Popis: Objective: Previous studies have investigated the relationships between alcohol and ventricular structure, but few studies have evaluated the relation between alcohol consumption and the atrium size. This study aims to test the association between alcohol consumption and left atrium (LA) size in a general population. Methods: A population-based sample of 10 211 subjects aged ≥ 35 years and free from hypertension at baseline were followed from January 2012 to August 2013. Left atrial enlargement (LAE) was defined as the ratio of LA diameter to body surface area exceeding 2.4 cm/m2 in both genders. Independent factors for LAE were estimated by multiple logistic regression analyses. Results:The study included 10 211 participants (4 751 men and 5 460 women). Left atrium diameter / body surface area (LAD/BSA) was higher in the moderate and heavy alcohol consumption groups compared with the non-drinker group (non-drinker, 20.5+-0.03 cm/m2; moderate, 20.8+-0.09 cm/m2; and heavy, 20.6+-0.06 cm/m2; P
