BACKGROUND Abdominal aortic aneurysm (AAA) is a multifactorial vascular disease associated with high morbidity and mortality. Currently, surgical intervention is the only treatment option and there is no drug therapy available for AAA. Hence, surveillance of AAA until indication for surgery may impact patient quality of life (QoL). There is a paucity of high-quality observational data on health status and QoL, particularly among AAA patients participating in randomized controlled trials. The objective of this study was to compare QoL scores of AAA patients on surveillance to those of AAA patients enrolled in the MetAAA trial. MATERIAL AND METHODS Overall, 54 MetAAA trial patients and 23 AAA patients under regular surveillance for small AAA (of a longitudinal monitoring study) were asked to complete three established and validated (in total 561 longitudinally collected) QoL questionnaires: 1) the 36-Item Short Form Health Survey (SF-36), 2) the Aneurysm Symptom Rating Questionnaire (ASRQ), and 3) the Aneurysm-Dependent Quality of Life questionnaire (ADQoL). RESULTS A superior health status and QoL was found in AAA patients participating in the MetAAA trial compared to AAA patients under regular surveillance. In detail, MetAAA trial patients showed superior general health perception (P=0.012), higher energy level (P=0.036) as well as enhanced emotional well-being (P=0.044) and fewer limitations due to general malaise (P=0.021), which was subsequently reflected in an overall superior current QoL score (P=0.039) compared to AAA patients under regular surveillance. CONCLUSION AAA patients enrolled in the MetAAA trial showed superior health status and QoL compared to AAA patients under regular surveillance.
