Hypertensive disorders of pregnancy and gestational diabetes mellitus and predicted risk of maternal cardiovascular disease 10–14 years after delivery: A prospective cohort

Diabet MedPublished Secondary analysis of the HAPO Follow-up Study prospective cohort

Authors' conclusion

Individuals who experienced HDP or GDM had a higher predicted 10- and 30-year risk of ASCVD measured 10-14 years after delivery compared with individuals who did not experience these APOs.

Study context

Population
Pregnant individuals in the Hyperglycemia and Adverse Pregnancy Outcome Follow-up Study (2013–2016); median age 30.5 years, median gestational age 27.9 weeks at enrollment; 10.7% developed hypertensive disorders of pregnancy (HDP), 13.7% gestational diabetes mellitus (GDM)
Participants
4,432 individuals
Comparison
HDP vs no HDP; GDM vs no GDM
Primary endpoint
10- and 30-year predicted risk of ASCVD (composite of fatal and non-fatal coronary heart disease and stroke) by Framingham Risk Score, continuous
Follow-up
10-14 years after delivery

Primary result

As reported in the abstract

Predicted ASCVD risk (least squares mean)
HDP vs No HDP · 10-year: 2.9% vs. 2.2%
adj. β (10-year risk) 0.59 (95% CI 0.41–0.77)
HDP vs No HDP · 30-year: 7.7% vs. 6.1%
adj. β (30-year risk) 1.27 (95% CI 0.81–1.72)
GDM vs No GDM · 10-year: 3.2% vs. 2.1%
adj. β (10-year risk) 0.51 (95% CI 0.34–0.67)
GDM vs No GDM · 30-year: 8.8% vs. 5.8%
adj. β (30-year risk) 1.56 (95% CI 1.11–2.01)

Further findings

Predicted atherosclerotic cardiovascular disease (ASCVD) risk at thresholds ≥7.5% (10-year) and ≥20% (30-year) · 10-14 years after delivery

Results similar when assessed at thresholds of ≥7.5% at 10 years and ≥20% at 30 years
