Being many research works are going on, how pregnancy aggravates hypertension remains unsolved. Hypertensive disorders remain among the most significant and interesting unresolved issues in obstetrics. Preeclampsia is also considered as a cardiovascular disease risk factor and many studies have shown preeclampsia increases the prevalence of various cardiovascular risk factors, such as hypertension, insulin resistance, metabolic syndrome, micro albuminuria and endothelial dysfunction. In this study, we aimed to study about any possible relationship between the ABO/Rh blood group system and hypertensive disorders in pregnant women.
Materials & Methods: A retrospective study was carried out 8182 pregnant women who camefor safe confinement during a period of one year from January 2019 to December 2019 in department of Obstetrics and Gynecology in a tertiary care center, Maharashtra. All the cases were analyzed for ABO blood group & Rh typing, systolic and diastolic blood pressure were monitored and correlated for each other.
Result: The frequency of ABO blood groups in hypertensive cases was found to be B & Gt; O & Gt; A & gt; AB. Rh typing was positive is more common. The prevalence of blood group B found to be increased in hypertensive group by 36.29%, prevalence of blood group O, A and AB was found to 27.27%, 20.29% and 10.67% respectively.
Conclusion: Blood group B POSITIVE was more susceptible to hypertensive disorders in pregnancy.
