Saphenous vein grafts (SVGs) have high rates of in-stent restenosis (ISR). We compared the baseline clinical and angiographic characteristics of patients and lesions that did develop ISR with those who did not develop ISR during a median follow-up of 2.7 years in the DIVA study (NCT01121224). We also examined the ISR types using the Mehran classification. ISR developed in 119 out of the 575 DIVA patients (21%), with similar incidence among patients with drug-eluting stents and bare-metal stents (BMS) (21% vs 21%, p = 0.957). Patients in the ISR group were younger (67 ± 7 vs 69 ± 8 years, p = 0.04) and less likely to have heart failure (27% vs 38%, p = 0.03) and SVG lesions with Thrombolysis In Myocardial Infarction 3 flow before the intervention (77% vs 83%, p <0.01), but had a higher number of target SVG lesions (1.33 ± 0.64 vs 1.16 ± 0.42, p <0.01), more stents implanted in the target SVG lesions (1.52 ± 0.80 vs 1.31 ± 0.66, p <0.01), and longer total stent length (31.37 ± 22.11 vs 25.64 ± 17.42 mm, p = 0.01). The incidence of diffuse ISR was similar in patients who received drug-eluting-stents and BMS (57% vs 54%, p = 0.94), but BMS patients were more likely to develop occlusive restenosis (17% vs 33%, p = 0.05).
大隐静脉移植血管(SVG)的支架内再狭窄(ISR)发生率很高。在DIVA研究(NCT01121224)中,我们比较了在中位随访2.7年期间发生ISR的患者和病变与未发生ISR的患者和病变的基线临床及血管造影特征。我们还使用梅兰分类法检查了ISR类型。DIVA研究的575例患者中有119例(21%)发生了ISR,药物洗脱支架和裸金属支架(BMS)患者的发生率相似(21%对21%,p = 0.957)。ISR组患者更年轻(67±7岁对69±8岁,p = 0.04),发生心力衰竭的可能性更小(27%对38%,p = 0.03),干预前心肌梗死溶栓3级血流的SVG病变更少(77%对83%,p<0.01),但目标SVG病变数量更多(1.33±0.64对1.16±0.42,p<0.01),目标SVG病变中植入的支架更多(1.52±0.80对1.31±0.66,p<0.01),总支架长度更长(31.37±22.11对25.64±17.42 mm,p = 0.01)。接受药物洗脱支架和BMS的患者弥漫性ISR发生率相似(57%对54%,p = 0.94),但BMS患者发生闭塞性再狭窄的可能性更大(17%对33%,p = 0.05)。
