Recent-onset atrial fibrillation and flutter are the most common arrhythmias managed in the emergency department (ED). We evaluate the management and 30-day outcomes for recent-onset atrial fibrillation and flutter patients in Canadian EDs, where cardioversion is commonly practiced. We conducted a prospective cohort study in 6 academic hospital EDs and enrolled patients who had atrial fibrillation and flutter onset within 48 hours. Patients were followed for 30 days by health records review and telephone. Adverse events included death, stroke, acute coronary syndrome, heart failure, subsequent admission, or ED electrocardioversion. We enrolled 1,091 patients with mean age 63.9 years, atrial fibrillation 84.7%, atrial flutter 15.3%, hospital admission 9.0%, and converted to sinus rhythm 80.1%. Although 10.5% of recent-onset atrial fibrillation and flutter patients had adverse events within 30 days, there were no related deaths and 1 stroke (0.1%). Adjusted odds ratios for factors ass...

The incidence of diagnosed atrial fibrillation is increasing in the USA, England, Wales, Scotland and Denmark, and the mortality rate in patients with diagnosed atrial fibrillation has been reported to be declining in Scotland and Denmark. We undertook this study to examine recent trends in incidence and mortality in subjects with a hospital diagnosis of atrial fibrillation or flutter in Denmark from 1980 to 1999 by sex, 10-year age group and conditions of comorbidity. We identified all individuals, aged 40-89 years, with an incident hospital diagnosis of atrial fibrillation or flutter in the Danish National Registry of Patients, and subjects were followed in the Danish Civil Registration System. We used multivariate Cox proportional hazard models to estimate trends in mortality. Atrial fibrillation or flutter was diagnosed in 131,728 subjects (68,660 men and 63,068 women), and the incidence of a hospital diagnosis of atrial fibrillation or flutter more than doubled during the study period. The hazard ratios for mortality adjusted for 10-year age group, conditions of comorbidity and mortality trend in the Danish population in the last 5-year period compared to the first 5-year period were 0.80 (95% confidence interval 0.78-0.82) in men, and 0.82 (95% confidence interval 0.80-0.84) in women. The incidence of a hospital diagnosis of atrial fibrillation or flutter more than doubled, and the 10-year age group- and comorbidity- and general population-adjusted mortality decreased, equally, from the first to the last 5-year period by 20% in men and 18% in women.

Background— Atrial fibrillation (AF) is the most common sustained arrhythmia; however, little is known about patients in a primary care setting from high-, middle-, and low-income countries. Methods and Results— This prospective registry enrolled patients presenting to an emergency department with AF at 164 sites in 46 countries representing all inhabited continents. Patient characteristics were compared among 9 major geographic regions. Between September 2008 and April 2011, 15 400 patients were enrolled. The average age was 65.9, standard deviation 14.8 years, ranging from 57.2, standard deviation 18.8 years in Africa, to 70.1, standard deviation 13.4 years in North America, P <0.001. Hypertension was globally the most common risk factor for AF, ranging in prevalence from 41.6% in India to 80.7% in Eastern Europe, P <0.001. Rheumatic heart disease was present in only 2.2% of North American patients, in comparison with 21.5% in Africa and 31.5% in India, P <0.001. The use ...
Atrial Fibrillation:: Public Health Implications
American journal of preventive …, 2005
Background: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in the United States, affecting 2.3 million Americans. AF is associated with significant morbidity, mortality, and poor quality of life. AF and its treatments result in high healthcare resource use and costs.
Atrial fibrillation and flutter outcomes and risk determination (AFFORD): Design and rationale
Journal of Cardiology, 2011
Background-Atrial fibrillation (AF) is the most common sustained arrhythmia affecting over 700,000 individuals in Japan and 2.2 million in the USA. The proper management of patients with AF is critical due to the well-documented association with heart failure and stroke. A strategy to better define the emergency department (ED) management, admission decisions, and spectrum of risk from low to high is needed.
Epidemiology and management of new-onset atrial fibrillation
The American journal of managed care, 2004
Atrial fibrillation (AF) is a common acute or chronic cardiac disorder that can result in significant morbidity and mortality. Its incidence in the United States is increasing. Projections suggest that more than 5.6 million Americans (50% of whom will be > or =80 years of age) will have AF by 2050. The American College of Cardiology, American Heart Association, and the European Society of Cardiology define AF as a supraventricular tachyarrhythmia characterized by uncoordinated atrial activation with consequent deterioration of atrial mechanical function. On an electrocardiogram, AF is characterized by the replacement of P waves by rapid oscillations or fibrillatory waves that vary in size, shape, and timing. Evidence suggests that histological changes exist in the atria of patients with AF, however, it is not known if these changes are a cause or a consequence of AF. Although the fundamental mechanism underlying the disorder is not known, clinical identifying factors are associat...

"STUDY OBJECTIVE: Atrial fibrillation is the most common dysrhythmia observed in the emergency department (ED), yet there is little research describing long-term outcomes after ED management. Our objective is to describe ED treatment approach, conversion success rates, ED adverse events, and 30-day and 1-year outcomes for a cohort of ED patients with atrial fibrillation and no acute underlying medical cause. METHODS: This retrospective cohort study used a database from 2 urban EDs to identify consecutive patients with an ED discharge diagnosis of atrial fibrillation from April 1, 2006, to March 31, 2010. Comorbidities, rhythms, management, and immediate outcomes were obtained by manual chart review, and patients with an acute underlying medical condition were excluded by predefined criteria. Patients were stratified into 5 groups according to ED management: electrocardioversion, chemical cardioversion, spontaneous cardioversion, rate control only, and no arrhythmia-specific treatment. To identify deaths, strokes, and ED revisits within 1 year, each patient's unique provincial health number was linked to the provincial vital statistics registry and the regional ED database. Primary outcome was the number of patients having either stroke or death of any cause at 30 days, stratified by treatment group. RESULTS: Of 927 consecutive eligible patients, 121 (13.1%) converted to sinus rhythm before ED intervention, 357 (38.5%) received ED rhythm control, and 449 (48.4%) did not receive rhythm control. Overall, 142 of 927 patients (15.3%) were admitted to the hospital at the index ED visit. At 30 days, 2 patients had a stroke and 5 died (combined outcome rate 0.8%; 95% confidence interval 0.3% to 1.6%). All 7 of these patients were admitted at the index ED visit. CONCLUSION: In this large cohort of ED patients with atrial fibrillation and no acute underlying medical cause, the 30-day rate for stroke or death was less than 1%. Nearly 85% of patients-regardless of treatment approach or conversion to sinus rhythm-were discharged at the index ED visit, and none of these patients had a stroke or died at 30 days."
