Notes: High NLR = NLR > 6.69; High PLR = PLR >187.6; Type of AMI includes NSTEMI and STEMI, Non-ST-segment elevation myocardial infarction was used as a reference.
Abbreviations: NLR, neutrophil-lymphocyte ratio; PLR, platelet-lymphocyte ratio; AMI, acute myocardial infarction; BMI, body mass index; CTNI, cardiac troponin I; CK-MB creatine kinase-MB; eGFR, estimated glomerular filtration rate.
