title: [Efficiency of patients with chronic renal failure (author's transl)].
abstract: In 77 patients with chronic renal failure - all were conservative treated - exercise-tests were performed with the bicycle and in 67 cases spiro-ergometric tests. We found a correlation between the decrease of hemoglobin and the decrease of efficiency and a linear function between the decrease of hemoglobin and the increase of creatinin in serum. There was no direct correlation between the increase of creatinin and the decrease of efficiency. The efficiency, measured in Watt, and the oxygen pulse correlated. More patients with hypertonia exceeded the level of 70 of the quotient heart volume/oxygen pulse but those with normal pressure. The efficiency was reduced in general: only 13,4% obtained 100 Watt, 28,4% 75 Watt and the rest of 58,2% were of bad efficiency and performed only 50 Watt or less.
