Prevalence of thoracic aortic aneurysm in patients referred for no/low-charge coronary artery calcium scoring: Insights from the CLARIFY registry.

ABSTRACT:

Objective

Low-dose cardiac-gated chest CTs allow for simultaneous evaluation of coronary artery calcification and aortic size. We sought to evaluate the prevalence of thoracic aortic dilation (TAD) and thoracic aortic aneurysm (TAA) in a large cohort of patients undergoing coronary artery calcium (CAC) screening.

Methods

We reviewed all patients from a large, prospective no-charge CAC screening program (CLARIFY, Clinicaltrials.gov NCT04075162) for whom measurements of the ascending aorta were available. TAD was defined as an ascending aortic diameter ≥4.0cm, while TAA was defined as ascending aortic diameter ≥ 4.5cm. We explored associations between patient characteristics, CAC, and the prevalence of TAD/TAA.

Results

A total of 36,356 patients enrolled in the CLARIFY
