Anemia in pregnancy: it's effect on oxidative stress and cardiac parameters

Objective We aimed to evaluate the changes in cardiac functions by echocardiography and oxidative stress markers in pregnant women with iron deficiency anemia. Method A total of 100 patients (pregnant women with IDAn = 34, healthy pregnant womenn = 33, non-pregnant control groupn = 33) were enrolled. Demographic data, serum thiol-disulfide and ischemia modified albumin levels, and echocardiographic parameters were compared. Results Native thiol (NT) (p < .001) and Total Thiol (TT) (p < .001) levels as antioxidant markers; left ventricular ejection fraction (LVEF) (p < .001), tricuspid annular plane systolic excursion (TAPSE) (p < .001) were significantly decreased in the IDA group compared to healthy pregnant women and non-pregnant controls. Adjusted IMA ratios were significantly increased in the IDA group (p =.001). A significant negative correlation was determined between adjusted IMA and LVEF (r = -0,4226;p =.016), a significant positive correlation was determined between thiol levels and TAPSE (r = 0.361;p =.041) in IDA group, no correlation was observed in healthy pregnant women and healthy non-pregnant control group. Conclusion Anemia in pregnanc may trigger oxidative stress and increased OS may be related to changes in cardiac functions. The possible cardiovascular impact should be considered in pregnant women with anemia and clinicians should not neglect to refer these patients to cardiology in clinical practise.
