Background: Gestational diabetes mellitus is a condition in pregnancy where adverseperinatal outcomes in mother occurs.Effect of longstanding diabetesmellitus on adult heart might lead to dysfunction and diabeticcardiomyopathy. Microvascular processes and subcellular disturbancescause structural and functional damage to the diabetic heart, even without overt coronary artery disease.GDM patients might have impaired cardiacfunctions compared to healthy pregnant women. Objective: In view of this, this study was undertaken to assess the Maternal cardiac adaptation of women at term with and without GDM. Methods: A prospective study was conducted among 60 pregnant women, 30 with GDM and 30 without GDMduring2022 to2023admitted inthe department of obstetrics and gynaecology at Adichunchanagiri Institute of Medical Sciences, B.G Nagara, Karnataka. Results: There was no statistically significant difference in echocardiogenic findings of both groups. Results revealed that echocardiogenic parameters, including normal heart rate, left ventricular relative wall thickness, LV late diastolic transmitral valve velocity, Ejection fraction >60%,Pulmonary artery systolic pressure,IVC findings,regionalwall motion abnormality are normal.These findings suggest that diabetesdonot appear to have impact on echocardiac measures compared to normalANC women. Conclusion: These results suggest that during pregnancy the presence ofgestational diabetes maynot impact cardiac function compared to normalantenatal women.
