ASH/ISH与JNC8高血压指南存在关键性差异

据Heartwire 12月19日报道,就在美国《2014成人高血压管理指南》(JNC 8)发布前一天,美国高血压学会/国际高血压学会(ASH/ISH)公布了以社区高血压管理为重点的临床实践指南。尽管两项指南存在共鸣,但亦具有数项关键性差异。 ASH/ISH指南概括了高血压流行病学、病因、评估、诊断、定义和分类等,并特设了黑人患者具体问题的专门章节。对于高血压的诊断以

据Heartwire 12月19日报道,就在美国《2014成人高血压管理指南》(JNC 8)发布前一天,美国高血压学会/国际高血压学会(ASH/ISH)公布了以社区高血压管理为重点的临床实践指南。尽管两项指南存在共鸣,但亦具有数项关键性差异

ASH/ISH指南概括了高血压流行病学、病因、评估、诊断、定义和分类等,并特设了黑人患者具体问题的专门章节。对于高血压的诊断以及60岁以上重点人群组的靶目标,两项指南应用了不同的标准。此外,指南还为高血压患者的检测和评估提供了详细指导,并专设了顽固性高血压的章节。

在包括糖尿病和慢性肾脏病在内的特定人群中,JNC 8和ASH/ISH指南均提出更为宽松的方案,但二者在其他方面存在分歧。ASH/ISH指南将≥150/90 mm Hg的治疗启动阈值应用于80岁以上患者,JNC  8则将上述阈值应用于60岁以上患者。根据患者不同的种族、年龄和血压水平,ASH/ISH指南推荐的降压起始治疗有异于JNC8。例如,JNC8认为血管紧张素转换酶抑制剂(ACEI)、血管紧张素受体拮抗剂(ARB)、钙拮抗剂(CCB)或噻嗪类利尿剂均为非黑人患者的合理可选起始药物,但 ASH/ISH指南则推荐在60岁以下非黑人患者中首选ACEI或ARB,在60岁以上非黑人患者中首选CCB或噻嗪类利尿剂。

ASH主席White博士在答复Heartwire记者的邮件中称,因为JNC 8指南制定遵循非常严格的循证证据,而只有少数几个安慰剂对照研究(SHEP和SystEUR)评估了60岁以上高血压人群的收缩压,评估80岁以上人的安慰剂对照研究则只有一个(HYVET),因此,JNC 8专家组认为由于缺乏证据说明<140 mmHg比<150 mmHg更能保护患者免于伤害,他们不能为60岁以上的人群推荐更低的阈值;而ASH/ISH专家组考虑,ALLHAT、ACCOMPLISH以及 VALUE研究纳入了许多60~80岁的患者并且治疗的指导目标是<140 mmHg,80岁以上患者的数据唯一来自于HYVET,该研究启动降压治疗时的血压为≥160 mmHg且治疗组的收缩压达到了146 mmHg,因此,他们推荐<150 mmHg应仅针对80岁以上的患者。
