AIMS: In the HORIZONS-AMI trial, bivalirudin compared to unfractionated heparin (UFH) plus a glycoprotein IIb/IIIa inhibitor (GPI) improved net clinical outcomes in patients undergoing primary percutaneous coronary intervention (PCI) at the cost of an increased rate of acute stent thrombosis. We sought to examine whether these effects are dependent on time to treatment. METHODS AND RESULTS: The interaction between anticoagulation regimen and symptom onset to first balloon inflation time (SBT) on the 30-day and three-year rates of major adverse cardiac events (MACE) was examined in 3,199 randomised patients according to SBT ≤3 hours versus >3 hours...

BACKGROUND: The use of antithrombotic therapy (ATT) (bivalirudin or unfractionated heparin) is a class I recommendation for patients undergoing primary percutaneous coronary intervention (PPCI) for ST-segment elevation myocardial infarction (STEMI). This survey was conducted to better understand current United States (US) practices in terms of preferences regarding the selection of ATT in STEMI-PPCI, particularly in light of recent clinical trials. METHODS: An electronic survey consisting of 9 focused questions was forwarded to 2676 US interventional cardiologists who were members of the Society for Cardiovascular Angiography and Interventions (SCAI)...

Bivalirudin, a direct thrombin inhibitor, was developed as an antithrombin agent for patients undergoing percutaneous coronary interventions (PCI) with the hypothesis that it would reduce bleeding complications without compromising the rate of ischemic events compared to heparin plus GP IIb/IIIa inhibitors. Although the cumulative evidence makes a strong argument for the use of bivalirudin rather than heparin plus systematic GP IIb/IIIa inhibitors for the great majority of patients with acute myocardial infarction (AMI) undergoing PCI, the benefit observed with bivalirudin was achieved because of the major bleeding complications with the use of heparin plus GP IIb/IIIa inhibitors...

INTRODUCTION: Bivalirudin, has been shown to have comparable efficacy and better safety profile when compared to unfractionated heparin (UFH) in percutaneous coronary interventions. Bivalirudin's safety in carotid artery stenting (CAS) was associated with better outcomes than heparin in some studies. In this Meta analysis we examine the hemorrhagic and ischemic outcomes associated with Bivalirudin compared to UFH during CAS. METHODS: A comprehensive literature search was conducted with the electronic databases MEDLINE, EMBASE, and CENTRAL...

BACKGROUND: Clinical trials have demonstrated an excess of acute stent thrombosis (AST) in acute coronary syndromes patients (ACS) undergoing percutaneous coronary intervention (PCI) with bivalirudin compared to heparin. We aimed to investigate the potential mechanisms responsible for thrombus formation under bivalirudin. METHODS: We compared heparin and bivalirudin during PCI for ACS in a prospective monocentre randomized study. Twenty patients were included after coronary angiography and received a loading dose (LD) of 180mg of ticagrelor at the time of PCI...

OBJECTIVES: The aim of this study was to evaluate the efficacy of various doses of post-primary percutaneous coronary intervention (PCI) bivalirudin infusion to prevent acute stent thrombosis (AST). BACKGROUND: In several recent randomized controlled trials, bivalirudin infusion was continued post-PCI as either a full PCI dose (Biv-Full) or a reduced dose (Biv-Low) to reduce the risk for AST. The results of these trials varied, so the authors performed a meta-analysis of RCTs to determine whether the risk for AST is dose dependent...

The CARTAGOMAX study assessed the safety and efficacy of bivalirudin during real-world cardiac intervention. This was a single-center prospective study. Patients with acute coronary syndrome undergoing percutaneous coronary intervention were anticoagulated with bivalirudin alone or unfractionated heparin plus a glycoprotein IIb/IIIa inhibitor. Propensity score matching was performed to control for baseline imbalances and yielded 1168 patients. There was lower incidence of the composite outcome of death from any cause or major bleeding at 30 days (P = 0...

BACKGROUND: The optimal anticoagulant for patients with acute coronary syndrome treated with percutaneous coronary intervention (PCI) has not been validated in current practice of radial approach and pretreatment with potent P2Y12 inhibitors. Several studies have indicated increased bleeding rate and, in some instances, even increased mortality by the routine use of heparin and glycoprotein IIb/IIIa inhibitors compared to bivalirudin. Direct comparison of bivalirudin versus heparin alone has yielded contradictory results depending on study designs...

BACKGROUND: Early stent thrombosis (ST) within 30 days after primary percutaneous coronary intervention in ST-segment-elevation myocardial infarction is a serious event. We sought to determine the predictors of and risk of mortality after early ST according to procedural antithrombotic therapy. METHODS AND RESULTS: In a patient-level pooled analysis from the Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction (HORIZONS-AMI) and European Ambulance Acute Coronary Syndrome Angiography (EUROMAX) trials, we examined 30-day outcomes in 4935 patients undergoing primary percutaneous coronary intervention with stent implantation at 188 international sites, randomized to either bivalirudin or heparin±a glycoprotein IIb/IIIa inhibitor (GPI)...
