Abstract 13937: Socioeconomic Status in Pediatric Patients With Anomalous Aortic Origins of Coronary Arteries: An Individual- and Zip Code-Level Analysis

Abstract

Introduction: Anomalous aortic origin of a coronary artery (AAOCA) is the second leading cause of sudden cardiac death in the young. Limited data is available on potential disparities on access to care and whether socioeconomic status is associated with AAOCA. Hypothesis: AAOCA occurrence, severity, and treatment relate to socioeconomic status and may unfold inequities to care. Methods: Single-center retrospective study of 553 pediatric patients with AAOCA residing in Texas. Zip code socioeconomic characteristics were extracted from American Community Survey 2021 5-year estimates. All Texas zip codes were ordered into quartiles by characteristic. Age at diagnosis, signs of ischemia, and surgery status were compared by race and zip code parameters. Mann-Whitney U test was for non-parametric variables and χ 2 test, Fisher’s test, or one-way ANOVA for categorical variables. Results: Table 1 depicts patients’ demographics. AAOCA patients tended to reside in zip codes at the 4 th quartile of income (39%, p=<0.001), education (29%, p=0.003), and employment (42%, p=<0.001) (Table 2). There was no difference in age at diagnosis, signs of ischemia, or occurrence of coronary surgery by individual race or zip code socioeconomic parameters. Conclusions: AAOCA pediatric patients tend to live in zip codes with higher socioeconomic status (SES). These differences may reflect disparities in access to diagnosis and care. Further studies are needed to determine the burden of AAOCA in low SES populations.
