the combination of captopril and isdn produced a greater fall in mean arterial pressure , a further rise in ejection fraction to 22 +/- 8 % ( p less than 0.05 ) , a fall in systemic ( p less than 0.05 ) and pulmonary vascular resistance ( p less than 0.01 ) and a rise in cardiac ( p less than 0.01 ) and stroke work index ( p less than 0.01 ) , while the beneficial effects of isdn on right-atrial , pulmonary arterial and wedge pressure were again achieved .
