Abstract

Background: Gestational diabetes (GD) is associated with increased risk of long-term cardiovascular complications. However, data on acute peripartum cardiovascular complications are not well established. Hence, we aimed to investigate the association of GD with acute cardiovascular outcomes at the time of delivery admission.

Methods and Results: We used data from the National Inpatient Sample (2004-2019). International Classification of Diseases, Ninth Revision (ICD-9) or Tenth Revision (ICD-10) codes were used to identify delivery hospitalizations and GD diagnosis. A total of 63 115 002 weighted hospitalizations for deliveries were identified, of which 3.9% were among individuals with GD (n=2 435 301). The prevalence of both GD and obesity increased during the study period (P trends< 0.01). Individuals with GD versus those without GD had a higher prevalence of obesity, hypertension, and dyslipidemia. After adjustment for age, race or ethnicity, comorbidities, insurance, and income, GD remained independently associated with cardiovascular complications including preeclampsia (adjusted odds ratio [aOR], 1.97 [95% CI, 1.96-1.98]), peripartum cardiomyopathy (aOR, 1.15 [1.08-1.22]), acute kidney injury (aOR, 1.16 [1.11-1.21]), stroke (aOR, 1.15 [1.09-1.23]), and arrhythmias (aOR, 1.48 [1.46-1.50]), compared with no GD. Moreover, delivery hospitalizations among individuals with GD were associated with increased length (3 versus 2 days, P< 0.01) and cost of hospitalization ($4909 versus $3682, P< 0.01). Even in the absence of preeclampsia, GD was associated with elevated cardiovascular risk.

Conclusions: Individuals with GD had a higher risk of preeclampsia, peripartum cardiomyopathy, acute kidney injury, stroke, and arrhythmias during delivery hospitalizations. As rates of GD are increasing globally, efforts to improve preconception cardiometabolic health and prevent GD may represent important strategies to improve peripartum maternal outcomes and mitigate long-term cardiovascular risk.
