残余Syntax评分对左主干病变经皮冠脉介入 治疗患者预后的影响

目的：探讨残余SYNTAX评分（residual SYNTAX score,rSS）对左主干病变（Left main,LM）接受PCI的患者远期预后的影响。方法：回顾性分析我院接受LM病变PCI治疗的患者,收集其临床资料、实验室检查、冠脉造影及介入操作资料,并计算其基线SYNTAX评分（baseline SYNTAX score,bSS）和rSS,根据rSS分值进行分为rSS＜8、rSS≥8两组,所有患者接受3年随访。结果：高rSS组患者左主干+三支病变比例更高,LM钙化比例更高,LVEF更低、肌酐清除率更低、操作并发症发生率及IABP支持比例更高,预后方面,高rSS与更高的心源性死亡（1.13% vs. 0.51%,p=0.0458）、支架内血栓（2.36% vs. 1.35%,p=0.0440）、所有血运重建（12.43% vs. 8.09%,p=0.0002）、全因死亡+所有心肌梗死+所有的血运重建复合终点（19.11% vs.13.29%,p<0.0001）、心源性死亡+靶血管相关心肌梗死+靶血管血运重建的复合终点（4.28% vs. 2.78%,p=0.0286）发生率相关。回归分析表明,rSS≥8分、年龄、左室射血分数是全因死亡+所有心肌梗死+所有的血运重建复合终点发生的独立危险因素。结论：在接受LM介入治疗的患者人群,较高的残余SYNTAX评分是3年复合终点发生的独立危险因素。

Iatrogenic left main coronary artery thrombosis during percutaneous coronary intervention

During diagnostic angiographic procedures or percutaneous coronary angioplasty-stenting of the other coronary arteries, the overall risk for a complication related to the left main coronary artery (LMCA) is low; however, if such complications occur, they tend to be life-threatening and contribute to a large part of the total catheter-related mortality. We encountered a case of iatrogenic significant subtotal left main coronary artery thrombotic stenosis in a patient who had undergone prior percutaneous transluminal coronary artery angioplasty-stenting of the left circumflex artery. In light of the literature, an extremely rare clinical presentation of iatrogenic left main coronary artery thrombosis is discussed.     

左主干及三支病变经皮冠状动脉介入与冠状动脉搭桥术后 随访对比研究

［摘要］目的：总结比较冠心病（左主干和三支病变）患者接受经皮冠状动脉介入（PCI）或冠状动脉旁路移植术（CABG或者OPCAB）后的治疗效果。方法：回顾性连续分析我院2009年9月到2012年9月期间行PCI或者CABG的左主干及三支病变患者,比较分析在住院期间、出院后12个月出院后终末事件,包括死亡、心肌梗死、脑血管事件、心绞痛复发和再次介入。结果：总共有1292名患者被纳入,分PCI组626名,CABG组666名;随访12个月,90％的PCI和97％的CABG患者纳入。死亡、心肌梗死或中风在CABG患者中都较PCI患者低（P =0.01）。结论：在三支和/或左主干病变中,CABG在减少不良心脑血管事件上优于PCI;在12个月中,CABG对三支和/或左主干病变的治疗效果也优于PCI。但还需要更长期的研究。     

Prevalence of unfavorable angiographic characteristics for percutaneous intervention in patients with unprotected left main coronary artery disease.

OBJECTIVES: The goal of this study was to determine the proportion of patients with left main coronary disease (LMCD) with unfavorable characteristics for percutaneous coronary intervention (PCI). BACKGROUND: Published series suggest that LMCD can be treated percutaneously, however, the proportion of patients in whom PCI is an option based on angiographic criteria is unknown. METHODS: In 13,228 consecutive coronary angiograms, 476 (3.6%) patients had < or =60% stenosis of the left main. In 232 patients with unprotected LMCD, the clinical characteristics and angiograms were reviewed with six features chosen as "unfavorable" for PCI: (1) Bifurcation LMCD, (2) occlusion of a major coronary, (3) ejection fraction <30%, (4) occlusion of a dominant RCA, (5) left dominant circulation, and (6) coexisting three-vessel disease. Treatment modality and 1 year mortality were determined. RESULTS: The mean age was 69 years and 68% were male. Unfavorable characteristics were common with at least one unfavorable characteristic seen in 80%. Bifurcation disease was the most common unfavorable characteristic observed (53%) and coexisting three-vessel disease was seen in 38%. Treatment consisted of CABG in 205 (88%), medical therapy in 24 (10%) and PCI in 3 (1%). Among patients referred for CABG, 1 year survival was 88% with similar rates of survival for those with favorable characteristics (86%) compared to those with at least one unfavorable characteristic (88%). CONCLUSIONS: Most patients with LMCD have at least one unfavorable characteristic for PCI suggesting that PCI may be a technically difficult option for most patients with LMCD.

目的探讨冠状动脉左主干病变合并糖尿病患者行经皮冠状动脉介入(percutaneous coronary intervention,PCI)治疗的疗效。方法回顾性分析87例(糖尿病组36例,非糖尿病组51例)冠状动脉左主干病变患者接受PCI治疗的临床资料,比较糖尿病与非糖尿病患者行冠状动脉左主干PCI治疗的方法、疗效和随访结果。结果两组基线资料比较,差异无统计学意义(P0.05)。除外糖尿病组左主干合并前降支病变的比例高于非糖尿病组外,两组病变部位及合并病变冠状动脉分支的比例比较,差异无统计学意义(P0.05)。两组支架植入成功率比较,差异无统计学意义[100%(36/36)vs.98%(50/51),P0.05]。两组介入治疗的各项结果比较,差异无统计学意义(P0.05)。两组PCI治疗后1年各项冠状动脉造影及血管内超声检查结果比较,差异无统计学意义(P0.05),随访期间冠状动脉造影和血管内超声检查均未发现左主干支架内有局部血栓的影象学表现。共83例患者随访到2007年12月,临床随访率95.4%(83/87),随访时间(31.8±6.3)个月。至随访结束,2例死亡,病死率2.4%(2/83),共有7例复发心绞痛,4例经造影证实为左主干支架内再狭窄。结论合并糖尿病的左主干病变患者,在血管内超声指导下进行介入治疗可以获得与非糖尿病患者相同的治疗效果。     

PCI和CABG治疗单纯左主干病变效果进展

随着基础医学、医疗设备、高新技术的进展和循证医学的广泛开展,血运重建技术已经取得了快速的进展。左主干病变可通过内科和外科手段实现心肌血运重建,缓解症状,改善预后和延长寿命。目前血运重建措施有经皮冠状动脉介入治疗(PCI)和冠状动脉旁路移植术(CABG)。但是对于更适当的治疗措施尚无定论。故本文就PCI和CABG在左主干病变患者的治疗效果做一综述。     

Long-term prognostic implication of extracardiac vascular disease in patients undergoing percutaneous coronary intervention

Patients with extracardiac vascular disease were identified from 2,372 consecutive percutaneous coronary intervention (PCI) cases performed between 1997 and 2001. After multivariate adjustment, we found the presence of extracardiac vascular disease to be associated with a significantly higher risk for late mortality (hazard ratio [HR] 1.4, 95% confidence interval [CI] 1.0 to 2.0, p = 0.029). When extracardiac vascular disease was separated into cerebrovascular disease and peripheral vascular disease, cerebrovascular disease was less common but was associated with a trend towards worse survival.     

Hyperuricemia and severity of coronary artery disease in patients undergoing selective percutaneous coronary intervention

Background Hyperuricemia as an independent predictor for presence of coronary artery disease(CAD)has been studied insufficiently. In this study, we evaluated the predictive value of hyperuricemia for the severity of coronary artery disease. Methods A total of 683 patients undergoing elective percutaneous coronary intervention (PCI) were prospectively observed and were divided into two groups (hyperuricemic group, n = 216, and normouricemic group, n = 467). Hyperuricemia (HUA) was defined as an serum uric acid level 7 mg/dL in males and 6 mg/dL in females. Severe CAD was defined as triple-vessel disease or left main disease. Results One hundred and eighteen (55%) severe CAD occurred in the hyperuricemic group and 211(45%) in the normouricemic group (P = 0.02). The median uric acid levels of the severe CAD patients were significantly higher than secondary CAD (single vessel disease or two-vessel disease) patients (379 ± 111 vs 360 ± 105, P = 0.02). Multivariate logistic regression analysis, after adjusting for potential confounding factors, showed that HUA was an independent risk factor of coronary artery disease (odds radio = 1.63, 95% confidence interval, 1.02-2.61, P = 0.040). Moiety of in-hospital complications such as acute heart failure (17.6% vs. 6.2%, P 0.001), hypotension (3.8%, vs. 1.3%, P = 0.04), contrast induced nephropathy (CIN) (7.4% vs. 1.3%, P 0.001) after PCI, were significantly higher in hyperuricemic groups. Conclusions Hyperuricemia was an independent predictor for severe coronary artery disease (triple-vessel disease or left main disease).     

Percutaneous coronary intervention of unprotected left main coronary artery disease

Data have emerged demonstrating the safety and efficacy of percutaneous coronary intervention (PCI) of the unprotected left main (ULM) artery. The 2009 American College of Cardiology/American Heart Association/Society for Cardiovascular Angiography and Interventions focused guidelines for PCI no longer state that ULM PCI is contraindicated in patients with anatomic conditions that are associated with a low risk of procedural complications and clinical conditions that predict an increased risk of adverse surgical outcomes. ULM PCI should be performed by operators with experience in the management of the anatomic complexities of left main and multivessel disease, specifically in issues relating to bifurcation disease, calcification, and hemodynamic support. Patients with ostial or shaft disease have lower risk of restenosis compared with distal bifurcation disease. Drug‐eluting stents (DES) should be used whenever possible as they reduce clinical restenosis. Intravascular ultrasound is an integral component of the procedure as it provides accurate assessment of lesion severity and can confirm optimal stent expansion and apposition. Compliance with dual antiplatelet therapy for at least 12 months is essential if DES are used. A collaborative, multidisciplinary approach with a “Heart Team” represented by a cardiac surgeon, interventional cardiologist, and non‐invasive cardiologist may optimize patient education and objective decision making when obtaining informed consent. Application of clinical and angiographic variables into risk models facilitates appropriate patient selection. Randomized clinical trials will address unanswered issues and help build consensus between cardiology and surgical societies to inform clinical decision making and optimize the outcomes for patients with ULM coronary artery disease. © 2011 Wiley Periodicals, Inc.     

无保护左主干病变合并急性冠状动脉综合征介入与手术治疗对比研究

目的:探讨急性冠状动脉综合征(ACS)合并无保护左主干病变患者经桡动脉介入治疗(TRI)与冠状动脉旁路移植术(CABG)二者的疗效。方法:连续入选2008年3月至2010年12月,于北京安贞医院行经桡动脉介入治疗(n=236)或冠状动脉旁路移植术(n=354)的无保护左主干病变合并ACS患者。对于患者的临床基线特征及冠状动脉病变特征纳入倾向性评分模型进行匹配,得到154对患者。结果:平均随访时间27个月。经过倾向性评分模型进行校正,两组患者的基线资料及病变特征无显著差异。结果显示TRI与CABG两组全因病死率(4.5%vs.6.5%;P=0.454)及心肌梗死发生率(5.2%vs.7.8%;P=0.355)并差异无统计学意义。CABG组患者脑卒中发生率显著增加(零vs.2.6%;P=0.044),而TRI组靶血管重建率(TVR)显著增加(13.0%vs.5.2%;P=0.017)。两组患者复合终点(死亡/心肌梗死/靶血管重建),差异无统计学意义(7.1%vs.12.3%;P=0.124)。结论:对于ACS合并无保护左主干病变患者TRI与CABG的临床复合终点事件风险相似,然而尽管应用药物洗脱支架CABG组患者靶血管重建率仍显著低于介入治疗组。     

Comparison of coronary artery bypass surgery with percutaneous coronary intervention with drug-eluting stents for unprotected left main coronary artery disease.

OBJECTIVES: This study evaluated the clinical outcomes of consecutive, selected patients treated with coronary artery bypass graft (CABG) surgery or percutaneous coronary intervention (PCI) with drug-eluting stents (DES) for unprotected left main coronary artery (ULMCA) disease. BACKGROUND: Although recent data suggest that PCI with DES provides better clinical outcomes compared to bare-metal stenting for ULMCA disease, there is a paucity of data comparing PCI with DES to CABG. METHODS: Since April 2003, when DES first became available at our institution, 123 patients underwent CABG, and 50 patients underwent PCI with DES for ULMCA disease. RESULTS: High-risk patients (Parsonnet score >15) comprised 46% of the CABG group and 64% of the PCI group (p = 0.04). The 30-day major adverse cardiac and cerebrovascular event (MACCE) rate for CABG and PCI was 17% and 2% (p < 0.01), respectively. The mean follow-up was 6.7 +/- 6.2 months in the CABG group and 5.6 +/- 3.9 months in the PCI group (p = 0.26). The estimated MACCE-free survival at six months and one year was 83% and 75% in the CABG group versus 89% and 83% in the PCI group (p = 0.20). By multivariable Cox regression, Parsonnet score, diabetes, and CABG were independent predictors of MACCE. CONCLUSIONS: Despite a higher percentage of high-risk patients, PCI with DES for ULMCA disease was not associated with an increase in immediate or medium-term complications compared with CABG. Our data suggest that a randomized comparison between the two revascularization strategies for ULMCA may be warranted.
