Abstract

To compare the features of stroke associated with nonvalvular and valvular atrial fibri!lation, we carried out a retrospective study on cerebral infarcts in 27 patients with nonvalvular atrial fibrillation (AF) and in 33 patients with valvular AF.Iwe analyzed the clinical courses, the underlying heart diseases, and the features of echocardiography and brain cornputed tomograpy, Thefollowing results were obtained; 1) Most strokes in nonvalvular AF occurred after 7th decade and the age of stroke onset in nonvalvular group was younger than that of nonvalvular group(p<.05).; 2) Echocardiographic studiesshowed that the left atriurn of the heart in the nonvalvular AF group was srnaller in size than the valvular group and that the left atrial thrombi were not detectable on conventional echoardiograrn in the nonvalvular irouP.: 3) Both groups showed sirnilar distribution in the sites, number, and nature of the brain lesions.; 4) Stroke recurred with sirnilar frequency in both groups and rnost of them occurred during the first year of the initial stroke."
