Brief Title
Biomarker Profiling in Abdominal Aortic Aneurysm Patients
Official Title
Study of Biomarker Profiling to Unravel the Intertwined Pathophysiology of Coronary Artery Disease and Abdominal Aortic Aneurysm
Brief Summary
The BIOMArCS-AAA study aims to investigate the associations of (temporal patterns of) blood biomarkers with aneurysm growth in patients with abdominal aortic aneurysm (AAA), with particular attention to biomarkers that have demonstrated prognostic value for adverse disease outcomes in coronary artery disease and biomarkers for the main genetic pathways associated with AAA.
Detailed Description
BIOMArCS-AAA is an observational, multicenter study. Patients with an abdominal aortic aneurysm (AAA) will be recruited through the vascular surgery outpatient clinic of Erasmus MC and Maasstad Ziekenhuis, the Netherlands. The prospective, longitudinal part of the study will include an arm with 120 AAA watchful waiting patients and an arm with 120 AAA patients undergoing endovascular aneurysm repair (EVAR), both with a 24-month follow-up period. Clinical data collection, and blood sampling will be conducted at baseline, at 1 month after EVAR and at 6, 12, 18 and 24 months for all patients. CT will be conducted at baseline and 12 and 24 months, plus at 1 month in the EVAR patients. Quality of life and depression questionnaires will be performed at baseline, at 12 and 24 months of follow-up in all patients, and at 1 month only in EVAR patients. Additionally, a cross-sectional study will be performed in 200 patients treated for AAA with EVAR in the past years. In these patients, clinical data collection, blood sampling, ultrasound and CT will be performed at their next regular outpatient clinic visit.
