  8月28日,在欧洲心脏病学会(ESC2011)临床研究更新会上,英国学者Peter S Sever报告了盎格鲁-斯堪的那维亚心脏终点研究降脂分支(ASCOT-LLA)终止后继续随访8年的结果。证实对于高血压患者,前期接受阿托伐他汀治疗能够产生长期益处。

  ASCOT-LLA研究因阿托伐他汀较安慰剂显著获益而在2003年提前终止,表现为包括冠心病(HR 0.64,CI 0.50-0.83,p=0.0005)和卒中(HR 0.73,CI 0.56-0.96,p=0.02)在内的多个心血管终点显著减少。心血管死亡(HR 0.90,CI 0.66-1.23,p=0.50)和全因死亡(HR 0.87,CI 0.71-1.06,p=0.16)减少,但不具有显著性。

  研究分析了ASCOT-LLA研究中止后7年英国受试者的死亡数据,共纳入4605例高血压患者。这些患者在ASCOT-LLA研究最初随机接受了阿托伐他汀10 mg或安慰剂治疗,平均随访时间是3.3年。

  结果显示,阿托伐他汀可使低密度脂蛋白胆固醇酯(LDL-C)降低1.1 mmol/L。在ASCOT-LLA试验终止时所有患者均接受了他汀治疗,而在该试验终止后随访2年时发现,约60%的患者正接受他汀治疗,同时无论患者前期接受阿托伐他汀或安慰剂治疗,其脂质水平均相当。至2010年(ASCOT-LLA完成后8年),共有980例全因死亡,其中460例前期接受了阿托伐他汀治疗,520例前期接受了安慰剂治疗(HR 0.86,CI 0.76-0.98,p=0.02)。前期接受阿托伐他汀或安慰剂治疗组的心血管死亡分别为154例和168例(HR 0.89,CI 0.72-1.11,p= 0.32)。

  因此,前期接受阿托伐他汀能够显著降低非心血管死亡(HR 0.85,CI 0.73-0.99,p=0.03),其原因或为显著降低了感染和(或)呼吸系统疾病死亡。此外,恶性肿瘤死亡没有差异。
