Most drug-eluting stent (DES) trials have excluded patients with chronic kidney disease (CKD). The efficacy of DES implantation in patients with CKD is therefore not known.
To evaluate the outcomes with DES vs bare-metal stent (BMS) implantation in patients with CKD.
MEDLINE, EMBASE, and CENTRAL were searched for studies including at least 100 patients with CKD (estimated glomerular filtration rate ≤60 mL/min/1.73 m² or on dialysis) treated with DES or BMS and followed for at least 1 month and reporting outcomes of all-cause mortality, cardiovascular (CV) mortality, myocardial infarction (MI), target-vessel revascularization (TVR), and stent thrombosis (ST). Thirty-one studies (5 randomized) with 91,817 participants (49,081 DES and 42,736 BMS) fulfilled the inclusion criteria. DES was associated with lower all-cause mortality (relative risk [RR], 0.77; 95% confidence interval [CI], 0.71-0.84), CV mortality (RR, 0.51; 95% CI, 0.38-0.70), MI (RR, 0.90; 95% CI, 0.86-0.95), TVR (RR, 0.61; 95% CI, 0.47-0.80), and numerically lower ST (RR, 0.75; 95% CI, 0.55-1.01) when compared with BMS. Analysis by study type (RCTs vs non-RCTs) showed similar results for most outcomes (Pinteraction>.05) except all-cause mortality, where there was no difference between DES vs BMS in RCTs (Pinteraction=.04). The effects were greater with 2nd-generation DES vs BMS (for example, ST: RR, 0.38; 95% CI, 0.20-0.72).
In patients with CKD, the available evidence, largely from observational studies, suggests significantly fewer events with DES vs BMS with even a lower ST rate with 2nd-generation DES. These findings should be tested in large, randomized trials.
大多数药物洗脱支架(DES)试验排除了慢性肾脏病(CKD)患者。因此,DES植入在CKD患者中的疗效尚不清楚。
评估CKD患者植入DES与裸金属支架(BMS)的结局。
检索MEDLINE、EMBASE和CENTRAL数据库,查找纳入至少100例CKD患者(估计肾小球滤过率≤60 mL/min/1.73 m²或正在接受透析)并接受DES或BMS治疗、随访至少1个月且报告全因死亡率、心血管(CV)死亡率、心肌梗死(MI)、靶血管血运重建(TVR)和支架血栓形成(ST)结局的研究。31项研究(5项随机对照试验)共91,817名参与者(49,081例DES和42,736例BMS)符合纳入标准。与BMS相比,DES与较低的全因死亡率(相对风险[RR],0.77;95%置信区间[CI],0.71 - 0.84)、CV死亡率(RR,0.51;95% CI,0.38 - 0.70)、MI(RR,0.90;95% CI,0.86 - 0.95)、TVR(RR,0.61;95% CI,0.47 - 0.80)以及数值上较低的ST(RR,0.75;95% CI,0.55 - 1.01)相关。按研究类型(随机对照试验与非随机对照试验)分析显示,除全因死亡率外,大多数结局的结果相似(交互作用P>.05),在随机对照试验中DES与BMS的全因死亡率无差异(交互作用P = 0.04)。第二代DES与BMS相比效果更佳(例如,ST:RR,0.38;95% CI,0.20 - 0.72)。
在CKD患者中,现有证据大多来自观察性研究,表明与BMS相比,DES发生的事件显著减少,第二代DES的ST发生率更低。这些发现应在大型随机试验中进行验证。
