  1. Data are presented as mean ± standard deviation \((\overline{x} \pm s)\), median (interquartile range) or n (%). BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; CHD, coronary heart disease; LAD, left atrial diameter; LVEDD, left ventricular end-diastolic diameter; LVESD, left ventricular end-systolic diameter; LVEF, left ventricular ejection fraction; AADs, include class I and Class III antiarrhythmic drugs; ACEIs/ARBs, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers. p < 0.05 was considered statistically significant.
