  1. Values are displayed as median (interquartile range). Two patients were lost to follow-up regarding MACE. P-values were calculated for the comparison between patients with and without MACE using the Mann–Whitney U test. Numbers in bold indicate a statistical significance in difference
  2. EDVI: end-diastolic volume index; ESVI: end-systolic volume index; GLS: global longitudinal strain, LA: left atrial, LACI: left atrioventricular coupling index, LVEF: left ventricular ejection fraction
