COPD is a heterogeneous disease with a wide range of clinical phenotypes and breath-functional dysfunctions. Cardiopulmonary exercise testing (CPET) allows describing all component parts of breathing and determining exercise capacity and the mechanisms of exercise limitation. From these aspects 64 COPD patient stages II, III and IV according to the conventional GOLD classification were examined by means of CPET to evaluate whether CPET can provide a better functional characterization of COPD…

Value of Cardiopulmonary Exercise Testing in Prognostic Assessment of Patients with Interstitial Lung Diseases
TLDR
VO2peak (mL/kg/min or %pred.) was identified as a significant prognostic parameter in patients with ILD and showed an even higher prognostic ability in all statistical models.
Cardiovascular Comorbidities in Chronic Obstructive Pulmonary Disease (COPD)—Current Considerations for Clinical Practice
TLDR
Future diagnostic and therapeutic strategies should therefore be guided by an integrative perspective as well as a refined phenotyping of disease entities.

Cardiopulmonary exercise testing in evaluation of patients of chronic obstructive pulmonary disease.
TLDR
Cardiopulmonary exercise testing is useful to determine the causes of exercise limitation and to assess the maximal exercise capacity of patients with COPD.
Cardiopulmonary Exercise Testing in the Functional and Prognostic Evaluation of Patients with Pulmonary Diseases
TLDR
The aim of this review is to focus on the main respiratory diseases for which exercise tolerance is indicated; for example, chronic obstructive pulmonary disease, interstitial lung disease, primary pulmonary hypertension and cystic fibrosis.
Cardiopulmonary Exercise Test Characteristics in Patients with Chronic Obstructive Pulmonary Disease and Associated Pulmonary Hypertension
TLDR
Although CPET characteristics showed a large overlap in both groups, the existence of PH in COPD is associated with a significantly reduced ventilatory efficiency during CPET, and a low SpO2 at rest and a further decrease during exercise similarly suggest the presence of PHIn COPD.
Prognostic predictors for survival in patients with COPD using cardiopulmonary exercise testing
TLDR
CPET is a useful technique to accurately assess the relationship between the functional impairments and the prognosis of patients with COPD, and the Pao2‐slope was most closely associated with the survival time.
Mechanisms of exercise intolerance in Global Initiative for Chronic Obstructive Lung Disease grade 1 COPD
TLDR
Increased respiratory effort and work of breathing, and a wider dissociation between diaphragmatic activation and pressure-generating capacity were found at standardised work rates in subjects with mild COPD compared with controls, Despite these mechanical and neuromuscular abnormalities, significant dyspnoea was only experienced at higher work rates.
Predictive properties of different multidimensional staging systems in patients with chronic obstructive pulmonary disease
TLDR
The multidimensional staging systems using the mBODE, ADO, and mDOSE indices were significant predictors of mortality in COPD patients, although exercise capacity had a more significant relationship with mortality than those indices.
The haemodynamic response to exercise in chronic obstructive pulmonary disease: assessment by impedance cardiography.
TLDR
In chronic obstructive pulmonary disease an aberrant haemodynamic response to exercise was found, especially in patients with severe airflow obstruction, and this aberrant response is related to the degree of airflow obstruction and may limit exercise performance in Patients with severe chronic obstructives pulmonary disease.
Assessing Exercise Limitation Using Cardiopulmonary Exercise Testing
TLDR
The cardiopulmonary exercise test (CPET) is an important physiological investigation that can aid clinicians in their evaluation of exercise intolerance and dyspnea and when combined with other clinical/investigation studies, can provide the clinician with an objective method.
Exercise capacity deterioration in patients with COPD: longitudinal evaluation over 5 years.
TLDR
Clear evidence of measurable and progressive deterioration in exercise capacity in COPD patients is demonstrated, which was no less rapid than the decline in airflow limitation.
Sildenafil treatment in COPD does not affect stroke volume or exercise capacity
TLDR
A reduced stroke volume was found at rest and during exercise and neither stroke volume nor exercise capacity were improved by 3 months of sildenafil therapy.
