It is our hypotheses that 1) readily available ED data can be utilized in an AF clinical prediction rule to identify those patients at low or high risk for adverse outcomes; 2) Assigned risk can be utilized to drive physician decision-making by identifying patients who do not require hospital admission (low risk) and patients needing hospitalization (high risk); and 3) a facile version of the AFPR will be easily incorporated into standard ED patient management systems and assist physicians with risk stratification of patients presenting with AF.
AF: Impact on Present and Future National Health Over 2 million people in the United States have AF, the most common sustained arrhythmia.1 That number of patients is expected to increase to 5.6 million by 2050.1 AF is associated with a 4-5 fold increase in the risk of stroke, 3-fold increase in the risk of heart failure and 1.5-1.9 increased risk of death.2-6 The prevalence of AF increases as individuals age; 5.9% of those over 65 years of age and 9% of those over 80 years are diagnosed with the arrhythmia.25 The lifetime risk for development of AF is estimated to be 1 in 4 for men and women forty years of age and older.26 The proper management of patients with AF is critical due to the well-documented association with heart failure and stroke.2-6, 11, 27.
The number of ED visits for complaints related to AF increased by 88% between 1993 and 2003 and now account for approximately 1% percent of all ED visits in the United States.7, 24 More than 65% of these AF visits result in hospital admission and over $6.65 billion in expenditures, including $3.88 billion for hospitalizations, $1.53 billion for outpatient treatment and nearly $240 million for prescription drugs.8, 24 Patients with a primary admission diagnosis of AF had a mean length of stay and hospital charge of 4 days and $7000 in 1999.28 Over the past 20 years, the admission rate for AF has increased by 66%.29-31 The combination of increasing AF prevalence, unnecessarily high admission rate and ED crowding is likely to severely burden our healthcare system.

Comparison of Effectiveness of Ranolazine Plus Metoprolol Combination vs. FlecainidE pluS Metoprolol Combination in ATrial Fibrillation Recurrences FOllowing PhaRmacological or Electrical CardioverSion of AtRial Fibrillation
Atrial fibrillation (AF) is the most common arrhythmia in clinical practice with a prevalence reaching 5% in patients older than 65 years and an incidence that increases progressively with...
This is a sigle-center, prospective study to evaluate the role of D-Dimer testing in patients with atrial fibrillation receiving Dabigatran or warfarin anticoagulation therapy.
The purpose of this study is to determine if preforming a posterior left pericardiotomy prevents atrial fibrillation after cardiac surgery.
The objective of this registry is the characterization of patients with atrial fibrillation (AF) with confirmed valvular heart disease (VHD) who are prescribed edoxaban in a real-life clin...
ACS are a potent risk factor for AF, with new onset AF occurring in up to 1 in every 5 patients hospitalized with an ACS. Despite its relatively frequent occurrence and the many etiologic...
Catheter ablation for rhythm control is recommended in specific patient populations with paroxysmal, persistent, or long-standing persistent atrial fibrillation. Pulmonary vein isolation is the corner...
Deficiency of testosterone was associated with the susceptibility of atrial fibrillation. Angiotensin-II receptor antagonists were shown to reduce atrial fibrillation by improving atrial electrical re...
The aim of this study was to evaluate a spatial correlation between active atrial fibrillation (AF) drivers measured by ECGI and complex fractionated atrial electrograms (CFAEs) in patients with persi...
Recently, the analysis of the spatio-temporal behavior of atrial fibrillation activation patterns has been widely investigated with the aim to better understand the arrhythmia implications on the hear...
Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.
A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)
Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.
A THROMBIN inhibitor which acts by binding and blocking thrombogenic activity and the prevention of thrombus formation. It is used to reduce the risk of stroke and systemic EMBOLISM in patients with nonvalvular atrial fibrillation.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
