This study looks at whether people with atrial fibrillation can safely stop taking long-term blood thinners after a procedure that closes off a part of the heart called the left atrial appendage. Participants will get a reduced dose of the blood thinner apixaban for just 3 months…

This study looks at two ways to prevent another stroke in older adults who have a hole in the heart (PFO) and had a stroke from an unknown cause. One option is a procedure to close the hole, plus lifelong blood thinners. The other is taking blood thinners alone. Researchers will …

This study compares a stent (CARESTO® heal) plus standard medication against medication alone in 536 people who recently had a stroke or retinal artery blockage due to a specific type of carotid artery disease that is not severely narrowed. The goal is to see if the stent can low…

This study is looking for markers in blood and saliva that can quickly tell if a person is having a stroke, and what kind. Researchers will collect samples from 650 adults with suspected stroke within 24 hours of symptoms. The goal is to develop a fast, accurate test to help emer…

This study tests a wearable ECG patch (MEMO Patch) to see if it can detect atrial fibrillation—a heart rhythm issue that raises stroke risk—in 100 people who had a stroke with no known cause. Participants wear the patch for up to 14 days at home, and results are compared with sta…

This study looks at 92 people who had a stroke with no clear cause and received a small heart monitor. Researchers will use an artificial intelligence program called SmartECG-AF to analyze their ECGs and predict who might develop atrial fibrillation (an irregular heartbeat) in th…

This study looks at whether a heart ultrasound technique called left atrial strain can predict stroke risk in people who had a stroke with no known cause. Researchers will measure heart function in 900 adults and track who has another stroke. The goal is to find a safe, low-cost …

This study will follow 500 people who have had a stroke and also have atrial fibrillation (an irregular heartbeat). Some were taking blood thinners when they had their stroke, others were not. Researchers want to understand why blood thinners fail in some patients, by looking at …
