Cox regression analysis was used. Data in parentheses are 95% confidence intervals. LVEF = left ventricular ejection fraction, LVEDVI = left ventricular end-diastolic volume index, LVMI = left ventricular mass index, LAI = left atrium index, RVEF = right ventricular ejection fraction, RVEDVI = right ventricular end-diastolic volume index, GLS = global longitudinal strain, GCS = global circumferential strain, GRS = global radial strain, LGE = late gadolinium enhancement. Values in bold denote statistical significance.
