Background: Drug-eluting stents (DES) constitute a major breakthrough in restenosis prevention after percutaneous coronary intervention (PCI). This study compared the clinical outcomes of PCI using DES versus coronary artery bypass graft (CABG) in patients with multivessel coronary artery disease (MVD) in real-world. Methods: From January 2003 to December 2004, 466 consecutive patients with MVD underwent revascularization, 235 by PCI with DES and 231 by CABG. The study end-point was the incidence of major adverse cardiovascular events (MACEs) at the first 30 days after procedure and during follow-up. Results: Most preoperative characteristics were similar in the two groups, but left main disease (24.7% vs 2.6%, P<0.001) and three-vessel disease (65% vs 54%, P = 0.02) were more prevalent in CABG group. The number of coronary lesions was also greater in CABG group (3.7 ± 1.1 vs 3.3 ± 1.1, P<0.001). Despite higher early morbidity (3.9% vs 0.8%, P = 0.03) associated with CABG, there were no significant differences in composite MACEs at the first 30 days between the two groups. During follow-up (mean 25±8 months), the incidence of death, myocardial infarction, or cerebrovascular event was similar in both groups (PCI 6.3% vs CABG 5.6%, P = 0.84). However, bypass surgery still afforded a lower need for repeat revascularization (2.8% vs 10.4%, p = 0.001). Consequently, overall MACE rate (14.5% vs 7.9%, P = 0.03) remained higher after PCI. Conclusion: PCI with DES is a safe and feasible alternative to CABG for selected patients with MVD. The reintervention gap was further narrowed in the era of DES. Aside from restenosis, progression of disease needs to receive substantial emphasis. [source]


Marked Improvements in Outcomes of Contemporary Percutaneous Coronary Intervention in Patients with Diabetes Mellitus

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 6 2006
ANDREW M. FREEMAN M.D.
We sought to determine if advances in percutaneous coronary intervention (PCI) are associated with better outcomes among patients with diabetes mellitus (DM). Patients with DM enrolled in the National Heart, Lung, and Blood Institute (NHLBI) early PTCA Registry (1985,1986) were compared to those in the subsequent contemporary Dynamic Registry (1999,2002) for in-hospital and one-year cardiovascular outcomes. The study population included 945 adults with DM, 325 from the PTCA Registry and 620 from the Dynamic Registry. Multivariable Cox regression models were built to estimate the risk of clinical events. Dynamic Registry patients were older, had more noncardiac comorbidities, and a lower mean ejection fraction (50.5% vs 57.8%, P , 0.001) compared to the PTCA Registry patients. The incidence of in-hospital mortality (1.9% vs 4.3%, P , 0.05), myocardial infarction (MI) (1.0% vs 7.4%, P , 0.001), and coronary artery bypass grafting (CABG) (0.8% vs 6.2%, P , 0.001) were all significantly lower and independent of the use of stents. One-year adverse events including MI (4.9% vs 11.0%, P , 0.001), CABG (6.4% vs 15.0%, P , 0.001), and need for repeat revascularization (18.7% vs 33.3%, P , 0.001) were all lower in the Dynamic Registry. The relative risk of death at 1 year was significantly less for patients in the Dynamic Registry (RR 0.56, 0.34; 0.92, P = 0.02). Although Dynamic Registry patients with diabetes had more advanced coronary disease, in-hospital and late adverse events were lower. A combination of the use of stents and an increase in adjunctive medical therapy are likely responsible for the observed improvements in outcomes in contemporary PCI. [source]


Mortality Benefit of Beta Blockade in Patients with Acute Coronary Syndromes Undergoing Coronary Intervention:

Capture, Epilog, Epistent, Pooled Results from the Epic, Rapport Trials
The effects of beta blocker therapy in the settings of heart failure and coronary artery disease have been well described, although little data exist in patients presenting with acute coronary syndromes undergoing percutaneous coronary intervention. The current study will attempt to evaluate the efficacy of beta blocker therapy in this setting. Pooled data from five randomized, controlled trials of abciximab during coronary intervention were used to analyze the clinical efficacy of beta blocker therapy. The pooled analysis evaluated the end points of all-cause mortality, myocardial infarction, repeat revascularization, and the combined endpoint of death and myocardial infarction in 2,894 patients. At 30 days, death occurred in 12 of 1,939 (0.6%) patients receiving beta blocker therapy and in 19 of 955 (2.0%) patients not receiving beta blocker therapy, (P < 0.001). At 6 months, death occurred in 33 of 1,939 (1.7%) patients receiving beta blocker therapy and 35 of 955 (3.7%) not receiving beta blocker therapy, (P < 0.001). After creating a propensity model and adjusting for variables predictive of mortality in the multivariable analysis, beta blocker therapy continued to be associated with a significant reduction in mortality. The findings were similar to those shown for the effects of beta blocker therapy in separate subgroups of patients with unstable angina and acute myocardial infarction. This analysis demonstrates a lower short-term mortality in patients receiving beta blocker therapy who undergo percutaneous coronary intervention for unstable angina or acute myocardial infarction.

Treatment of Palmaz-Schatz In-stent Restenosis: 6,Month Clinical Follow-up

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 5 2000
HUAY-CHEEM TAN M.D.
To identify predictors of Palmaz-Schatz in-stent restenosis and determine outcomes of treatment, we assessed 6,month outcomes in 402 patients who had coronary intervention with stent placement; 60 (15%) developed angiographic and clinical evidence of restenosis. Predictors of restenosis included family history of cardiovascular disease, prior bypass surgery, nonelective stenting, stenting of a vein graft, and multiple stents. Of 60 patients with stent restenosis, 47 had repeat percutaneous intervention and 10 had bypass surgery; only 1 of these 10 patients developed symptoms requiring repeat revascularization. Of the 47 with repeat percutaneous intervention, 32 (68%) had conventional balloon angioplasty; the others had perfusion balloon catheters, laser ablation, and repeat coronary stenting. During follow-up, 22 (47%) of these 47 patients suffered recurrent angina, myocardial infarction, or death. A third revascularization procedure was performed in 14 (30%), including 5 referred for bypass. This study shows the limitations of percutaneous modalities for patients with Palmaz-Schatz in-stem restenosis. Such patients are likely to have recurrent symptoms and to undergo repeat target-vessel revascularization. [source]


Five-year clinical outcomes after coronary stenting of chronic total occlusion using sirolimus-eluting stents: Insights from the rapamycin-eluting stent evaluated at Rotterdam Cardiology Hospital,(Research) Registry,

Abstract Background: The use of drug eluting stents (DES) in patients with a successfully recanalized chronic total occlusion (CTO) has been associated with a significant decrease in the need for repeat revascularization, and a favorable short-term clinical outcome when compared with the use of bare metal stents (BMS). Our group, however, has previously reported similar rates of target lesion revascularisation (TLR) and major adverse cardiovascular events (MACE) at 3 years follow-up in patients with a successfully opened CTO who were treated with either a sirolimus eluting stent (SES) or a BMS. The objective of this report was to evaluate the outcomes of these patients at 5-years clinical follow-up. Methods and Results: A total of 140 (BMS 64, SES 76) patients with successfully opened CTOs were included. Seven patients died in the BMS group whilst nine patients died in the SES group (P = 0.90). Noncardiac death was the major component of all-cause mortality (11 noncardiac deaths vs. 5 cardiac). There were two and three myocardial infarctions (MI) in the BMS and SES group, respectively (P = 1.0). The composite of death and MI occurred in seven (10.9%) and eleven (14.5%) patients in the BMS and SES group, respectively (P = 0.53). Clinically driven TLR was performed in eight patients (12.5%) in the BMS group, and five (6.6%) in the SES group (P = 0.26). Non-TLR target vessel revascularization was performed in one patient in the BMS group, and four in the SES group (P = 0.37). The 5-year device-oriented cumulative MACE rate was 15.6% and 11.8% in the BMS and SES group, respectively (P = 0.56). Conclusion: In patients with a successfully treated CTO, clinical outcome after 5 years was similar between SES and BMS, however, clinically driven TLR was slightly higher in the BMS group. © 2009 Wiley-Liss, Inc.

Impact of sirolimus-eluting stents on outcomes of patients treated for acute myocardial infarction by primary angioplasty

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 4 2005
Edouard Cheneau MD
Abstract Sirolimus-eluting stents (SESs) are currently being used in patients undergoing percutaneous coronary intervention (PCI). SESs have not been evaluated in the treatment of acute myocardial infarction by primary angioplasty. We report our initial experience with SESs implanted during primary angioplasty. One hundred and three patients were treated within 12 hr after onset of acute myocardial infarction (AMI) with primary angioplasty and SES implantation. Those patients were compared to 504 patients treated with bare metal stents (BMSs). Angiographic success (TIMI flow grade 3 and residual stenosis < 50%) was completed in 98% of patients with SESs and no subacute stent thrombosis was reported. In-hospital outcomes were similar in the SES and BMS groups. At 6 months, major cardiac events were less frequent in the SES group than in the BMS group (9% vs. 24%, respectively; P < 0.001), driven by a lesser need for repeat revascularization with SESs (1% vs. 10.3% with BMSs; P = 0.014). Mortality at 6 months was 7% with SESs and 11% with BMSs (P = 0.14). SESs are safe and effective for the treatment of AMI by primary angioplasty. As compared to BMSs, SESs improve long-term outcome after AMI, mainly by reducing the need for repeat revascularization. © 2005 Wiley-Liss, Inc. [source]


Percutaneous coronary intervention or bypass surgery in multivessel disease?

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 2 2004
A tailored approach based on coronary pressure measurement
Abstract The optimal revascularization strategy, percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG), for patients with multivessel coronary artery disease (MVD) remains controversial. The aim of the present study was to compare the long-term outcomes after selective PCI of only hemodynamically significant lesions (fractional flow reserve, or FFR < 0.75) to CABG of all stenoses in patients with MVD. In 150 patients with MVD referred for CABG, FFR was determined in 381 coronary arteries considered for bypass grafting. If the FFR was less than 0.75 in three vessels or in two vessels including the proximal left anterior descending (LAD) artery, CABG was performed (CABG group). If only one or two vessels were physiologically significant (not including the proximal LAD), PCI of those lesions was performed (PCI group). Of the 150 patients, 87 fulfilled the criteria for CABG and 63 for PCI. There were no significant differences in the angiographic or other baseline characteristics between the two groups. At 2-year follow-up, no differences were seen in adverse events, including repeat revascularization (event-free survival 74% in the CABG group and 72% in the PCI group). A similar number of patients were free from angina (84% in the CABG group and 82% in the PCI group). Importantly, the results in both groups were as good as the surgical groups in previous studies comparing PCI and CABG in MVD. In patients with multivessel disease, PCI in those with one or two hemodynamically significant lesions as identified by an FFR < 0.75 yields a similar favorable outcome as CABG in those with three or more culprit lesions despite a similar angiographic extent of disease.

Chourmouzios A. Arampatzis MD
Abstract The aim of this study was to evaluate the effectiveness of sirolimus-eluting stent (SES) implantation for patients with multivessel disease, which included left anterior descending artery (LAD) treatment. Since April 2002, SES has been utilized as the device of choice for all interventions in our institution as part of the Rapamycin-Eluting Stent Evaluated at Rotterdam Hospital (RESEARCH) registry. In the first 6 months of enrolment, 99 consecutive patients (17.6% of the total population) were treated for multivessel disease involving the LAD. The impact of SES implantation on major adverse cardiac events (MACE) was evaluated. All the patients received SES in the LAD. Additional stent implantation in the right coronary artery, the left circumflex, or in all three major vessels was attempted successfully in 32 (32%), 51 (52%), and 16 (16%) of the treated patients respectively. During a mean follow-up of 360 ± 59 days (range, 297,472 days), we had one death, one non-Q-wave myocardial infarction, and eight patients required subsequent intervention. The event-free survival of MACE at 1 year was 85.6%. SES implantation for multivessel disease in a consecutive series of patients is associated with low incidence of adverse events. The reported results are related predominantly to the reduction in repeat revascularization. Catheter Cardiovasc Interv 2004;63:57,60. © 2004 Wiley-Liss, Inc. [source]


Effect of stents in reducing restenosis in small coronary arteries: A meta-analysis

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 4 2004
FSCAI, Paul T. Vaitkus MD
Abstract The ability of stents to reduce restenosis was established in larger coronary arteries. Clinical trials of stenting in smaller vessels have yielded conflicting results due in part to their sample sizes. The aim of this meta-analysis was to increase the statistical power by pooling data from these clinical trials. Trials were identified from Medline search, review of recent cardiology meetings' abstracts, and manual review of bibliographies. Studies were included if they were prospective randomized controlled trials. Endpoints examined included a dichotomized definition of angiographic restenosis, target lesion revascularization (TLR), target vessel revascularization (TVR), or any repeat revascularization. Pooling of data was performed by calculating a Mantel-Haenszel odds ratio (OR). The analysis included 2,598 patients enrolled in eight clinical trials. Stenting significantly reduced restenosis (OR = 0.62; 95% CI = 0.61,0.63). Concordantly, stenting reduced TLR (OR = 0.49), TVR (OR = 0.90), and any revascularization (OR = 0.48). This meta-analysis supports the hypothesis that stenting reduces restenosis in small coronary arteries as well as in larger coronary arteries. The apparent discordant result of individual clinical trials was due in part to underpowering related to small sample sizes. Catheter Cardiovasc Interv 2004;62:425,429. © 2004 Wiley-Liss, Inc.
