Brief Summary:
The conceptual hypothesis of this study is that primary angioplasty is superior to a combined strategy of immediate thrombolysis followed by routine angioplasty in patients with ST-segment elevation acute myocardial infarction (STEMI), even with the inherent delay of the transfer of these patients.
Detailed Description:
This is a randomized, multicenter, open-label clinical trial comparing two strategies of reperfusion in STEMI. Patients will be randomly allocated to: primary angioplasty or post-thrombolysis angioplasty. A clinical follow-up will be performed at 12 months. In this trial, 1444 patients with STEMI will be randomized to primary angioplasty with immediate stent implantation in at least the infarct related artery (IRA) under bivalirudin protection, or to a combined strategy of immediate thrombolysis with tenecteplase (TNK) and enoxaparin followed by cardiac catheterization and adequate revascularization when indicated during the next morning after randomization.
Primary endpoint:
To compare the clinical efficacy (incidence of the composite endpoint formed by death, reinfarction, new revascularization, rehospitalization or severe hemorrhage within 12 months) of primary angioplasty versus thrombolytic treatment followed by percutaneous coronary intervention (PCI) the next day in patients with STEMI.
Secondary endpoints:
* Components of the composite endpoint individually analysed at 12 months (death, reinfarction, new revascularization, rehospitalization and severe hemorrhage).
* Cardiovascular mortality and its different components (pre-specified in the case report forms, CRF) at 12 months.
* Incidence of the composite endpoint formed by death, reinfarction, new revascularization, rehospitalization and/or hemorrhage at 30 days.
* Incidence of major bleeding events during hospitalization and at 30 days.
* To compare the clinical efficacy of both treatments according to the timing of presentation after symptom onset (0 to 3 hours, \>3-6 hours, and \>6-12 hours), to the patient´s age (\> or \< 75 years), to the infarction localization (anterior or inferior), to gender (male or female), to the presence of diabetes mellitus and to the characteristics of the recruiting center (with or without 24-hour catheterization facilities).
* Incidence of the composite endpoint formed by death, reinfarction, new revascularization, rehospitalization and/or hemorrhage at 3 years.
* Components of the composite endpoint individually analysed at 3 years (death, reinfarction, new revascularization, rehospitalization and severe hemorrhage).
* Analysis of stent thrombosis according to the Academic Research Consortium (ARC) definition (http://www.fda.gov/ohrms/dockets/ac/06/transcripts/2006-4253t2.rtf.) within 30 days, 12 months and 3 years.
* To compare the combination of death, reinfarction, revascularization, rehospitalization and/or major hemorrhage of patients treated with primary angioplasty versus those assigned to the postrombolysis angioplasty who underwent catheterization the following day within 30 days, 12 months and 3 years.
* To compare every indivicual components of the combine endpoint (death, reinfarction, revascularization, rehospitalization and major hemorrhage) of patients treated with primary angioplasty versus those assigned to the postrombolysis angioplasty who underwent catheterization the following day within 30 days, 12 months and 3 years.
* To compare the cost-effectiveness relationship (cost of maintaining a patient alive and without adverse cardiovascular events within the first year post-infarction) of both strategies.
