Table 1 Essential characteristics and global left ventricular (LV) parameters derived from cardiovascular magnetic resonance (CMR) cine images in the evaluation step (healthy subjects) and validation step (healthy subjects and cardiac amyloidosis patients). Age and LV parameters are given as mean ± standard deviation. EDV = end-diastolic volume; EF = ejection fraction
Subjects | Field strength | N | Age (years) | Male/ female | LV EDV (ml) | LV mass (g) | LV EF (%) | |
