Abstract:
Objective:To investigate the value of peripheral blood platelet to gamma-glutamyl transferase ratio (PLT/GGT) in evaluating plaque stability recognized by virtual histology-intravascular ultrasound (VH-IVUS) in patients with coronary heart disease.Methods:This study was a prospective study. A total of 100 patients with coronary heart disease admitted in Zhejiang Veteran Hospital/the Third Affiliated Hospital of Jiaxing University from June 2020 to December 2022 were included. They were divided into vulnerable plaque group (42 cases) and stable plaque group (58 cases) based on the stability of the plaque examined by VH-IVUS. The general data, PLT/GGT and other laboratory indexes were compared between the two groups. The relationship between PLT/GGT and plaque stability in peripheral blood of patients with coronary heart disease and the evaluation value of PLT/GGT on plaque stability were analyzed.Results:The levels of C-reactive protein (CRP) and gamma-glutamyl transferase (GGT) in the vulnerable plaque group were higher than those in the stable plaque group: (8.07 ± 1.85) mg/L vs. (7.23 ± 1.57) mg/L, (72.39 ± 10.85) U/L vs. (67.13 ± 8.57) U/L, and PLT, PLT/GGT levels were lower than those in the stable plaque group: (180.76 ± 11.75) × 10 9/L vs. (187.36 ± 12.47) × 10 9/L, 2.55 ± 0.42 vs. 2.84 ± 0.41, the differences were statistically significant ( P<0.05). Point two column correlation found that the plaque stability recognized by VH-IVUS in patients with coronary heart disease was related to CRP, GGT, PLT, PLT/GGT ( P<0.05). Receiver operating characteristic curve analysis showed that the area under the curve (AUC) for assessing plaque stability using the peripheral blood PLT/GGT in patients with coronary heart disease was 0.71, which had certain evaluation value. Conclusions:The peripheral blood PLT/GGT in patients with coronary heart disease is closely related to the plaque stability recognized by VH-IVUS, and can be used as an effective indicator for evaluating plaque stability in patients.
