A, Change in peak cardiac output (Qtmax) and maximum aerobic capacity (V̇o2max) in a subset of patients with evidence of low ventricular filling pressures after administration of intravenous fluid. B, This was associated with increases in V̇o2max and in peak stroke volume (SVmax), right atrial pressure (RAPmax), and pulmonary capillary wedge pressure (PCWPmax) in responders (filled symbols) compared to nonresponders (open symbols). Statistical significance was determined using the Student paired t test, and P values are noted above the brackets. Ca-An external file that holds a picture, illustration, etc.
