Arm exercise training in the rehabilitation of patients with impaired ventricular function and heart failure.

Although exercise training is an accepted part of comprehensive coronary care programs in patients with coronary artery disease, it still remains to be demonstrated whether or not exercise training should also be applied to patients with impaired ventricular function. Circumstantial evidence exists that patients with impaired ventricular function may eventually benefit from an individually adapted exercise training program provided that contraindications for acceptance of cardiac patients to such a program are well observed. Our study is based on 22 patients with impaired ventricular function, of which 18 were at least 6 months after a Q-wave myocardial infarction and the remaining 4 after coronary artery bypass grafting.

Exercise tolerance in patients on chronic hemodialysis.

Twenty-two patients on chronic hemodialysis were tested on a bicycle ergometer to determine their near-maximal physical work capacity. The patients were found to have low physical work capacity that averaged 51.6 +/- 3.
