23、ACC关于高血压合并冠心病降压治疗的声明,在高血压合并各种冠心病的患者中,受体阻滞剂与血管紧张素转化酶抑制剂(ACEI)具有不可替代的作用。但因患者目标治疗血压较低,多数患者需要联合使用钙离子拮抗剂,才能有效控制血压,控制心绞痛症状。,Rosendorff C,et al.Circulation.2007;115:2761-88,稳定性冠心病降压治疗ACEI联合DHP-CCB,作用特点 同时扩张动、静脉 抗心绞痛作用 抑制反射性交感激活 抗动脉粥样硬化作用 改善胰岛素敏感性 与他汀类有协同作用 优势人群 左心室功能减退 心绞痛和心肌缺血 糖尿病 血压较高,ACEI DHP-CCB,结论,高血压合并冠心病患者的降压治疗，应坚持个体化原则，缓慢降到安全而又获益的水平阻滞剂和ACEI可改善冠心病患者预后,同时可有效降压,因此在合并冠心病的高血压治疗中备受重视稳定性冠心病患者联合应用ACEI和钙拮抗剂可进一步降低心血管事件的风险,Thank you,
