LVEDD: left ventricular end-diastolic diameter; LVESD: left ventricular end-systolic diameter; IVST: interventricular septal thickness; PWT: posterior wall thickness; MWT: maximum wall thickness; LVEF: left ventricular ejection fraction; LA-D: left atrium diameter; E/A ratio: early to late (A) ventricular filling velocities ratio; GLS: global longitudinal strain. Data are presented as mean ± SD. Mann–Whitney U test and independent sample t-test. Bold value implies statistical significance.
