Result :(1)the percentage of NTG tolerance in Group Ⅱ and Group Ⅲ were lower than that of Group Ⅰ( P ＜0.05);(2)Captopril and non-sulfhydryl ACEI could inhibit the re-elevation of SBP and the decrease of platelet cGMP at the later stage during the NTG infusion;(3)Platelet cGMP could be an indicator of nitrate tolerance;(4)ACEI could decrease the production of vasoconstrictor substances such as Ang Ⅱ,ET and increase the production of vasorelaxant substances such as BK.

结果：①Ⅱ组和Ⅲ组耐药比例均较Ⅰ组低( P ＜0.05)；②加用Captopril和非巯基ACEI能使NTG滴注过程后期的SBP回升及血小板cGMP下降得到抑制；③血小板cGMP能反映NTG耐药；④ACEI能在NTG滴注过程中使缩血管物质减少、舒血管物质增多。
