Preventing heart events in people with type 2 diabetes
This trial tests a heart-focused prevention approach to lower the risk of cardiac (heart) events in adults with type 2 diabetes. It may help by targeting early stress on the heart measured with a specific blood test.
Mödling, Lower AustriaAges 18 years+ - NCT05718128RecruitingPhase 4
Study of taking heart muscle samples from the inside
This trial studies patients who need an endocardial myocardial biopsy, meaning a small heart muscle sample taken from inside the heart. It’s meant for people with heart problems whose cause is not clearly known and may help doctors learn more about what’s going on.
Hangzhou, ZhejiangAges 18–80 - NCT05746793Recruiting
IVF pregnancy study to prevent pre-eclampsia in high-risk women
This trial studies ways to lower the risk of pre-eclampsia (dangerous high blood pressure in pregnancy) in women who are having a first pregnancy through IVF/ICSI or who have PCOS. It’s aimed at people considered higher risk for pre-eclampsia.
BrusselsAges 18–48 - NCT05635877RecruitingPhase 4
Low-dose heart-rate medicine after surgery in frail older adults
This trial tests whether a low dose of esmolol (a short-acting heart-rate medicine) can reduce heart muscle injury after non-heart surgery in older, frail people. It may help lower the chance of heart-related complications around the time of surgery.
Jinan, ShandongAges 65–90 - NCT01653223Recruiting
Simvastatin to protect the heart during heart surgery
This trial looks at whether simvastatin (a cholesterol medicine) can help protect the heart during cardiac surgery. You might be invited if you’re having surgery for certain, non-complex heart conditions, but not if you have some specific related health problems.
Guangzhou, GuangdongAges 18 years+ - NCT05089162Recruiting
Testing a heart ultrasound approach in chronic heart failure
This study looks at people with chronic heart failure with weaker pumping function and checks how well a lung/heart ultrasound can assess congestion (fluid buildup). If you qualify, you may help test a better way to evaluate your condition during a planned hospital visit.
Vandœuvre-lès-NancyAges 18 years+ - NCT04332692Recruiting
Check if a lung ultrasound helps evaluate discharge after heart failure
This study looks at whether doing lung ultrasounds can better assess people right before they leave the hospital after an acute heart failure flare. It may help doctors decide when someone is ready for discharge and tailor care to reduce risk after leaving.
Vandœuvre-lès-NancyAges 18 years+ - NCT05097898Recruiting
Check fluid buildup in heart failure with normal pumping
This study evaluates how well doctors can assess “fluid congestion” in people with chronic heart failure where the heart’s squeezing is still preserved. It may help improve how patients are monitored during hospital visits.
Vandœuvre-lès-NancyAges 18 years+ - NCT05089149Recruiting
Check how lung ultrasound helps manage heart failure congestion
This study looks at people with long-term worsening heart failure who are coming to the hospital for a planned visit, to see how checking “congestion” (fluid buildup) may guide care. It may help the team understand whether lung ultrasound can better assess who needs treatment changes.
Vandœuvre-lès-NancyAges 18 years+ - NCT05944146Recruiting
Tests two methods for measuring heart blood flow during surgery
This trial compares a neck ultrasound test (carotid Doppler) with a heart monitoring method (thermodilution) to see if they give consistent blood-flow readings. It may help clinicians measure circulation more reliably in people having heart surgery.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05942729Recruiting
Checking heart disease diagnosis using echo images and health data
This study looks at how well heart ultrasound (echocardiography) images and clinical information can be used to diagnose cardiac conditions. If you have a clear ultrasound study already or can get one with good image quality, your information may help improve diagnostic accuracy.
Pierre-BéniteAges 18 years+ - NCT05962190Recruiting
Short-term extra fat intake to study liver metabolism
