Introduction: Pericoronary fat thickness (PFT) is a well-established marker crucial for evaluating the extent and severity of coronary artery disease (CAD). While its role in CAD is widely acknowledged, a considerable gap exists in understanding the prognostic implications of PFT after percutaneous coronary intervention (PCI), specifically for coronary chronic total occlusions (CTO). Aim: This study investigated the relationship between PFT and prognostic outcomes in patients undergoing PCI for CTO. Material and methods: A retrospective study analyzed data from 415 patients who had undergone coronary computed tomography angiography (CCTA) and coronary angiography (CAG). PFT measurements were taken, and patients were categorized into normal, PCI (non-CTO), and CTO-PCI groups. Prognostic implications within the CTO-PCI group were evaluated based on survival status. Results: PFT measurements varied significantly among groups. The CTO-PCI group had a 13.9% mortality rate over a median follow-up of 16.6 ±10.3 months. Higher average PFT values were found in the non-survival group (p = 0.013). ROC curve analysis identified an average PFT cut-off value of 13.6 mm (AUC = 0.682, p = 0.011). Cox regression analysis linked mortality with LVEF (HR = 0.938, p = 0.001), albumin (HR = 0.189, p = 0.006), and average PFT (HR = 1.252, p = 0.040). Elevated average PFT was associated with higher mortality (p = 0.001). Conclusions: PFT is a significant inflammatory marker and a promising prognostic indicator following PCI for CTO. Integrating PFT into risk prediction models may enhance prognostic accuracy and aid in timely clinical interventions. [ABSTRACT FROM AUTHOR]

Background: Chronic total occlusions (CTOs) of coronary arteries present a significant challenge in cardiology, with long-term outcomes following percutaneous coronary intervention (PCI) for CTOs remaining variable and unpredictable. The Naples prognostic score (NPS), which incorporates markers of nutritional status and systemic inflammation, has shown potential in predicting outcomes in various cardiovascular settings. This study evaluates the NPS as a predictor of long-term outcomes after PCI for CTOs., Methods: A retrospective analysis was conducted on 287 patients who underwent coronary angiography. Patients were categorized into non-CTO-PCI and CTO-PCI groups. Patients were further stratified based on survival status. Cox regression and Kaplan-Meier survival analyses were used to evaluate the association between NPS and long-term outcomes., Results: The mean age of the study population was 63.5 ± 10.6 years, with 28.6% being female. The NPS was significantly higher in the CTO-PCI group compared to the non-CTO-PCI group ( P = 0.004) and was also elevated in the non-survival group ( P = 0.004). Multivariable Cox regression analysis identified NPS as an independent predictor of mortality ( P = 0.015). Kaplan-Meier analysis demonstrated significantly higher mortality in patients with an elevated NPS ( P = 0.009)., Conclusion: The NPS is a valuable independent predictor of long-term mortality in patients undergoing CTO-PCI. Incorporating NPS into existing risk stratification models could improve predictive accuracy and guide individualized patient management. Further prospective studies are warranted to validate these findings and explore interventions targeting inflammation and nutrition in this high-risk population., (Copyright © 2025 Wolters Kluwer Health, Inc.
