Atrial fibrillation causes hypercoagulability and thrombosis in the left atrium, rupture of blood clots, causing embolism, the most serious is cerebral embolism. Approximately 90% of cerebrovascular events in patients with atrial fibrillation without valvular disease originate in the left atrium. Atrial appendage occlusion reduces the risk of death from a stroke by 38%.1. Atrial fibrillation
Atrial fibrillation may be responsible for about 5% of strokes each year. In patients with heart failure and atrial fibrillation, the mortality rate increased by 34%. The incidence of atrial fibrillation increases with age, with an average incidence of AF about 0.1% per year in people under 40 years of age, but increasing to 1.5-2% in people over 80 years of age.
