Left atrial size and echocardiographic diastolic parameters as predictors of incident atrial fibrillation in older hospitalized patients.

ABSTRACT:

Background

The associations between left atrial (LA) size, echocardiographic diastolic parameter (E/A ratio), and incident atrial fibrillation (AF) in older inpatients remain underexplored.

Aims

This study aimed to evaluate the relationship between LA size, E/A ratio, and AF risk in older hospitalized patients.

Methods

Between January 2015 and May 2023, a total of 2,615 older inpatients (aged ≥ 65 years) were enrolled in this retrospective longitudinal study. Left atrial diameter (LAD) and E/A ratio were measured using transthoracic echocardiography.

Results

Over a median follow-up of 844 days (IQR: 331-1355 days), 209 patients (8.0%) experienced at least one incident of AF. After adjusting for covariates, large LA and high E/A ratio were significantly associat
