硝酸甘油的抗心绞痛作用:

A

A. 扩张静脉血管,降低心脏前负荷
B. 扩张冠状动脉和铡侧支血管促进侧支血管开放,增加缺血区的血流量
C. 降低左心室舒张末期内压,减轻心内膜下血管所受的挤压,增加心内膜下缺血区血流量
D. 扩张动脉血管,降低外周阻力,降低心脏后负荷

17
Q

普萘洛尔抗心绞痛机制为:

A

A. 减慢心率,减少耗氧量
B. 减弱心肌收缩力,降低心肌耗氧量
E. 延长心舒张期,促进血液从心外膜流向心内膜缺血区

18
Q

硝酸甘油和普萘洛尔合用治疗心绞痛:

A

A. 两药都降低心肌耗氧量,合用后可产生协同抗心绞痛作用
C. 硝酸甘油加快心率和加强心肌收缩力可被普萘洛尔取消
