Abstract
The aim of this study was to assess systolic left ventricular function of patients with IDA using Echo-Doppler imaging, including tissue doppler imaging modality (TDI) and to determine whether this modality is an adequate diagnostic tool for the screening and detection of subclinical cardiac dysfunction in IDA .
This is a case-control study that included 30 patients with IDA who were following up in the outpatient clinic in Beni Suef University Hospital , and 30 ages and sex matched subjects taken as control. All patients were subjected to full history and through clinical examination . Serum ferritin as well as hemoglobin level of the patients at the time of study enrollment were also recorded.
Transthorathic resting echocardiography was recorded in patients with
IDA and in normal controls, where M-mode and two dimentional echocardiography were performed and measurements were obtained. TDI Tissue Doppler imaging , to determine LV function and to. Cardiac dimensions, systolic functions of the LV were obtained and values in IDA patients and in normal controls were compared.
Evaluation of LV systolic function was done by measurement of ,LVESD ,LVEDD ,LVEF , TDI to measure peak systolic velocity of mitral annulus (SM) to evaluate the LV systolic function.
The evaluation of IDA patients by different echocardiographic modalities revealed the following:
- Conventional echocardiography revealed no statistically significant difference in LV dimensions in patients in comparison with the control group.
-There was no significant difference in LV EF denoting delayed affection in LV systolic function among cases.
- Regarding LV systolic function, TDI derived SM was significantly lower in patients group in comparison with control group with P value (0.005) .
