Values are mean ± SEM or median (25th-75th percentiles).
CMR = cardiac magnetic resonance; ID = iron deficiency; LV = left ventricular; LVEDV = left ventricular end-diastolic volume; LVEF = left ventricular ejection fraction; LVESV = left ventricular end-systolic volume.
a
Values from 90 patients with adequate measurements.
b
Values from the 109 patients (45 with ID and 64 without ID) with cardiac magnetic resonance imaging repeated at 6 months.
