摘要:

文题释义:
支架内再狭窄:是指支架内全程和/或支架两端5 mm节段内管腔丢失,导致管腔狭窄程度≥50%;临床定义为冠状动脉支架植入后需要靶病变或靶血管血运重建的症状性再狭窄,临床表现为缺血性胸痛,如心绞痛或急性心肌梗死等。
药物洗脱球囊:通过向冠状动脉血管壁释放抗增殖药物(紫杉醇),抑制血管内膜增生,适用于小血管疾病、分叉疾病和支架内再狭窄病变、支架内再狭窄,优点在于无异物植入,降低了血栓形成风险,减少了再狭窄的发生,后续抗血小板治疗时间较短。

背景:国内外一系列的研究显示针对药物洗脱支架内再狭窄病变,药物洗脱球囊和药物洗脱支架优于其他介入方式,但是这两种治疗方式都存在着各自的局限。

目的:评价药物洗脱球囊与药物洗脱支架植入治疗药物洗脱支架内再狭窄的疗效。

方法:选择2016年1月至2017年12月内蒙古医科大学第一附属医院收治的药物洗脱支架内再狭窄患者63例,其中32例进行药物洗脱球囊植入治疗,另31例进行药物洗脱支架植入治疗,记录两组患者介入术前、术后即刻冠状动脉情况,随访1 年后冠状动脉造影情况、主要不良心血管事件发生及支架内再狭窄的危险因素分析。研究得到内蒙古医科大学伦理委员会的同意及支持。

结果与结论:①随访1年,两组支架内最小管腔直径、参考血管直径、支架内晚期管腔丢失比较差异均无显著性意义(P均> 0.05),二次再狭窄概率比较差异无显著性意义(18%,16%,P=0.216)。靶病变血运重建发生率比较差异无显著性意义(6%,6%,P=0.513),主要不良心脏事件发生率比较差异无显著性意义(9%,10%,P=0.334);药物洗脱支架组2例发生消化道出血,药物洗脱球囊组未发生消化道出血,两组比较差异有显著性意义(P < 0.01);②多因素分析发现,吸烟、糖尿病、高同型半胱氨酸血症是支架内再狭窄的危险因素;③结果表明,药物洗脱球囊与药物洗脱支架均是治疗支架内再狭窄的理想方法,临床实践中需综合多因素考虑需采取个体化治疗方案。

Abstract:

BACKGROUND: A series of studies have shown that both drug-eluting balloons and drug-eluting stents are better than the other treatments for drug-eluting in-stent restenosis lesions, but both of them have limitations.

OBJECTIVE: To evaluate the long-term therapeutic efficacy of drug-eluting balloons and drug-eluting stents in the treatment of coronary in-stent restenosis.

METHODS: A total of 63 patients with in-stent restenosis who received treatment in the First Affiliated Hospital of Inner Mongolia Medical University between January 2016 and December 2017 were included in this study. Among these patients, 32 patients received treatment with drug-eluting balloons (drug-eluting balloon group) and 31 patients were treated with drug-eluting stents (drug-eluting stent group). Coronary artery status before and immediately after surgery, coronary angiography 1 year after surgery, adverse events, and the risk factors of in-stent restenosis were recorded in both groups. The study was approved and supported by the Medical Ethics Committee of Inner Mongolia Medical University. 

RESULTS AND CONCLUSION: All patients were followed up for 1 year. There were no significant differences in minimum in-stent diameter, target vessel diameter, in-stent lumen loss in the late period between patients receiving treatment with drug-eluting balloons and patients receiving drug-eluting stents (all P > 0.05). There were no significant differences in secondary restenosis rate (18% vs.16%, P=0.216), target lesion revascularization rate (6% vs. 6%, P=0.513), and incidence of adverse events (9% vs.10%, P=0.334) between drug-eluting balloon and drug-eluting stent groups. There were two cases of gastrointestinal bleeding in the drug-eluting stent group, and no gastrointestinal bleeding occurred in the drug-eluting balloon group. Significant difference in gastrointestinal bleeding occurred between these two groups (P < 0.01). Multi-factor analysis showed that smoking, diabetes and hyperhomocysteinemia are the risk factors of in-stent restenosis. These results suggest that both drug-eluting balloons and drug-eluting stents are the ideal treatments of in-stent restenosis. In clinical practice, individualized treatment options should be considered based on multiple factors.

Key words: drug-eluting stents, drug-eluting balloon, in-stent restenosis, percutaneous coronary intervention, coronary atherosclerotic heart disease, hyperhomocysteinemia, smoking, diabetes mellitus
