Background: Risk assessment in the extensive calcified plaque phenotype has been limited by small sample size.
Objective: We studied all-cause mortality rates among asymptomatic patients with markedly elevated Agatston scores > 1000.
Methods: We studied a clinical cohort of 44,052 asymptomatic patients referred for coronary calcium scans.
Objectives: Because fluorodeoxyglucose positron emission tomography (FDG-PET) imaging provides a noninvasive index of inflammation, we sought to assess whether FDG uptake in the aortic valve (AV) is increased in aortic stenosis (AS).
Background: AS is associated with valvular inflammation.
Methods: FDG-PET/computed tomography data were retrospectively evaluated in 84 patients (age 73 ± 9 years, 45% female), 42 patients with AS, and 42 age-matched controls.
Objectives: This study aimed to test the hypothesis that metabolic activity within periodontal tissue (a possible surrogate for periodontal inflammation) predicts inflammation in a remote atherosclerotic vessel, utilizing (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) imaging.
Background: Several lines of evidence establish periodontal disease as an important risk factor for atherosclerosis. FDG-PET imaging is an established method for measuring metabolic activity in human tissues and blood vessels.
Objective: To assess the availability, practices and knowledge of radiation safety measures among invasive cardiologists in a tertiary care hospital.
Method: A cross sectional survey of invasive cardiologists working in academic institutions was conducted using a questionnaire.
Results: A total of 28 cardiologists completed the questionnaire with a mean working experience of 10.
