Electro-mechanical characteristics of myocardial infarction border zones and ventricular arrhythmic risk: Novel insights from grid-tagged cardiac magnetic resonance imaging

Objective To investigate whether grid-tag myocardial strain evaluation can characterise ‘border-zone’ peri-infarct region and identify patients at risk of ventricular arrhythmia as the peri-infarct myocardial zone may represent an important contributor to ventricular arrhythmia following ST-segment elevation myocardial infarction (STEMI).
