Successfully treating heart rhythm disorder improves long-term survival for cardiac surgery patients with atrial fibrillation A recent study conducted by Northwestern Medicine® researchers published in the Journal of Thoracic and Cardiovascular Surgery, reveals that patients with an abnormal heart rhythm known as atrial fibrillation (A-fib) who are undergoing cardiac surgery, have a lower long-term survival rate compared with patients who are in sinus rhythm, which is the normal beating...

Procedure may stop 'flight or fight' stress response impacting heart What do sweaty palms and abnormal heart rhythms have in common? Both can be initiated by the nervous system during adrenaline-driven "flight or fight" stress reaction when the body senses danger. Governed by the sympathetic nervous system, an abnormal "flight or fight" stress response which causes excessive sweaty palms (called hyperhidrosis) may also contribute to problems like dangerous irregular heart rhythms from...

Many patients are looking for a drug-free lifestyle Results presented today from the Atrial Fibrillation Ablation Pilot Study show that almost 40% of patients undergoing a catheter ablation for atrial fibrillation have no underlying disease associated with the arrhythmia, and precipitating factors are rare. The survey, which is a pilot survey from the ESC's EurObservational registry program, also confirmed that symptoms are present in 86% of patients but vary considerably; symptoms include...

Research: Non-steroidal anti-inflammatory drug use and risk of atrial fibrillation or flutter: Population-based case-control studyCommonly used painkillers to treat inflammation are linked to an increased risk of irregular heart rhythm (known as atrial fibrillation or flutter), concludes a study published on bmj.com today.The drugs include non-selective non-steroidal anti-inflammatory drugs (NSAIDS) as well as new generation anti-inflammatory drugs, known as selective COX-2 inhibitors.These...

University of British Columbia researchers "“ using an innovative, atom-by-atom substitution method "“ have uncovered the mechanism by which a particular class of drugs controls irregular heartbeats.The findings, published today in the online journal Nature Communications, shed light on why certain anti-arrhythmic drugs (AADs) have dramatically different effects on the heart's behavior compared to others, and why the same drug can be beneficial in some instances and fatal in others. The...

Lead investigator available at HeartRhythm 2011 to discuss data that underscore the growing impact of AFib on US health care costs and resourcesTwo studies to be presented this week address the often-overlooked costs associated with atrial fibrillation (AFib), the most common form of cardiac arrhythmia. Each study evaluates these costs and updates a growing body of evidence suggesting that the true costs of AFib are complex and may not yet be fully understood. The patient populations studied...

(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 in an...
