Atrial Fibrillation Impacts Inpatient Mortality, Length of Stay, Resource Utilization, Blood Transfusion, and Endotracheal Intubation in Cesarean Sections, Natural Spontaneous Deliveries, and Instrumental Deliveries: A Nationwide Analysis (2016-2020).

Background: Atrial fibrillation (AF) is rare during pregnancy and current data on the impact of AF during delivery is scarce. In this study, we aim to analyze the impact of AF in patients who underwent delivery via cesarean section (CS), natural spontaneous delivery (NSD), or instrumental delivery (ID).

Methods: This study analyzed discharge data from the National Inpatient Sample (NIS) from 2016 to 2020.

Differences in the Impact of Obesity and Bariatric Surgery on Patients Hospitalized for Atrial Flutter and Atrial Fibrillation: A Nationwide Analysis, 2016-2020.

Background: The "obesity paradox" claims that although obesity is a risk factor for atrial fibrillation, obese patients have lower inpatient mortality when admitted due to atrial fibrillation. This study aims to analyze if the obesity paradox still holds true after weight loss from bariatric surgery.  Methods: This study analyzed discharge data from the National Inpatient Sample, 2016-2020.
