Why the study?
Does atrial fibrillation increase the incidence of embolization from the atria in patients with arteriosclerotic heart disease?
Does atrial fibrillation increase the incidence of embolization from the atria in patients with arteriosclerotic heart disease?
Atrial embolization is uncommon in arteriosclerotic heart disease, regardless of the presence of atrial fibrillation, which contrasts with the higher risk seen in rheumatic heart disease.

Embolization remains uncommon in arteriosclerotic heart disease regardless of atrial fibrillation; leaves open whether rhythm confers differential risk versus rheumatic disease.
One thousand autopsied cases were studied to determine the incidence of embolism from the atria in arteriosclerotic heart disease. In this study, it was found that 1 case of embolization occurred in a total of 52 patients with atrial fibrillation (2%), and 2 cases of embolization occurred in a total of 243 cases who were nonfibrillators (0.8%). Atrial embolization was uncommon in arteriosclerotic heart disease regardless of the prevailing atrial rhythm during life. This situation is contrasted with that present in rheumatic heart disease where atrial fibrillation is associated with a definitely increased risk of embolization.
