Preeclampsia as an independent predictor of atherosclerosis progression in women with type 1 diabetes: a 5-year prospective study

Cardiovasc DiabetolPublished Prospective cohort study

Authors' conclusion

PE was a strong independent predictor of atherosclerosis progression over a 5-year follow-up period, with an additive effect in T1D. These findings highlight preeclampsia as a significant CVD risk enhancer in young women with T1D.

Study context

Population
Women with or without T1D and with or without a history of preeclampsia (PE); mean age at inclusion 45.2 ± 7.6 years104 completed follow-up
Participants
112 women
Exposure
T1D and/or preeclampsia vs neither
  • T1D + /PE +n = 28
  • T1D + /PE-n = 28
  • T1D-/PE +n = 28
  • T1D-/PE-n = 28reference
Outcome
Atherosclerosis progression: increase in carotid plaque number or a cardiovascular event (fatal or non-fatal ischemic heart disease, fatal or non-fatal stroke, and/or HF)
Follow-up
5 years (mean 5.3 ± 1.2 years)
