Abstract
Introduction: There are conflicting data on COVID-19 outcomes in pregnant women. Using the AHA COVID-19 CVD Registry we evaluated COVID-19 outcomes in pregnant vs non-pregnant women with COVID-19. Methods: Women 18-40 years old hospitalized from March 2020 to December 2021 with symptomatic COVID-19 were included (n=2,068), with 110 (5.3%) pregnant at admission. Women with unknown pregnancy status were excluded. Vaccine data were limited (2.8% of participants), therefore omitted from analysis. Baseline demographics and symptoms at presentation were compared between pregnant and non-pregnant women (Table). Rates of death, mechanical ventilation, ICU admission, hospital stay ≥5 days, myocardial infarction, stroke, DVT, PE, and a composite of all outcomes were determined. Multivariable Cox regression analyses were performed, adjusting for comorbidities and prior CVD. Results: Pregnant women hospitalized with COVID-19 had fewer comorbidities than non-pregnant women (Table). There were no deaths in the pregnant group and 44 (2.3%) in the non-pregnant group. Fewer pregnant women were hospitalized ≥5 days (29.1% vs 41.2% non-pregnant); this difference was not statistically significant after multivariable adjustment [adjusted HR (95% CI), 0.67 (0.43-1.02)]. There were no significant differences between the groups in the composite outcome [adjusted HR (95% CI), 0.72 (0.48-1.07)] or its components (Table). Conclusions: Pregnant women hospitalized with symptomatic COVID-19 had fewer comorbidities compared with non-pregnant women. There were fewer deaths and lower rates of hospitalization ≥5 days in pregnant vs non-pregnant women which was no longer statistically significant after multivariable adjustment. The potential for residual confounding due to healthier pregnant women presenting with milder COVID-19 illness or being admitted for non-COVID-19 indications compared to non-pregnant women must be considered when interpreting these findings.
