Inclusion/Exclusion Criteria
Of the 620 patients identified, we included 465 patients age ≥18 years
old with ascending aortic size ≥4 cm on chest CT, including 4 patients
with aortic dissection (2 acute, 2 chronic) on index scan. 18 patients
were excluded due to ADI information being unavailable. 41 patients were
excluded for residential address outside the state of Connecticut, due
to concern for incomplete follow-up information in our institutional
electronic medical record (EMR). 13 patients with only Post Office
(P.O.) Box address were excluded. We excluded 10 patients who were lost
to follow-up, defined as no listed encounters in the EMR within 4 years
after the index CT scan, and 73 patients with mortality occurring less
than 6 months after the index CT scan.
