CCC 2014:全新加拿大心衰指南为ARNI创造空间

2014-11-06 伊文 国际循环

新的加拿大心力衰竭(心衰)患者管理指南已经更新,首次包含关于新的血管紧张素受体-脑啡肽酶抑制剂(ARNI)的使用推荐,这一新药在PARADIGM-HF研究中展露光芒。 新指南共同主席、多伦多圣米高医院Gordon Moe博士讲到,PARADIGM-HF研究中的数据效力非常强,他们认为应该在指南中进行推荐。Moe指出,“这项研究规模非常大,不会再有另一项研究能改变这种结果……这些都是数据,

新的加拿大心力衰竭(心衰)患者管理指南已经更新,首次包含关于新的血管紧张素受体-脑啡肽酶抑制剂ARNI)的使用推荐,这一新药在PARADIGM-HF研究中展露光芒。

新指南共同主席、多伦多圣米高医院Gordon Moe博士讲到,PARADIGM-HF研究中的数据效力非常强,他们认为应该在指南中进行推荐。Moe指出,“这项研究规模非常大,不会再有另一项研究能改变这种结果……这些都是数据,我们希望加入这一行动中,并作出推荐。但这只是一项有条件的建议,因为这种药物尚未被批准,而且不知道价格如何。”

这部新的心衰指南在上周于温哥华召开的2014加拿大心血管学会大会(CCC)上展示,并将于1月份发布。PARADIGM-HF研究结果首次在巴塞罗那召开的欧洲心脏病学学会年会上公布,心衰专家对ARNI的前景抱有极大热情,有些人认为它代表了未来慢性心衰治疗的基石药物。该研究已发布在New England Journal of Medicine。2个月后,这部新的加拿大指南就作出相应推荐。

在PARADIGM-HF研究中,使用命名为LCZ696(包含缬沙坦和脑啡肽酶抑制剂sacubitril的基团)的药物治疗2~3年的患者,与使用依那普利和其他基于证据的治疗相比,表现为显著更好的心血管死亡或心衰住院改善。使用新药而非ACEI的NYHA Ⅱ~Ⅳ级患者,不管是以上两种终点的总体风险还是单独风险,大约均下降20%。LCZ696组全因死亡减少16%。

指南共同主席、阿尔伯塔大学Justin Ezekowitz博士指出,他们对LCZ696作出推荐的原因是“相信通过对重要科学信息的有效转化和评估,有助于临床医生和其他卫生保健人员治疗患者时能作出更积极推荐。”另外,他们希望能通过强大的科学帮助监管部门(如加拿大卫生部)作出决策,使患者能得到最佳治疗选择。

除了新的ARNI,加拿大心衰指南也对贫血患者管理给予推荐,并指导生物标志物的使用。Moe指出,加拿大医生和其他卫生保健提供者表达了他们对这些领域的指导需求,尤其对于贫血。推荐有铁缺乏病史者应予以治疗,包括静脉补铁。不推荐促红细胞生成素制剂常规用于治疗伴有心衰的铁缺乏患者,因为这种制剂可增加血栓形成风险。加拿大指南也关注利钠肽在预防、诊断、疾病监测和出院情况时的使用。Ezekowitz讲到,指南支持使用这些生物标志物,希望能有更多医生使用以指导治疗。
