Prognostic utility of the pericoronary fat attenuation index in patients with takotsubo cardiomyopathy

Journal of Cardiovascular Computed Tomography, 2023
The etiology of takotsubo cardiomyopathy (TCM) remains poorly understood and no optimal management strategy has been established. Identification of features associated with poor outcomes may improve the prognosis of patients with TCM. We aimed to identify the predictors of poor prognosis in patients with TCM using coronary computed tomography ...

Stent-specific fat attenuation index is associated with target vessel revascularization after PCI

European Radiology, 2023
To explore the clinical relevance of stent-specific perivascular fat attenuation index (FAI) in patients with stent implantation.A total of 162 consecutive patients who underwent coronary computed tomography angiography (CCTA) following stent implantation were retrospectively included.

Deep Learning-based Post Hoc CT Denoising for the Coronary Perivascular Fat Attenuation Index

Academic Radiology, 2023
Coronary inflammation related to high-risk hemorrhagic plaques can be captured by the perivascular fat attenuation index (FAI) using coronary computed tomography angiography (CCTA). Since the FAI is susceptible to image noise, we believe deep learning (DL)-based post hoc noise reduction can improve diagnostic capability.

Abstract 15792: COVID-19 and Pericoronary Fat Attenuation Index; Is There a Link?

Circulation, 2023
Introduction: Pericoronary fat attenuation index (pFAI) is a marker of coronary inflammation, a key step in atherosclerotic plaque formation. COVID-19 infection has also been shown to be associated with significant systemic inflammation. The aim of this study is to assess the impact of active COVID-19 infection on pFAI.

Prediction value of pericoronary fat attenuation index for coronary in-stent restenosis

European Radiology
As a novel imaging marker, pericoronary fat attenuation index (FAI) reflects the local coronary inflammation which is one of the major mechanisms for in-stent restenosis (ISR). We aimed to validate the ability of pericoronary FAI to predict ISR in patients undergoing percutaneous coronary intervention (PCI).Patients who underwent coronary CT ...

Coronary computed tomography angiography-derived fat attenuation index predict future percutaneous coronary intervention

British Journal of Radiology
Abstract Objectives This study aims to investigate the differences in plaque characteristics and fat attenuation index (FAI) between in patients who received revascularization versus those who did not receive revascularization and examine whether the machine learning (ML)-based model constructed by ...

Lp(a) and vascular inflammation: data from perivascular fat attenuation index measurements

European Journal of Preventive Cardiology
Abstract Introduction/Purpose Elevated lipoprotein(a) [Lp(a)] values consist an independent cardiovascular risk factor. So far, there are no approved pharmaceutical treatments available to reduce Lp(a) in clinical practice, while antisense oligonucleotides which can induce a drastic reduction of Lp(a)
