降压治疗策略的新理念 ◆以长期高质量血压控制和预防或逆转靶器官损害为目标的优化治疗,更有利于指导降压治疗,并可能获得更大程度的益处。
不同治疗方案影响终点事件的临床试验 ● LIFE (2001) ● IDNT (2001) ● ASCOT-BPLA (2005) ● ACCOMPLISH (2008) ● COPE (2011)
优化治疗策略的意义 ◆优化治疗策略需要优化降压治疗的基本 元素、剂量,以及联合治疗方案与路径, Preferred drugs,Preferred combinations。 ◆RAS阻滞剂±钙拮抗剂±噻嗪类利尿剂 联合成为临床上主要的优化治疗方案。 ◆ 新观念和新思路将开拓高血压治疗的新 靶点,推动新药与新制剂研发。
