ACC/AHA胆固醇指南能更**和更有效识别适宜他汀治疗人群

2015-07-29 小田 译 医学论坛网

2013年美国心脏病学会和美国心脏学会(ACC /AHA)胆固醇治疗指南已阐述了他汀类药物新的适用原则,但这部指南是否能够改善那些心血管事件高风险成人的识别力尚不清楚。因此,美国学者近期对比了2004年美国胆固醇教育计划成人治疗组第三次更新版的胆固醇检评估和治疗指南(以下简称ATP III指南)与2013年ACC/AHA胆固醇治疗指南(以下简称ACC/AHA指南)对心血管事件高风险成人的识别力进行

2013年美国心脏病学会和美国心脏学会(ACC /AHA)胆固醇治疗指南已阐述了他汀类药物新的适用原则,但这部指南是否能够改善那些心血管事件高风险成人的识别力尚不清楚。因此,美国学者近期对比了2004年美国胆固醇教育计划成人治疗组第三次更新版的胆固醇检评估和治疗指南(以下简称ATP III指南)与2013年ACC/AHA胆固醇治疗指南(以下简称ACC/AHA指南)对心血管事件高风险成人的识别力进行了对比。结果表明,在基于社区的一级预防队列中,在确定他汀类药物适用性方面,与ATP III指南相比,ACC/AHA指南可更精确和更有效地识别CVD发生风险增加人群和亚临床冠状动脉疾病人群,尤其是在中危受试者中。相关研究近期在线发表于《美国医学会杂志》(简称JAMA)。

该基于社区的纵向队列研究纳入了弗明翰心脏研究(Framingham Heart Study)中的后代和第三代队列受试者,他们均在2002年至2005年间接受了冠状动脉钙化(CAC)的多层CT检查,并对其心血管发生率进行中位随访9.4年。根据ATP III推荐的弗明翰风险因素和低密度脂蛋白阈值确定他汀适用性,但用汇集队列计算器计算ACC/AHA指南的适用性。主要结局为包括心肌梗死和因冠状动脉性心脏病(CHD)所致的死亡或缺血性卒中的心血管疾病(CVD)发生率;次要结局为CHD和CAC。

结果显示,在2435例未用过他汀类药物的受试者(平均年龄51.3岁,女性56%)中,ACC/AHA指南和ATP III指南推荐的他汀适用比例分别为39%和14%(P<0.001);共发生了75例CVD事件,其中心肌梗死、致命性CHD事件和非致命性缺血性卒中分别为40例、3例和31例。

在他汀适用性方面,ACC/AHA指南和ATP III指南评估的受试者CVD事件危险比分别增加:3.1 vs.6.8(P<0.001)。在中间弗明翰风险评分的受试者中也可见到类似的CVD和CHD结果。

在新适用于他汀治疗的受试者(593例)中,CVD发生率为5.7%,需治疗比为39:58 。在两部指南的推荐下,伴CAC受试者更可能适用于他汀治疗的比例分别为以下数据,ACC/AHA指南vs.ATP III指南:CAC得分>0,63% vs 23%;CAC得分>100,80% vs 32%;CAC得分>300,85% vs 34%;所有P值均<0.001。CAC得分为0可识别ACC/AHA指南适宜他汀类药物治疗受试者中的低危人群,这类人群CVD发生率为1.6%。
