ACC 2014:GAUSS-2研究:evolocumab或可用于他汀不耐受患者

2014-03-31 小田 译 医学论坛网

PCSK9单克隆抗体evolocumab在本次美国心脏病学会年会(ACC2014)上可谓是风头正猛,如29日报道的多中心RUTHERFORD-2研究、MENDEL-2研究和DESCARTES研究结果均为阳性。30日有关evolocumab的研究又闪亮登场,这项研究表明,在他汀类药物不耐受的高胆固醇血症高危人群的治疗方面,evolocumab是一种前景比较好的联合治疗方法。研究论文3月30日在线发表

PCSK9单克隆抗体evolocumab在本次美国心脏病学会年会(ACC2014)上可谓是风头正猛,如29日报道的多中心RUTHERFORD-2研究、MENDEL-2研究和DESCARTES研究结果均为阳性。30日有关evolocumab的研究又闪亮登场,这项研究表明,在他汀类药物不耐受的高胆固醇血症高危人群的治疗方面,evolocumab是一种前景比较好的联合治疗方法。研究论文3月30日在线发表于《美国心脏病学杂志》(J Am Coll Cardiol)。

GAUSS-2是一项为期12周的双盲试验,旨在评估他汀类药物不耐受患者应用PCSK9单克隆抗体的效果,研究者随机将患者以2:2:1:1的比例分为evolocumab 140 mg [2周一次(Q2W)]或evolocumab 420 mg[每月一次(QM)],两组均同时给予安慰剂(PBO)口服; 或皮下注射PBO (Q2W或QM),两组均给予依折麦布10 mg口服。主要终点为患者基线低密度脂蛋白胆固醇(LDL-C)至12周和平均10周、12周的变化。

结果显示,共307例患者(平均年龄为62岁,平均LDL-C为193 mg/dl)纳入随机化研究。Evolocumab对LDL-C水平的降幅为53-56%,相对依折麦布的治疗差异为37-39% (P < 0.001)。evolocumab治疗组和依折麦布治疗组患者肌肉不良事件发生率分别为12%和23%。各治疗组出现紧急治疗不良事件和实验室异常均相当。

evolocumab将会对其余两种降脂药(他汀类药物和依折麦布)有何影响?让我们拭目以待!

“降压10原则”与“他汀6原则”带给我们的思考

高血压与高血脂治疗主要以药物治疗为主,但怎样规范、有效进行药物治疗是我们长期思考及探索的一个课题。但降压药物和降脂药物的作用是有限的。不管是何种降压药物,每一种药物的降压效果只是10/5mmHg;每降低6%的LDL-C,就需要将他汀类药物的剂量加倍,这就是“降压药物10原则”及“他汀药物6原则”,那么,“降压10原则”及“他汀6原则”带给我们怎样的思考呢? 1 “降压10原则”带来的思考 “血

IAS:non-HDL-C作为降脂治疗靶标更优

降脂:不能服用他汀的患者LDL如何达标?

降脂达标已成为防治动脉粥样硬化性心血管疾病的核心策略,而他汀类药物被视为血脂异常和抗动脉粥样硬化药物治疗的基石。然而,中国第二次血脂治疗现状调查结果显示,采用他汀稳定剂量治疗的高胆固醇血症患者胆固醇水平达标率低,尤为严重的是高危、极高危患者的达标率仅为39%和23%.究其原因,许多患者在接受较大剂量他汀治疗后其胆固醇水平仍不能达到目标值以下,另有一些患者由于种种原因(肝功能
