Obstetrical Complications and Long-Term Cardiovascular Outcomes

Obstetrical complications including indicated preterm birth (PTB), hypertension (HTN), IUGR, and GDM are risk factors for future cardiovascular disease. To identify patients at risk, the American Heart Association recommends obtaining a detailed obstetric history. Our objective was to determine if non-OB-GYN physicians-in-training obtain an obstetric history when assessing a risk profile for cardiovascular disease and to identify differences based on level of training. In 2019, an anonymous survey was distributed to trainees in internal medicine, cardiology, endocrinology, nephrology, and neurology. Subjects were queried about frequency of asking a history of PTB, IUGR, GDM, and HTN in pregnancy. Survey options were always/frequently/sometimes/rarely/never and were categorized into two groups: "ask" (always/frequently/sometimes) vs. "do not ask" (rarely/never). Comparisons between specialties and levels of training were made using chi-square and Fisher's exact test. Comparisons within subjects were made using McNemar's test.

The response rate was 64% (210 total possible participants), including 98 internal medicine residents and 37 fellows in cardiology (21), endocrinology (3), nephrology (8), and neurology (5). Asking about medical complications (HTN + GDM) was significantly more common than asking about OB complications (PTB + IUGR) (p < 0.001). Internal medicine residents were less likely than subspecialty fellows to ask about HTN (31% vs. 70%; p < 0.001). There were no differences in likelihood of eliciting OB history based on PGY level. An OB history can identify risk factors for cardiovascular morbidity. Our data demonstrates that physicians caring for women lack awareness on the association between complications in pregnancy and cardiovascular health.
