Clinical Trial Summary

To examine the impact of IVUS guidance on clinical outcomes in the patient with Acute ST Segment Elevated Myocardial Infarction.

Description:

Intravascular ultrasound (IVUS) has been increasingly used as a guide for percutaneous coronary intervention (PCI) during elective as well as emergent clinical scenario. Recent small number randomized studies, large scale registries as well as meta-analysis have consistently demonstrated advantages of IVUS-guidance over angiography-guide alone with respect to the lower incident of death, myocardial infarction and target vessel revascularization. There are sparse data available on the clinical impact of IVUS-guided PCI in the setting of acute myocardial infarction (AMI) and its use remains a matter of controversy as shown by previous studies. This study is to examine the impact of IVUS guidance on clinical outcomes in the patient with Acute ST Segment Elevated Myocardial Infarction (STEMI).
