Factors limiting physical working capacity in predialytic uraemic patients
The exercise capacity of 20 predialytic uraemic patients (mean age 43 ± 12 years) was studied prospectively. Nine of these patients were examined twice in a longitudinal study. The maximal working capacity, measured by standardized exercise test on a bicycle ergometer, averaged 74 ± 19% of the expected normal. Normal exercise ECG were registered in 16 out of 20 patients.
