The serum level of LL-37 is reduced in patients with myocardial infarction. a The serum level of the human cathelicidin LL-37 was measured by ELISA in patients with myocardial infarction (MI, n = 172) and normal controls (n = 160). b The serum level of LL-37 was measured by ELISA in MI patients with cardiovascular readmission and/or death (n = 27) compared to those without readmission and/or death (n = 53) during the 1-year follow-up. c The serum LL-37/neutrophil ratio was determined in MI patients with cardiovascular readmission and/or death (n = 27) compared to those without readmission and/or death (n = 53) during the 1-year follow-up. d The receiver-operator characteristic (ROC) curve was used to assess the sensitivity and specificity of the serum LL-37/neutrophil ratio in prediction of readmission and/or death in MI patients. Data were expressed as mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001
