Severe Maternal Morbidity According to Mode of Delivery Among Pregnant Patients With Cardiomyopathies
Authors' conclusion
In patients with cardiomyopathies, a trial of labor does not confer a higher risk of maternal morbidity, blood transfusion, or readmission compared with planned cesarean delivery.
Study context
- Population
- Pregnant patients with a cardiomyopathy, Premier inpatient administrative database
- Participants
- 2,921 deliveries
- Exposure
- Intended vaginal delivery vs intended cesarean delivery
- Outcome
- Nontransfusion severe maternal morbidity during delivery hospitalization, blood transfusion and readmission
Methodological detailstarget trial emulation
