Comparison of Primary PCI vs. Post-thrombolysis PCI as Reperfusion Strategies in STEMI (GRACIA4)
Myocardial Infarction
About this trial
This is an interventional treatment trial for Myocardial Infarction focused on measuring primary angioplasty, post-thrombolysis angioplasty, ST elevation acute myocardial infarction
Eligibility Criteria
Inclusion Criteria:
- Age >18 years
- Chest discomfort > 30 minutes with no response to nitroglycerin
- Time from the onset of symptoms to randomization between 0 and 12 hours
- ST segment elevation > 1 mm in two or more contiguos precordial leads or non-diagnostic ECG (left bundle branch block or pacemarker rhythm) with classic symptoms.
- Killip class equal or less than 3
- Written informed consent
Exclusion Criteria:
- Cardiogenic shock defined as a systolic blood pressure <90 mm Hg without response to fluid administration or <100 mm Hg in patients with supportive treatment and no bradycardia
- Suspicion or evidence of mechanical complications of STEMI
- Non-cardiac disease that is likely to jeopardize compliance with follow-up schedule of the study (life expectancy < 1 year)
- woman of childbearing potential unless a negative pregnant test
- Major contraindications for thrombolytic therapy
- Participation in other trial
- Known multivessel disease identified as unsuitable for revascularization
- Known peripheral vascular disease that complicates cardiac catheterization

Primary angioplasty
Post-thrombolysis angioplasty
Patients assigned to this treatment will undergo cardiac catheterization within the time recommended by current guidelines. Double antiagregation will be used, vascular access wil be obtained and bivalirudin will be used as anticoagulation; all following current guidelines recommendations
Patients will receive tenecteplase, enoxaparin, and double antiagreagation with clopidogrel or aspirin as recommended guidelines. Criteria of no reperfusion after fibrinolysis is defined as absence of ST-segment lowering >50%, 90 minutes after fibrinolysis. If not reperfusion is achieved recue angiplasty will be performed inmmediately if reperfusion is achieved cardiac catheterization will be performed the mornig following the day of randomization
