==Overview==
[[Incidence]] of [[atrial fibrillation]] 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 [[female|women]] over 80 age and greater than 2% per year in [[male|men]] over 80 years of age. The [[atrial fibrillation]] [[prevalence]] in the general population is 0.4%. [[Prevalence]] of [[atrial fibrillation]] has been estimated to be even more, since many cases of [[atrial fibrillation]] remain [[symptom|asymptomatic]] for a long time. [[Atrial fibrillation]] is associated with a 1.5 to 1.9 fold increase in the risk of death. The [[incidence]] of [[atrial fibrillation]] increases with [[Ageing|age]] ([[median]] age of 75 years). [[Prevalence]] of [[atrial fibrillation]] has been reported to be higher among Caucasians (European ancestry) and it is more common in [[males]] compared to [[females]].

Overview

Incidence of atrial fibrillation 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. The atrial fibrillation prevalence in the general population is 0.4%. Prevalence of atrial fibrillation has been estimated to be even more, since many cases of atrial fibrillation remain asymptomatic for a long time. Atrial fibrillation is associated with a 1.5 to 1.9 fold increase in the risk of death. The incidence of atrial fibrillation increases with age (median age of 75 years). Prevalence of atrial fibrillation has been reported to be higher among Caucasians (European ancestry) and it is more common in males compared to females.

Epidemiology and Demographics

Prevalence

Case-fatality rate/Mortality rate


Mortality rate within 30 days of atrial fibrillation development 10.8 %
Mortality rate in first year of atrial fibrillation development 24.7%
Mortality rate within 3 first years of atrial fibrillation development 42%


  • A study done on Swedish population with 24 years follow up demonstrated the mortality rate is specifically higher within the first 4 months of diagnosis (67%).[10]

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.[21]
