Compared with warfarin, low-dose new anticoagulant regimens showed similar overall reductions in stroke or systemic embolic events and a more favorable bleeding profile, but significantly more ischemic strokes.
The predictive value of this scoring system was evaluated in 90,490 elderly patients with nonvalvular AF who were taking warfarin therapy.Transcranial measurement of cerebral microembolic signals during pulmonary vein isolation: a comparison of two ablation techniques.The American Heart Association explains the treatment of AFib and prevention of atrial fibrillation.
In some patients, atrial fibrillation (AF) appears to be triggered by electrically active pulmonary vein foci.Mortality and rate of stroke or embolism in atrial fibrillation during long-term follow-up in the Embolism in Left Atrial Thrombi (ELAT) Study.Classification scheme for patients with atrial fibrillation (AF).
The cornerstones of atrial fibrillation (AF) management are rate control and anticoagulation.Effects of CYP2C19 genotype on outcomes of clopidogrel treatment.New Alternatives to Coumadin (warfarin) to Reduce the Risk of Stroke in the Treatment of Atrial Fibrillation Provide Doctors and Their Patients with More Options.
Stunning of the atria and stasis can occur after cardioversion, and this can lead to thrombus formation even though the patient is in sinus rhythm.Rivaroxaban versus warfarin in nonvalvular atrial fibrillation.In general, patients who develop AF only postoperatively do not need anticoagulation.According to the investigators, the increased mortality risk was not associated with drug adherence, concomitant treatment, comorbid cardiovascular disorders, or renal function.The goal of antiarrhythmic drug therapy is to reduce the duration and frequency of atrial fibrillation episodes, thus improving patient quality of life and symptoms.The Elderly on Primary-Prevention Statins: No Survival Gains in ALLHAT-LLT.Regardless, clinicians need to reevaluate their management strategies frequently, as AF burden and comorbidities increase with time.
It is a reasonable initial strategy for rhythm control prior to using antiarrhythmic drug therapy for patients with recurrent symptomatic paroxysmal AF (class IIa, LOE: B).As AF contributes to pathologic atrial and ventricular remodeling, restoration of sinus rhythm can slow or, in some cases, reverse atrial dilatation and left ventricular dysfunction.Extreme care must be taken in patients with preexcitation syndrome and AF.Novel genetic markers improve measures of atrial fibrillation risk prediction.
The irregular heartbeat known as atrial fibrillation is one of the toughest heart conditions to treat.Therefore, RFA is generally considered only if antiarrhythmic drugs fail in patients with persistent AF who remain severely symptomatic despite adequate ventricular rate control.Surgical ablation of AF is also an option for patients with AF undergoing other cardiac surgery and for those patients in whom pharmacologic and catheter-based procedures are ineffective or contraindicated.Bristol-Myers Squibb Pulls One Lot of Apixaban Over Tablet Mix-up.Many clinicians believe, however, that an attempt at a rhythm-control strategy should be made in most patients.
