The benefit of abciximab in percutaneous coronary revascularization is not device-specific.

Abciximab has been shown to decrease adverse outcomes after percutaneous coronary interventions, but it is unclear whether this beneficial effect is more or less pronounced with specific devices. This study sought to determine the relative magnitude of the benefit of abciximab among different interventional devices. Data from the 5 placebo-controlled trials of abciximab during coronary intervention were pooled. Patients were divided into groups based on whether they received balloon angioplasty alone, elective stenting, bailout stenting, or directional coronary atherectomy. In the patients undergoing balloon angioplasty, the 30-day hazard ratio for death or myocardial infarction (MI) in the group randomized to abciximab versus the placebo-treated group was 0.52 (p <0.001), for elective stenting the hazard ratio was 0.51 (p <0.001), for bailout stenting the hazard ratio was 0.38 (p <0.001), and for directional coronary atherectomy the hazard ratio was 0.38 (p = 0.007). A Cox proportional-hazards model revealed that overall, the use of abciximab decreased the composite end point of 30-day death or MI rates (hazard ratio 0.55, 95% confidence interval 0.43 to 0.69, p <0. 001). However, bailout stenting and directional coronary atherectomy were associated with increased rates of death or MI compared with balloon angioplasty, as was elective stenting in women compared with men. There was no significant increase in major bleeding episodes associated with abciximab in any of the device categories. These findings from all the controlled coronary revascularization trials using abciximab demonstrate that a decrease in death and MI is achieved with abciximab regardless of the type of device used, without an increase in significant bleeding complications.

The use of glycoprotein IIb/IIIa inhibitor therapy in acute ST-segment elevation myocardial infarction: current practice and future trends.

The goal of therapy in acute myocardial infarction is complete and timely restoration of coronary blood flow. Current strategies for reperfusion fail to achieve ideal results and resolution of ischemia in all patients. The platelet plays a pivotal role in the pathophysiology of an acute myocardial infarction, and antiplatelet therapy has been shown to improve clinical outcomes. The final common pathway for platelet activation and aggregation in acute myocardial infarction is the activation of the glycoprotein (GP) IIb/IIIa receptor. Newer reperfusion strategies target the GP IIb/IIIa receptor, thereby preventing the prothrombotic effects of platelets in an acute myocardial infarction. In the past decade, several strategies targeting the use of GP IIb/IIIa inhibitors have been evaluated. GP IIb/IIIa inhibitors have been shown to improve angiographic Thrombolysis in Myocardial Infarction (TIMI) 3 flow rates when used as reperfusion therapy given with heparin and aspirin as compared with heparin and aspirin alone. When GP IIb/IIIa inhibitors are used with full-dose fibrinolytics, early studies have suggested a trend toward more rapid and more complete reperfusion in an acute myocardial infarction. Later trials have examined the use of GP IIb/IIIa inhibitors in conjunction with reduced-dose fibrinolytics. Results from TIMI 14 and Global Use of Strategies to Open occluded arteries-IV pilot trials support the use of combination therapy with reduced- dose fibrinolytics and the GP IIb/IIIa inhibitor abciximab. Given the promising role of GP IIb/IIIa inhibitor therapy in acute myocardial infarction, investigators questioned the need for concomitant antithrombin therapy. However, data from several investigations suggest that antithrombin therapy is required when GP IIb/IIIa inhibitors are used with fibrinolytics, although it appears that the dose of heparin may be reduced. Finally, recent investigations have addressed the safety and efficacy of facilitated early percutaneous intervention. In this strategy, patients presenting with an acute myocardial infarction are treated with reduced-dose fibrinolytics and GP IIb/IIIa inhibitors and are taken to the interventional cardiac catheterization laboratory within the first 60 minutes of therapy.

Abciximab reduces mortality in diabetics following percutaneous coronary intervention.

OBJECTIVES: We sought to determine whether abciximab therapy at the time of percutaneous coronary intervention (PCI) would favorably affect one-year mortality in patients with diabetes. BACKGROUND: Diabetics are known to have increased late mortality following PCI. METHODS: Data from three placebo-controlled trials of PCI, EPIC, EPILOG, and EPISTENT, were pooled. The one-year mortality rate for patients with a clinical diagnosis of diabetes mellitus was compared with the rate for nondiabetic patients treated with either abciximab or placebo. RESULTS: In the 1,462 diabetic patients, abciximab decreased the mortality from 4.5% to 2.5%, p = 0.031, and in the 5,072 nondiabetic patients, from 2.6% to 1.9%, p = 0.099. In patients with the clinical syndrome of insulin resistance--defined as diabetes, hypertension, and obesity--mortality was reduced by abciximab treatment from 5.1% to 2.3%, p = 0.044. The beneficial reduction in mortality with abciximab use in diabetics classified as insulin-requiring was from 8.1% to 4.2%, p = 0.073. Mortality in diabetics who underwent multivessel intervention was reduced from 7.7% to 0.9% with use of abciximab, p = 0.018. In a Cox proportional hazards survival model, the risk ratio for mortality with abciximab use compared with placebo was 0.642 (95% confidence interval 0.458-0.900, p = 0.010). CONCLUSIONS: Abciximab decreases the mortality of diabetic patients to the level of placebo-treated nondiabetic patients. This beneficial effect is noteworthy in those diabetic patients who are also hypertensive and obese and in diabetics undergoing multivessel intervention. Besides its potential role in reducing repeat intervention for stented diabetic patients, abciximab therapy should be strongly considered in diabetic patients undergoing PCI to improve their survival.

Early percutaneous coronary intervention, platelet inhibition with eptifibatide, and clinical outcomes in patients with acute coronary syndromes. PURSUIT Investigators.

BACKGROUND: Platelet glycoprotein (GP) IIb/IIIa antagonists prevent the composite end point of death or myocardial infarction (MI) in patients with acute coronary syndromes. There is uncertainty about whether this effect is confined to patients who have percutaneous coronary interventions (PCIs) and whether PCIs further prevent death or MI in patients already treated with GP IIb/IIIa antagonists. METHODS AND RESULTS: PURSUIT patients were treated with the GP IIb/IIIa antagonist eptifibatide or placebo; PCIs were performed according to physician practices. In 2253 of 9641 patients (23.4%), PCI was performed by 30 days. Early (<72 hours) PCI was performed in 1228 (12.7%). In 34 placebo patients (5.5%) and 10 treated with eptifibatide (1.7%) (P=0.001), MI preceded early PCI. In patients censored for PCI across the 30-day period, there was a significant reduction in the primary composite end point in eptifibatide patients (P=0.035). Eptifibatide reduced 30-day events in patients who had early PCI (11.6% versus 16.7%, P=0.01) and in patients who did not (14.6% versus 15.6%, P=0.23). After adjustment for PCI propensity, there was no evidence that eptifibatide treatment effect differed between patients with or without early PCI (P for interaction=0.634). PCI was not associated with a reduction of the primary composite end point but was associated with a reduced (nonspecified) composite of death or Q-wave MI. This association disappeared after adjustment for propensity for early PCI. CONCLUSIONS: Eptifibatide reduced the composite rates of death or MI in PCI patients and those managed conservatively.

Timing of and risk factors for myocardial ischemic events after percutaneous coronary intervention (IMPACT-II). Integrilin to Minimize Platelet Aggregation and Coronary Thrombosis.

We studied both the time course and risk factors for adverse clinical events after percutaneous coronary intervention (PCI). Such information is critical to clinical decision-making, but scant quantitative data exist to describe the time course of these adverse outcomes. Patients enrolled in the Integrilin to Minimize Platelet Aggregation and Coronary Thrombosis-II (IMPACT-II) trial were analyzed. Patients undergoing elective, urgent, or emergency PCI (n = 4,010) were randomized to receive either placebo or 1 of 2 eptifibatide regimens during intervention. We evaluated the time to the primary end point of the trial, the 30-day composite of death, myocardial infarction, repeat nonelective PCI, nonelective bypass surgery, or stenting for abrupt closure. Adverse events occurred in 407 patients (10.1%). Because the risk of events declined substantially between 6 and 9 hours (66% occurred within 6 hours), events were classified as occurring before or after 6 hours. Independent predictors of "early" events included dissection, pre- and postprocedural coronary blood flow, side-branch occlusion, procedural thrombolytic use, previous bypass, presentation with unstable angina, absence of diabetes, and hyperlipidemia. The predictors of "late" events included lower weight, increased baseline heart rate, coronary dissection, and procedural thrombolytic use. The risk of ischemic events were greatest immediately after PCI and rapidly declined, so that by 9 hours the hazard function plot was flat; 66% of events occurred within 6 hours of PCI. Knowledge of the risk factors for early and late events help risk-stratify patients before and after intervention for myocardial ischemic events.

Cost-effectiveness of platelet glycoprotein IIb/IIIa inhibition with eptifibatide in patients with non-ST-elevation acute coronary syndromes.

BACKGROUND: In the PURSUIT trial, eptifibatide significantly reduced the 30-day incidence of death and myocardial infarction relative to placebo in 9461 patients with an acute coronary syndrome (unstable angina or non-Q-wave myocardial infarction). METHODS AND RESULTS: We conducted a 2-part prospective economic substudy of the 3522 US patients enrolled in PURSUIT: (1) an empirical intention-to-treat comparison of medical costs (hospital plus physician) up to 6 months after hospitalization and (2) a lifetime cost-effectiveness analysis. The base-case cost-effectiveness ratio was expressed as the 1996 US dollars required to add 1 life-year with eptifibatide therapy. The 2 treatment arms had equivalent resource consumption and medical costs (exclusive of the cost of the eptifibatide regimen) during the index (enrollment) hospitalization (P=0.78) and up to 6 months afterward (P=0.60). The average wholesale price of the eptifibatide regimen was $1217, but a typical hospital discounted price was $1014. The estimated life expectancy from randomization in the US patients was 15.96 years for eptifibatide and 15.85 years for placebo, an incremental difference of 0.111. The incremental cost-effectiveness ratio for eptifibatide therapy in US PURSUIT patients was $16 491 per year of life saved. This result was robust through a wide range of sensitivity analyses. The cost-utility ratio for eptifibatide (using time trade-off defined utilities) was $19 693 per added quality-adjusted life-year. CONCLUSIONS: Based on the results observed in the US PURSUIT patients, the routine addition of eptifibatide to standard care for non-ST-elevation acute coronary syndrome patients is economically attractive by conventional standards.

The PRESTO (Prevention of restenosis with tranilast and its outcomes) protocol: a double-blind, placebo-controlled trial.

BACKGROUND: Tranilast is a unique drug in clinical development for the prevention of restenosis after percutaneous transluminal coronary revascularization (PTCR). Tranilast interferes with proliferation and migration of vascular medial smooth muscle cells induced by platelet-derived growth factor and transforming growth factor beta1. Collagen synthesis in vascular medial smooth muscle cells is inhibited by tranilast, which also inhibits the release or production of cyclooxygenase-2 and restores cytokine-induced nitric oxide production. These mechanisms may contribute to the reduction of angiographic restenosis after coronary intervention previously reported in clinical studies. METHODS: The primary objective of this multicenter study of 11,500 patients is to compare the composite clinical event rate of death, myocardial infarction, or the need for ischemia-driven target vessel revascularization of tranilast (300 and 450 mg twice daily) for 1 or 3 months with that of placebo in patients undergoing PTCR with or without stenting for single or multiple vessels over a 9-month period. The lesions can be de novo or restenotic. All revascularization procedures and the use of glycoprotein IIb/IIIa agents are permitted. The inclusion criteria are meant to allow an "all comer" approach for generalization of results to the broadest possible PTCR population. A subset population (n = 2000) will undergo 9-month follow-up angiography, 1000 of which will also undergo intravascular ultrasound (n = 1000). This study is the first tranilast trial to be conducted in a Western population to confirm the improved angiographic findings reported in Japanese patients and to determine if the clinical sequelae of restenosis are also reduced. CONCLUSION: This multicenter study is the largest restenosis trial planned to date. It will test whether tranilast, a drug with multiple actions aimed at affecting proliferation and migration of vascular smooth muscle cells, can reduce clinical, angiographic, and intravascular ultrasound assessments of restenosis.

Abciximab and bleeding during coronary surgery: results from the EPILOG and EPISTENT trials. Improve Long-term Outcome with abciximab GP IIb/IIIa blockade. Evaluation of Platelet IIb/IIIa Inhibition in STENTing.

BACKGROUND: Abciximab during percutaneous coronary revascularization reduces ischemic complications, but concern exists regarding increased bleeding risk should emergency coronary surgical procedures be required. METHODS: Outcomes were assessed among 85 patients who required coronary artery bypass grafting operations after coronary intervention in two randomized placebo-controlled trials of abciximab. Comparisons were made between patients in the pooled placebo and abciximab groups. RESULTS: The incidence of coronary surgical procedures was 2.17% and 1.28% among patients randomized to placebo and abciximab, respectively (p = 0.021). Platelet transfusions were administered to 32% and 52% of patients in the placebo and abciximab groups, respectively (p = 0.059). Rates of major blood loss were 79% and 88% in the placebo and abciximab groups, respectively (p = 0.27); transfusions of packed red blood cells or whole blood were administered in 74% and 80% of patients, respectively (p = 0.53). Surgical reexploration for bleeding was required in 3% and 12% of patients, respectively. Death and myocardial infarction tended to occur less frequently among patients who had received abciximab. CONCLUSIONS: Urgent coronary artery bypass grafting operations can be performed without an incremental increase in major hemorrhagic risk among patients on abciximab therapy.

Platelet glycoprotein IIb/IIIa receptor blockade in coronary artery disease.

New strategies for profound inhibition of platelet activity at the injured coronary plaque focus on blockade of the platelet surface membrane glycoprotein IIb/IIIa receptor, which binds circulating fibrinogen or von Willebrand factor and crosslinks platelets as the final common pathway to platelet aggregation. Intravenous agents directed against this receptor include the chimeric monoclonal antibody fragment abciximab, the peptide inhibitor eptifibatide and nonpeptide mimetics tirofiban and lamifiban. Over 33,000 patients have been evaluated in 11 large-scale, placebo-controlled trials of these agents. During percutaneous coronary intervention, an absolute reduction of 1.5% to 6.5% in the 30-day risk of death, myocardial infarction or repeat urgent revascularization has been observed, with some variability in treatment effect among the agents tested (abciximab, eptifibatide and tirofiban). Treatment effect is achieved early with every modality of revascularization and is maintained over the long-term (up to three years). Increased bleeding risk may be minimized by reduction and weight-adjustment of concomitant heparin dosing. In the acute coronary syndromes without ST segment elevation, absolute 1.5% to 3.2% reductions in 30-day rates of death or myocardial (re-) infarction have been achieved with two to four day courses of eptifibatide or tirofiban. Clinical benefit accrues during the period of drug infusion and is durable. Treatment effect may be enhanced among patients undergoing early coronary revascularization, with evidence of stabilization before intervention and suppression of postprocedural ischemic events. Thus, blockade of the platelet glycoprotein IIb/IIIa receptor reduces ischemic complications when used as an adjunct to percutaneous coronary intervention or the management of acute ischemic syndromes.

Clinical benefit of glycoprotein IIb/IIIa blockade with Abciximab is independent of gender: pooled analysis from EPIC, EPILOG and EPISTENT trials. Evaluation of 7E3 for the Prevention of Ischemic Complications. Evaluation in Percutaneous Transluminal Coronary Angioplasty to Improve Long-Term Outcome with Abciximab GP IIb/IIIa blockade. Evaluation of Platelet IIb/IIIa Inhibitor for Stent.

OBJECTIVES: We sought to determine the efficacy and safety of platelet glycoprotein IIb/IIIa receptor (GP IIb/IIIa) blockade with abciximab in women undergoing percutaneous coronary intervention. BACKGROUND: Although gender differences in response to platelet glycoprotein IIb/IIIa receptor blockade have been described, there have been no large clinical studies to assess these differences. METHODS: Outcomes were determined using meta-analysis technique. RESULTS: In the pooled analysis, the primary end point of death, myocardial infarction (MI) or urgent revascularization within 30 days was reduced from 11.3% to 5.8% (p<0.001) in men and from 12.7% to 6.5% (p<0.001) in women treated with abciximab. At six months, death, MI or urgent revascularization was reduced from 14.1% to 8.3% (p<0.001) in men and 16.0% to 9.9% (p<0.001) in women receiving abciximab. At one year, mortality was reduced from 2.7% to 1.9% (p = 0.06) in men and 4.0% to 2.5% (p = 0.03) in women treated with abciximab. Major bleeding events occurred in 2.9% versus 3.0% (p = 0.96) of women and 2.7% versus 1.3% (p = 0.003) of men treated with placebo versus abciximab, respectively. Minor bleeding events occurred in 4.7% versus 6.7% (p = 0.01) of women and 2.3% versus 2.2% (p = 0.94) of men treated with placebo versus abciximab, respectively. CONCLUSIONS: This pooled analysis demonstrated no gender difference in protection from major adverse outcomes with GP IIb/IIIa inhibition with abciximab. Although women had higher rates of both major and minor bleeding events with abciximab compared with men, major bleeding in women was similar with and without abciximab. There was a small increased risk of minor bleeding with abciximab in women.

Geographic variability in outcomes within an international trial of glycoprotein IIb/IIIa inhibition in patients with acute coronary syndromes. Results from PURSUIT.

AIMS: Variations in outcome of patients from different geographic regions have been observed in many large international trials. We analysed the factors that might contribute to the geographic variations in patient outcome and treatment effect as observed in the PURSUIT trial. METHODS: In PURSUIT, 9461 patients with acute coronary syndromes without persistent ST-elevation were randomized to the platelet inhibitor eptifibatide or placebo for 72 h in 27 countries in four geographic regions: Western (n=3697) and Eastern Europe (n=1541) as well as North (n=3827) and Latin America (n=396). The primary end-point was the 30-day composite of death or myocardial infarction. In the initial univariate analysis, the treatment effect appeared greater in N. America than in W. Europe, while no benefit was apparent in L. America and E. Europe. However, the confidence intervals were wide and overlapping. To study these differences, a subdivision in an early and late patient outcome and treatment effect was made. Accordingly, we analysed the rate of death or infarction at 72 h censored for percutaneous coronary intervention and the rate between 3 and 30 days, respectively. Additional analyses were performed with different definitions of myocardial infarction using progressively higher thresholds of CK(-MB) elevation. Multivariable analysis was used to evaluate the relation between region and outcome and to determine the adjusted odds ratios for the eptifibatide treatment effect. RESULTS: Major differences in baseline demographics were apparent among the four regions; in particular, more patients from E. Europe had characteristics associated with impaired outcome. Interventional treatment also varied considerably, with more patients from N. America undergoing revascularization. Despite differences in the 72 h event rate, eptifibatide showed a consistent trend towards a reduction in the composite end-point among all four regions and for all definitions of infarction. Relative reductions ranged from 17-42% in W. Europe, 23-35% in N. America, 0-33% in E. Europe, and 55-82% in L. America. After multivariable adjustment, the pattern of benefit with eptifibatide was consistent among the regions. In patients undergoing percutaneous coronary intervention during study drug infusion in W. Europe (n=266) and N. America (n=931), the relative reduction in myocardial infarction during medical therapy ranged from 56-75% in W. Europe and 14-67% in N. America, while the reduction in procedure-related events ranged from 12-44% and 25-61% for different definitions of infarction. After multivariable adjustment neither benefit nor rebound were apparent after study drug discontinuation, or after 3 days in all regions, except in L. America. In general, the differences in outcome and treatment effect were greatest when the protocol definition of myocardial infarction (CK(-MB) >1 upper normal limit) was applied. Under stricter definitions, these differences became smaller and disappeared with the investigator's assessment. CONCLUSION: The analysis suggests that the apparent differences in patient outcome and eptifibatide treatment effect can be explained largely by differences in baseline demographics and adjunctive treatment strategies as well as by the methodology of myocardial infarction definition and the adjudication process.

Clinical correlates and course of thrombocytopenia during percutaneous coronary intervention in the era of abciximab platelet glycoprotein IIb/IIIa blockade.

BACKGROUND: Thrombocytopenia is infrequently associated with abciximab therapy but may contribute to hemorrhagic risk. Factors associated with development of thrombocytopenia, the role of weight-adjustment in concomitant heparin administration, and clinical outcomes in patients with thrombocytopenia are not well defined. METHODS AND RESULTS: Pooled data from 3 placebo-controlled, randomized trials (EPIC, EPILOG, and EPISTENT) of abciximab therapy during percutaneous coronary intervention identified 178 patients (2. 4% of 7290 patients) in whom thrombocytopenia (platelet count <100 x 10(9)/L) developed after enrollment. Multivariate regression analysis identified age (>65 years; P <.001), weight (<90 kg; P =. 023), baseline platelet count (<200 x 10(9)/L; P <.001), abciximab therapy (P =.002), and enrollment into the EPIC trial (P <.001) to be associated with development of thrombocytopenia. Major and minor nonsurgical hemorrhage and transfusion were more frequent (all P <. 001) in thrombocytopenic patients. Although the primary composite clinical end point of these trials (death, myocardial infarction, or urgent revascularization to 30 days) was observed with similar frequency in patients with (11.2%) and those without (7.9%; P =.114) thrombocytopenia, 30-day mortality rate was higher in thrombocytopenic patients (8.4% vs 0.6%, respectively; P <.001). This excess mortality rate persisted after excluding patients in whom thrombocytopenia was first noted after the performance of coronary bypass surgery (4.8% vs 0.6%; P <.001). Among patients in whom thrombocytopenia developed during these trials, those who received prophylactic abciximab had fewer primary end point events (7.1% vs 23.1%; P =.056) and had a lower 30-day mortality rate (3.5% vs 15.4%; P =.048) than patients with thrombocytopenia who had received prophylactic placebo. CONCLUSIONS: Thrombocytopenia associated with abciximab therapy for percutaneous coronary intervention was more frequent in older, lighter-weight patients, those with lower baseline platelet counts, and in those patients who were enrolled into the EPIC trial. Both bleeding and transfusion events occur more frequently in patients with thrombocytopenia. Patients in whom thrombocytopenia developed during these trials had increased mortality rates to 30 days not attributable to the performance of coronary bypass surgery. Among patients with thrombocytopenia, those who received prophylactic abciximab had better clinical outcomes including survival than those who did not.

Glycoprotein IIb/IIIa inhibitors in acute coronary syndromes.

Glycoprotein (GP) IIb/IIIa inhibitors are potent antiplatelet agents and represent an exciting breakthrough in the treatment of acute coronary syndromes. However, their safety and cost-effectiveness require further investigation, and more information on risk stratification is needed to clarify which patients benefit the most from empiric use of these agents.

Outcomes at 1 year and economic implications of platelet glycoprotein IIb/IIIa blockade in patients undergoing coronary stenting: results from a multicentre randomised trial. EPISTENT Investigators. Evaluation of Platelet IIb/IIIa Inhibitor for Stenting.

BACKGROUND: We assessed in a randomised trial the long-term outcomes for potent adjunctive antiplatelet therapy given at the time of coronary stenting. METHODS: In 63 hospitals in the USA and Canada, 2399 patients were randomly assigned stenting with abciximab, stenting with placebo, or balloon angioplasty with abciximab. Standard adjunctive therapy with aspirin, ticlopidine, and heparin was used. The major outcomes of death and myocardial infarction were assessed at 1-year follow-up by intention to treat. We also investigated the 1-year cost-effectiveness of combined stenting and abciximab therapy. FINDINGS: At 1-year follow-up, eight (1.0%) of 794 patients in the stent plus abciximab group had died, compared with 19 (2.4%) of 809 in the stent plus placebo group (hazard ratio 0.43 [95% CI 0.19-0.97], p=0.037). The combined endpoint of death or large myocardial infarction occurred in 42 (5.3%) and 89 (11.0%), respectively (0.46 [0.32-0.67], p<0.001). By multivariate modelling, the factors independently associated with improved survival were assignment to stenting with abciximab (p=0.027) and greater preprocedural stenosis (p=0.002); those associated with worse survival were age greater than 70 years (p<0.001), previous heart failure (p=0.001), diabetes treated with insulin (p=0.02), and postprocedural occlusion (p<0.001). Relative to stenting plus placebo and balloon angioplasty plus abciximab, the incremental 1-year costs of stenting plus abciximab were US$581 and $932. The corresponding cost-effectiveness ratios were US$5291 and $6213 per added life-year. INTERPRETATION: Coronary stenting with abciximab, compared with stenting alone or balloon angioplasty with abciximab, is associated with improved survival and is an economically attractive therapy by conventional standards.
