BackgroundSurgical intervention for thoracic aortic aneurysms is high risk. Understanding changes in health-related quality of life before and after endovascular stent grafting and open surgical repair can aid treatment decision-making.MethodsThe Effective Treatments for Thoracic Aortic Aneurysms ('ETTAA') study (ISRCTN04044627) was a longitudinal, observational study. Adults with new/existing arch or descending thoracic aortic aneurysms greater than or equal to 4 cm in diameter were followed from 2014 to 2022. Five domains of health-related quality of life (Mobility, Self-Care, Usual Activities, Pain/Discomfort, and Anxiety/Depression) were recorded using the EuroQoL, five dimensions, five levels ('EQ-5D-5L') questionnaire and analysed using a range of longitudinal mixed models.ResultsOf 886 thoracic aortic aneurysm participants, 824 completed at least 2 questionnaires. Patients had slightly worse health-related quality of life than age-matched norms. Without surgery, deterioration occurred over time in Mobility (0.072/year (95% c.i. 0.042 to 0.101), P < 0.001) and Self-Care (0.039/year (95% c.i. 0.018 to 0.061), P < 0.001) in both sexes and Pain/Discomfort in women (0.069/year (95% c.i. 0.020 to 0.118), P = 0.005). For 6 weeks after endovascular stent grafting, there was a significant impairment in Self-Care (0.214 (95% c.i. 0.112 to 0.316), P < 0.001) and (for women only) in Usual Activities (0.625 (95% c.i. 0.338 to 0.911), P < 0.001), which then returned to pre-endovascular stent grafting levels. Six weeks after open surgical repair, the impairment in health-related quality of life was greater (Mobility 0.492 (95% c.i. 0.314 to 0.669), Self-Care 0.474 (95% c.i. 0.364 to 0.583), Usual Activities 1.469 (95% c.i. 1.042 to 1.896), and Pain/Discomfort 0.561 (95% c.i. 0.363 to 0.760), all P < 0.001) and took longer to return to pre-open surgical repair levels, partly due to increased complications and longer hospitalization. Anxiety/Depression decreased after open surgical repair (-0.214 (95% c.i. -0.326 to -0.101), P < 0.001). Age, sex, frailty, smoking, New York Heart Association class, and chronic obstructive pulmonary disease were significantly associated with health-related quality of life.ConclusionWithout intervention, health-related quality of life declines as age increases. Changes in health-related quality of life should contribute to surgical treatment decision-making.© The Author(s) 2024. Published by Oxford University Press on behalf of BJS Foundation Ltd.
