ATRIAL FIBRILLATION (AF)

This study tests a device called Amulet 2 that is implanted in the heart to seal off a small pouch (the left atrial appendage) where blood clots can form in people with atrial fibrillation. The goal is to reduce the risk of stroke without needing long-term blood thinners. About 4…

This study looks at whether doing a heart procedure called cryoablation right away in the emergency room can help people with recent atrial fibrillation (AFib). About 350 adults with AFib that started within the past year will be randomly assigned to get either immediate ablation…

This study looks at whether measuring blood pressure inside the heart's left upper chamber during a procedure for atrial fibrillation (an irregular heartbeat) can spot patients with hidden heart failure. If the pressure is high, patients get a heart failure checkup and medication…

This study compares two ways to repeat a heart ablation for people with persistent atrial fibrillation (AF) whose first ablation didn't work. The standard repeat method isolates the pulmonary veins; the experimental method also treats the left atrial posterior wall. Researchers w…

This study compares two ways of doing a heart procedure called catheter ablation for people with atrial fibrillation (an irregular heartbeat). One method uses X-rays to guide the doctor, and the other does not. The goal is to see if the no-X-ray method works just as well and is a…

This phase 2 study compares abelacimab, a new biologic blood thinner, to the standard drug rivaroxaban in 1,287 people with atrial fibrillation who are at moderate-to-high risk of stroke. The goal is to see if abelacimab causes fewer major or clinically relevant bleeding events w…

This study tests whether one-on-one education from a trained pharmacist can help people with atrial fibrillation take their blood thinners (DOACs) as prescribed. About 400 patients will either receive this extra support or usual care. The goal is to see if the education improves …

This study is testing whether a special home blood pressure monitor that can detect atrial fibrillation (AFib) helps diagnose the condition faster in older adults with high blood pressure. About 1,900 participants aged 60 and older will take daily blood pressure readings and answ…

This study tests whether smartwatches can detect atrial fibrillation (AF) in people who recently had a stroke. Participants already have an implanted heart monitor (the gold standard) and will also wear a smartwatch for 12 weeks. The goal is to see how well the smartwatch catches…

This study tests a new MRI contrast agent called Gadopiclenol to see if it provides clearer images of heart damage in people with atrial fibrillation (AF). Researchers will compare it to standard contrast agents in 50 AF patients. The goal is to improve diagnosis and guide treatm…

This study tests whether an artificial intelligence program can use a simple, single-lead handheld ECG device to find people with undiagnosed atrial fibrillation (AF), a common heart rhythm problem. About 200 adults aged 50-90 will use a device at home and complete surveys. The g…

This study is testing whether monthly 12-lead ECG screenings at family health centers can detect undiagnosed atrial fibrillation (AF) in adults aged 65 and older. Participants will have 12 monthly visits over a year, and if AF is found, they will be started on blood thinners to r…

This study tests whether smartphone sensors and AI can accurately detect atrial fibrillation (AF), a common heart rhythm disorder. Researchers will collect heart sounds, one-lead ECGs, and facial blood flow data from 209 adults with and without AF. The goal is to see if these sma…

This study tests a simpler deep-sedation method for people having a heart procedure called pulsed-field ablation to treat atrial fibrillation (an irregular heartbeat). The goal is to see if the new sedation approach is safe and makes patients more comfortable. About 40 adults wil…

This study tests a simple, non-invasive device that gently stimulates a nerve in the ear (tVNS) to see if it can improve cognitive function in people over 60 with atrial fibrillation. For 6 months, 60 participants will use the device daily after exercise. Researchers will measure…

This study tests whether a sticky disc called StatSeal helps people recover faster after a common heart procedure for atrial fibrillation. After the procedure, doctors must close the blood vessel in the leg to stop bleeding. Currently, they often use a stitch (figure-of-eight). T…

This study looks at a new way to analyze electrical signals in the heart to help doctors find exactly where to burn during atrial fibrillation treatment. Researchers will review data from 336 patients who had the procedure, comparing those who stayed free of AFib for a year with …

This study compares six different ECG patches that people wear for a week to monitor heart rhythms. Researchers want to see which patches give the clearest and most useful recordings. The study involves 150 adults aged 65 and older who already need heart monitoring as part of the…

This registry is collecting data from over 500 patients with atrial fibrillation who are treated with the FARAPULSE ablation system in routine care. The goal is to identify which pre-procedure, procedure, and follow-up steps work best for different types of patients. Researchers …

This study tests whether a special CT scan (CCTA) of the heart can predict if atrial fibrillation will come back after a standard ablation procedure. Researchers will scan patients before their first ablation and then follow them for a year. The goal is to see if heart structure …

This pilot study looks at whether a simple, non-invasive eye scan (OCT-A) can detect early signs of memory decline in people with atrial fibrillation, a common heart rhythm disorder. Researchers will compare retinal blood vessel patterns in 40 patients with and without mild cogni…

Over two million people in the UK have a chronic condition like diabetes or heart disease without knowing it. This study will use information from 4.5 million hospital patients to build a digital platform that spots those at risk. The goal is to help doctors diagnose these condit…

This study looks at whether a new computer algorithm can predict if atrial fibrillation (an irregular heartbeat) will come back after a common treatment called pulmonary vein isolation. Researchers will review medical records from 300 patients who had this procedure. The goal is …

This study watches 40 adults who need a leadless pacemaker to see if where the device sits inside the heart changes heart rhythm or pumping strength. Researchers will use CT scans and ECGs to check heart function and valve leakage. The goal is to find the best spot for the pacema…

This study observes 1,000 adults aged 65 and older with atrial fibrillation who take blood thinners. Researchers will check if the doses match official guidelines and how consistently patients take their medication. The goal is to identify unsafe practices and refer patients to h…

This study looks at two methods of giving the blood thinner heparin during a procedure called atrial fibrillation ablation. The goal is to see which method keeps the blood's clotting time in a safe range more often. Researchers reviewed records of 300 patients who had the procedu…

This study looks at whether a special training program can help family doctors use focused heart ultrasound (FoCUS) to accurately detect common heart conditions like heart failure and valve disease. About 500 patients will get both a family doctor's FoCUS and a cardiologist's ful…

This study looks at a possible side effect of a heart treatment called PFA for atrial fibrillation: injury to the phrenic nerve, which can paralyze part of the diaphragm and affect breathing. Patients get a special X-ray before and after the procedure to check diaphragm movement.…
