- LV left ventricular, CMR cardiac magnetic resonance imaging, n number of subjects, AC anthracycline, EF ejection fraction, EDVI end diastolic volume index, ESVI end systolic volume index, SV stroke volume, ESFS end systolic fiber stress; εcc peak global circumferential strain magnitude; ειι: Peak global longitudinal strain magnitude. All patients in the low dose group had diagnosis of leukemia or lymphoma with Anthracycline cumulative doses of 175.2 ± 21.4 compared to 447.3 ± 4.6 (p < .0001) in the high dose group (solid tumor diagnosis)
- Bold numbers indicate statistically significant cardiac magnetic resonance imaging parameters
