Cross-sectional study
Rheumatoid arthritis and cardiovascular complications during delivery: a United States inpatient analysis
- Retrospective cross-sectional study (National Inpatient Sample)
- US National Inpatient Sample 2004-2019
- ICD-9/ICD-10 codes
Authors' conclusion
Pregnant persons with RA had higher risk of preeclampsia, peripartum cardiomyopathy, arrhythmias, acute kidney injury, and venous thromboembolism during delivery hospitalizations. Furthermore, cardiometabolic risk factors among pregnant individuals with RA rose over this 15-year period.
