Outcomes, Temporal Trends, and Resource Utilization in Ischemic versus Nonischemic Cardiogenic Shock

Cardiogenic shock (CS) is associated with significant morbidity and mortality. Differentiating the etiologic factors driving CS has epidemiological significance and aids in optimization of therapeutic strategies, prognostication, and resource utilization. The aim herein is to investigate the epidemiology and clinical outcomes of CS in those with ischemic and nonischemic CS etiologies. Using International Classification of Diseases codes, we queried the national inpatient sample for CS hospitalization from 2007 to 2018 and divided the study sample into cohorts of ischemic (I-CS) and nonischemic cardiogenic shock (NI-CS). We then compared the primary outcome of in-hospital mortality between these 2 cohorts. Two groups of secondary outcomes (clinical and procedural) were also assessed between the 2 cohorts. CS was present in 557,860 hospitalizations; 84% of these were I-CS and 15.8% NI-CS. Patients with I-CS were older, more commonly males, with more risk factors for coronary artery disease (P
