Key result
Scoping review evaluates the diagnostic role of CPET-SE in adult outpatients with cardiopulmonary dysfunction.
Why the study?
The application of simultaneous cardiopulmonary exercise test with stress echocardiography has been broad and unstructured, and its effect on patient outcomes remains unclear.
This protocol outlines a scoping review to map the evidence and applications of simultaneous cardiopulmonary exercise testing and stress echocardiography for evaluating outpatient cardiopulmonary dysfunction.

Scoping review protocol will map CPET-SE utility; extends evidence synthesis for combined cardiopulmonary diagnostics in outpatients.
BACKGROUND: Cardiopulmonary dysfunction is a complex process with a broad range of etiologies. Investigations performed either at rest or those that only assess the function of a single organ (heart or lungs) are often insufficient. A simultaneous cardiopulmonary exercise test with stress echocardiography is a new approach to assessing cardiopulmonary dysfunction as it provides anatomical and functional imaging simultaneously while under increasing stress. To date, the application of cardiopulmonary exercise test-stress echocardiography (CPET-SE) has been broad and without structure, and its effect on patient outcomes is unclear. OBJECTIVE: The objective of this scoping review is to explore and analyze the evidence regarding the role of simultaneous CPET-SE in investigating cardiopulmonary dysfunction in outpatients. It will include any published study in which adult (older than or equal to 18 years of age) patients have completed a CPET-SE for the investigation of cardiopulmonary dysfunction. METHODS: This review will follow the Arksey and O'Malley framework, supported by the Joanna Briggs Institute methodology for scoping reviews. It will use the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) checklist. Data sources will include MEDLINE, Scopus, Embase, and Cochrane (including reviews, trials, and protocols) electronic databases, with no date range defined. The search will be limited to the English language with no restrictions regarding pathology. Secondary references of the included sources will also be assessed by a hand search for suitability. A 2-person title-abstract screen and data charting process will be used. Independent experts will be used for consultation including an academic librarian and clinicians. The Covidence software will be used for article screening. RESULTS: This scoping review will provide a unified and detailed description of the applications of CPET-SE in investigating cardiopulmonary dysfunction. This will provide a platform for future research harnessing this investigatory method. The results will be presented in both tabular and graphical formats to ensure clarity. The results of this scoping review will be submitted to a relevant peer-reviewed academic journal for publication. CONCLUSIONS: The CPET-SE is a powerful tool for investigating cardiopulmonary dysfunction but remains in its infancy with a patchwork approach to indications, data reporting, and interpretation. This scoping review will unify the literature and provide a platform for future researchers and the development of a comprehensive application guideline.

Gerhardy et al. (2024) studied Cardiopulmonary dysfunction. Simultaneous cardiopulmonary exercise testing and stress echocardiography (CPET-SE) was evaluated. Simultaneous cardiopulmonary exercise testing and stress echocardiography (CPET-SE) will be evaluated in a scoping review to determine its role and diagnostic benefit in investigating adult outpatients with cardiopulmonary dysfunction.
