The investigators will include 192 patients with an AAA who will be scheduled for repair. Participants will be recruited from all collaborating hospitals (currently Radboudumc, Rijnstate, CWZ) after providing written informed consent. In this observational, prospective study, a total of 192 patients who are going to be treated for their AAA will be included. Baseline patient characteristics will be registered, including traditional risk factors and CV-history. In addition to regular care of measuring AAA diameter progression (in mm/year), we will perform the CAR-test (10-min) and non-invasive arterial stiffness measures (PWA and PWV) with the SphygmoCor device (10-min). Furthermore, the investigators will ask patients to complete a questionnaire about the quality of their life. A second questionnaire tries to clarify the disease experience of the patients. Both questionnaires will be asked to be completed at the start, 6-8 weeks after repair, after one year and after two years of repair. Subsequently, the investigators will record major adverse cardiovascular events (MACE) according to the International Classification of Disease-10. Registration of MACE will be performed using hospital-records and following international guidelines. Across a 2-year follow-up, by means of regular follow-up appointments, the investigators will examine the ability of the CAR parameter and arterial stiffness parameters to predict CV-events.
