Abstract
Background: Carotid artery stenting (CAS) has been widely used to remodel the vascular structure and restore the blood flow for preventing ischemic stroke. However, in-stent restenosis (ISR) after CAS is extremely associated with an increased risk of ischemic stroke recurrence.
Objective: The aim of this study was to explore potential predict biomarkers for ISR after CAS.
Methods: In this study, data from 221 patients with CAS, which was divided into no-ISR group and ISR group, and 145 healthy controls were retrospectively analyzed. The ratios of neutrophil, lymphocyte, monocyte, platelet, glucose (Glu), and triglyceride (TG) to lymphocyte, HDL, and LDL were analyzed, respectively. In addition, the ratios of SII, SIRI, and AISI were analyzed as the following formulas: SII = platelet × neutrophil-to-lymphocyte ratio, SIRI = monocyte × neutrophil-to-lymphocyte ratio, and AISI = neutrophil × platelet × monocyte-to-lymphocyte ratio. ROC curve analysis was performed to analyze the predict roles of PLR and platelet/LDL for ISR.
Results: The ratios of NLR, PLR, Glu/lymphocyte, TG/lymphocyte, NHR, PHR, Glu/HDL, TG/HDL, neutrophil/LDL, platelet/LDL, Glu/LDL, TG/LDL, and SII increased in patients with CAS, indicating the predict roles of these values in carotid artery stenosis. Most importantly, increased ratios of PLR and platelet/LDL before the first operation of CAS, but not the second operation, were found in ISR patients after CAS as compared with no-ISR group. ROC analysis showed a more effective role of PLR for predicting ISR. While PLR showed high specificity (96.95%), its modest sensitivity (35.29%) suggests the need for complementary biomarkers in clinical practice.
Conclusion: These results indicate that ratios of PLR and platelet/LDL before the first CAS operation can act as the predict biomarkers of ISR.
期刊介绍：
An international, peer-reviewed journal of therapeutics and risk management, focusing on concise rapid reporting of clinical studies on the processes involved in the maintenance of vascular health; the monitoring, prevention, and treatment of vascular disease and its sequelae; and the involvement of metabolic disorders, particularly diabetes. In addition, the journal will also seek to define drug usage in terms of ultimate uptake and acceptance by the patient and healthcare professional.
