BACKGROUND: Pulseless ventricular tachycardia/ventricular fibrillation (VT/VF) is the initial rhythm in a third of in-hospital cardiac arrest patients. Mechanical circulatory support (MCS) device use remains poorly understood in this population.
METHODS: We conducted an observational analysis of temporal trends in the utilization of MCS in VT/VF IHCA between January 2008 and December 2014 utilizing the Nationwide Inpatient Sample (NIS) database. Using multivariable analysis, we assessed factors associated with MCS use and survival to discharge.
RESULTS: Among 151,628 hospitalizations with VT/VF IHCA, 14,981 (9.9%) received MCS. Intra-aortic balloon pump (IABP) was the most commonly used MCS (9.1%). From 2008 to 2014, there was significant increase in the utilization of MCS (8.7-11%; p
CONCLUSION: There was significant increase in utilization of MCS after VT/VF IHCA during the study period. IABP was the most commonly utilized MCS. The survival to hospital discharge increased in the overall study population including both MCS and non-MCS groups. Future studies are needed to identify patient population most likely to benefit from the use of MCS after VT/VF IHCA.
