This study looked at whether using ultrasound to guide vein puncture reduces complications like bleeding or false aneurysms in people undergoing ablation for atrial fibrillation. Over 1,000 adults scheduled for the procedure were enrolled. The study was terminated early, so resul…

This study tested whether fentanyl, a painkiller used during heart stent procedures, reduces the effectiveness of ticagrelor, a blood thinner given to prevent clots. Researchers compared crushed versus whole ticagrelor pills in 45 patients. The trial was stopped early, so results…

This study aimed to compare two ways of setting breathing machine pressure (PEEP) in patients with severe lung injury (ARDS). The goal was to see which method better protects the lungs and heart. Only 2 patients were enrolled before the study was stopped, so no meaningful results…

This study aimed to find out how many people experience short-term and long-term pain after a specific type of heart surgery called one-stage hybrid arrhythmia ablation. Researchers surveyed patients who had the procedure at UZ Brussels to see what factors, like medications or ge…

This study aimed to see if a non-invasive device using light (near infrared spectroscopy) could measure how well the heart is pumping in children with heart failure during routine clinic visits. Only 3 children took part before the study was stopped early. The goal was to find a …

This pilot study aimed to see if antiseizure drugs like phenobarbital and levetiracetam change brain connectivity patterns in people with severe acute brain injury and reduced consciousness. Only 5 participants were enrolled before the study was terminated. Researchers used resti…

This study looked at whether a wearable defibrillator (WCD) can accurately record heart sounds in people with heart failure. About 60 adults with heart failure and weak heart pumping (ejection fraction 40% or less) took part. The goal was to compare the WCD's recordings to a stan…

This study aimed to see if a wireless sensor could collect health information from babies with heart defects at home, replacing wired devices. Only 2 infants were enrolled before the study was stopped. The goal was to understand if the wireless device was easy to use and worked w…

This study looked at whether proteins that control our body's daily rhythms (clock proteins) can predict how severe asthma will get. Researchers monitored these proteins in the blood and sputum of 50 adults with severe eosinophilic asthma before and during treatment with mepolizu…

This study looked at whether an early heart MRI can help doctors know which patients with severe heart damage after a heart attack will get better on their own. The goal was to see if MRI could identify patients who would benefit from getting a defibrillator sooner rather than wa…

This study aims to find out how common transthyretin amyloidosis cardiomyopathy (ATTR-CM) is in Russian patients with a certain type of heart failure. Researchers will review medical records and then invite some patients for extra heart tests to confirm or rule out ATTR-CM. The g…

This pilot study tested an e-health system that uses tele-monitoring, tele-notification, and tele-coaching to help manage adults with at least two chronic conditions like heart failure, COPD, or diabetes. The goal was to see how well the system could detect health problems early.…
