Histological and electrocardiography (ECG) parameters. (a) Representative gross images of whole hearts. (b) Representative of 1% triphenyl tetrazolium chloride (TTC) staining results. (c) Representative of 2-lead electrocardiogram results. (d) Arrhythmia was scored according to 2-lead electrocardiogram. Model-2 h group (after 30 min of myocardial ischemia, reperfusion 2 h), Model-4 h group (reperfusion for 2 h after 30 min of myocardial ischemia), Model-4 h group (reperfusion for 4 h after 30 min of myocardial ischemia), HZOL-2 h group (application of HZOL before Model-2 h), HZOL-4 h group (application of HZOL before Model-4 h), isosorbide mononitrate capsule (ISMOC)-2 h group (application of ISMOC before Model-2 h), ISMOC-4 h group (application of ISMOC before Model-4 h), and sham group (subjected to the same surgical procedure in the absence of left anterior descending coronary artery). versus sham group; versus Model-2 h group; versus Model-4 h group.
