Imaging tests for people before aortic valve replacement
This trial studies heart imaging tests (from multiple types of scans) for people who have a narrowed aortic valve and are being checked for a valve replacement through the catheter (often called TAVI). It may help doctors better plan the procedure and understand heart function before treatment.
Düsseldorf, North Rhine-WestphaliaAges 18 years+ - NCT00181259Recruiting
MRI scan study of heart muscle chemistry
This trial uses a special MRI scan to look at how the heart muscle uses fuel. It may help researchers understand heart conditions like dilated cardiomyopathy and coronary artery disease, especially in people with reduced heart pumping.
Baltimore, MarylandAges 18 years+ - NCT01670383Recruiting
Study sample collection for sepsis and after cardiac arrest
This trial collects and stores small samples from people in the ICU who are either being treated for sepsis or who have survived a non-traumatic cardiac arrest. It may help researchers better understand how the body changes after severe infection or after revival, which could improve future care.
SeoulAges 16 years+ - NCT01076660Recruiting
MRI study to predict sudden cardiac death risk
This trial uses heart MRI images and measurements to look for warning signs that could predict sudden cardiac death. It focuses on people with significantly reduced heart pumping function who are being considered for an ICD to prevent sudden death.
Newark, DelawareAges 21–80 - NCT00243776Recruiting
Study of heart tissue changes during certain heart surgeries
This study collects and analyzes small samples of heart tissue during specific heart operations in babies or children. The goal is to better understand how the heart develops after birth, which could improve future care.
Atlanta, GeorgiaAges Up to 20 years - NCT01728597Recruiting
Cardiac MRI scan without contrast for normal imaging values
This study measures normal heart images using an MRI scan without contrast dye. It’s meant to improve and standardize how doctors collect heart images for future patients.
Graz, StyriaAges 18–80 - NCT01999140Recruiting
ICD and CRT-D device registry for patients worldwide
This trial is a real-world registry that collects information from people who receive an implantable heart defibrillator or related device. It helps doctors understand how these devices are used and how patients do over time.
Washington D.C., District of ColumbiaAges Any age - NCT00271180Recruiting
Tracks long-term performance of Medtronic heart devices
This study follows how well certain Medtronic heart devices work over the long term. You may be included if you have a qualifying Medtronic implant and the research team can reliably get your implant and follow-up information.
Birmingham, AlabamaAges Any age - 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+ - NCT02488876Recruiting
Banking heart tissue samples after cardiac surgery
This study collects tissue samples from people who are having heart surgery and stores them in a database to better understand the body’s inflammatory (immune) response after surgery. Your participation may help researchers learn why inflammation happens and how to improve care after surgery.
Aachen, North Rhine-WestphaliaAges Any age - NCT02355457Recruiting
Blood marker study in new heart attack symptoms
This study looks at blood “biomarkers” (signals in blood tests) in people who arrive with symptoms that could be a heart attack. It may help doctors spot and manage acute heart problems sooner and more accurately.
HamburgAges 18 years+ - NCT02381301Recruiting
Blood and heart CT scan tests for heart blood-flow markers
This study looks at whether certain lab “biomarkers” and a heart CT scan can help understand heart blood flow in people getting routine coronary CT angiography (CCTA). It may be useful for improving how doctors assess heart health from scan and blood results.
Maastricht, LimburgAges 18 years+ - NCT02708134Recruiting
