In vivo Predictors of Focal Type In-Stent Restenosis: A Clinical, Angiographical, and Optical Coherence Tomography Study.

ABSTRACT:

Introduction

Few studies have evaluated different patterns of in-stent restenosis by optical coherence tomography (OCT). This study aimed to identify in vivo predictors for focal restenosis in patients with in-stent restenosis (ISR).

Methods

The study recruited patients with ISR who underwent OCT examination in the Cardiology Department of the Affiliated Hospital of Zunyi Medical University from October 2018 to December 2022. Based on the angiographic classification of ISR lesions, the patients were divided into two groups: the focal group (n = 58) and the non-focal group (n = 158).

Results

The white blood cell count was higher in the non-focal group than those in focal type (7.8 ± 3.0 vs. 6.6 ± 2.1, p = 0.007). The prevalence of lipid-rich plaque was higher in patien
