Modified algorithm based on previously published guidelines (ACSM, 2010; American Thoracic Society, 2003; Laveneziana et al., 2021; Levett et al., 2018; Pelliccia et al., 2021; Pritchard et al., 2021; Radtke et al., 2019), highlighting a systematic approach to clinical stratification, precautions, optimization and corresponding risk mitigation during cardiopulmonary exercise testing (CPET) in patients with an abdominal aortic aneurysm (AAA). Note that CPET data should be interpreted by a specialist and functionally integrated with other clinical findings, including surgical/anaesthetic factors, AAA diameter/morphology and resting/exercise blood pressure responses, with the last of these monitored continuously (as highlighted). *Please refer to Table 1. Abbreviations: CAD, coronary artery disease; COPD, chronic obstructive pulmonary disease; EVAR, endovascular repair; ILD, interstitial lung disease; MDT, multidisciplinary team; PE, pulmonary embolus. Turndown refers to a patient deemed unsuitable for surgical repair of AAA.
