Biomarker predicts success of Afib treatment

Johns Hopkins researchers report successful use of heart imaging to predict the benefit or futility of catheter ablation, an increasingly popular way to treat atrial fibrillation, a common heart rhythm disorder.

Atrial Fibrillation Treated With LAA Occlusion Reduces Thromboembolism Risk

Surgical left atrial appendage occlusion (S-LAAO) is associated with a lower risk for 3-year thromboembolism-related hospital readmission compared with no S-LAAO in older patients with atrial fibrillation (AF) undergoing cardiac surgery, according to findings from a retrospective study published in the Journal of the American Medical Association.

Migraine and risk of cardiovascular diseases: Danish population based matched cohort study

To examine the risks of myocardial infarction, stroke (ischaemic and haemorrhagic), peripheral artery disease, venous thromboembolism, atrial fibrillation or atrial flutter, and heart failure in patients with migraine and in a general population comparison cohort.

Migraines Linked to More Cardio Problems

Migraine is associated not just with increased risks of strokes and heart attacks, but also with blood clots and irregular heart rates, according to an observational study of over a half million people in Denmark.

Association Between Left Atrial Appendage Occlusion and Readmission for Thromboembolism Among Patients With Atrial Fibrillation Undergoing Concomitant Cardiac Surgery

In this retrospective cohort study of 10 524 Medicare recipients with atrial fibrillation undergoing cardiac surgery, surgical left atrial appendage occlusion, compared with no surgical left atrial appendage occlusion, was significantly associated with lower risk of readmission for thromboembolism at 3 years (unadjusted, 4.2% vs 6.2%; adjusted hazard ratio, 0.67).

Everyone has heart palpitations, but for some it can be serious

You might feel them as skipped heartbeats or unusually forceful beats. One friend describes her heart palpitations as a soft fluttering that starts in her chest, moves to her neck and sometimes makes her cough

Experts: Atrial fibrillation becoming epidemic among older patients

LITTLE ROCK (KATV) — There are at least 2.7 million Americans living with atrial fibrillation, or a-fib. It's an irregular heartbeat that can lead to blood clots, stroke, heart failure and other heart-related complications, according to the American Heart Association. It's a condition some experts call an epidemic.

Electromechanical vortex filaments during cardiac fibrillation

Self-organized dynamics of vortex-like rotating waves or scroll waves underlie complex spatial-temporal pattern formation in many excitable chemical and biological systems1–4. In the heart, filament-like phase singularities5,6 associated with three-dimensional scroll waves8 are considered to be the organizing centers of life-threatening cardiac arrhythmias7–13.

Heart researchers develop a new, promising imaging technique for cardiac arrhythmias

Every five minutes in Germany alone, a person dies of sudden cardiac arrest or fibrillation, the most common cause of death worldwide.

New procedure for stroke-prone patients at Munson

But new technology at Munson Medical Center is reducing the stroke risk for certain heart patients with atrial fibrillation. The Watchman device is delivered to the left atrium of the heart and seals off the appendage to prevent blood clots from forming. Munson Medical Center cardiac electrophysiologist Dr.
