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.

Race impacts adverse outcomes in atrial fibrillation

Black individuals with atrial fibrillation have markedly higher rates of stroke, heart failure, coronary heart disease and mortality than their White counterparts, data from the Atherosclerosis Risk in Communities study show. [More]
NOACs match warfarin for atrial fibrillation

NOACs match warfarin for atrial fibrillation

Real-world study data from Denmark show that non-vitamin K antagonist oral anticoagulants are effective alternatives to warfarin in patients with non-valvular atrial fibrillation in a routine care setting. [More]
Cardiac surgery patients who received omega-3 supplementation experience reduced hospital stays

Cardiac surgery patients who received omega-3 supplementation experience reduced hospital stays

A new meta-analysis published in Clinical Nutrition found that cardiac surgery patients who received omega-3 polyunsaturated fatty acids (compared to placebo) in advance of surgery experienced reduced postoperative cardiac arrhythmias and significantly reduced the length of hospital stay by up to 2.4 days. The results are based on 11 RCT's with 1038 patients. [More]
AF patients at risk for stroke mostly treated with aspirin-only prescription instead of blood thinners

AF patients at risk for stroke mostly treated with aspirin-only prescription instead of blood thinners

Researchers at University of California San Diego School of Medicine and University of California, San Francisco School of Medicine report that more than 1 in 3 atrial fibrillation (AF) patients at intermediate to high risk for stroke are treated with aspirin alone, despite previous data showing this therapy to be inferior to blood thinners.

Apixaban effective in polypharmacy setting

The superiority of apixaban over warfarin in patients with atrial fibrillation is maintained in those taking multiple medications, shows further analysis of the ARISTOTLE trial. [More]

Worsening renal function linked to increased cardiovascular risk in AF

Patients with atrial fibrillation and declining renal function are at increased risk of subsequent stroke or systemic embolism, major bleeding and death, US researchers report. [More]
Watchman device for irregular heart rhythms may be preferable to standard blood thinning medications

Watchman device for irregular heart rhythms may be preferable to standard blood thinning medications

Penn researchers explore possibilities to improve outcomes in low flow AS patients treated with TAVR

Penn researchers explore possibilities to improve outcomes in low flow AS patients treated with TAVR

Aortic stenosis (AS), the narrowing of the aortic valve in the heart which causes restricted blood flow, is one of the most common and serious valve disease problems. For patients with one type of AS - low flow - transcatheter aortic valve replacement (TAVR), a minimally invasive procedure which corrects the damaged aortic valve, is often the best option for restoring the heart's normal pumping function.

Study evaluates effectiveness of robotic approach over manual ablation in treating heart arrhythmia

Study evaluates effectiveness of robotic approach over manual ablation in treating heart arrhythmia

Whether ablation of the highest-risk heart arrhythmia is best handled by a robot or the hands of an electrophysiologist should be answered by an international comparison of the two. [More]

Consensus paper on atrial cardiomyopathies could be important step forward for research, treatment

The first consensus paper on atrial cardiomyopathies is set to be published simultaneously in EP-Europace, HeartRhythm, and the Journal of Arrhythmia. The key contents are launched today at CARDIOSTIM - EHRA EUROPACE 2016. [More]

Air pollution becomes leading risk factor for stroke worldwide

Air pollution – including environmental and household air pollution - has emerged as a leading risk factor for stroke worldwide, associated with about a third of the global burden of stroke in 2013, according to a new study published in The Lancet Neurology journal. [More]

Women more likely to be hospitalised for acute ischaemic stroke than men, say researchers

A 15 year study in 1.1 million patients with atrial fibrillation has found that women are 23% more likely to be hospitalised for acute ischaemic stroke than men. The research was presented today at CARDIOSTIM - EHRA EUROPACE 2016 by Dr Ghanshyam Shantha, a cardiovascular disease fellow at the University of Iowa Hospitals and Clinics, Iowa City, Iowa, US.
