INTRODUCTION: To ensure flight safety military aircrew undergo regular clinical and occupational assessment. Coronary artery @entity460 scoring (CACS) has been established as an imaging modality to noninvasively assess @entity453 ( @entity453 ). CT coronary angiography (CTCA) potentially offers a more accurate assessment of @entity453 , but has not been formally assessed in military aircrew. This retrospective cohort study is designed to compare the theoretical differences in downstream investigations and occupational outcomes in aircrew with suspected @entity453 comparing CTCA with existing CACS pathways. METHOD: A 2-yr retrospective cohort study of consecutive UK military @entity1 who underwent a CTCA and CACS was undertaken. @entity1 demographics, CTCA and CACS results, and initial and final occupational restrictions were analyzed comparing current UK, Canadian, and U.S. pathways. RESULTS: There were 44 @entity1 who underwent CACS and CTCA. The commonest indication for a CTCA was a positive exercise ECG. Increasing CACS, @entity850 severity, and @entity850 burden were associated with significantly greater likelihood of occupational restriction (P = < 0.01). Following CTCA, 26/44 (59%) @entity1 were found to have evidence of @entity453 , with 13/44 (30%) having at least a single vessel @entity850 >= 50%. All of these @entity1 had subsequent occupational restrictions. Two @entity1 with a @entity460 score <= 10 had at least 1 single vessel @entity850 >= 50%. DISCUSSION: A CTCA pathway is potentially a better discriminator of @entity453 burden in aircrew when compared with CACS and may reduce downstream testing, allowing a more efficacious approach to @entity453 assessment in military aircrew.Parsons I, Pavitt C, Chamley R, d'Arcy J, Nicol E.
