Brief Review: Racial Disparities in the Presentation and Outcomes of Patients with Thoracic Aortic Aneurysms.

(1)

Background

Thoracic aortic aneurysms (TAAs) pose critical health risks and are often asymptomatic until a rupture or dissection occurs. Guidelines recommend surgical repair based on specific aortic diameters and risk factors, emphasizing the importance of early detection and intervention. Despite established clinical risk factors for the early detection of TAAs, the influence of racial disparities on TAAs remains underexplored. This study aims to provide a comprehensive summary of existing research on racial disparities in the presentation and outcomes of TAAs. (2)

Methods

This literature review was conducted using a systematic search strategy to explore racial differences in the presentation and surgical outcomes of patients with TAAs. (3)

Results

The findings demonstrated that black patients were younger at presentation and had a higher incidence of ruptured TAAs than non-black patients. Furthermore, compared to non-black patients, black patients had higher rates of cardiac arrhythmia and COPD, as well as comorbidities such as diabetes, hypertension, and renal insufficiency. For black patients undergoing open surgery, the surgical results showed improved 5-year survival rates after repair but higher perioperative mortality rates. All-cause or in-hospital mortality did not significantly differ between the racial groups, according to four studies. (4) Discussion: This review highlights significant racial disparities in TAA presentation and outcomes, underscoring the need for personalized risk stratification models. Standardized racial and ethnic definitions are essential for consistent and reliable research. Future studies should focus on identifying the underlying mechanisms driving racial disparities and on refining risk assessment models to enhance diagnostic and therapeutic strategies, ultimately improving patient outcomes across diverse populations.
