DISCUSSION
Previous studies have shown an impairment in the quality of life in patients with congestive heart failure.13 14 Our aim in the present study was to make a more detailed analysis of the relation between quality of life, the severity of the disease, and objective functional variables. Quality of life was assessed with a well validated questionnaire, the SF-36.15 16 For determining maximal and submaximal functional capacity, standard methods were employed. In order to ensure accuracy, all data were collected within a 48 hour period in each patient.
