Objectives
Narrative objectives1
To clarify the effectiveness of excimer laser coronary angiplasty (ELCA) on myocardial salvage in patients with anterior STEMI evaluated by nuclear scintigraphy (BMIPP 3-9 days after p-PCI and Tc99m-tetrofosmin at 6 months after p-PCI)

Assessment
Primary outcomes
myocardial salvage = (Risk at area measured by BMIPP 3-9 days after p-PCI) - (Infarct size measured by Tc99m-tetrofosmin at 6 months after p-PCI)
myocardial salvage index (%) = myocardial salvage / Risk at area measured by BMIPP 3-9 days after p-PCI x 100
Key secondary outcomes
Myocardial salvage, infarct size, microvascular obstruction by MRI
Left ventricular ejection fraction by TF scintigraphy at 6 months
12 months, 36 months, 60 months Clinical end point
Intra-stent tissue volume by OCT
