Untreated atrial fibrillation carries an approximately 3 to 5% annual risk of ischemic stroke. Long-term oral anticoagulation therapy decreases this risk to 1.7% with warfarin and to 1.5% with ...

The incidence of atrial fibrillation approximately doubles with each decade of adult life and ranges from 2 or 3 new cases per 1000 population per year between the ages of 55 and 64 years to 35 new ...

Atrial fibrillation, also called AF or AFib, is a quivery, fluttery heartbeat. You might also hear the doctor call it arrhythmia. It means your heart’s normal rhythm is out of whack. Because your ...

The American College of Cardiology (ACC), American Heart Association, and the European Society of Cardiology define atrial fibrillation (AF) as a supraventricular tachyarrhythmia characterized by ...

An analysis of two large cohort studies finds that carriers of disease-causing variants within genes for three ...

Atrial fibrillation occurs and maintains itself in the context of a morphologically and functionally altered atrial substrate that can be induced by stressors such as underlying diseases (cardiac or ...

Management of AF from a rate control or rhythm control perspective has been studied via a meta-analysis of 5 randomized trials. 7 Rate control in combination with anticoagulation as front-line ...

More people have atrial fibrillation (AFib) than any other kind of irregular heartbeat. And the numbers are only expected to go up as people live longer with heart conditions that go along with it.

BACKGROUND: Premature atrial contractions (PACs) are independently associated with atrial fibrillation, stroke, and heart failure, yet no pharmacological therapy is approved for PAC suppression.

Atrial fibrillation occurs when cardiac electrical impulses become disordered, leading to a rapid and irregular heartbeat. Lip and colleagues discuss the mechanisms that underlie this common ...
