Atrial Fibrillation News and Research RSS Feed - Atrial Fibrillation News and Research

Atrial fibrillation (AF) is the most common arrhythmia. An arrhythmia is a problem with the speed or rhythm of the heartbeat. A disorder in the heart’s electrical system causes AF and other types of arrhythmia. AF occurs when rapid, disorganized electrical signals in the heart’s two upper chambers, called the atria, cause them to contract very fast and irregularly (this is called fibrillation). As a result, blood pools in the atria and isn’t pumped completely into the heart’s two lower chambers, called the ventricles. When this happens, the heart’s upper and lower chambers don’t work together as they should. Often, people who have AF may not even feel symptoms. However, even when not noticed, AF can lead to an increased risk of stroke. In many patients, particularly when the rhythm is extremely rapid, AF can cause chest pain, heart attack, or heart failure. AF may occur rarely or every now and then, or it may become a persistent or permanent heart rhythm lasting for years.

Atrial fibrillation patients treated with anticoagulant drug have higher risk of developing dementia

Atrial fibrillation patients treated with anticoagulant drug have higher risk of developing dementia

Atrial fibrillation patients who use the drug, warfarin, to prevent harmful blood clots from forming in their hearts to lower risk of stroke are at higher risk of developing dementia than patients who use warfarin for non-atrial fibrillation conditions, according to a new study from the Intermountain Medical Center Heart Institute.

New treatment strategy effective in preventing bleeding in AF patients who underwent PCI, study shows

A new study led by clinician-researchers at Beth Israel Deaconess Medical Center testing the safety and effectiveness of anticoagulant strategies for patients with atrial fibrillation who undergo stenting procedures has shown that therapies combining the anticoagulant drug rivaroxaban with either single or dual anti-platelet therapy were more effective in preventing bleeding complications than the current standard of care.
