Representative images of LGE CMR and coronary anatomy at the start of angiography in the cohorts. Top row: CMR late gadolinium images from a patient within each of the 5 study cohorts, demonstrating infarct (enhancement); microvascular obstruction (arrow) evident as hypointense areas within infarct. Middle row: coronary angiography images at the start of angiography in the same patients demonstrating infarct related artery; white star denotes culprit lesion (right coronary artery in PPCI and lysis patient, left circumflex in rescue-PCI patient, left anterior descending artery in late PCI and non-reperfused patient). Bottom row: Time from symptoms to revascularisation (TTR) and CMR data for the same patients.
