Abstract

Introduction: Polymer-free sirolimus-eluting stent (PF-SES) possess multiple properties improving targeted drug elution and in-stent reendothelialization without the presence of polymers. The long-term clinical performance comparison between PF-SES and the latest generation polymer-coated sirolimus-eluting stents (SES), particularly regarding intravascular imaging assessment and in the type 2 diabetes mellitus (DM) population, remains unexplored.

Methods: We conducted a retrospective study involving 2646 diabetes patients meeting coronary artery disease (CAD) criteria underwent coronary stents in the real-world. All patients were divided into the PF-SES group and the SES group. Optical coherence tomography (OCT) was used to evaluate the imaging characteristics of in-stent reendothelialization. Patient information between the two groups was systematically compared in hospital and at 5-year follow-up.

Results: In terms of basic characteristics, the proportion of current smoker and stable angina patients in the PF-SES group was significantly higher than that in the SES group. The PF-SES group exhibited significantly higher rate of left anterior descending (LAD) lesion and more stents per patients compared to the SES group. The value of minimum lumen area (MLA), neointimal area (NA) and neointimal thickness (NT) were higher in the PF-SES group. Additionally, the occurrence rates of heterogeneous, lipid layer, intimal tears, thrombi, and micro-vessels were notably lower in the PF-SES group compared to the SES group. A higher all-cause mortality was observed in the SES cohort.

Discussion: PF-SES could effectively improve in-stent reendothelialization in patients with type 2 DM, with positive effects on survival rate and may, therefore, be considered as an alternative treatment option for improving clinical long-term outcomes.

2型糖尿病患者使用不含聚合物的西罗莫司洗脱支架和聚合物包覆的西罗莫司洗脱支架的长期临床疗效。
简介:不含聚合物的西罗莫司洗脱支架(PF-SES)具有多种特性,可在不含聚合物的情况下改善药物的靶向洗脱和支架内再内皮化。无聚合物西罗莫司洗脱支架(PF-SES)与最新一代聚合物涂层西罗莫司洗脱支架(SES)的长期临床性能比较,尤其是血管内成像评估和 2 型糖尿病(DM)人群中的临床性能比较,仍有待进一步研究:我们进行了一项回顾性研究,共有 2646 名符合冠状动脉疾病(CAD)标准的糖尿病患者在现实世界中接受了冠状动脉支架治疗。所有患者被分为 PF-SES 组和 SES 组。光学相干断层扫描(OCT)用于评估支架内再内皮化的成像特征。系统比较了两组患者在住院期间和5年随访期间的信息:就基本特征而言,PF-SES 组中吸烟者和稳定型心绞痛患者的比例明显高于 SES 组。与 SES 组相比,PF-SES 组的左前降支(LAD)病变率明显更高,患者人均支架数量也更多。PF-SES组的最小管腔面积(MLA)、新生内膜面积(NA)和新生内膜厚度(NT)值均较高。此外,与 SES 组相比,PF-SES 组异质性、脂质层、内膜撕裂、血栓和微血管的发生率明显较低。SES组的全因死亡率较高:讨论:PF-SES 可有效改善 2 型糖尿病患者支架内再内皮化,并对存活率产生积极影响,因此可作为改善临床长期预后的替代治疗方案。
