Assessment of left ventricular systolic function in children with iron deficiency anemia by two-dimentional echocardiography and tissue Doppler in Beni- Suef university hospital

Abstract

Cardiac structure and function in iron deficiency anemia are mainly affected by two competing factors: iron deficiency and increased cardiac output (CO). Anaemia and iron deficiency (ID) are common causes of heart failure, both separately and in combination.The goal of this study is to assess the systolic function of left ventricle in ( IDA )using tissue doppler in pediatrics . Sixty (60) children grouped into two groups,one with IDA and another control group. All candidates were suspected to history taking, full clinical examination ,complete blood count ,iron profile and echocardiographic examination. There was significant difference between cases and controls regarding peak systolic velocity across mitral annulus (SM) using tissue doppler imaging . There was no significant difference in left ventricle (LV) dimentions between cases and controls, The mean value of LVESV in case group was 2.0 ± .28 cm while it was 2.1 ± .3 cm in control P value was (.64) . There was no correlation between HB level or ferritin level and SM or EFThe study revealed preserved LV systolic functions as detected by conventional echocardiography however tissue Doppler imaging technique had shown latent LV systolic dysfunction Further follow up is needed for cases to assess reversability of finding .
