Atrial Fibrillation News

A large new study has found that most people can enjoy their coffee or diet cola free from heart worries -- caffeine doesn't seem to increase most people's risk of arrhythmias.

A new report finds athletes have a much higher risk of atrial fibrillation than non-athletes, and younger athletes have a higher risk than older athletes.

Greater public awareness is needed as well as further studies to confirm the results, including differences in susceptibility among devices, the authors say.

After a mini-stroke, doctors inserted a chip to monitor heartbeat, detect irregular heart rhythms, and help adjust medication to avoid another stroke.

Even one drink of alcohol can increase the risk of heart rhythm problems in people with irregular heartbeat.

A simple surgery may help lower the risk for strokes by more than a third in patients with atrial fibrillation,

A new study suggests that prescription versions of fish oil may raise the risk of a common heart rhythm disorder.

A-fib, also known as atrial fibrillation, affects more than 33 million people worldwide and is the most common type of abnormal heart rhythm.

A-fib patients who underwent ablation were half as likely to have an arrhythmia episode in the following year compared to patients on medication. And they were 61% less likely to have an episode that caused symptoms.

Millions of people take a fish oil or vitamin D supplement in hopes of warding off a host of ills. But a new study finds the nutrients won't shield against the common and potential heart rhythm disorder known as atrial fibrillation.

Previous studies have shown that AF is associated with an increased risk of dementia. This one assessed whether catheter ablation and medications for AF reduced that risk.

A necklace outfitted with a high-tech pendant may be able to screen for signs of an abnormal heart rhythm condition known as atrial fibrillation.

From weight loss to physical activity, lifestyle changes are effective, yet underused strategies to manage atrial fibrillation.

Be careful of burnout -- especially after a new study finds it can raise your risk for the dangerous irregular heartbeat known as atrial fibrillation.

When they compared the teetotalers to a similar group of people with a-fib who continued drinking, the investigators found that those who abstained from alcohol delayed their next a-fib episode and reduced the overall time spent in a-fib.

Millions of Americans have the potentially dangerous irregular heartbeat known as atrial fibrillation.

New research finds that a person's risk of atrial fibrillation (a-fib) increases by about 3% for every inch over the average height of 5-foot-7.

The strongest risk factor for a-fib was the number of times per week a person drank. The greatest risk was seen in those who drank every day, followed by drinking twice or once a week.

Researchers found that adults who grew up with smokers were more likely to develop atrial fibrillation, versus those with nonsmoking parents.

This irregular rhythm, called ventricular tachycardia (VT), occurs when the heart's lower chambers start to beat uncontrollably fast. Once it starts, it can kill within minutes.

A-fib is a common heart rhythm disorder sometimes triggered by stress and negative emotions. Beta blockers are drugs that block the effects of adrenaline and related substances.

The study improves understanding of how this wearable technology and app works in the real-world setting and how well the technology can detect long periods of a-fib, said a study co-leader.

Study subjects who got ablation -- where a catheter is used to tweak the heart muscle cells responsible for the arrhythmia -- also seemed to have less shortness of breath, less fatigue and all-around better quality of life five years later, with those who got drug therapy alone.

The newer drugs are called non-vitamin K oral anticoagulants (NOACs). Examples include dabigatran (Pradaxa), rivaroxaban (Xarelto) and apixaban (Eliquis).

People with the highest levels of salt in their diet had a higher rate of atrial fibrillation than those with the lowest salt intake in a new study.
