Abstract
Objective: The present study aimed to evaluate left ventricular (LV) systolic function in patients with iron deficiency anemia (IDA) by 3-dimensional speckle-tracking echocardiography (3DSTE).Methods: Participants were grouped by hemoglobin (Hb) levels in order to study the effect of anemia on cardiac function. Group A included 40 healthy volunteers. Eighty-three patients who were diagnosed with IDA were divided into 2 groups according to the Hb level. Group B (Hb 9 g/dL) included 44 patients, while group C (Hb 6-9 g/dL) included 39 patients. Left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular mass index (LVMI), and left ventricular ejection fraction (LVEF) were calculated by real-time 3-dimensional echocardiography (RT3D). Left ventricular global longitudinal strain (GLS), global area strain (GAS), global radial strain (GRS), and global circumferential strain (GCS) were obtained by 3DSTE.Results: LVMI, LVEDV and LVESV of group C increased and GCS, GRS, GLS, and GAS of group C decreased compared with those of groups A and B (all p< 0.05). GAS and GLS decreased significantly compared with other parameters (both p< 0.01).Conclusion: LV remodeling and LV systolic dysfunction occurred in patients when the hemoglobin level was in the range of 6-9 g/dL. 3DSTE can evaluate LV systolic function in patients with IDA, and GAS and GLS are more sensitive than other parameters.
