目的评价同种药物洗脱支架和不同种药物洗脱支架治疗冠状动脉药物洗脱支架内再狭窄的有效性。方法计算机检索Pub Med、OVID、Embase、Cochrane图书馆、万方数据库、中国学术期刊全文数据库(CNKI)、中国生物医学文献数据库(CBM)、维普数据库(VIP),收集同种和不同种药物洗脱支架治疗冠状动脉药物洗脱支架内再狭窄的临床资料,共纳入10项研究,1680名患者,使用Rev Man5.2软件进行系统评价。检索时间为各大数据库建库至2015年10月。结果在治疗冠状动脉药物洗脱支架内再狭窄时,采用不同药物洗脱支架可降低靶病变血运重建率(OR=0.73,95%CI为0.55~0.96,P=0.02)和主要不良心血管事件发生率(OR=0.72,95%CI为0.54~0.96,P=0.03)。两组间的病死率(OR=1.03,95%CI为0.49~2.16,P=0.95)和心肌梗死发生率(OR=0.59,95%CI为0.24~1.41,P=0.23)无统计学差异。结论对于药物洗脱支架内再狭窄患者,再次植入不同药物洗脱支架比植入同种支架更获益。 相似文献

冠状动脉支架内血栓与药物洗脱支架的安全性 总被引:1,自引:0,他引:1
最近,药物洗脱支架的安全性问题引起了人们的广泛关注。目前资料表明药物洗脱支架与金属裸支架相比并不引起更多的早、晚期支架内血栓发生,但极晚期支架内血栓形成的风险增加。药物洗脱支架明显降低支架内再狭窄的发生和靶病变的再次血运重建率,其有效性仍优于金属裸支架,尤其对于糖尿病等再狭窄高危患者。根据患者的临床具体情况合理选择支架非常重要。现综述冠状动脉支架内血栓与药物洗脱支架安全性的研究进展。 相似文献

冠状动脉支架自问世已有30余年的历程,从金属裸支架(bare metal stent,BMS)到药物洗脱支架(drug eluting stent,DES),其在临床冠心病治疗中已经发挥了巨大作用。BMS的置入能够明显改善经皮冠状动脉腔内血管成形术后 相似文献

药物洗脱支架面临新的挑战 总被引:3,自引:0,他引:3
冠心病介入治疗(PCI)术后支架内再狭窄长期以来因绕着心脏介入医师,成为冠心病介入治疗后医师关注的焦点。虽然药物洗脱支架大大降低了支架内再狭窄发生率,减少PCI术后靶血管重建、主要心脏事件的发生,但最近的研究结果提示,与置入金属裸支架相比,置入药物洗脱支架增加晚期心肌梗死及死亡的发生。主要原因为晚期支架内血栓形成。在当今药物洗脱支架时代,是否所有的冠心病病人、是否所有冠状动脉病变类型都需要置入药物洗脱支架以及究竟什么病变、病人才能从药物洗脱支架中获益,将再次成为关注的焦点。 相似文献

药物洗脱支架与支架内再狭窄 总被引:4,自引:0,他引:4
随着药物洗脱支架(Drug Eluting Stent, DES)的出现,再狭窄的问题得到进一步的有效控制,目前的临床证据表明DES总的再狭窄率已经在10%以下.但DES的支架内再狭窄ISR仍是临床介入治疗面临的重要问题. 相似文献

冠状动脉支架现广泛应用于冠心病的介入治疗中。支架内血栓是金属裸支架和药物洗脱支架的一个并发症,可导致心肌梗死或死亡。最近,药物洗脱支架引起晚期支架内血栓的问题引起人们的广泛关注。支架血栓的危险因素包括操作因素(如支架贴壁不良、置入支架的数目、支架长度及夹层)、患者及病变因素、过早停用抗血小板药物以及支架释放的药物使内皮延迟愈合等。现对支架晚期血栓的概念、发生的危险因素、防治措施等进行探讨。 相似文献

药物洗脱支架(DES)的诞生和不断优化已经大大提高了经皮冠状动脉介入治疗(PCI)的安全性和有效性,但随着病例复杂性的增加和DES的超适应证应用,术后再狭窄率正逐年上升。因此,当前DES时代下,支架内再狭窄(ISR)仍是临床上亟待解决的一大难题。本文将主要就DES置入后ISR发生发展的病理机制、组织病理学及治疗策略的最新研究成果及进展进行综述。 相似文献

目的 比较雷公藤内酯醇洗脱支架与西罗莫司(sirolimus,雷帕霉素)洗脱支架预防冠状动脉支架植入术后再狭窄的作用.方法 选用杂种幼猪30只,随机分成裸支架组、雷公藤内酯醇洗脱支架组和西罗莫司洗脱支架组,每组各植入支架10枚.术后28 d,进行冠状动脉造影、组织病理检查以及免疫组化检测血管平滑肌细胞中增殖细胞核抗原(proliferating cell nuclear antigen,PCNA).结果 雷公藤内酯醇洗脱支架组与西罗莫司洗脱支架组支架内最小内径相似(P>0.05),均大于裸支架组(P<0.01);雷公藤内酯醇洗脱支架组新生内膜面积与西罗莫司洗脱支架组相似(P>0.05),均小于裸支架组(P<0.01).雷公藤内酯醇洗脱支架组与西罗莫司洗脱支架组的PCNA阳性细胞数相似(P>0.05),均少于裸支架组(P<0.01).结论 雷公藤内酯醇洗脱支架能抑制平滑肌细胞增殖,其预防冠状动脉支架内再狭窄的作用与西罗莫司洗脱支架相似. 相似文献

Coronary artery disease (CAD) is a cardiovascular disease of the blood vessels that makes vessels, narrow and hardened and difficult to supply blood to the heart. The epidemiology of CAD disease is a common clinical syndrome of a global health priority and the burden is increasing at an alarming rate worldwide. The prevalence of CAD not only increases mortality, morbidity and worsens the patient quality of life but also puts a huge burden on the overall healthcare system. The novel risk factors include: cholesterol level, cigarette smoking, diabetics, obesity, and hypertension, respectively are the causative agents of CAD. Furthermore, the etiology of CAD is also a very complex process and several interrelated etiological factors are involved in the pathogenesis of CAD. The signs and symptoms of CAD appear like angina, heart failure, and dyspnea, myocardial infarction, and arrhythmia, respectively. The management and diagnosis of CAD include different types of medications that are used nowadays for the treatment of this disease. The highlights of the present review focused on stent technology and its useful applications. Finally, we also addressed the benefits of the stent, and its potential complications, effectiveness, indication, and contraindication that play a significant role in the recovery of CAD disease. 相似文献

Between January 1995 and July 1998, percutaneous transluminal coronary angioplasty was performed on 27 lesions in 24 octogenarians. Half of the patients were African American. Women comprised 67% of the study group. Patients with unstable angina and myocardial infarction constituted 54% of the cohort. Two-thirds of the patients (83%) had single vessel disease with predominant class A and B lesion complexity of the angioplasty site. Acute success rate was 92%. Stents were successfully placed in 11 subjects (46%). None had acute myocardial infarction, emergency coronary artery bypass surgery, or stroke as a complication of the procedure. One patient presenting with acute myocardial infarction complicated by cardiogenic shock, died. Significant bleeding complications requiring blood transfusions occurred in 17% of patients. Of the patients, 23 (96%) were discharged in a clinically stable condition. Follow up during a two year period was completed in 21 patients (88%). One patient died of cancer. Four subjects (19%) underwent repeat percutaneous transluminal coronary angioplasty. One other patient had recurrent chest pain requiring multiple hospitalizations. The remaining 16 patients (76%) remained free of recurrence of angina. We concluded that percutaneous transluminal coronary angioplasty with stent placement can be performed in octogenarians with a high rate of clinical and angiographic success with an acceptable range of morbidity and mortality, and favorable long term (two year) outcome. 相似文献

This is the first reported use of the JOSTENT stent graft for aneurysm disease in native coronaries. Consideration can be given to using this polytetrafluoroethylene (PTFE)-covered stent in situations such as dissections and restenosis in saphenous vein grafts or in long native coronary arteries without side branches, though further investigation is warranted.
