JACC:双降脂策略治疗PCI患者疗效更优

尽管使用标准的他汀类药物治疗,但大多数患者仍有较高的心血管事件的“残余风险”。
    
这项研究的目的是评价依折麦布+阿托伐他汀治疗与阿托伐他汀单独治疗,对日本的接受过经皮冠状动脉介入治疗(PCI)的患者的血脂和冠状动脉粥样硬化治疗的效果。
    
这项试验是一项前瞻性、随机、对照、多中心临床研究。接受PCI的符合条件的患者被随机分配接受单独阿托伐他汀治疗或每日阿托伐他汀加依折麦布(10mg)治疗。阿托伐他汀剂量是随着低密度脂蛋白胆固醇(LDL-C)<70毫克/分升的治疗目标而递增的。在基线以及9至12个月时,对202例患者进行两次连续的血管内超声,以量化患者的冠状动脉斑块反应。
    
阿托伐他汀/依折麦布的组合导致的LDL-C的水平低于阿托伐他汀单一疗法(63.2±16.3毫克/分升 vs 73.3±20.3毫克/分升;P<0.001)。对于粥样斑块体积百分比的绝对变化(PAV),2组之间的平均差异(-1.538%;95%的置信区间[Cl]:-3.079%〜0.003%)没有超过预先定义的非劣性范围的3%,但PAV的绝对变化确实表现出双降脂策略的优势(-1.4%;95%Cl:-3.4%〜-0.1% vs -0.3%;95%Cl:-1.9%〜0.9%阿托伐他汀单独治疗;P=0.001)。对于PAV,接受阿托伐他汀/依折麦布的患者显示出更大百分比的冠状动脉斑块消退现象(78% vs 58%;P=0.004)。这两种策略都具有可接受的副作用,例如实验室检查异常和心血管事件的发生率都较低。
    
与标准的他汀药物单一疗法相比,他汀类药物加上依折麦布的组合表现出更大的冠状动脉斑块消退结果,这可能是由于胆固醇吸收抑制-诱导的强化降脂。
