Abstract

1036 Semi-quantitative segmental scores is an accurate method in determing the size and extent of acute myocardial infarction

Highlights

  • As increasing numbers of subjects undergo cardiac magnetic resonance (CMR) imaging to determine myocardial salvage and viability following acute myocardial infarction (AMI), a simple and robust method to portray the extent and severity of necrotic myocardium is clinically necessary to aid rapid communication, monitor therapies and predict cardiovascular outcomes

  • We examined the predictive accuracy of semi-quantitatively scoring wall function and hyperenhancement in patients following an AMI

  • A total of 2074 segments were available for analysis with 36% of these segments (n = 756 segments) showing evidence of HE on viability images

Summary

Introduction

As increasing numbers of subjects undergo cardiac magnetic resonance (CMR) imaging to determine myocardial salvage and viability following acute myocardial infarction (AMI), a simple and robust method to portray the extent and severity of necrotic myocardium is clinically necessary to aid rapid communication, monitor therapies and predict cardiovascular outcomes. The American Heart Association published guidelines on the use of a 17-segment model to aid this communication amongst various imaging modalities.
