Objective: To explore the relationship between gestational diabetes and long-term cardiovascular risk in women. Methodology: This study employed a retrospective cohort design to examine the long-term cardiovascular outcomes in women with a history of gestational diabetes mellitus (GDM). Data were collected from hospital records of women diagnosed with GDM during pregnancy, tracking their subsequent cardiovascular health over a period of 10 years. Statistical analyses were conducted to compare the incidence of cardiovascular diseases between women with and without a history of GDM, adjusting for confounding factors such as age, parity, and socioeconomic status. Results: The results revealed a significant increase in the incidence of cardiovascular diseases among women with a history of GDM, including ischemic heart disease, hypertension, and heart failure. Women with GDM had more than double the risk of cardiovascular events compared to those without GDM. The study also found that older maternal age, preeclampsia, and lower socioeconomic status were additional factors contributing to increased cardiovascular risk in this population. Conclusion: The study highlighted that women with a history of GDM face a heightened risk of cardiovascular diseases later in life. This finding emphasizes the importance of long-term cardiovascular surveillance and early interventions for women with GDM. Public health strategies should focus on preventing cardiovascular outcomes in this high-risk group through lifestyle modifications, medical management, and targeted health interventions.
