| Popis: | Aim. To study the relationship between the amount of epicardial left atrial fat and left atrial mechanical dispersion (LAMD) in hypertensive patients with persistent atrial fibrillation (AF) and without cardiac arrhythmias.Material and methods. The main group included 100 hypertensive patients with persistent AF, who underwent transesophageal echo cardiography (TEE) before the elective cardioversion, and transthoracic echocardiography (TTE) after cardioversion and disappearance of atrial stunning. The control group included 24 hypertensive patients without cardiac arrhythmias, who underwent TEE for other indication. The thickness of atrial septum and left lateral ridge was measured by TEE. The average thickness of these structures was designated as left atrial fat. The time to peak of longitudinal myocardial strain in 6 left atrium segments was determined by speckle-tracking echocardiography. LAMD was calculated as a percentage of the standard deviation of the obtained values to cardiac cycle duration.Results. The median left atrial fat thickness in the main and control groups was 8,03 [6,78; 8,95] and 5,23 [4,48; 5,80] mm (p |
