Abstract

<jats:title>Abstract</jats:title><jats:p>Cardiopulmonary exercise testing (CPET) allows objective assessment of a patient’s global response to maximal incremental exercise. CPET has been proposed to have a role in investigating post-COVID syndrome. However, CPET is resource intensive, and essential for restoration of other clinical services (e.g. cancer surgery). The aim of this study was to explore utility of CPET in assessing functional status of COVID-19 survivors with persistent dyspnoea. Of the 600 patients reviewed in a post-COVID-19 assessment clinic between May 2020 and April 2021, 12 (male/female: 8/4; age: 4±15.2 years; BMI: 32.8±5.9 kg/m2; non-smokers/ smokers: 8/4) were referred for CPET due to persistent breathlessness out-keeping with disease severity. Of these patients, 10 patients demonstrated reduced peak VO2, whilst five had an exercise limitation attributed to physical deconditioning. Two patients had mainly a cardiac limitation to exercise, with a further three patients demonstrating breathing pattern disorder, pulmonary vascular disease and lung disease.The findings of this single-centre study suggest that intensive CPET testing may not add substantial additional clinical information to aid patient investigation/management in the context of post-COVID. Such resource intensive procedures may be better utilised in selected patients and in the restoration of NHS services following the COVID-19 pandemic.</jats:p>
