Direct Complete Versus Staged Complete Revascularization in Patients Presenting With Acute Coronary Syndromes and Multivessel Disease

Inclusion Criteria: Inclusion criteria STEMI-ACS ST-segment elevation myocardial infarction (STEMI) Both criteria must be present for eligibility * Chest pain for more than 20 minutes with an electrocardiographic ST-segment elevation of 1 mm or greater in two or more contiguous leads, or with a new left bundle-branch block * Admission either within 12 hours of symptom onset or between 12 and 24 hours after onset with evidence of continuing ischemia. Inclusion criteria for NSTE-ACS Non-ST-segment elevation myocardial infarction (NSTEMI) At least two of the following must be present for eligibility * History consistent with new, or worsening ischemia, occurring at rest or with minimal activity * Coronary angiography with indication to PCI * Troponin T or I or creatine kinase MB above the upper limit of normal * Electrocardiographic changes compatible with ischemia but not diagnostic for ST-segment elevation myocardial infarction (i.e. ST depression of 1 mm or greater in two contiguous leads, T-wave inversion more than 3 mm, or any dynamic ST shifts) 0 Unstable Angina (UA) At least two of the following must be present in the absence of cardiomyocyte necrosis (i.e. Troponin T or I and creatine kinase MB must be within normal limits): * History consistent with new, or worsening ischemia, occurring at rest or with minimal activity * Coronary angiography with indication to PCI * Electrocardiographic changes compatible with ischemia but not diagnostic for ST-segment elevation m…
