1、最新高血压指南的几个问题,刘力生,内容提要,关于血压水平的定义和分类关于危险度分层关于卫生经济学关于用药问题,高血压患者危险分层-WHO/ISH 1999,注:1999年中国高血压防治指南的危险分层参考的是 1999年WHO/ISH指南,影响高血压患者预后的因素,高血压患者危险分层-2003欧洲高血压指南,:平均危险;:低度危险增加;:中度危险增加;:高度危险增加;:极高度危险增加,Risk factor similar as 1999 guidelines except :1.abdominal obesity 2.Diabetes as a separate criterion 3.CRP

9、R 的重要指标,故以往只看血压水平决定治疗策略。此法对中重度高血压行之有效,对轻度高血压则否,心血管危险度分层的重要性(二),NHANES-I根据 JNC VI,对7,090NHEFS队列20年随访说明临床决策不仅依靠平均血压水平,并需考虑其他危险因素 1999年医院门诊人群高血压抽样调查报告表明,对门诊高血压患者的危险度评估中,如果只注意血压水平,是很不够的,会明显低估危险度,必须全面评估其他危险因素,才能作出正确的判断.,Problems With a Strategy Based on Absolute Cardiovascular RiskF.
