Abstract Objective To evaluate of left heart structure and function in patients with atrial fibrillation by real-time three-dimensional echocardiography (RT-3DE) and two-dimensional speckle tracking echocardiography(2D-STE). Methods A total of 65 patients with atrial fibrillation hospitalized in Department of Cardiology, Beijing Jishuitan Hospital from January 2018 to December 2020 were selected as observation subjects. According to the type of atrial fibrillation, they were divided into persistent atrial fibrillation (PerAF) group (30 cases) and paroxysmal atrial fibrillation (PAF) group (35 cases). RT-3DE and 2D-STE were used to collect images, and QLAB 13.0 analysis software was used， maximum left atrial volume (LAVmax), left atrial emptying fraction (LAEF), left atrial volume index (LAVI), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left atrial reservoir strain (LASr), left atrial conduit strain (LAScd), left atrial contraction strain (LASc), and left ventricular global longitudinal strain (GLS) were calculated. The related indicators of two groups were compared, and the correlation between LAVI and left atrium and left ventricle strain were analyzed. Results There were no significant differences in LAVmax between two groups (P > 0.05); LAVmin, LAVI, LVEDV, and LVESV in PerAF group were higher than those in PAF group, while LAEF was lower than that in PAF group, and the differences were statistically significant (P < 0.05). LASr, LAScd, LASc, and GLS in PerAF group were lower than those in PAF group, and the differences were statistically significant (P < 0.05). LAVI was negatively correlated with LASr, LAScd, LASc, and GLS (r =-0.47, -0.49, -0.63, -0.49, P < 0.01). Conclusion The left heart remodeling and functional impairment in patients with PerAF are more serious than those in patients with PAF. RT-3DE combined with 2D-STE can effectively evaluate the left heart structure and function in patients with atrial fibrillation.
