Key result
The overall prevalence of atrial fibrillation is less than 1%, but in people aged 80 years or older, the rate is approximately 7–14% in Western countries and 2–3% in Japan.
The prevalence of atrial fibrillation is increasing globally with population aging, highlighting the need for improved management strategies for this common arrhythmia.
AF burden rises with aging populations; leaves open region-specific prevention and management strategies.
Atrial fibrillation (AF) is the most common arrhythmia in persons of advanced age, and it is a potent risk factor for cardiogenic ischemic stroke. The overall prevalence of AF is less than 1%, but in people aged 80 years or older the rate is approximately 7–14% in Western countries and 2–3% in Japan. The number of people with AF has been increasing worldwide as the population has aged, and continued increases in the prevalence and incidence of AF are expected with the aging of society. It is predicted that 5–16 million in the United States and more than 1 million in Japan will be affected by 2050. Therefore, AF is one of important diseases that needs to be managed because it is a common disease in aged populations.

Kodani et al. (2012) conducted a review in Atrial fibrillation. The overall prevalence of atrial fibrillation is less than 1%, but in people aged 80 years or older, the rate is approximately 7–14% in Western countries and 2–3% in Japan.
