No results posted yet for this study

Summary

1. to investigate the feasibility and diagnostic performance of contrast quantitative flow ratio (QFR) for identifying the functional significance of intermediate degree stenotic lesions in all-comer patients with coronary artery disease (CAD) including presentation of acute myocardial infarction (AMI) with non-culprit lesion.
2. to compare the changes of contrast QFR and fractional flow reserve (FFR) according to severity of percent diameter stenosis (%DS)
3. to evaluate prognostic implication of contrast QFR in comparison with FFR

Conditions

  • Ischemic Heart Disease

Interventions

DIAGNOSTIC_TEST

QFR assessment

QFR measurement in order to evaluate functional significance of epicardial stenosis and to compare the response of QFR for worsening stenosis severity, FFR value as reference standard
