Key result
Prior gestational diabetes or hypertension is linked to ~19% higher CVD risk in T2D.
Why the study?
The study investigated the contribution of antecedent gestational diabetes mellitus or gestational hypertensive disorder to the risk of cardiovascular disease among women with Type 2 diabetes.

Does a history of gestational diabetes mellitus or gestational hypertensive disorder increase the risk of cardiovascular disease in women with Type 2 diabetes?
A history of gestational diabetes or gestational hypertension independently increases the risk of cardiovascular disease in young women with Type 2 diabetes, highlighting the need for aggressive cardiovascular risk factor modification in this population.

Associated higher CVD risk in T2DM women warrants caution in risk assessment; leaves open whether pregnancy history refines stratification or prevention.
AIM: We investigated the contribution of antecedent gestational diabetes mellitus (GDM) or gestational hypertensive disorder (GHTD) to the risk of cardiovascular disease (CVD) among women with Type 2 diabetes mellitus (T2DM). METHODS: In a population-based cohort using the Ministry of Health of Ontario (Canada) healthcare administrative data, women without prior CVD with T2DM and a history of GDM or GHTD as of 1 January 2018 (n = 11 525, mean age: 43 years) were age-matched to three comparator cohorts (women with T2DM and no history of GDM or GHTD [n = 11 525], women without T2DM and without GDM or GHTD [n = 11 525] and men with T2DM [n = 11 525]). Incident CVD (coronary artery disease [CAD] and cerebrovascular disease) and heart failure (HF) were assessed until 31 December 2023. RESULTS: There were 1231 CVD events over a median follow-up of 6 years. Compared to women with T2DM but no history of GDM or GHTD, women with T2DM and a history of GDM or GHTD exhibited higher incident CVD (adjusted hazard ratio [aHR]: 1.19, 95% CI: 1.01, 1.41) and CAD (aHR: 1.35, 95% CI: 1.10, 1.66) risks. They also had higher CVD (aHR: 3.70, 95% CI: 2.79, 4.91), CAD (aHR: 4.96, 95% CI: 3.43, 7.19), cerebrovascular disease (aHR: 2.41, 95% CI: 1.54, 3.76) and HF (aHR: 4.95, 95% CI: 2.05, 11.94) risks versus women without T2DM and no history of GDM or GHTD. However, they had lower CVD, CAD, cerebrovascular disease and HF risks, compared to men with T2DM. CONCLUSIONS: Among women with T2DM, prior GDM or GHTD conferred a higher CVD risk.

Echouffo‐Tcheugui et al. (2026) conducted a cohort in Type 2 diabetes mellitus with history of gestational diabetes or gestational hypertensive disorder (n=46,100). History of gestational diabetes mellitus or gestational hypertensive disorder vs. Women with Type 2 diabetes and no history of GDM or GHTD was evaluated on Composite cardiovascular disease (hospitalization for myocardial infarction, acute coronary syndrome, coronary artery bypass surgery, percutaneous coronary intervention, stroke or carotid endarterectomy) (aHR 1.19, 95% CI 1.01, 1.41). A history of gestational diabetes or gestational hypertensive disorder in women with type 2 diabetes increased the risk of incident cardiovascular disease by 19% compared to women with type 2 diabetes without such history.
