目的对比冠状动脉杂交术与经皮冠状动脉介入治疗(PCI)治疗冠状动脉多支病变患者中远期临床疗效及安全性。方法采用前瞻性随机对照研究,从2012年1月到2014年6月,选择行冠状动脉造影诊断为冠状动脉多支病变,适宜行冠状动脉旁路移植术(CABG)及PCI处理的冠心病患者102例,随机分为两组:冠状动脉杂交术组(n=53)和PCI组(n=49),治疗目标为达到最大限度完全血运重建。术后1、3、6、9、12个月及两年随访,术后12个月行冠状动脉造影检查,评估靶血管通畅率及SYNTAX评分,记录患者临床状况及心血管不良事件,评价两组患者两年内心血管不良事件的发生率、生存率。结果冠状动脉杂交术组造影剂用量低于PCI组(P0.001),两组IABP支持、监护室时间、LCX及RCA置入支架数差异无统计学意义(P0.05),冠状动脉杂交术组平均住院时间、总支架长度及术后hs-CRP峰值低于PCI组,冠状动脉杂交术组造影剂肾病、急性心衰、复发心绞痛及术后低血压发生率也低于PCI组(P0.05),两组院内再次心肌梗死、靶血管血运重建、脑血管意外及死亡差异无显著性(P0.05)。术后随访2.4年,平均16.2±11.3个月。随访期间冠状动脉杂交术组再次心肌梗死、靶血管血运重建、急性心衰及复发心绞痛发生率低于PCI组(分别是1.9%比8.2%、1.9%比8.2%、3.8%比12.2%、5.7%比14.3%,P0.05),两组脑血管意外、主要出血事件及死亡差异无显著性;冠状动脉杂交术组两年总死亡率为3.8%,PCI组为4.1%。冠状动脉杂交术组术后1年靶血管通畅率为94.1%,高于PCI组的85.1%,SYNTAX评分低于PCI组(P0.05)。结论与PCI术相比,冠状动脉杂交术可以减少冠状动脉多支病变患者治疗后中远期不良事件,且手术安全性高。     

不完全血运重建策略对老年冠状动脉多支血管病变患者预后的影响

目的回顾性分析经皮冠状动脉介入的完全及部分血运重建术对老龄冠状动脉多支血管病变患者预后影响、疗效。方法 153例年龄≥70岁的老年患者,2005年10月至2008年3月入院行冠状动脉造影检查发现为多支病变行经皮冠状动脉介入(PCI)治疗。分为接受经皮冠状动脉介入治疗的完全血运重建(85例)组和接受介入治疗的部分血运重建患者(68例)。记录分析两组患者临床资料、PCI结果以及围术期并发症和随访期间主要不良心脏事件(MACE)、死亡率发生情况。进行Cox回归分析影响此类患者预后的相关因素。结果老年冠心病多支病变患者PCI进行血运重建完全者与血运重建不完全者的院内围手术期及随访1年后的死亡、急性心肌梗死、总心脏死亡率等MACE的发生率差异无统计学意义。Cox多因素回归分析表明患者PCI术后1年MACE发生率与是否完全血运重建无关(HR1.328,95%CI0.253～2.652,P>0.05)。结论介入治疗完全血运重建与不完全血运重建策略对老年冠状动脉多支病变的1年临床效果相似。

Acute and intermediate‐term procedural results using cypher stenting to treat multi‐vessel coronary artery disease

OBJECTIVE: We examined our experience using the sirolimus eluting stents (Cypher) as an alternative to surgical revascularization in carefully selected cohort of patients undergoing multi‐vessel percutaneous coronary intervention. METHODS: Fifty consecutive patients with multi‐vessel disease who were good candidates for both surgical and percutaneous revascularization were included in the current analysis. All patients underwent a careful clinical evaluation prior to the intervention, and they were followed for procedural and clinical outcomes for nine months. RESULTS: Mean age was 64±11 years (40 males, 30% diabetics) and 10 patients (20%) had three‐vessel disease. Angina class was 2.7±0.6 at baseline. Overall, 116 lesions were treated using 122 stents (mean 2.4 stents per patient). Total mean stent length was 43±12?mm (range: 21–90?mm). Overall, one patient died during follow‐up (2%), no patient had stroke or Q wave MI and one patient experienced non‐Q myocardial infarction. There was no documented stent thrombosis and two patients (4%) underwent target‐vessel revascularization. The hierarchical cumulative major adverse cardiac event rate was 8% and the cardiac event‐free survival rate was thus 92%. CONCLUSION: Multi‐vessel stenting using Cypher stents is a viable treatment strategy in selected group of patients with multi‐vessel coronary artery disease. It is associated with excellent intermediate‐term clinical outcomes and thus it could serve as the primary revascularization strategy of choice in appropriate candidates.     

The influence of diabetes mellitus on the practice and outcomes of percutaneous coronary intervention in the community: a report from the HCA database

BACKGROUND: Diabetics remain a high-risk group for those undergoing percutaneous coronary intervention (PCI) using balloon angioplasty and/or intracoronary stents for myocardial revascularization. The objective of this study is to compare clinical characteristics, demographics, procedure indications, lesion characteristics, and acute and long-term outcomes between diabetic patients and non-diabetic patients in a community based PCI registry. METHODS AND RESULTS: Information on patient demographics, coronary risk factors, lesion characteristics, procedures, and outcomes were derived from an HCA, Inc. database on all patients undergoing a PCI procedure in one of four community cardiac catheterization laboratories (CCL). A total of 3,139 patients who underwent PCI procedures from July 1, 1999 through September 30, 2000 were enrolled in this study. Approximately one-third of these patients completed a follow-up survey one year after their initial encounter. Analysis was limited to those patients undergoing PCI of native vessels with stents or conventional balloon angioplasty; patients with target lesions in bypass grafts or those treated with atherectomy were excluded. Approximately 23.5% of the patients enrolled in the study were diabetic. This study found no significant difference in any acute outcome between diabetic and non-diabetic patients in the hospital episode associated with the index PCI procedure. However, data from the 1-year follow-up survey indicates diabetic patients tended to have more target lesion revascularization (TLR) (13.6% versus 8.9%; p = 0.07) and more target vessel revascularization (TVR) (17.6% versus 12.7%; p = 0.058) than non-diabetic patients. In addition, adjusted odds ratios indicate that diabetic patients were 1.6 times more likely to have a second PCI procedure in another vessel (p = 0.013), 2.4 times more likely to undergo bypass surgery (p = 0.003), 1.9 times more likely to undergo an additional revascularization procedure (p < 0.001) and 1.8 times more likely to experience any major adverse cardiac events (p < 0.001) than non-diabetic patients during the follow-up period. CONCLUSIONS: This study indicates that selected diabetic patients can be treated for myocardial revascularization using PCI procedures with acceptable acute outcomes. However, diabetic patients undergoing PCIs have significantly more disease progression and are more likely to experience the need for recurrent revascularization.     

Patient outcomes after fibrinolytic therapy for acute myocardial infarction at hospitals with and without coronary revascularization capability

OBJECTIVES: This study evaluated clinical outcomes in patients with acute myocardial infarction (MI) treated with fibrinolytic therapy in hospitals with and without coronary revascularization capability. BACKGROUND: Patients with MI may have better outcomes when admitted to certain hospitals with coronary revascularization capability. Development of regional heart care centers for the treatment of MI has been proposed. METHOD: We performed a retrospective analysis of 25,515 U.S. patients enrolled in the Global Use of Streptokinase and TPA (alteplase) for Occluded Coronary arteries (GUSTO)-I trial. Outcomes of patients admitted to hospitals with and without coronary revascularization capability were analyzed. We also analyzed patients who remained in hospitals without coronary revascularization capability compared with those transferred to hospitals with revascularization capability. RESULTS: Baseline characteristics and complications were similar between patients in the two hospital types. Patients in hospitals with coronary revascularization capability more often underwent cardiac catheterization (78.1% vs. 59.2%; p < 0.001), angioplasty (34.6% vs. 22.6%; p < 0.001), or bypass surgery (14.1% vs. 10.4%; p < 0.001) but had a similar adjusted 30-day (odds ratio [OR] 0.91, 95% confidence interval [CI] 82 to 1.02) and one-year (OR 0.98, 95% CI 0.90 to 1.07) mortality. Forty percent of patients admitted to hospitals without revascularization capability were transferred, with 94% of transfer patients undergoing angiography. Almost 80% of transfers occurred >48 h after hospital admission. CONCLUSION: Patients receiving fibrinolytic therapy for acute MI admitted to hospitals without coronary revascularization capability appear to have outcomes similar to those of patients admitted to hospitals with such capability when aspirin and beta-adrenergic blocking agents are given appropriately and transfer is available for angiography and angioplasty as needed.     

Five-year clinical follow up after intracoronary radiation for the prevention of in-stent restenosis

Intracoronary radiation therapy (IRT), utilizing both gamma- and beta-emitting radiation sources, is considered to be a safe and effective treatment for in-stent restenosis (ISR). Although no longer in clinical use, a significant number of patients were treated in the past with IRT, and their long-term outcomes have not been well documented. The aim of the present analysis was to document the long-term outcomes of all patients who underwent IRT at our institution for the prevention of recurrence of ISR. Data were collected from 132 patients (148 irradiated lesions) treated with IRT at our institution between March 1999 and January 2004. Clinical and angiographic data were collected over a 5-year period. Patients were divided into 2 groups: those with failed IRT (n = 65), defined as a procedure that resulted in a major adverse cardiac event: death, myocardial infarction, target lesion revascularization, target vessel revascularization or coronary artery bypass graft surgery at any time during the follow-up period, and patients with successful IRT (n = 67). Both groups were identical regarding baseline clinical and angiographic characteristics, with the exception of a higher percentage of multivessel disease and diffuse restenosis in patients who failed IRT (p = 0.01). At 1-year follow up, slightly less than half (43%) of those patients in the failure group experienced a major adverse cardiac event. During the long-term follow up period, half of all patients who underwent IRT at our institution experienced a major adverse cardiac event, 61 patients (46%) either died or underwent a revascularization procedure, 16 patients (24%) had a myocardial infarction or died, and 55 patients (42%) required repeat coronary revascularization. The average time to develop a major adverse cardiac event was 14.6 +/- 15 months. Therefore, during long-term follow up following IRT for the prevention of ISR, half of all patients developed a major cardiovascular event, mainly due to the need for repeat revascularization procedures.     

Practice and outcomes of percutaneous coronary intervention in the community before drug-eluting stents: a report from the HCA database

BACKGROUND: Percutaneous coronary intervention (PCI) using balloon angioplasty and/or intracoronary stents has increasingly become the treatment choice for myocardial revascularization. While acute clinical outcomes of the community-based PCI procedures have been examined, much less is known about long-term revascularization rates, disease progression and other adverse outcomes. METHODS AND RESULTS: Information on patient demographics, coronary risk factors, lesion characteristics, procedures and outcomes were derived from an HCA, Inc. database on all patients undergoing a PCI procedure in one of four community cardiac catheterization laboratories. A total of 3,192 consecutive patients were enrolled from July 1, 1999 through September 30, 2000. Analysis was limited to those patients undergoing PCI of native vessels with stents or conventional balloon angioplasty; target lesions in bypass grafts or those treated with atherectomy were excluded. Approximately one-third of enrolled patients were surveyed concerning their utilization of cardiovascular services 1 year following their initial procedure. The 1-year target lesion revascularization (TLR) was 9.9% while target vessel revascularization was 13.5%. Overall, 27.6% of patients underwent repeat revascularization within 1 year; 24.7% underwent at least 1 additional PCI and 5.6% underwent coronary artery bypass graft surgery. A total of 4.5% of patients reported an interval acute myocardial infarction with a major adverse cardiac event rate of 30.3% at 1 year. CONCLUSION: While clinically significant restenosis remains a problem for 10 15% of patients undergoing PCI, progression of coronary artery disease elsewhere appears to be an equally powerful driver in the need for recurrent revascularization. This analysis of contemporary PCI practice prior to drug-eluting stent utilization suggests that while these novel devices will likely reduce the incidence of TLR, many patients with coronary artery disease will still require additional revascularization for disease progression.     

Factors Influencing Clinical Outcomes After Revascularization in the Asymptomatic Cardiac Ischemia Pilot (ACIP)

Abstract Background and Aim The Asymptomatic Cardiac Ischemia Pilot is the first randomized trial where revascularization involved choice of either coronary bypass or angioplasty used in an early or a delayed symptom-driven approach. One-year outcomes were favorable (reduced recurrent ischemia and adverse outcomes) for an early revascularization strategy (within 4 weeks), compared with an early medical strategy when revascularization was delayed until symptom-driven. This ancillary study examined variables influencing outcomes after these 2 revascularization approaches (early vs. delayed until symptom-driven). Methods: Participants were clinically stable coronary disease patients with stress-induced and daily life ischemia who underwent revascvularization. Characteristics associated with clinical outcomes occurring within the year following revascularization were examined using Cox regression analysis. Results: A total of 262 patients received revascularization; 170 in the early approach and 92 in the delayed symptom-driven approach. Thirty-three patients had adverse outcomes (death, nonfatal myocardial infarction, or repeat revascularization) during l-year follow-up. The most important independent predictor of improved outcome during the follow-up year was attempted revascularization of ≥ 66% of vessels with significant stenosis for the early (risk ratio [RR] 0.25, 95% confidence interval [CI] 0.09–0.67) and the delayed (RR 0.21, CI 0.08–0.58) approaches. Factors such as age, stress test results, and coronary angiographic findings did not predict clinical outcome. Conclusions: Our findings are important in the planning of a large trial with longer follow-up.

目的评价药物洗脱支架治疗冠心病合并2型糖尿病的疗效。方法药物洗脱支架组为2002年12月～2004年11月,冠心病合并2型糖尿病患者68例,因冠状动脉内原发病变接受药物洗脱支架置入;对照组为我科经皮冠状动脉介入术资料库中抽取自2001年3月以来冠心病合并2型糖尿病56例,因原发病变置入普通支架。结果术后1年内随访结果,药物洗脱支架组与普通支架组手术成功率相似(分别为97.1%与98.2%,P=1.00);累计1年内发生主要不良心脏事件率分别为19.1%与35.7%(P=0.037,比数比为0.425,95%置信限为0.188～0.961),再次血运重建分别为10.3%与25.0%(P=0.03,比数比0.344,95%置信限0.128～0.925),发生死亡、急性心肌梗死两组无差异。结论冠心病合并2型糖尿病患者常规置入药物洗脱支架安全有效,与普通支架相比,能显著降低1年主要不良心脏事件发生率。     

Effects of statins on restenosis after coronary stent implantation

Experimental data and preliminary clinical studies suggest that lipid-lowering drugs might have a beneficial effect on restenosis after coronary angioplasty. Recently, statins have been focused on prevention of restenosis after coronary stent implantation. However, their benefit has not yet been established. The authors studied the effects of statins on stent restenosis. We compared retrospectively the quantitative coronary angiographic (QCA) variables between 62 dyslipidemic patients treated with statins (pravastatin or fluvastatin) and 62 normolipidemic patients, as a control, treated without statins after undergoing successful coronary stent implantation with 6-month follow-up angiography from May 1999 to December 2002. Major cardiac events were about the same in both groups. Each of the QCA variables before and immediately after coronary stenting was similar in the 2 groups. At follow-up angiography, however, minimal lumen diameter (MLD) (2.12 -/+ 0.73 vs 1.78 -/+ 0.7; p < 0.01) was larger in the statin group than in the normolipidemia group. Both restenosis rate (15% vs 31%; p = 0.05) and target lesion revascularization rate (10% vs 24%; p = 0.05) were lower in the statin group than in the normolipidemia group. Statin reduced restenosis rate. The efficacy of statins appears to be dependent on their pleiotropic effects on vascular wall rather than on lipid-lowering effects.

目的探讨2型糖尿病合并急性冠状动脉综合征(acute coronary syndrome,ACS)患者经血运重建治疗对远期预后的影响。方法选择ACS患者424例,根据是否合并糖尿病分为糖尿病组(120例)和无糖尿病组(304例)。分析两组患者冠状动脉造影、冠状动脉支架置入术的临床资料以及两组患者术后2年的随访资料。结果糖尿病组患者冠状动脉3支、多支、闭塞性病变比率明显高于无糖尿病组(P<0.05):糖尿病组患者不完全血运重建的比率高于无糖尿病组,完全血运重建的比率低于无糖尿病组(P<0.05):糖尿病组惠青生活质量改善率低于无糖尿病组,重大心血管事件的发生率高于无糖尿病组(P<0.05)。结论糖尿病合并ACS患者冠状动脉以3支、多支、重度、闭塞病变为主的特点,且其远期预后较差。     

The efficacy of sirolimus-eluting stents versus bare metal stents for diabetic patients undergoing elective percutaneous coronary intervention

BACKGROUND: Diabetes mellitus is a well-known risk factor for future adverse cardiac events after coronary intervention with conventional metal stents. In this study, the impact of sirolimus-eluting stents (SES) were evaluated in a consecutive group of diabetic patients undergoing elective percutaneous coronary treatment and compared to a population treated with bare metal stents. METHODS AND RESULTS: From April 2002, a policy of routine SES implantation has been instituted in our hospital. During 1 year of enrollment, a total of 112 consecutive diabetic patients with de novo coronary lesions were electively treated with SES (SES group). A similar group for comparison comprised 118 consecutive patients treated with bare metal stents in the preceding period (the pre-SES group). After 1-year follow-up, the cumulative rate of major adverse cardiac events (death, myocardial infarction, and any repeat revascularization) was 17.3% in the SES group versus 30.2% in the pre-SES group (hazard ratio, 0.54 [95% confidence interval, 0.32-0.91]; p = 0.02), mainly due to a marked reduction in the need for repeat revascularization (10.2% versus 23.5%; hazard ratio, 0.40 [95% confidence interval, 0.21-0.78]; p = 0.007). CONCLUSIONS: Routine utilization of SES for diabetic patients significantly reduces the rate of adverse cardiac events at 1 year compared to bare metal stents.
