Trends in Temporary Mechanical Circulatory Support in Post-surgical Cardiogenic Shock

In this study seeking large-scale data on mechanical circulatory support (MCS) in post-cardiac surgery cardiogenic shock (PCCS) patients, researchers looked at a retrospective cohort of PCCS patients without MCS from the National Inpatient Sample between 2005 and 2014. The primary study outcomes was in-hospital mortality, with secondary outcomes including trends in use, costs and lengths of stay. There were 32,485 PCCS admissions, with 51.3% requiring MCS. The results indicated a decrease in MCS use across all demographic categories and hospital characteristics over time. The authors concluded that “in patients with PCCS, this study noted a steady decrease in MCS use. Use of MCS identified PCCS patients at higher risk for in-hospital mortality and greater resource utilization.”
