|
Measurement of Oxygen pulse during cardiopulmonary exercise testing
Time Frame: Baseline
|
Baseline
|
|
|
Presence of cardiovascular comorbidities
Time Frame: Baseline
|
For the cardiopulmonary characterization clinical characteristics, lung function, blood gases, laboratory investigation, ECG and echocardiography were used in addition to cardiopulmonary exercise testing.
|
Baseline
|
|
measurement of dyspnoea quantified by the COPD assessment test as well as the modified Medical Research Council Scale
Time Frame: Baseline
|
For the assessment of the symptoms of the study group and its relation to exercise capacity dyspnoea is assessed by accepted questionnaires typically used for COPD patients at baseline
|
Baseline
|
|
Measurement of FEV1
Time Frame: Baseline
|
Baseline
|
|
|
Measurement the capillary pO2 in mmHg and capillary pCO2 at baseline
Time Frame: Baseline
|
The blood gases pO2 and pCO2 are taken from the hyperaemic ear lobe to characterize the gas exchange during cardiopulmonary exercise which is a routine procedure
|
Baseline
|
|
N-terminal pro brain natriuretic peptid (NTproBNP) in ng/L from peripheral venous blood at baseline
Time Frame: Baseline
|
NTproBNP is analysed from peripheral venous blood to characterize potential heart failure and its relation to exercise capacity of the study subjects
|
Baseline
|
|
Measurement of Maximum wattage during cardiopulmonary exercise testing
Time Frame: Baseline
|
Baseline
|
|
|
Measurement of Breathing reserve during cardiopulmonary exercise testing
Time Frame: Baseline
|
BThe breathing reserve in % is assessed at the end of the cardiopulmonary exercise testing to characterize a ventilatory limitation of the exercise test.
It is calculated as percent from the minute ventilation in relation to the maximum mandatory ventilation.
The measurement is a routine measurement during cardiopulmonary exercise testing.
