Abstract
Objective: To assess left atrial function using Speckle- tracking echocardiography in patients with hypertension and metabolic syndrome. To explore the relationship between left atrial function and the ankle-brachial index (ABI) in the study population. Subjects and methods: This is a cross-sectional descriptive study conducted on 56 patients diagnosed with hypertension undergoing examination and treatment at the National Heart Institute - Bach Mai Hospital from 9/2023 to 9/2024. Results: The average age was 59,48 ± 11,66, predominantly female (66,07%). Left atrial function assessed by speckle tracking ultrasound showed significant impairment in conduction and contraction phases. Factors affecting left atrial function: Triglycerides, HDL-Cholesterol, Glomerular filtration rate, BMI, Heart rate, Age. Low ABI index was associated with decreased reservoir and contraction function of the left atrium, while it did not significantly affect the blood conduction ability of the left atrium.
