A cardiologist and respirologist examined the recent, neutral Prospective Randomized Placebo-Controlled Trial of Simvastatin in the Prevention of COPD Exacerbations (STATCOPE) for issues of relevance to cardiovascular risk reduction with statin medications. Although the potential benefit of the pleiotropic effects of statins on this inflammatory disease was not borne out, the effect over the longer term on total respiratory and cardiovascular morbidity and mortality remain unexplored. This study was unique as the only statin trial to date to use a national guideline (Adult Treatment Panel III) to exclude patients from the trial if at sufficient cardiovascular risk to warrant statin therapy. Furthermore, observed fatal and nonfatal cardiovascular events were shown to provide some evidence to suggest that statins might reduce cardiovascular events despite the low risk category and the relatively low levels of cholesterol. The magnitude of this beneficial trend paralleled the magnitude of lowering of low-density lipoprotein cholesterol achieved in the active statin arm. Finally, the authors questioned whether the current standard of care adequately includes adherence to any national lipid guideline or adequate attention to the cardiovascular comorbidity of these patients. In conclusion, knowledge translation of the STATCOPE trial should at a minimum encourage assessment of cardiovascular risk in patients with chronic obstructive pulmonary disease, implementation of proven cardiovascular risk reduction therapies based on national guidelines, including statins, and plans to undertake a trial adequate in size and duration to address cardiovascular event reduction in patients not already eligible for evidence-based risk-reducing therapies.
一位心脏病专家和呼吸病专家研究了最近的、中立的辛伐他汀预防 COPD 加重的前瞻性随机安慰剂对照试验(STATCOPE),以了解他汀类药物降低心血管风险的相关问题。尽管他汀类药物对这种炎症性疾病的多效作用的潜在益处没有得到证实,但长期来看,他汀类药物对总呼吸和心血管发病率和死亡率的影响仍未得到探索。这项研究是独特的,因为它是迄今为止唯一一项使用国家指南(成人治疗专家组 III)排除有足够心血管风险需要他汀类药物治疗的患者的他汀类药物试验。此外,观察到的致命和非致命心血管事件提供了一些证据,表明尽管属于低风险类别且胆固醇水平相对较低,他汀类药物可能会降低心血管事件。这种有益趋势的幅度与他汀类药物治疗组降低低密度脂蛋白胆固醇的幅度相吻合。最后,作者质疑当前的护理标准是否充分包括对慢性阻塞性肺疾病患者进行心血管风险评估,是否充分关注这些患者的心血管合并症,以及是否根据国家指南实施已证实的心血管风险降低治疗,包括他汀类药物治疗。总之,STATCOPE 试验的知识转化至少应鼓励评估慢性阻塞性肺疾病患者的心血管风险,根据国家指南实施已证实的心血管风险降低治疗,包括他汀类药物治疗,并计划进行足够大和足够长时间的试验,以减少已不符合循证风险降低治疗标准的患者的心血管事件。
