The CHA<\/jats:styled-content>2DS<\/jats:styled-content>2\u2010VAS<\/jats:styled-content>c score was calculated for each patient. Additionally, blood samples were taken from all patients and transthoracic echocardiographic measurements were made. Left atrial mechanical functions and AEMD<\/jats:styled-content> were calculated.<\/jats:p><\/jats:sec>Results<\/jats:title>Mean CHA<\/jats:styled-content>2DS<\/jats:styled-content>2\u2010VAS<\/jats:styled-content>c score measured was 2.24\u00a0\u00b1\u00a01.53 in PAF<\/jats:styled-content> group. There was no significant difference between the groups when the patients were evaluated for baseline characteristics and laboratory parameters (P\u00a0>\u00a00.05) The echocardiographic evaluation of LA<\/jats:styled-content> mechanical functions showed that only LA<\/jats:styled-content> minimum volume (19\u00a0\u00b1\u00a06.4 vs. 16.7\u00a0\u00b1\u00a04.6, P\u00a0=\u00a00.02) and LA<\/jats:styled-content> presystolic volume (28.9\u00a0\u00b1\u00a07 vs. 25.1\u00a0\u00b1\u00a05.7, P\u00a0=\u00a00.01) were higher in the PAF<\/jats:styled-content> group. When AEMD<\/jats:styled-content> was compared between the groups; lateral PA<\/jats:styled-content>, septal PA<\/jats:styled-content>, tricuspid PA<\/jats:styled-content>, Interatrial EMD<\/jats:styled-content>, and intraatrial EMD<\/jats:styled-content> were significantly extended compared to control group (P\u00a0<\u00a00.001) CHA<\/jats:styled-content>2DS<\/jats:styled-content>2\u2010VAS<\/jats:styled-content>c score was correlated with Lateral atrial PA<\/jats:styled-content> (P\u00a0<\u00a00.001, r\u00a0=\u00a00.524), Septal atrial PA<\/jats:styled-content> (P\u00a0<\u00a00.001, r\u00a0=\u00a00.45), Interatrial EMD<\/jats:styled-content> (P\u00a0<\u00a00.001, r\u00a0=\u00a00.54), and intraatrial EMD<\/jats:styled-content> (P\u00a0<\u00a00.001, r\u00a0=\u00a00.51) times.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>The present study shows that AEMD<\/jats:styled-content> times increase in patients with PAF<\/jats:styled-content> compared to the control group.
