Study design. (a) The study population comprised 5 groups of pigs (n = 5/group). Groups 1 to 5 were used for the histopathological characterization of myocardial tissue changes during the first week after ischemia/reperfusion (I/R). CMR (cardiac magnetic resonance) scans included cine steady-state free-precession (SSFP) sequences to provide high quality anatomical references and functional information. CMR scans were performed at all follow-up stages until sacrifice, so that animals sacrificed at day 7 underwent baseline, 120 min, 24 h, day 4, and day 7 CMR. CMR and myocardial water content data from animals in groups 1 to 5 have been reported previously18. (b) For proteomic analysis, remote and ischemic tissue samples from these animals were processed for protein extraction, tryptic digestion, multiplexed stable isotope labeling, and fractionation followed by nano-liquid chromatography-tandem mass spectrometry (nanoLC-MS/MS) and systems biology analysis.
