Key result
CPET stratifies risk and tracks exercise capacity improvements for COPD patients undergoing pulmonary rehabilitation.
Why the study?
Cardiopulmonary exercise testing (CPET) is not regularly performed as a screening test prior to pulmonary rehabilitation (PR) in COPD patients, nor often used to assess improvement after PR.
This review describes the role of cardiopulmonary exercise testing (CPET) in risk stratification, safety assessment, and evaluating outcomes of pulmonary rehabilitation in patients with COPD.
CPET may aid risk stratification before PR in COPD; leaves open whether routine use improves safety or outcomes over standard assessments.
Chronic obstructive pulmonary disease (COPD) is a common multisystem inflammatory disease with ramifications involving essentially all organ systems. Pulmonary rehabilitation is a comprehensive program designed to prevent and mitigate these disparate systemic effects and improve patient quality of life, functional status, and social functioning. Although initial patient assessment is a prominent component of any pulmonary rehabilitation (PR) program, cardiopulmonary exercise testing (CPET) is not regularly performed as a screening physiologic test prior to PR in COPD patients. Further, CPET is not often used to assess or document the improvement in exercise capacity related to completion of PR. In this review we will describe the classic physiologic abnormalities related to COPD on CPET parameters, the role of CPET in Risk Stratification/Safety prior to PR, the physiologic changes that occur in CPET parameters with PR, and the literature regarding the use of CPET to assess PR results. Finally, we will compare CPET to 6MW in COPD PR, the common minimal clinically important difference (MCID) is associated with CPET, and the potential future roles of CPET in PR and Research.

Stringer et al. (2018) conducted a review in Chronic Obstructive Pulmonary Disease (COPD). Cardiopulmonary Exercise Testing (CPET) vs. 6-minute walk test (6MW) was evaluated. Cardiopulmonary exercise testing (CPET) serves as a physiologic assessment tool for risk stratification and evaluating exercise capacity improvements in COPD patients undergoing pulmonary rehabilitation.
