Abstract: | Research examining the clinical value of exercise testing and training in patients with chronic lung disease and pulmonary arterial hypertension (PAH) is less robust compared with cardiac populations but nevertheless highly supportive. Functional limitations are common in these patients, and exercise testing provides important information pertaining to the degree of this limitation, disease severity, and prognosis. Moreover, exercise testing, particularly in conjunction with ventilatory expired gas analysis, serves as a valuable diagnostic tool when the mechanism of the functional limitation and abnormal exertional symptoms is uncertain. Most work with respect to the benefits of exercise training has been performed in chronic obstructive lung disease cohorts and is used to support pulmonary rehabilitation. Emerging data indicate that exercise training is likewise beneficial in patients with interstitial lung disease and PAH. This review summarizes the evidence supporting the value of exercise testing and training and provides recommendations for clinical practice. |
