Vessel and sex differences in pericoronary adipose tissue attenuation obtained with coronary CT in individuals without coronary atherosclerosis [PDF]

, 2022
Pericoronary adipose tissue (PCAT) attenuation, derived from coronary computed tomography angiography (CCTA), is associated with coronary artery inflammation. Values for PCAT attenuation in men and women without atherosclerosis on CCTA are lacking.

Association of Glycemic Indices (Hyperglycemia, Glucose Variability, and Hypoglycemia) with Oxidative Stress and Diabetic Complications

Journal of Diabetes Research, Volume 2020, Issue 1, 2020., 2020
Oxidative stress (OS) is defined as a disturbance in the prooxidant‐antioxidant balance of the cell, in favor of the former, which results in the antioxidant capacity of the cell to be overpowered. Excess reactive oxygen species (ROS) production is very harmful to cell constituents, especially proteins, lipids, and DNA, thus causing damage to the cell.

Prognostic value of fat attenuation index of pericoronary adipose tissue surrounding left anterior descending artery on coronary computed tomography angiography [PDF]

European Heart Journal, 2020
Abstract Background Recent studies reported the association between elevated fat attenuation index (FAI) of pericoronary adipose tissue (PCAT) on coronary computed tomography angiography (CTA) and worse cardiac outcomes.

Cardiovascular computed tomography imaging for coronary artery disease risk: plaque, flow and fat [PDF]

, 2022
Cardiac imaging is central to the diagnosis and risk stratification of coronary artery disease, beyond symptoms and clinical risk factors, by providing objective evidence of myocardial ischaemia and characterisation of coronary artery plaque. CT coronary

Differences in the Fat Attenuation Index Ratio of Pericoronary Adipose Tissue And Aortic Root Epicardial Adipose Tissue in Various Plaques

Current Medical Imaging Formerly Current Medical Imaging Reviews, 2023
Background:: The fat attenuation index (FAI) of pericoronary adipose tissue is associated with coronary inflammatory reactions. Objective:: volume (AO-EATV) using computed tomography (CT) in various plaques. Method:: In total, 645 coronary artery CT angiogram images from 215 patients were collected.

Impact of COVID-19 Infection on Regional Periocoronary Inflammation: An Angio-CT Study of Epicardial Fat Attenuation

Romanian Journal of Cardiology, 2023
It is currently well-known that inflammation plays an essential role in all phases of atherosclerosis. Recent CT studies showed that atherosclerotic plaques found in the right coronary arteries (RCA) display a greater number of features that increase ...

Diagnostic potential of pericoronary adipose tissue mean attenuation for coronary atherosclerotic heart disease: a comparative analysis with the fat attenuation index. [PDF]

Quant Imaging Med Surg
The fat attenuation index (FAI), a threshold-based method for assessing pericoronary adipose tissue (PCAT) density, provides strong evidence for patient-specific coronary inflammation assessment. However, the reliance on fat thresholds may result in the omission of some critical information. Thus, this study aimed to explore the diagnostic potential of
