The usefulness of drug-eluting balloons (DEBs) has not been fully elucidated in calcified coronary lesions (CCLs). This meta-analysis aimed to evaluate the efficacy of DEBs compared to a drug-eluting stent (DES) in this setting. PubMed, EMBASE and Cochrane were searched through December 2023. The primary endpoint was 12 months major adverse cardiac events (MACE). Secondary endpoints included clinical outcomes and angiographic results after PCI and at a 12-month follow-up. Five studies and a total of 1141 patients with 1176 coronary lesions were included. Overall, the DEB was comparable to DES in MACE (RR = 0.86, 95% CI: 0.62-1.19, = 0.36), cardiac death (RR = 0.59, 95% CI: 0.23-1.53, = 0.28), myocardial infarction (RR = 0.89, 95% CI: 0.25-3.24, = 0.87) and target lesion revascularization (RR = 1.1, 95% CI: 0.68-1.77, = 0.70). Although the DEB was associated with worse acute angiographic outcomes (acute gain; MD = -0.65, 95% CI: -0.73, -0.56 and minimal lumen diameter; MD = -0.75, 95% CI: -0.89, -0.61), it showed better results at 12 months follow-up (late lumen loss; MD = -0.34, 95% CI: -0.62, -0.07). This meta-analysis showed that the DEB strategy is comparable to DES in the treatment of CCLs in terms of clinical outcomes. Although the DEB strategy had inferior acute angiographic results, it may offer better angiographic results at follow-up.
药物洗脱球囊(DEB)在钙化冠状动脉病变(CCL)中的应用价值尚未完全阐明。本荟萃分析旨在评估在这种情况下,DEB与药物洗脱支架(DES)相比的疗效。检索了截至2023年12月的PubMed、EMBASE和Cochrane数据库。主要终点是12个月时的主要不良心脏事件(MACE)。次要终点包括PCI后及12个月随访时的临床结局和血管造影结果。纳入了5项研究,共1141例患者,1176处冠状动脉病变。总体而言,DEB在MACE(风险比[RR]=0.86,9�%置信区间[CI]:0.62-1.19,P=0.36)、心源性死亡(RR=0.59,95%CI:0.23-1.53,P=0.28)、心肌梗死(RR=0.89,95%CI:0.25-3.24,P=0.87)和靶病变血运重建(RR=1.1,95%CI:0.68-1.77,P=0.70)方面与DES相当。尽管DEB与较差的急性血管造影结局相关(急性增益;平均差[MD]=-0.65,95%CI:-0.73,-0.56;最小管腔直径;MD=-0.75,95%CI:-0.89,-0.61),但在12个月随访时显示出更好的结果(晚期管腔丢失;MD=-0.34,95%CI:-0.62,-0.07)。本荟萃分析表明,在治疗CCL方面,DEB策略在临床结局方面与DES相当。尽管DEB策略的急性血管造影结果较差,但在随访时可能提供更好的血管造影结果。
