An irregular heartbeat – atrial fibrillation – is a strong predictor of cognitive decline and the loss of independence in daily activities in older people at risk of cardiovascular disease, according to a study in CMAJ (Canadian Medical Association Journal). Researchers sought to understand whether there was an association between an irregular heartbeat and the loss of mental and physical functions in people at risk of cardiovascular disease. They looked at data from two...

An irregular heartbeat that you don't even feel but can be picked up by a pacemaker is associated with a significantly increased risk of stroke, says a new McMaster University study. The report, published in the New England Journal of Medicine today, says that of nearly 2,600 patients without a history of atrial fibrillation but with a recently implanted pacemaker, more than one-third had episodes when the heartbeat would become rapid and irregular for more than six minutes. In 85 per...

University of Adelaide research shows that obesity is directly linked to electrical abnormalities of the heart. University of Adelaide research has shown for the first time that obesity directly causes electrical abnormalities of the heart. Cardiologist and PhD candidate Dr Hany Abed says there is growing evidence that obesity changes the structure and size of the heart muscle and the way it works and contracts, as well as its electrical function. The latter leads to atrial fibrillation, the...

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. "Both atrial fibrillation and dementia increase with age," said...

Researchers at Brigham and Women's Hospital have found that among women who are mostly healthy, those diagnosed with atrial fibrillation have an increased risk of death when compared to women without atrial fibrillation Researchers at Brigham and Women's Hospital (BWH) have found that among women who are mostly healthy, those diagnosed with atrial fibrillation have an increased risk of death when compared to women without atrial fibrillation. These findings are published in the May 25, 2011...

Measuring oxidative stress may help doctors predict the risk of developing atrial fibrillation, the most common heart beat irregularity. Research from Emory University School of Medicine has identified a connection between oxidative stress and enlargement of the heart's left atrium, which leads to atrial fibrillation. The data is being presented on Monday, April 4, by Emory cardiology researcher Nima Ghasemzadeh, MD, at the American College of Cardiology meeting in New Orleans. Working with...

Study Highlights: -- More than half of atrial fibrillation (AF) cases in this study were linked to specific risk factors. -- High blood pressure was the strongest predictor of AF. -- Those with elevated risk factors were three times more likely to have AF. DALLAS, March 28, 2011 /PRNewswire-USNewswire/ -- Reducing cardiovascular risk factors like high blood pressure, smoking, diabetes and being overweight could potentially reduce more than half of all cases of atrial fibrillation,...

(Ivanhoe Newswire) "“ Stroke survivors with irregular heartbeats called atrial fibrillation may be at a higher risk of developing dementia than stroke survivors who don't have the heart condition, according to this study. Atrial fibrillation affects more than two million Americans, and it is more common as people age. About 15 percent of strokes occur in people with atrial fibrillation. The condition is characterized by the heart's two upper chambers not beating effectively, resulting...

Stroke patients who also suffer from an irregular heartbeat are at double the risk of developing dementia, according to a new study by the University of East Anglia (UEA). Published tomorrow in the journal Neurology, the findings show that stroke survivors with an irregular heartbeat "“ or atrial fibrillation - are 2.4 times more likely to develop dementia than stroke survivors without the heart condition. The researchers analysed 15 studies with more than 45,000 participants and an...

Atrial Fibrillation (AF) is the most common cardiac arrhythmia (abnormal heart rhythm). Its name comes from the fibrillating (i.e., quivering) of the heart muscles of the atria, instead of a coordinated contraction. The result is an irregular heartbeat, which may occur in episodes lasting from minutes to weeks, or it could occur all the time for years. Atrial fibrillation alone is not in itself generally life-threatening, but it may result in palpitations, fainting, chest pain, or congestive...
