Seventeen male OHT recipients, ranging in age from 22 to 60 years, participated in this study 47 ± 21 days after surgery. The control group consisted of 17 sedentary healthy men. Breath-by-breath measurement of cardiorespiratory function was obtained during the incremental exercise of leg cycling. At peak exercise, the oxygen (O2) uptake (16.5 ± 3.3 vs 33.9 ± 8.2 mL·kg-1·min-1), work rate (82 ± 19 vs 169 ± 42 watts), heart rate (HR), O2 pulse, and blood lactate level of the OHT recipients were significantly lower than the respective values of the control group. At the ventilatory threshold, the OHT group also showed a significantly lower O2 uptake (10.7 ± 1.6 vs 18.3 ± 5.1 mL·kg- 1·min-1), work rate (39 ± 12 vs 89 ± 33 watts), HR, O2 pulse, ventilatory equivalent for O2, and ventilatory equivalent for carbon dioxide. The OHT recipients showed a high resting HR (97 ± 7 beats/min) and a low peak HR (123 ± 14 beats/min) during exercise, and their HR continued to increase for 1 to 3 minutes after cessation of exercise. Our data revealed a low level of cardiorespiratory endurance in OHT recipients during the early postoperative stage. A multidisciplinary cardiac rehabilitation program should be considered to enhance physical functional capacity and quality of life, and promote return to work. |
