Persistent diastolic dysfunction despite complete systolic functional recovery after reperfused acute myocardial infarction demonstrated by tagged magnetic resonance imaging

Abstract

Reversibly injured regions can demonstrate persistent diastolic dysfunction despite complete systolic functional recovery after reperfused AMI. Moreover, the presence of no-reflow entails profound systolic and diastolic dysfunction. Finally, tagged magnetic resonance imaging (MRI) strain rate analysis provides detailed mechanical characterisation of regions with different degrees of myocardial ischaemic injury.
