Article Abstract
Background: There is a significant relationship between calcification of the aortic arch (Arch) detected by chest X-ray examination and coronary artery disease (CAD), but the relationship between risk factors, CAD and aortic calcification detected during a mass screening program using a mobile helical computed tomography (CT) unit remains unknown.
Methods And Results: In total 2,623 subjects (1,347 men, and 1,276 women; mean age, 52.9+/-13.8) underwent an examination for lung cancer and tuberculosis using a mobile helical CT unit. The frequency of calcification was 19.6% in the Arch, 2.7% in the ascending aorta, and 10.1% in the descending aorta, values that were positively associated with age in both genders. Hypertension and smoking were significantly related to calcification of the thoracic aorta. There was a significant relationship between CAD and aortic calcification. The odds ratio of aortic calcification for patients with CAD increased as the number of calcified segments increased.
Conclusions: These results suggest that detection of calcification in the thoracic aorta during a mass chest screening using a mobile helical CT unit can be used to evaluate the risk of CAD.

The purpose of this article was to study the distribution of left ventricular hypertrophy (LVH) and cardiac valve calcification (CVC), relevant factors, and the relationship of LVH and CVC with survival in maintenance hemodialysis (MHD) patients. A total of 281 MHD patients were included in this retrospective and follow-up study. Echocardiography measurements were performed to evaluate the left ventricular structure and cardiac valve.

Background: Greater deposits of epicardial adipose tissue are associated with atrial fibrillation and coronary disease, but have not been studied in subsistence populations.
Methods: We performed CT imaging to measure coronary artery and thoracic aortic calcium (CAC, TAC), epicardial fat thickness (EFT), liver density, and left atrial (LA) anteroposterior diameter and, using a deep learning-enabled software program, epicardial and thoracic fat volume (EFV, TFV), in two remote Amerindian subsistence populations with minimal coronary artery calcification and virtually no atrial fibrillation. We compared 893 adult Tsimane (mean age 58.

Objective: Sex specific anatomical differences may contribute to observed disparities in outcomes and suitability for endovascular aneurysm repair (EVAR) between men and women with abdominal aortic aneurysms (AAAs). This study aimed to assess these differences using fully automated volume segmentation (FAVS) and explore implications for EVAR suitability.
Methods: This was a retrospective, multicentre cohort study of patients undergoing elective AAA repair between 2013 and 2023 in three UK tertiary centres.
