ABSTRACT
Objective:To investigate the relationship of von Willebrand factor cleaving enzyme(ADAMTS-13), ratio of mean platelet volume to platelet count (MPV/P), intelectin-1 (ITLN-1) and thrombolysis in myocardial infarction (TIMI) blood flow classification in acute myocardial infarction patients who performed percutaneous coronary intervention(PCI) and the value of predicting postoperative major cardiovascular adverse events (MACE).Methods:A total of 126 patients with acute myocardial infarction treated with PCI in Yuechi County People′s Hospital from January 2019 to January 2021 were selected and divided into MACE group (25 cases) and no MACE group (101 cases) according of the prognosis. The levels of ADAMTS-13, MPV/P and ITLN-1 were compared between the two groups, the correlation of above index and TIMI blood flow classification and the value of predicting postoperative MACE were analyzed.Results:The levels of ADAMTS-13 and ITLN-1 in the MACE group were lower than those in the MACE group, and the level of MPV/P was higher than that in the MACE group: (132.59 ± 43.05) μg/L vs. (186.33 ± 58.17) μg/L, (255.36 ± 80.24) mg/L vs. (342.65 ± 91.18) mg/L, (0.06 ± 0.02) fl/( × 10 9/L) vs. (0.04 ± 0.01) fl/( ×10 9/L), there were statistical differences ( P<0.05). The results of Spearman correlation analysis showed that the levels of ADAMTS-13 and ITLN-1 were positively correlated with TIMI blood flow classification ( r = 0.692, 0.622, P<0.01) , the level of MPV/P was negatively correlated with TIMI blood flow classification ( r = -0.665, P<0.01). The area under the curve of ADAMTS-13, MPV/P combined with ITLN-1 in protecting the MACE was 0.872. Conclusions:ADAMTS-13, MPV/P and ITLN-1 are related to the TIMI blood flow classification and MACE in patients with acute myocardial infarction after PCI, and the combined detection can be used as a reliable predictor of MACE.
