BMJ:生活方式干预不能改善缺血性心脏病预后

尽管如此,有关危险因素干预方式的研究尚需完善。因此,T Jørgensen教授研究团队在人群水平上评估了系统筛查缺血性心脏病风险因素的实际作用,具体方式为多次生活方式指导对10年缺血性心脏病进展的影响。研究结果发表于British Medical Journal杂志。

研究为以社区为基础的随机对照试验,共入组59616例丹麦哥本哈根30至60岁患者。随机分为干预组与对照组。干预组患者每5年接受4次筛检、风险评估及生活方式指导。不健康生活方式的患者在每次随访会接受量身定制的生活方式咨询。

如果患者有较高的风险罹患缺血性心脏病,研究者会进一步给予患者有关戒烟、节食及锻炼的生活方式咨询。5年后如果需要的话患者会转诊接受临床治疗。研究主要预后指标为两组的缺血性心脏病发生率,次要指标为卒中、复合事件及死亡率。

研究结果显示,无论主要终点事件还是次要终点事件,10年随访期间两组均无差异。研究者认为为期5年筛查缺血性心脏病危险因素及生活方式咨询并不能改善缺血性心脏病及卒中发病率,也不能影响死亡率。
