Abstract

Despite advances in temporary mechanical circulatory support (TMCS), in-hospital mortality and morbidity related to cardiogenic shock due to ST elevation myocardial infarction (CS-STEMI) are highly prevalent. We identified admissions with CS-STEMI between 2016 and 2019 from the National Readmission Database (NRD). Among 80 997 patients with CS-STEMI, we identified 42,139 without TMCS, while the remaining received various types of TMCS (Extra corporeal membrane oxygenation [ECMO] alone: n = 753; Intra-aortic balloon pump [IABP] alone: n = 27 556; Impella alone: n = 9055; ECMO with IABP or Impella: n = 1494). 30-day readmission rates did not differ among groups, whereas 90-day readmissions were higher among those with combined ECMO and IABP or Impella support ( = .027). In-hospital mortality and complications including hemodialysis, transfusion, and stroke were the highest in the Impella and combined ECMO and IABP/Impella groups. Heart failure was the most common cause of readmission. Multivariable logistic regression revealed female gender, diabetes, prior myocardial infarction, heart failure, chronic kidney, and peripheral artery disease as risk factors for 90-day readmissions. Our study unveiled several important factors associated with readmission and mortality related to TMCS in CS-STEMI. Approaches to identify and prevent readmissions by addressing these factors may lead to lower morbidity, healthcare cost related to readmission, and improved quality of life.
