Mechanical circulatory device utilization in cardiac arrest: Racial and gender disparities and impact on mortality.

The objectives of this retrospective study include identifying the utilization trend of mechanical circulatory devices (MCD) such as Intra-Aortic Balloon Pump (IABP), Impella and Extracorporeal Membrane Oxygenation (ECMO) in admissions with cardiac arrest, determining whether racial or gender disparities exist in their usage, and discerning if their use is associated with a reduction in mortality. By leveraging the National Inpatient Sample, we identified 229,180 weighted adult cardiac arrest admissions between October 1, 2015 and December 31, 2018. MCD were used in 6005 admissions (2.
