The symptom-limited exercise test is nowadays the gold standard to assess the exercise tolerance and the effects of different treatments in patients with chronic heart failure (CHF). A simpler alternative to this test is the 6-minute walk test. The 6-minute walk test is easy to realize and well-tolerated. Moreover, it is reliable just after one familiarization practice and requires standardization. Indeed, its conduction, which is submitted to some security precautions, can be altered by variation factors. The distance walked during the 6 minutes was the only parameter studied during the test. This parameter could allow judging the CHF severity and prognostic. The analyse of cardiorespiratory parameters has shown that the 6-minute walk test relative intensity is near to the peak individual values. Moreover, the cardiac and ventilatory adaptation of patient during this test depends to his own functional capacity. Lastly, the 6-minute walk test is a submaximal constant-load exercise, which should be performed in complement to the symptom-limited exercise test in cardiac patients.
症状限制性运动试验是目前评估慢性心力衰竭（CHF）患者运动耐力及不同治疗效果的金标准。该试验的一种更简单替代方法是6分钟步行试验。6分钟步行试验易于实施且耐受性良好。此外，只需经过一次熟悉练习它就很可靠，并且需要标准化。实际上，其实施虽需采取一些安全预防措施，但可能会因各种因素而改变。6分钟内行走的距离是该试验中唯一研究的参数。这个参数可用于判断CHF的严重程度和预后。对心肺参数的分析表明，6分钟步行试验的相对强度接近个体峰值。此外，患者在该试验中的心脏和通气适应性取决于其自身的功能能力。最后，6分钟步行试验是一种次极量恒定负荷运动，应作为心脏病患者症状限制性运动试验的补充进行。
