Predictive Value of the Systemic Immune-Inflammation Index for Cardiovascular Events in Patients With Chronic Total Coronary Occlusion
By Yuhao Zhao, Ping Wang, Shun Zhao and 4 others.
Abstract
Background
This large-scale cohort study aimed to evaluate the prognostic role of the systemic immune-inflammation index (SII) in patients with chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI).
Methods
A total of 3107 patients with CTO lesions who underwent PCI were enrolled in this study. Clinical characteristics were collected, and post-discharge major adverse cardiovascular events (MACEs) were recorded during follow-up, including all-cause mortality, non-fatal myocardial infarction, unplanned revascularization, and heart failure-related readmission. Patients were stratified into three groups according to SII tertiles: the low SII group (SII ≤447.66, n = 1036), the intermediate SII group (447.66 < SII < 679.89, n = 1039), and the high SII group (SII ≥679.89, n = 1032).
