To evaluate the relationship of the exercise capacity in patients with stable moderate to severe chronic obstructive pulmonary disease(COPD) with the lung function tests, especially the inspiratory capacity(IC).
Methods
Pulmonary lung function test(PFT) and cardiopulmonary exercise test(CPET) were tested in 62 patients with stable moderate to severe COPD and 30 controls, and measured the parameters of ventilation and gas exchange.
Results
IC%pred was significant associated with exercise capacity(r=0.74, P<0.001)in COPD, it has significant validity of the prediction to peak O2%pred.
Conclusions
IC%pred provides the efficient information to estimate the exercise capacity in patients with stable COPD, and its predictive value is better than other parameters.
