Abstract
Background: There are limited sex-specific data on patients receiving temporary mechanical circulatory support (MCS) for acute myocardial infarction-cardiogenic shock (AMI-CS). Methods: All admissions with AMI-CS with MCS use were identified using the National Inpatient Sample from 2005 to 2016. Outcomes of interest included in-hospital mortality, discharge disposition, use of palliative care and do-not-resuscitate (DNR) status, and receipt of durable left ventricular assist device (LVAD) and cardiac transplantation. Results: > 0.05). Women had higher use of palliative care, DNR status, and discharges to skilled nursing facilities. Conclusions: There are persistent sex disparities in the outcomes of AMI-CS admissions receiving MCS support. Women have higher in-hospital mortality, palliative care consultation, and use of DNR status.
