Incidence of target vessel failure (TVF) at 1 year follow-up (according to ARC definitions). Components of the primary endpoint in hierarchical order: - Cardiac death: all deaths are considered cardiac, unless an unequivocal non-cardiac cause can be established. - Target vessel related myocardial infarction (MI) that is Q-wave or non-Q-wave, that can be related to the target vessel or cannot be related to another vessel. - Clinically driven repeated target vessel revascularization by means of PCI or coronary artery bypass grafting (CABG).
