ATRIAL FIBRILLATION

This study tested whether checking blood thinning levels every week with a simple finger-prick device is better than the usual monthly blood draw for elderly nursing home residents. The goal was to keep their blood thinner levels in a safe range and reduce the risk of dangerous c…

This small pilot study aimed to see if a custom oral appliance (MyTAP with mouth shield) could reduce episodes of atrial fibrillation, a type of irregular heartbeat. Only 3 people participated before the study was stopped early. The approach was to use the device to possibly affe…

This small pilot study looked at two ways to manage atrial fibrillation (an irregular heartbeat) in people with a type of heart failure where the heart pumps normally but is stiff. The study compared a procedure called pulmonary vein isolation (ablation) to standard medication. T…

This study tested whether a single high dose (2000 mg) of oral amiodarone can safely and quickly restore normal heart rhythm in people with acute atrial fibrillation. It included both hospital inpatients and outpatients, but was terminated early after enrolling only 3 participant…

This study looked at a medical device that uses extreme cold to treat atrial fibrillation (AFib), a condition where the heart beats irregularly. The goal was to see if the freezing procedure safely prevents AFib from coming back for a year. The study enrolled 91 people with diffe…

This study looked at whether using a positive airway pressure (PAP) machine at night can reduce the return of atrial fibrillation (an irregular heartbeat) in people who also have obstructive sleep apnea. The study planned to include 129 adults with both conditions who were alread…

This study looked at whether the drug dronedarone can prevent atrial fibrillation (AFib) from coming back after a heart ablation procedure. About 22 adults with AFib were randomly assigned to take either dronedarone or a placebo after their ablation. The goal was to see if droned…

This study looked at using a device called WATCHMAN FLX to close a small pouch in the heart (left atrial appendage) in people with atrial fibrillation who have had serious stomach or intestinal bleeding. The goal was to see if this device could lower the risk of stroke and reduce…

This study compared using two quick electric shocks versus the usual single shock to try to restore a normal heart rhythm in people with atrial fibrillation who have factors that make a single shock less likely to work, such as obesity or lung disease. Only 5 people took part bef…

This study aimed to understand why people with certain genetic changes (TTN variants) might be at higher risk for dangerous heart rhythms like ventricular tachycardia. Researchers planned to use special heart mapping during a routine procedure for atrial fibrillation to look for …

This study looked at a common heart rhythm problem called atrial fibrillation (AF). The goal was to find better ways to predict which patients would benefit most from a procedure called ablation, which creates scar tissue in the heart to stop abnormal signals. Researchers planned…
