Background: Intravascular ultrasound (IVUS)-guided stent implantation has been provided favorable clinical outcomes in patients with angina pectoris. However, the efficacy of this strategy is not well known during primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods: We prospectively analyzed 135 AMI patients underwent primary PCI. All patients were divided into 2 groups: Group 1 IVUS guided stenting, Group 2 angiography guided stenting. The clinical outcomes (include death, non-fatal myocardial infarction, target vessel revascularization) were evaluated at 6 months follow-up. At 6 months follow-up coronary angiography was also performed 30 of 72 patients (42%) in group 1, 30 of 63 patients (48%). Results: See as a following table. Conclusion: Although immediate procedural results were favorable, an IVUS-guided stenting during primary PCI did not show favorable clinical outcomes as well as angiographic restenosis at 6 month follow-up.
