Right atrial volume index to left atrial volume index ratio is associated with adverse clinical outcomes in cardiogenic shock

Background Structural remodeling in chronic systolic heart failure (HF) is associated with neurohormonal and hemodynamic perturbations among HF patients presenting with cardiogenic shock (CS) and HF. Our objective was to test the hypothesis was that atrial remodeling marked by an increased right atrial volume index (RAVI) to left atrial volume index (LAVI) ratio is associated with adverse clinical outcomes in CS. Methods Patients in this cohort were admitted to the intensive care unit with evidence of congestion (pulmonary capillary wedge pressure > 15) and cardiogenic shock (cardiac index
