  1. Population characteristics are shown as mean ± SD or valid per cent. CMR values of MaR and infarct are expressed as % of LVM while MSI is expressed as % of MaR
  2. aReliable data on whether a patient received oxygen in the acute phase of ischemia was only available for patients included in the SOCCER trial (n = 95). Pre PCI TnT < 15 ng/L = a blood sample acquired before coronary intervention showing a troponin T value < 15 ng/L, TRO40303 = the study treatment in the mitocare trial
  3. LVM left ventricular mass, BSA body surface area, MaR myocardium at risk, MSI myocardial salvage index
