AMI leads to αβ T cells activation. Peripheral blood samples were obtained from 30 healthy controls and 30 AMI patients. a The count of WBC was measured from peripheral blood samples. The percentage of neutrophils (b), lymphocytes (c), monocytes (e) was detected by Sysmex XN in our clinical laboratory. d The correlation between cTnI level and lymphocytes was calculated in AMI patients. Spearman’s correlation coefficient r = − 0.5874, P = 0.0006 (n = 30). f The percentage of αβ T cells from peripheral blood was analyzed by flow cytometry. g αβ T cells were gated and tested for expression of CD69
