Abstract INTRODUCTION: Preeclampsia affects about 5-10% of all pregnancies and is a major cause of maternal, fetal and neonatal mortality and morbidity. The cardiovascular system undergoes a host of changes in association with development of preeclampsia. LDH is a useful biochemical marker that reflects the severity of the occurrence of preeclampsia. METHOD AND MATERIALS: One hundred pregnant women were selected for this study, 50 normal pregnant women as controls and 50 preeclamptic women as the study group. Cardiac enzymes (serum LDH, serum AST, serum CK and serum CKMB) of these women were analyzed. RESULTS: Mean Serum LDH and mean serum AST concentrations were significantly higher in preeclamptic patients compared to normal pregnant women (348.34 ± 59.17 vs. 255.92 ± 43.26, P < 0.01) and (34.32 ± 10.37 vs. 22.06 ± 5.10, P < 0.01) respectively. CONCLUSION: LDH and AST may be increased due to liver damage. This endothelial vascular damage is the main cause in the occurrence of preeclampsia. Higher levels of LDH and AST are very useful markers to identify the occurrence of preeclampsia. Keywords: LDH, Preeclampsia, AST, Cardiac Enzymes.
