摘要：Objectives To analyze the six-minute walk test (6MWT) and gas exchange of 5 heart transplantation patients and to approach the variation tendency of exercise tolerance,oxygen uptake (VO2) and heart rate chronotropic response.Methods 5 cases of heart transplantation patients (age 25～52 years) were undertaken 6MWT 6～30 months after operation,synchronizing gas exchanging parameters were measured by wireless portable remote sensing K4B2 gas analyzer,51 normal controls were compared.Results The six-minute walk distance (6MWD) of 5 patients were (592.61±26.7)m (558～625)m,the ascending tendency during exercise was slower,the maximum heart rates were 80%±6% of age-predicting maximal heart rate,lower than normal control (86%);the end point VO2/kg were (21.8±1.4)mL/min·kg(19.94～23.60)mL/min·kg.Conclusions The 6WMD and VO2 of 5 patients reached normal range,but the heart rate chronotropic response and VO2 ascending tendency were slower than those of normal controls.
