Sudden cardiac arrest

This study follows 2000 people who have or will get the OmniaSecure defibrillation lead, a wire that helps control dangerous heart rhythms. Researchers will track how often the lead causes problems over 5 years. The goal is to make sure the lead is safe and works as expected in e…

This study is tracking 100 adults who receive an EluPro antibiotic-eluting envelope during implantation of a heart device (like a pacemaker). The envelope slowly releases antibiotics to prevent infection. Researchers are monitoring complication rates in real-world use to see how …

This study tests a new device that combines two heart therapies: one to strengthen heartbeats and another to stop dangerous rhythms. About 300 adults with heart failure and a weak heart pump will get the device. Researchers will check if it safely converts life-threatening heart …

This study tests a new mapping method for ventricular tachycardia (VT) ablation that avoids purposely triggering VT. Instead, it uses special software to identify slow-conduction areas during normal heart rhythm. The goal is to see if this approach reduces VT recurrence, death, o…

This study planned to test whether a direct injection of potassium chloride could help people whose hearts had stopped and were not responding to standard shocks. The trial was withdrawn before any patients were enrolled, so no results are available.

This study is testing whether a wearable ECG patch, combined with AI analysis, can help doctors identify a wide range of heart conditions and risks from a single recording. The Cor360 system looks at many aspects of heart health at once, such as heart failure, rhythm problems, an…

This study examines how different hospital treatments—sedation, temperature control, and blood pressure management—after a cardiac arrest impact kidney function. Researchers will follow 3500 adults who were resuscitated from a heart attack outside the hospital. The goal is to und…

This registry follows 545 people with arrhythmia who received a heart ablation using the DiamondTemp system. Researchers will track how many stay free of their heart rhythm problem and how many have serious side effects over 12 months. The goal is to see how well the device works…

This study examines whether a low pulse pressure (the difference between top and bottom blood pressure numbers) in the first hours after a cardiac arrest is linked to early death. Researchers will analyze data from 3500 patients who had a cardiac arrest outside the hospital and a…

This study looks at whether a special PET scan can help doctors better predict sudden cardiac arrest in people with heart failure and blocked arteries. About 300 participants who already have a defibrillator will be followed to see if heart nerve damage, heart size, or blood mark…

This study follows over 5,700 people with coronary artery disease and mild heart damage to see if blood tests and ECGs can better predict who is at risk for sudden cardiac death. The goal is to find inexpensive markers that could help doctors decide who needs a defibrillator. Par…
