JAMA:仅需2周,阿利珠单抗在目前治疗基础上明显改善急性心肌梗死患者斑块负荷!

2022-04-05 网络 网络

冠状动脉斑块容易破裂并导致不良心脏事件的的特点是斑块负担大、脂质含量大、纤维帽薄。

冠状动脉斑块容易破裂并导致不良心脏事件的的特点是斑块负担大、脂质含量大、纤维帽薄。他汀类药物可以阻止冠状动脉粥样硬化的进展;然而,在他汀类药物治疗的基础上加入PSK-9抑制剂阿利珠单抗对斑块负担和组成的影响在很大程度上还是未知的。

为了利用急性心肌梗死患者的连续多模态冠状动脉内成像,确定阿利珠单抗对冠状动脉硬化的影响,来自瑞士伯尔尼大学医院心脏病科的专家开展了相关研究,结果表现在JAMA杂志上。

PACMAN-AMI双盲、安慰剂对照、随机临床试验在欧洲9家学术医院招募了300名接受经皮冠状动脉介入治疗PCI的急性心肌梗死患者,患者随机接受两周一次的皮下注射阿利珠单抗(150mg;n = 148)或安慰剂(n = 152),在紧急PCI病变后不到24小时开始,在高强度的他汀类药物治疗(瑞舒伐他汀,20mg)的基础上进行52周。

主要疗效终点是IVUS得出的动脉瘤体积百分比从基线到52周的变化。两个次要终点是:从基线到第52周,近红外光谱仪得出的4mm内最大脂质核心负担指数的变化和光学相干断层扫描得出的最小纤维帽厚度(数值越小表明斑块越薄越脆弱)。

在300名随机患者中(平均[SD]年龄,58.5[9.7]岁;56[18.7%]名女性;平均[SD]LDL-C水平,152.4[33.8]mg/dL),265名(88.3%)接受了537条动脉的连续IVUS成像。52周时,使用阿利珠单抗的动脉粥样斑块百分比体积的平均变化为-2.13%,而使用安慰剂的变化为-0.92%(差异=-1.21%[95%CI,-1.78%至-0.65%])。

在高强度他汀治疗的基础上使用阿利珠单抗的患者OCT结果

使用阿利珠单抗时,4mm内最大脂质核心负担指数的平均变化为-79.42,而使用安慰剂时为-37.60(差异=-41.24[95% CI,-70.71至-11.77])。使用阿利珠单抗的最小纤维帽厚度的平均变化为62.67μm,而使用安慰剂的变化为33.19μm(差异=29.65μm[95%CI,11.75-47.55])。

在急性心肌梗死患者中,与安慰剂相比,在高强度他汀治疗的基础上增加皮下双周的阿丽珠单抗,52周后,非梗死相关动脉的冠状斑块消退率明显提高。
