Atrial Fibrillation News and Research

RSS

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.

FDA panel votes 9-2 in favor of new blood thinner drug

Cardiovascular and Renal Drugs Advisory Committee recommends FDA approval of J&JPRD's rivaroxaban

Johnson & Johnson Pharmaceutical Research and Development, L.L.C. (J&JPRD) announced today that the U.S. Food and Drug Administration's (FDA) Cardiovascular and Renal Drugs Advisory Committee recommended approval of rivaroxaban, a novel, once-daily, oral anticoagulant, for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation.

FDA stalls the blood-thinner Xarelto’s approval citing inadequate evidence

The Food and Drug Administration (FDA) said in a staff report released today that “there is insufficient information about the drug to determine whether it is safe for use with its proposed labeling.” Their report questions its safety and effectiveness, saying a new study is needed.

Bristol Meyer Squibb’s new blood thinner drug for stroke prevention

Researchers find that an experimental anticlotting pill Eliquis is more effective than standard drug, warfarin, at preventing strokes in people with a heart condition that puts them at high risk of blood clots and stroke. The new drug also known as apixaban, cut the risk of stroke by 21% compared with warfarin in people with atrial fibrillation (AF). It lowered the risk of dying by 11%.

Dabigatran etexilate superior to warfarin for stroke prevention in AF patients

New data from two RE-LY trial sub-group analyses show that dabigatran etexilate provides consistent benefits in stroke in atrial fibrillation (AF) compared to well-controlled warfarin, irrespective of whether patients use antiplatelet or other concomitant therapies, such as the anti-arrhythmics amiodarone or verapamil.

AF AWARE campaign launches Atrial Fibrillation in Primary Care tool

The AF AWARE campaign today, at the European Society of Cardiology (ESC) Congress 2011 in Paris, announces the launch of the Atrial Fibrillation in Primary Care (AFIP) tool, developed to help primary care physicians (PCPs) with early diagnosis and optimal management of patients with atrial fibrillation.

One in three AF patients at high risk of stroke are not being prescribed VKA therapy

New data show that, worldwide, one in three patients with atrial fibrillation (AF) who are at high risk for stroke are not being prescribed anticoagulant therapy, particularly vitamin K antagonists (VKA) – medicines known to significantly lower stroke risk in these patients.

ELIQUIS better than warfarin in reduction of stroke, major bleeding, and mortality

Bristol-Myers Squibb Company and Pfizer Inc. today announced the main results of the Phase 3 clinical trial ARISTOTLE, which evaluated ELIQUIS compared to warfarin for the prevention of stroke or systemic embolism in 18,201 patients with atrial fibrillation and at least one risk factor for stroke.

Strong link between leisure-time physical activity and AF among men

A Norwegian survey carried out between 1974 and 2003 showed that there was a graded independent increase in the risk of AF with increasing levels of physical activity in a population-based study among men with ostensibly no other heart disease. In women the data were inconclusive.

Apixaban superior to warfarin in preventing stroke and systemic embolism

A large-scale trial finds that apixaban, a new anticoagulant drug, is superior to the standard drug warfarin for preventing stroke and systemic embolism in patients with atrial fibrillation.

Arrythmia drug may work in stroke prevention: Study

The latest research has revealed that a new drug for treating people with an irregular heartbeat has fewer side effects than the standard treatment and is just as good at cutting the risk of stroke. Rivaroxaban, which is easier for people to take, is as effective as warfarin at preventing blood clots and thus lowering the risk of stroke for patients with atrial fibrillation say researchers.

Group Health study finds higher dementia risk with atrial fibrillation

The most common kind of chronically irregular heartbeat, known as atrial fibrillation, is associated with a greater risk of dementia, including Alzheimer's disease. This discovery by scientists at Group Health Research Institute and their collaborators was published online in advance of print on August 1 in the Journal of the American Geriatrics Society.
