Comparative Study of Coagulation Profile and Haematological Parameters in Pregnancy-Induced Hypertension (PIH).

Background Pregnancy-induced hypertension (PIH) is a major cause of maternal and fetal morbidity and mortality. PIH, including gestational hypertension, pre-eclampsia, and eclampsia, often leads to significant alterations in coagulation profiles and haematological parameters, posing risks for thromboembolic and haemorrhagic complications. This study aimed to compare the coagulation and haematological parameters between women with PIH and normotensive pregnant women. Methods A cross-sectional observational study was conducted on 110 pregnant women, divided into two groups: 55 with PIH and 55 with normotensives. Coagulation markers such as prothrombin time (PT), activated partial thromboplastin time (aPTT), international normalised ratio (INR), and platelet count were measured. Bleeding and clotting times were also evaluated. Data were statistically analysed using student's t-test and chi-square tests, with p ≤ 0.05 considered significant. Results Women with PIH exhibited significantly lower platelet counts, PT, aPTT, and INR values compared to the normotensive group (p < 0.0001). Thrombocytopenia and prolonged bleeding time were more common in the PIH group, suggesting an increased risk of both bleeding and clotting complications. Proteinuria was observed in 32 women (58.18%) in the PIH group, reflecting the severity of the disease. Additionally, the PIH group had markedly elevated blood pressure levels. Conclusion PIH is associated with significant coagulation and haematological abnormalities, including thrombocytopenia and a hypercoagulable state, which increase the risk of thromboembolic and hemorrhagic events. Routine monitoring of coagulation profiles and haematological parameters in PIH patients is essential for timely interventions and improving maternal and fetal outcomes.
