| Résumé : | Three patients who had undergone an orthotopic cardiac transplantation followed a course of supervised intermittent physical training (60 to 80 per cent of the maximum load) involving three weekly sessions of thirty minutes, for a period of 150 ± 80 days. During maximal effort, we observed increases of 50 per cent in the load in watts (0.05 < p < 0.1), 40 per cent in oxygen consumption (0.1 < p < 0.2), 10 per cent in heart rate (p = 0.5) and 21 per cent in systolic blood pressure (0.7 < p < 0.8). The respiratory equivalent for oxygen decreased by 21 per cent (0.025 < p < 0.05) and the respiratory quotient by 5 per cent (0.4 < p < 0.05). For a given submaximal effort (30 watts) the following decreases were observed: 9 per cent in oxygen consumption (V'O2) (0.1 < p < 0.2), 32 per cent in the minute ventilation (V'E) (0.05 < p < 0.1), 22 per cent in the respiratory equivalent for oxygen (REO2) (0.025 < p < 0.05), 8 per cent in the respiratory quotient (RQ) (0.2 < p < 0.3) and 11 per cent in the heart rate (HR) (0.1 < p < 0.2). The systolic blood pressure (SBP) increased by 6 per cent (0.2 < p < 0.3). No changes were observed in these parameters in the postoperative follow-ups (10 to 24 months) of two patients who did not undergo physical training. Physical training is, therefore, necessary in the process of physical readaptation of patients after orthotopic cardiac grafts. |
