Clinical trials that evaluate more aggressive cholesterol reduction in a broader range of patients at high risk for coronary heart disease (CHD) are needed to fill gaps in our understanding of the impact of lipid-lowering therapy on risks for clinical events and mortality. This paper briefly reviews results from recent landmark studies that have evaluated the benefits of aggressive lipid-lowering therapy in patients with, or at risk for, CHD. The Reversing Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) study demonstrated that aggressive treatment with atorvastatin was significantly more effective than less aggressive therapy with pravastatin in slowing the progression of atherosclerosis in patients with symptomatic CHD. Results from two large-scale clinical end-point trials, the Heart Protection Study (HPS) and the Anglo-Scandinavian Cardiac Outcomes Trial-Lipid Lowering Arm (ASCOT-LLA), have shown that aggressive lipid-lowering treatment in patients with relatively low baseline levels of low-density lipoprotein cholesterol (LDL-C) significantly reduces CHD risk. Taken together, the results of these landmark trials not only support aggressive lipid lowering in patients at risk for CHD, but also suggest that greater LDL-C reductions may improve outcomes across a wide range of patients.
需要开展临床试验,在更广泛的冠心病(CHD)高危患者中评估更积极的胆固醇降低策略,以填补我们对降脂治疗对临床事件风险和死亡率影响的认识空白。本文简要回顾了近期一些具有里程碑意义的研究结果,这些研究评估了积极降脂治疗对冠心病患者或有冠心病风险患者的益处。积极降脂逆转动脉粥样硬化(REVERSAL)研究表明,在有症状的冠心病患者中,阿托伐他汀积极治疗在减缓动脉粥样硬化进展方面比普伐他汀的非积极治疗显著更有效。两项大型临床终点试验——心脏保护研究(HPS)和盎格鲁-斯堪的纳维亚心脏结局试验-降脂分支(ASCOT-LLA)的结果显示,在低密度脂蛋白胆固醇(LDL-C)基线水平相对较低的患者中,积极降脂治疗可显著降低冠心病风险。综合来看,这些具有里程碑意义的试验结果不仅支持对有冠心病风险的患者进行积极降脂治疗,还表明更大程度地降低LDL-C可能改善广泛患者群体的预后。
