Evaluation of complete blood count parameters in patient with acute myocardial infarction over 80 years of age and under 40 years of age Elderly, complete blood count, acute myocardial infarction

Abstract

Aim: In our study, we compared the values of whole blood count (CBC) parameters, neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) parameters of patients over 80 years and under 40 years of age with acute myocardial infarction (AMI). Material and Method: We performed a retrospective study between 2011 and 2016 by screening the files of AMI patients who underwent primary percutaneous coronary intervention. A total of 259 patients under 40 years of age (Group 1) and over 80 years of age (Group 2) were included in the study. Results: When the hematological parameters were examined, white blood cell (WBC), neutrophil, lymphocyte, thrombocyte, hemoglobin, hematocrit numbers were found to be significantly higher in Group 1 patients. When PLR and NLR were examined (105.8 +/- 67.6 & 149.2 +/- 94; p <0.001, 3.2 +/- 3.2 & 42 +/- 4.4, p < 0.074 respectively), PLR was significantly higher in group 1. When the age was correlated with hematological and biochemical parameters, there was a significant negative correlation with WBC, neutrophil, lymphocyte, and platelet, was and a positive correlation with PLR, NLR. red blood cell distribution width (RDW), Gensini score and creatinine. Discussion: In elderly patients over 80 years, the hematological response of cells to acute events such as AMI was reduced due to the decreased bone marrow function.
