Overview
Atrial fibrillation is the most common arrhythmia found in clinical practice. It accounts for 1/3 of hospital admissions for cardiac rhythm disturbances, and the rate of admissions for AF has risen in recent years.
Epidemiology and Demographics
Incidence
- Researches have shown that the incidence of AF is approximately less than 0.1% per year in those under 40 years of age. On the other hand incidence rate increases to greater than 1.5% per year in women over 80 age and greater than 2% per year in men over 80 years of age. [1]
- Based on another study the incidence of atrial fibrillation among the US Medicare beneficiaries older than 65 years old has been reported 28.3 per 1,000 person annually.[2][3]
- Other studies demonstrated on European population released the following information regard the incidence of atrial fibrillation:[3][4][5]
- The incidence of atrial fibrillation has been estimated as 0.23 per 1,000 person/years in Iceland.
- The incidence of atrial fibrillation has been estimated as 0.41 per 1,000 person/years in Germany.
- The incidence of atrial fibrillation has been estimated as 0.9 per 1,000 person/years in Scotland.
Prevalence
- The prevalence in the general population is 0.4%.[6]
- The prevalence of atrial fibrillation has been increased during the last decades, due to various causes such as improved diagnostic tools, increased in age average in some populations and higher rate of successful treatment in cardiac patients.[3]
- Prevalence of atrial fibrillation has been estimated to be even more, since many cases of atrial fibrillation remain asymptomatic for a long time.[7]
- Approximately 2.2 million individuals in the United States and 4.5 million in the European Union have AF.[1][8]
Case-fatality rate/Mortality rate
- Atrial fibrillation is associated with a 1.5 to 1.9 fold increase in the risk of death.[1]
- The mortality rate of patients with atrial fibrillation is nearly double that of patients with normal sinus rhythm. This increase is due not only to atrial fibrillation alone but also due to the severity of possible underlying diseases, and is often due to thromboembolic events.[1]
- The administration of drugs aimed at rate control alone offers no survival advantage over the use of rate control along with anticoagulation as demonstrated in the AFFIRM trial.[9]
- The following table is a summary regard the increased mortality rate after atrial fibrillation development:[3][2]
| Mortality rate within 30 days of AF development | 10.8 % |
|---|---|
| Mortality rate in first year of AF development | 24.7% |
| Mortality rate within 3 first years of AF development | 42% |
Age
- The incidence of atrial fibrillation increases with age.[10][11]
- The prevalence of patients with atrial fibrillation in individuals over the age of 80 is about 10-17%. While only 3.7%–4.2% of patients aged 60–70 year have atrial fibrillation.[3]
- Patients with atrial fibrillation have a median age of 75 years.
- The proportion of patients with atrial fibrillation who are between 65 and 85 years of age is 70%.[12]
Race
- Prevalence of atrial fibrillation has been reported to be higher among Caucasians.
- Important genetic determinants may play a role since the age-adjusted risk of developing atrial fibrillation among African-Americans is less than half that in Caucasians.[13][14] [15]
Gender
- Atrial fibrillation is more common in males compared to females.[3]
- The male to female ratio has been reported as 1.2:1 in atrial fibrillation patients.
- There are more elderly women with atrial fibrillation, compared to men which is due to longer life among female patients.[15][16]
Region
The following table is a summary of how rate of atrial fibrillation differs among various regions: [3]
| Regions | Prevalence |
|---|---|
| Italy | 1.9 % |
| England | 1.9 % |
| Iceland | 1.9 % |
| Germany | 2.3 % |
| Sweden | 2.9% |
Developed Countries
In developed countries, the number of patients with atrial fibrillation is likely to increase during the next 50 years, due to the growing proportion of elderly individuals.[17]
Developing Countries
- Prevalence of atrial fibrillation in developing countries has estimated as 0.4 % in female and 0.6% in male populations.[3]
