NETosis and non-ST elevation acute myocardial infarction: pathophysiological significance and circulating markers
Keywords:NETosis, NSTEMI, circulating markers
Purpose. Evaluation of the role of neutrophil death (NET-osis) in the evolution of non-ST-segment elevation myocardial infarction (NSTEMI) by assessing circulating levels of in-patient admission of markers that are pathophysiologically related to this phenomenon. Material and methods. The research was carried out on a group of 54 patients with NSTEMI, undergoing coronary angioplasty in the laboratory of interventional cardiology within the scientific project of the State Program, in which the serum content of 7 biochemical markers was determined by the ELISA method: Selectin E, the molecule of intercellular adhesion 1 (ICAM-1), phospholipase 2 (PhA2), interleukin 8 (IL-8), neutrophil elastase (EN), myeloperoxidase (MPO) and metalloproteinase 8 (MMP-8). The control group consisted of 30 apparently healthy people. Results. The obtained results indicate the presence of significant incremental deviations of all explored markers in patients with NSTEMI compared to the control. The more specific markers of NETosis (MPO, NE and MMP-8) had a highest raising ratio, detected in a range of 88-151%. The other markers had a rate of circulating levels increase in a range of 50-74%. Conclusion. The admission circulating levels of specific markers of NETosis, myeloperoxidase, neutrophil elastase and MMP-8 are elevated in patients with NSTEMI by 88-151% compared to control, evidence, that indicates the pathogenetic role of NETosis as well as the plausible diagnostical and prognostical value of these markers.
