Brief Report: Lower Socioeconomic Status Associates With Greater Systemic and Arterial Inflammation in HIV.

Objectives: In the general population, the lower socioeconomic status (SES) associates with greater systemic and arterial inflammation and a greater risk of cardiovascular disease. Because arterial inflammation is heightened in individuals living with HIV, we tested the hypothesis that SES associates with arterial inflammation in this population.

Settings: Prospective cohort study.

Relationship between chronic stress-related neural activity, physiological dysregulation and coronary artery disease in psoriasis: Findings from a longitudinal observational cohort study.

Background And Aims: Amygdalar 18F-fluorodeoxyglucose (FDG) uptake represents chronic stress-related neural activity and associates with coronary artery disease by coronary computed tomography angiography (CCTA). Allostatic load score is a multidimensional measure related to chronic physiological stress which incorporates cardiovascular, metabolic and inflammatory indices. To better understand the relationship between chronic stress-related neural activity, physiological dysregulation and coronary artery disease, we studied the association between amygdalar FDG uptake, allostatic load score and subclinical non-calcified coronary artery burden (NCB) in psoriasis.

Greater aortic inflammation and calcification in abdominal aortic aneurysmal disease than atherosclerosis: a prospective matched cohort study.

Objective: Using combined positron emission tomography and CT (PET-CT), we measured aortic inflammation and calcification in patients with abdominal aortic aneurysms (AAA), and compared them with matched controls with atherosclerosis.

Methods: We prospectively recruited 63 patients (mean age 76.1±6.

Imaging atherosclerotic plaque inflammation by fluorodeoxyglucose with positron emission tomography: ready for prime time?

Inflammation is a determinant of atherosclerotic plaque rupture, the event leading to most myocardial infarctions and strokes. Although conventional imaging techniques identify the site and severity of luminal stenosis, the inflammatory status of the plaque is not addressed. Positron emission tomography imaging of atherosclerosis using the metabolic marker fluorodeoxyglucose allows quantification of arterial inflammation across multiple vessels.
