Five-year risk of all-cause death and cardiovascular events in women with gestational diabetes and hypertensive disorders of pregnancy.

BACKGROUND

The long-term impact of gestational complications on cardiovascular outcomes in women remains a subject of debate.

AIM

To assess the 5-year risk of cardiovascular events and all-cause mortality in women with gestational diabetes and hypertension.

METHODS

Retrospective study utilising an health research network(TriNetX). The primary outcome was the composite risk of a cardiovascular event within 5 years with secondary outcomes being its components (all-cause death, acute heart failure, myocardial infarction, ischaemic stroke). Women were categorised into 8 different groups based on the ICD-codes for pregnancy related complications recorded 9 months before the delivery:1) gestational diabetes,2) gestational hypertension,3) gestational diabetes with gestational hypertension,4) gestational diabetes with gestational hypertension without pre-eclampsia or eclampsia,5) gestational diabetes with pre-eclampsia or eclampsia,6) gestational hypertension without pre-eclampsia or eclampsia,7) pre-eclampsia or eclampsia,and 8) no gestational complications. Cox-regression analyses were used to produce hazard ratios (HRs) and 95% confidence intervals (CI) before and after propensity score matching (PSM).

RESULTS

We identified, 24,402 women with gestational diabetes and gestational hypertension and 920,478 without gestational complications. After PSM, compared to women without pregnancy complications, women with gestational diabetes and gestational hypertension had a higher 5-year risk of composite outcome(HR 2.25,95%CI 2.02-2.51), all-cause death(HR 1.64,95%CI 1.31-2.06), acute heart failure(HR 2.06,95%CI 1.69-2.52), myocardial infarction(HR 2.46,95%CI 1.93-3.14), and ischemic stroke(HR 2.37,95%CI 2.06-2.74). Women who experienced pre-eclampsia or eclampsia showed the highest risk of primary and secondary outcomes.

CONCLUSIONS

Gestational complications are associated with worse long-term cardiovascular outcomes. There is a clear call to action required to improve the longitudinal management of gestational complications to improve women's long-term health.
