Recently, a debate over the merits of statin therapy in primary prevention was published in the Wall Street Journal. The statin opponent claimed that statins should only be used in secondary prevention and never in any primary-prevention patients at risk for cardiovascular events. In this evidence-based rebuttal to those claims, we review the evidence supporting the efficacy of statin therapy in primary prevention. Cardiovascular risk is a continuum in which those at an elevated risk of events stand to benefit from early initiation of therapy. Statins should not be reserved until after a patient suffers the catastrophic consequences of atherosclerosis. Contrary to the assertions of the statin opponent, this principle has been demonstrated through reductions in heart attacks, strokes, and mortality in numerous randomized controlled primary-prevention statin trials. Furthermore, data show that once a patient tolerates the initial treatment period, the few side effects that subsequently emerge are largely reversible. Accordingly, every major guidelines committee endorses statin use in secondary prevention and selectively in primary prevention for those with risk factors. The foundation for prevention remains increased physical activity, better dietary habits, and smoking cessation. However, prevention of heart attacks, strokes, and death from cardiovascular disease does not have to be all or none-all statin or all lifestyle. In selected at-risk individuals, the combination of pharmacotherapy and lifestyle changes is more effective than either alone. Future investigation in prevention should focus on improving our ability to identify these at-risk individuals.
最近,《华尔街日报》发表了一篇关于他汀类药物在一级预防中的益处的争论。他汀类药物的反对者声称,他汀类药物仅应在二级预防中使用,而绝不应在有心血管事件风险的任何一级预防患者中使用。在这篇基于证据的反驳中,我们回顾了支持他汀类药物在一级预防中有效性的证据。心血管风险是一个连续体,那些处于事件高发风险的人将从早期开始治疗中获益。他汀类药物不应该等到患者遭受动脉粥样硬化的灾难性后果后再使用。与他汀类药物反对者的断言相反,这一原则已通过众多随机对照一级预防他汀类药物试验中降低心脏病发作、中风和死亡率得到证实。此外,数据表明,一旦患者耐受初始治疗期,随后出现的少数副作用在很大程度上是可逆的。因此,每个主要指南委员会都支持他汀类药物在二级预防中的使用,并根据危险因素选择性地在一级预防中使用。预防的基础仍然是增加身体活动、改善饮食习惯和戒烟。然而,预防心脏病发作、中风和死于心血管疾病不必非此即彼——要么全是他汀类药物,要么全是生活方式。在有风险的特定人群中,药物治疗和生活方式改变的结合比单独使用任何一种都更有效。未来的预防研究应侧重于提高我们识别这些高危人群的能力。
