中国高血压防治疗指南中国高血压防治疗指南 (2010)(2010)心血管高危患者建议
• 收缩压≥ 180mmHg 和 / 或 舒张压≥ 110mmHg
• 糖尿病• ≥3 个心血管危险因素• 伴 1 个或多个亚临床器官损害 :
– 心电图 ( 尤其是心肌劳损 ) 或超声心动图 ( 尤其是向心性 ) 左心室肥厚– 超声检查显示颈动脉壁增厚或斑块– 动脉硬度增加– 血清肌酐轻度升高– 估测的肾小球滤过率或肌酐清除率下降– 微量白蛋白尿或蛋白尿
• 临床心、脑血管病或慢性肾脏疾病
★★★
中国高血压防治指南 (2005)降压治疗的实施过程
对高血压患者临床评价后,进行心血管危险水平分层 ( 低危、中危、高危、很高危 )
所有患者都应采用非药物治疗措施
制定降压治疗计划,确定血压控制目标值 很高危、高危患者:立即开始药物治疗 中危:随访观测数周,然后决定是否开始药物治疗 低危:随访观测数月,然后决定是否开始药物治疗
治疗随访,调整治疗方案

欧洲高血压治疗指南修改背景(ESC/ESH,2009)
欧洲高血压治疗指南修改要点(ESC/ESH,2009)
◆ 重申心血管危险分层
◆ 推荐 80 岁以上高龄高血压患者实施降压治疗
◆ 解释启动降压治疗血压水平和血压控制目标
一般人群:≥ 140/90 , <140/90
高危以上人群: < 130/85 , <130/80
◆ 建议在心血管高危患者血压控制不低于 120/70 。
◆ 淡化一线降压药物概念,强调首选联合治疗,
重视 ACEI 、 ARB 和 CCB 的治疗地位。
