to support heart health.
Durham, North CarolinaAges 18 years+ - NCT06572085RecruitingPhase 4
Butylphthalide for brain protection after cardiac arrest
This trial tests a medicine called butylphthalide (NBP) to see if it helps protect the brain after a cardiac arrest. It is for adults who remained unconscious after their heart was restarted.
Beijing, Beijing MunicipalityAges 18–80 - NCT07209098Recruiting
Heart failure study testing CCM therapy
This study tests a therapy called Cardiac Contractility Modulation (CCM) for people with heart failure. It uses a device to help the heart pump more strongly, and researchers compare it to standard care using patient records.
Marlton, New JerseyAges 18 years+ - NCT05197972Recruiting
Hypnosis and heart-breathing training to reduce cancer surgery anxiety
This study tests whether guided “heart-breathing” and hypnosis (through an app) can lower anxiety before cancer surgery. It may help you feel calmer in the days leading up to the operation.
Montpellier, HéraultAges 18 years+ - NCT07205393Recruiting
Heart rehab after valve replacement surgery
This trial tests a phase one cardiac rehabilitation program for people who have had their mitral or aortic heart valve replaced. It aims to see if the rehab helps recovery. You might qualify if you had planned (not emergency) valve surgery and are stable enough for light exercise.
QinaAges 40–55 - NCT07211282Recruiting
Activity tracking for late-stage cardiac rehab
This trial uses a smartphone app to monitor and guide your physical activity during the final phase of cardiac rehab. It aims to help you safely stay active and improve your recovery.
Edegem, AntwerpAges 18 years+ - NCT07196397Recruiting
