Fig. 2From: Relationship between spleen size and exercise tolerance in advanced heart failure patients with a left ventricular assist deviceDiagram of structural equation modeling to represent correlations/causal relationships among factors that influence peak VO2. BSA, body surface area; CO; cardiac output; HR: heart rate; PCWP: pulmonary capillary wedge pressure; RAP: right atrial pressure; RVSWI: right ventricular stroke work index; SBP: systolic blood pressure; peak VO2: peak oxygen consumptionBack to article page
