Imaging Follow-Up
313 (67.3%) and 374 (80.4%) patients received at least one
echocardiogram or chest CT within 12- and 24-months post-index scan,
respectively (Table 2 ). Only 124 (33.2%) of patients imaged
before 24 months were done so for thoracic aneurysm-related indications.
Less disadvantaged quartiles were more likely to receive imaging at 24
months compared to the most disadvantaged quartile (Q2: 88% vs Q4:
71%, p<0.001). Conversely, active malignancy (4.12 [2.37,
7.57], p<0.001) and COPD (2.47 [1.21, 5.75], p=0.011)
were associated with increased odds of imaging (Table 3 ). The
trend for more disadvantaged quartiles being less likely to receive
follow-up imaging persisted even after adjusting for family history of
TAA, active malignancy, prior smoking history, congestive heart failure,
and COPD on multivariate analysis (p=0.006 for Q4), Table 3 .
