Background: Prospective data on the clinical course of the ascending thoracic aorta are lacking.
Objectives: This study sought to estimate growth rates of the ascending aorta and to evaluate occurrences of adverse aortic events (AAEs)-that is, thoracic aortic ruptures, type A aortic dissections, and thoracic aortic-related deaths.
Methods: In this prospective cohort study from the population-based, multicenter, randomized DANCAVAS (Danish Cardiovascular Screening trials) I and II, participants underwent cardiovascular risk assessments including electrocardiogram-gated, noncontrast computed tomography (CT) scans.
Article Synopsis
- Coronary computed tomography angiography (CCTA) is useful for analyzing coronary atherosclerotic plaques, but previous studies on the consistency of plaque volume measurements between scans are limited.
- In a study involving 101 patients, CCTA scans were performed twice with a one-hour interval using identical protocols, and plaque volumes were assessed using semi-automated software.
- Results showed high correlation for total, non-calcified, and calcified plaques, but lower for low-density non-calcified plaques, with reproducibility influenced by image quality, reconstruction settings, and lesion location, particularly in left anterior descending (LAD) arteries.
Coronary CT angiography (CTA) derived fractional flow reserve (FFR) is recommended for physiological assessment in intermediate coronary stenosis for guiding referral to invasive coronary angiography (ICA). In this study, we report real-world data on the feasibility of implementing a CTA/FFR test algorithm as a gatekeeper to ICA at referral hospitals. Retrospective all-comer study of patients with new onset stable symptoms and suspected coronary stenosis (30-89%) by CTA.

This study investigated the correlation between local instantaneous dose rate and radiation-induced oxygen pressure reduction during proton pencil beam scanning (PBS) irradiations of a sample and quantified the oxygen consumption g-value.

Background: Some autoimmune diseases carry elevated risk for atherosclerotic cardiovascular disease (ASCVD), yet the underlying mechanism and the influence of traditional risk factors remain unclear.
Objectives: This study sought to determine whether autoimmune diseases independently correlate with coronary atherosclerosis and ASCVD risk and whether traditional cardiovascular risk factors modulate the risk.
Methods: The study included 85,512 patients from the Western Denmark Heart Registry undergoing coronary computed tomography angiography.
