Figure 1 A, The absolute change in percent FMD following therapy compares with pretreatment baseline values. Only quinapril resulted in a significant improvement in brachial flow-mediated vasodilation (*p < 0.02). B, The absolute change in the ratio of percent FMD/nitroglycerin-induced vasodilation following therapy compared with baseline values. Again only quinapril resulted in significant improvement (*p = 0.03).
