Coronary Artery Disease
Conditions
Brief summary
Hypothesis: the clinical outcome of patients with indication of PCI and coronary stent implantation that are at high risk of events can be improved with a widespread use of intra-coronary tools that allow a PCI optimization (i.e. functional assessment by pressure guidewire and intra-coronary imaging techniques). Objective: to evaluate whether the use of pressure guidewire and intra-coronary imaging techniques (mainly optimal coherence tomography) in patients at high risk of events undergoing coronary angiography for myocardial revascularization is associated with an improved clinical outcome in comparison with patient with angiographic alone guided cobalt-chromium everolimus-eluting coronary stenting. Methods: Prospective observational multicentric international study with a follow-up of 12 months, including 1.000 patients in 40 sites located in 3 European countries (Spain, France, and Portugal). The control group will be comprised by a similar number of matched patients included in the extended-risk cohort of the XIENCE V USA study. PCI will be performed following local standard protocols and accordingly to the physician criteria. The use of pressure guidewire will be recommended according to the current guidelines, in patients with angiographically intermediate lesions and in those with multivessel disease. The use of OCT will be strongly recommended, as patients included will be considered to be at high risk of events, accordingly to the current recommendations. The primary endpoint will be target lesion failure (TLF) at 1 year.

Inclusion criteria
* At least one of the following high-risk characteristics: lesion length \> 28 mm; reference vessel diameter \< 2.5 mm or \> 4.25 mm; chronic total occlusion; bifurcation with side branch ≥ 2 mm; ostial lesion; left main; in-stent restenosis; more than 2 lesions stented in the save vessel; more than 2 vessels treated; acute myocardial infarction; renal insufficiency; ejection fraction \< 30%; or staged procedure.
