Data are presented as mean ± SD and number (percentage).
*Chi-square test and Student’s 𝑡-test.
CAD: coronary artery disease; LA AP diameter: left atrium anteroposterior diameter; LVEDD: left ventricular end diastolic dimension; LVESD: left ventricular end systolic dimension; LV EF: left ventricle ejection fraction (Simpson's).
𝑃<𝟎.𝟎𝟓 = statistically significant.
