Lancet子刊:晚期肾脏疾病患者应怎样选择他汀类药物治疗方案?

2016-07-29 fsy 译 MedSci原创

他汀类药物治疗对轻、中度慢性肾脏病患者的冠心病和卒中的预防是有效的,但它对于一些晚期疾病患者(特别是那些接受透析的患者)的影响还是不确定的。研究人员做了个别参与者(n=183419)的荟萃分析,数据来自28个试验,该研究分析了基于他汀类药物治疗对重大血管事件(主要冠状动脉事件[非致死性心肌梗死或冠心病死亡],卒中或冠心病血运重建)和具体死因死亡率的效果。参与者通过基线估计肾小球滤过率(eGFR)被

他汀类药物治疗对轻、中度慢性肾脏病患者的冠心病和卒中的预防是有效的,但它对于一些晚期疾病患者(特别是那些接受透析的患者)的影响还是不确定的。

研究人员做了个别参与者(n=183419)的荟萃分析,数据来自28个试验,该研究分析了基于他汀类药物治疗对重大血管事件(主要冠状动脉事件[非致死性心肌梗死或冠心病死亡],卒中或冠心病血运重建)和具体死因死亡率的效果。参与者通过基线估计肾小球滤过率(eGFR)被分为几个类别。治疗效果通过LDL胆固醇每mmol/L的下降率比(RR)进行评估。

总体而言,基于他汀类药物治疗,每降低1 mmol/L的LDL胆固醇,第一大主要血管事件的风险降低21%(RR 0.79,95%CI 0.77-0.81,P<0.0001)。eGFR下降对于主要血管事件有较小的相对影响(趋势p=0.008; 在接受透析的患者中,对于eGFR≥60mL/(min·1.73m2时,RR 0.78,99%CI为0.75-0.82;对于eGFR为45至<60mL/(min·1.73m2时RR为0.76,0.70-0.81;对于eGFR为30至<45mL/(min·1.73m2时RR为0.85,0.75-0.96;对于eGFR<30mL/(min·1.73m2且不进行透析时,RR为0.85,0.71-1.02;透析的患者为0.94,0.79-1.11)。通过基线肾功能分类,主要冠状动脉事件(趋势P=0.01)和血管死亡事件(趋势P=0.03)的发生有类似的趋势,但是冠状动脉血运重建事件无显著趋势(P=0.90)。在不考虑eGFR的情况下,基于他汀类药物降低LDL胆固醇的治疗对非血管死亡率没有影响。

研究发现晚期慢性肾脏病患者的LDL胆固醇实现少量的降低;而且允许不同的透析试验中的结果在定义上有差异后,eGFR下降后,则基于他汀类药物治疗对于主要血管事件的相对减少量也会随之变小。在慢性肾脏疾病患者中,应选择绝对减少LDL胆固醇最大化的他汀类药物治疗方案,来实现最大治疗益处。
