Atherosclerosis:ACS患者使用10mg阿托伐他汀足矣(CHILLAS研究)

2014-12-12 伊文 中国循环杂志

中国急性冠脉综合征(ACS)患者需要使用大剂量他汀强化降脂吗?由于之前国人的研究很少,中国的指南都是拿着国外的研究“照猫画虎”。而湘雅二院赵水平教授牵头的急性冠脉综合征患者强化降脂干预研究(CHILLAS)结果的正式公布,可以说是“几家欢乐,几家愁”了。 在这项研究中,常规他汀治疗的定义是10 mg/d阿托伐他汀或其他等效他汀,强化他汀治疗的定义是20或40 mg/d阿托伐他汀或其他等效

中国急性冠脉综合征ACS)患者需要使用大剂量他汀强化降脂吗?由于之前国人的研究很少,中国的指南都是拿着国外的研究“照猫画虎”。而湘雅二院赵水平教授牵头的急性冠脉综合征患者强化降脂干预研究(CHILLAS)结果的正式公布,可以说是“几家欢乐,几家愁”了。

在这项研究中,常规他汀治疗的定义是10 mg/d阿托伐他汀或其他等效他汀,强化他汀治疗的定义是20或40 mg/d阿托伐他汀或其他等效他汀。主要终点包括:心原性死亡、非致命性心梗、血管重建、缺血性脑卒中和因不稳定心绞痛、严重心力衰竭住院治疗。

在3个月时,常规组LDL-C降低了20.2%,强化组降低了26.6%。但是,尽管强化组多降低了6.4%的LDL-C。在2年随访时,常规他汀有3.9%发生终点事件,强化他汀组有5.5%的患者发生终点事件,二者没有统计学意义(图1)。两组患者的安全性良好,没有发生肌溶解症的患者。

研究中两组患者的高敏C反应蛋白(CRP)的下降也没有差别。

赵水平认为,强化他汀治疗多降低6.4%的LDL-C没有转化成临床获益。“针对中国人群的血脂特点,临床医生应谨慎使用高剂量他汀治疗。”因为,随着他汀剂量的增加,中国人群药物不良反应的发生是欧洲人群的5-10倍。

研究中入选患者的平均LDL-C仅有2.7 mmol/L (105 mg/dl),而此前西方类似的该研究中,LDL-C的水平达到了3.6 mmol/L(120-140 mg/dl)。赵水平指出,国外的研究表明,他汀对心脏事件降低取决于患者治疗前的LDL-C水平,当患者的LDL-C低到一定水平的时候,他汀的获益会减少,甚至消失。

正因为如此,“我们的研究2年随访时主要终点仅3.6%。这与当年用血脂康做的CCSPS研究的结论是一致的。”他说。

这项研究结果也再次支持了《ACC/AHA2013降低心血管风险临床实践指南》的推荐:亚裔人群使用高剂量他汀治疗需谨慎考量(Ⅰ类),也支持美国食品药品监督管理局(FDA)建议的亚裔人群以低剂量瑞舒伐他汀作为起始治疗的决定。

CHILLAS研究是一项开放的随机对照研究,共纳入1355例ACS患者,分别给予常规他汀治疗(675例)和强化他汀治疗(680例)。
