Atrial Fibrillation

A nurse describes his own bout with atrial fibrillation-the symptoms and his attempts to cardiovert to normal rhythm-from his hospital bed.

Overall it looks as though pharmacologic rate control is still the preferred therapy for new onset AF, but a new study identifies some interesting trends in the use of drugs for both rhythm and rate.

Atrial fibrillation and dementia have long been linked, partly because both tend to affect the elderly. But there may be a causal link as well related to management of anticoagulation.

The recent AFFORD trial suggests no clinical role for omega-3 fatty acids in preventing atrial fibrillation or in modulating disease markers.

A new study finds that iPhone-based technology deployed in local pharmacies can detect asymptomatic atrial fibrillation. iECG anyone?

Results of a recent study suggest the presence or absence of CMBs may help refine risk prognostication in patients with AF.

The cost vs the benefit of community screening for disease is often hotly debated. A new study suggests that detection and treatment of asymptomatic AF may be worth that effort.

Lone atrial fibrillation describes isolated episodes of AF that have been previously considered benign. A revised picture is emerging, according to a new study.

A very large observational study heightens concern around use of digoxin in the treatment of newly diagnosed atrial fibrillation, despite guideline recommendations.

A new study identifies obesity and inactivity as independent risk factors for atrial fibrillation in postmenopausal women. Exercise attenuated the risk in the study cohort.

A new dark spot on the forehead; overprescribing of benzodiazepines; alcohol and atrial fibrillation . . . can you answer the quiz questions on these topics?

A very large Swedish study and meta-analysis found a dose-response relationship between incident atrial fibrillation and alcohol, with an approximate 8% increase in risk for the arrhythmia per daily drink consumed.

High-sensitivity troponin T and N-terminal-pro-BNP were shown in 2 important studies to help predict risk of stroke and embolic events in patients with atrial fibrillation.

In a proof-of-principle study, German researchers evaluated an affordable, accessible, and cost-effective way to help diagnose atrial fibrillation after ischemic stroke, with promising results.

Put yourself to the test: This week’s quiz questions you about skin disease, diabetes, sarcoidosis, atrial flutter, and pain medications.

A recent study found the lower cost to be the result of fewer episodes of major bleeding in patients treated with apixaban.

Post hoc analysis of the ENGAGE AF-TIMI 48 study looked at safety and efficacy of a novel oral anticoagulant in distinct groups with paroxysmal, persistent, or permanent atrial fibrillation.

A new study finds that ablation for atrial flutter reduces hospital-based costs, symptoms, and risk of atrial fibrillation. For stroke risk? Continue anticoagulation.

. . . . And then there’s lipoprotein(a), a diagnostic puzzle that involves acute abdominal pain and a CT scan in a woman with a complicated medical history, and skin lesions that look like coins. 5 questions in all. . . .

A meta-analysis shows both IV and oral formulations pose a risk of arrhythmia, the former more so than the latter. But these are very effective drugs. What next?

Results from the CRYSTAL-AF study find that nearly one-third of patients who experience cryptogenic stroke may have undetected atrial fibrillation.

A recent white paper declares it time to abolish the ambiguous term. Given current knowledge of atrial fibrillation, the 60-year-old description serves only to confuse.

Men who engage in intensive workouts early in life may increase their risk for cardiac arrhythmias when they are older, a new study finds.

Aging baby boomers will more frequently appear in primary care offices with cardiovascular diseases that place them at high risk for both clotting and bleeding. Many will also have atrial fibrillation. Is there a sure-fire therapeutic formula for all?

In a clinical trial setting, performance of the new oral anticoagulant and the long-time gold standard was similar. In the real world, where adherence can be a problem, there is a risk/benefit ratio to consider.

Warfarin continued in the periprocedural period yielded lower rates of stroke, TIA, and minor bleeding than use of heparin to bridge catheter ablation surgery for AF.

A small study provides good evidence that radiofrequency ablation as first-line therapy has a lower failure rate vis a vis recurrence of AF when compared with antiarrhythmic therapy. But, there is more to this story.

According to a study published in the British Medical Journal, the risk of atrial fibrillation/atrial flutter is greater in NSAID-naive patients than in those with previous exposure.

Four updates to the guidelines are important for primary care physicians to review.

In clinical scenarios where warfarin is still the drug of choice for anticoagulation, it is still a challenge to achieve optimal time in therapeutic range. Is there promise in a new dosing paradigm?
