| All-cause mortality (%) | 7 (7.8) | 11 (12.2) | 0.457 |
| Data are expressed as mean (standard deviation) or as number (percentage). LAE – left atrial enlargement; BMI – body mass index; DM – diabetes mellitus; CAD – coronary artery disease; F/U – follow-up; LA – left atrium; LVEF – left ventricular ejection fraction; MR – mitral regurgitation; HF – heart failure. | |||
