Outcomes of primary percutaneous coronary intervention for acute myocardial infarction with unprotected left main coronary artery occlusion

Background : We determined the in‐hospital and the long‐term outcomes of primary percutaneous coronary intervention (PCI) for acute left main coronary artery (LMCA) occlusion. Methods : Between 1988 and 2009, 72 patients with acute myocardial infarction (AMI) underwent primary PCI for unprotected LMCA occlusion. The short‐ and the long‐term outcomes of primary PCI in these patients were retrospectively evaluated. Results : Upon arrival, cardiogenic shock was observed in 33 (46%) patients and cardiopulmonary arrest (CPA) in 12 (17%). Twenty‐three (32%) required extracorporeal life support and 64 (89%) intra‐aortic balloon pumping. Although successful reperfusion was achieved in 60 (83%) patients, in‐hospital death was observed in 32 (44%). Multivariate analysis revealed predictors of in‐hospital death to be CPA on arrival (RR, 7.05; 95% CI: 1.28–39.0; P = 0.025). During 1.7 ± 2.9 years of follow‐up, 10 of the 40 hospital survivors died. All presenting CPA on arrival died within 2 years. Although the estimated survival of the all study patients was only 26.2% at 8 years by the Kaplan–Meier methods, those without shock/CPA on arrival showed nearly flat survival curve after 4 years. Conclusions : Despite performance of primary PCI, patients with AMI due to LMCA occlusion were associated with >50% in‐hospital mortality. Hemodynamic deficit upon arrival was the major determinant of their poor hospital outcomes. The hospital survivors, however, were associated with favorable long‐term outcomes. © 2012 Wiley Periodicals, Inc.

左主干急性闭塞或狭窄所致急性心肌梗死的急诊介入治疗

目的总结左主干急性闭塞或狭窄所致急性心肌梗死(AMI)患者急诊经皮冠状动脉介入治疗(PCI)的经验,探讨急诊PCI在此类患者中的安全性和有效性。方法从1995年1月至2004年12月,在1343例急诊PCI中,共有11例梗死相关血管为左主干。11例患者均为男性,年龄43~70岁,平均(56·4±9·2)岁,其中6例(54·5%)入院时即存在严重心原性休克。所有患者均在主动脉内球囊反搏支持下接受急诊PCI治疗。结果8例急诊置入支架,余3例仅行球囊扩张,后者有2例术后接受急诊冠状动脉旁路移植术。住院期间死亡5例(45·5%),存活的6例患者均完成3个月随访,其中4例随访超过2年,1例于术后4年猝死,1例患者术后5年重复造影检查结果良好。对比分析提示术前存在良好的侧支循环可能是影响此类患者急诊PCI术后疗效的因素。结论左主干急性闭塞或严重狭窄所致的AMI患者病情凶险,急性期死亡率高。侧支循环形成与否,治疗策略和预后不同,主动脉内球囊反搏支持下急诊PCI治疗可以挽救部分患者的生命和改善预后,对于侧支循环不良的患者,部分再灌注策略可能为一种有效手段之一,值得进一步研究。     

Percutaneous coronary intervention for acute myocardial infarction due to unprotected left main coronary artery occlusion

Acute myocardial infarction (AMI) due to unprotected left main coronary artery (ULMCA) occlusion is an uncommon clinical entity, but often leads to severe clinical deterioration, with devastating sequalae including fatal arrhythmias, abrupt and severe circulatory failure, and sudden cardiac death. Recent guidelines have promoted treatment with percutaneous coronary intervention (PCI) as a class IIa recommendation alongside coronary artery bypass grafting (CABG), but the data are still unclear regarding optimal revascularization strategy for patients with ST‐segment elevation myocardial infarction (STEMI) and non‐STEMI (NSTEMI) with ULMCA culprit. PCI has the advantages of offering rapid reperfusion to critically ill patients, often those with prohibitive risk for surgical revascularization, with acceptable short‐ and long‐term outcomes. Recent studies demonstrate that PCI of the ULMCA is a viable alternative to CABG for appropriate patient populations, including those with ULMCA occlusion and those in cardiogenic shock, Thrombolysis In Myocardial Infarction (TIMI) flow grade 3, and significant comorbidities. A randomized trial comparing PCI with CABG is needed to clarify the ideal revascularization strategy, though the clinical picture of these critically ill patients may preclude such studies. © 2014 Wiley Periodicals, Inc.     

Survival after myocardial infarction caused by acute left main coronary artery occlusion: case report and review of the literature

We report a 44-year-old white male presenting with an acute anterior myocardial infarction. Cardiac catheterization at 2 weeks postinfarction revealed total occlusion of the left main coronary artery. There was a normal dominant right coronary artery supplying moderate collaterals to the left coronary system. The patient was managed with conservative therapy and was N.Y.H.A. functional class II on followup 2 years later. A review of the literature relative to myocardial infarction caused by acute left main coronary artery occlusion is presented, and unique features of these cases are described.     

左主干急性闭塞的急诊PCI分析

目的探讨左主干病变导致的急性心肌梗死与心源性休克的关系以及急诊经皮冠状动脉介入对其的疗效。方法1999年9月至2005年6月连续就诊于中国医科大学附属盛京医院心内科并且行急诊冠脉造影的急性心肌梗死患者752例,发现因左主干急性闭塞导致血管床灌注评分(TIMI)血流在2级或2级以下者16例(2.12%),所有患者行急诊经皮冠状动脉介入(PCI)治疗,观察住院期间病死率。结果16例患者中,9例(56.25%)住院期间死亡,7例(43.75%)出院。死亡组再灌注成功率42.86%,生存组为100%,两组间比较差异有显著性意义(P=0.029)。未成功再灌注的5例均由无复流引起,其中3例可见肉眼血栓,5例患者均死亡。16例患者中有12例发生心源性休克,发生率为75.00%,死亡组发生率100%,生存组42.85%,两组间比较差异有显著性意义(P=0.019)。心源性休克患者住院病死率为75.00%高于无休克者,死亡风险是无休克者的4倍[比值比(OR)=4.0,95%可信区间1.50～10.66,P=0.019]。结论左主干闭塞导致的急性心肌梗死患者出现心源性休克的发生率较高,且即使成功地施行了PCI治疗,也有较高的病死率。不过,急诊PCI在临床实践仍然是有效可行的治疗手段,可以有效地挽救部分生命。
