Title

A COMPAREMENTAL STUDY OF LEFT ATRIAL DIAMETER IN PATIENTS WITH ATRIAL FIBRILLATION WITH KNOWN AND UNKNOWN ETIOLOGY

English Abstract

Introduction: Cardiovascular disease is one of the most common diseases in the world today, especially in old ages. One important group of these diseases is cardiac arrhythmias. The most common chronic cardiac arrhythmia in general population is atrial fibrillation (AF). AF rhythm may be induced by multiple causes, but in some cases no cause can be detected. Objectives: Inthis study, we attempted to compare the left atrial diameter in patient with AF rhythm with known (group 1)and unknown (group 2) etiology. Materials & Methods: This study was done in prospective and descriptive-analytic and cross-sectional manner, and all of the patients with AF rhythm who entered in the study were evaluated from etiologic aspect with taking history,serial ECGs, echocardiography and checking serum thyroid hormones levels, and the collecteded data were inserted in special forms and then analyzed by statistical methods like SPSS software. Results: Totally, 135 patients with AF rhythm were studied. 51.1% of patients were female and 48.9% were male. The mean age of cases was 65 years and 63.3% of patients were over 60 years. In this study, the most common causes of AF rhythm were ischemic heart disease, hypertension, valvular heart disease, hyperthyroidism, respectively, and 13.3% of cases had AF with unknown etiology (lone AF). The mean left atrial diameter in all of the patients was 4.09 cm, while it was 4.1 cm and 3.7 cm in patients of group 1 and group 2, respectively. Conclusions: The prevalence of AF rhythm had no relation with gender in this study. 13.3% of cases had lone AF. The prevalence of AF had a strong relation with increasing of age.The mean left atrial diameter in patients with AF with known etiology was higher than patients with lone AF but the difference was not significant from statistical aspect.
