Left Atrial Enlargement: A Crucial Indicator for Identifying Atrial Fibrillation in Patients With Hypertension

Based on the data of inpatients with hypertension and a cross-sectional study with a large sample size, this study aims to find the early warning value of the left anteroposterior atrial diameter for the possible occurrence of atrial fibrillation in patients with hypertension, and compare the advantages and disadvantages of the above two methods for the early warning of the risk of atrial fibrillation in patients with hypertension, so as to achieve the purpose of early identification of high-risk groups that may develop atrial fibrillation.
