Fig 1. Strain-pressure loop and GLS changes during coronary occlusion.
Example of changes in Myocardial Work Index (MWI) and global longitudinal strain (GLS) at baseline, during transient coronary occlusion and after PCI. GLS: Global longitudinal strain. MWI: Myocardial work index. LAD: Left anterior descendent coronary artery. TACO: Transient acute coronary occlusion. PCI: Percutaneous coronary intervention.
