导言和说明
肥胖对心脏功能的影响仍在讨论中。本研究的目的是评估病态肥胖患者的心肺功能。病人和方法。对31例病态肥胖患者（BMI 50 9 kg/m2）和30例正常对照者（BMI 24 2 kg/m2）进行了限制性心肺运动负荷试验。使用氧脉搏（摄氧量/心率）评价心血管功能。
结果
两组之间在年龄、性别和身高方面无差异。在运动过程中，肥胖组的摄氧量、心率、收缩压和每分钟通气量均显著高于对照组（14.3vs27.4min; P < 0.001）。肥胖患者的氧脉搏值较高。然而，在通过去脂质量不依赖氧摄取后，这些差异消失，表明类似的心血管功能。在运动结束时，对照组达到了他们年龄预测的最大心率的96%，他们的呼吸交换率为10.2。肥胖患者仅分别达到86%和0.87 ± 0.2。
结论
由于他们需要更多的能量输出来移动总的身体质量，病态肥胖患者的运动能力降低。他们完成了次极量运动的测试。然而，在此过程中，他们表现出正常的心肺功能。
INTRODUCTION AND OBJECTIVES
The effect of obesity on cardiac function is still under discussion. The objective of this study was to assess cardiopulmonary capacity in morbidly obese patients. Patients and method. A symptom-limited cardiopulmonary exercise stress test was carried out in 31 morbidly obese patients (BMI 50 9 kg/m2) and 30 normal controls (BMI 24 2 kg/m2. Cardiovascular function was evaluated using the oxygen pulse (oxygen uptake/heart rate).
RESULTS
There were no differences in age, sex and height between both groups. During the effort the obese subjects presented greater oxygen uptake, heart rate, systolic arterial pressure and minute ventilation and shorter test duration than control group (14 3 vs 27 4 min; p < 0.001). Oxygen pulse values were higher in obese patients. However, after oxygen uptake indexation by fat free mass, these differences disappeared, suggesting a similar cardiovascular function. At the end of the exercise, the control group reached 96% of their age-predicted maximal heart rate and their respiratory exchange ratio was 1 0.2. Obese patients only reached 86% and 0.87 0.2, respectively.
CONCLUSIONS
Due to their need of more energy output to move total body mass morbidly obese patients have a reduced exercise capacity. They finish the test having done a submaximal exercise. However, during this effort they show a normal cardiopulmonar capacity.
