Cycle and treadmill exercise tests are unsuitable for elderly, frail and severely limited patients with heart failure and may not reflect capacity to undertake day-to-day activities. Walking tests have proved useful as measures of outcome for patients with chronic lung disease. To investigate the potential value of the 6-minute walk as an objective measure of exercise capacity in patients with chronic heart failure, the test was administered six times over 12 weeks to 18 patients with chronic heart failure and 25 with chronic lung disease. The subjects also underwent cycle ergometer testing, and their functional status was evaluated by means of conventional measures. The walking test proved highly acceptable to the patients, and stable, reproducible results were achieved after the first two walks. The results correlated with the conventional measures of functional status and exercise capacity. The authors conclude that the 6-minute walk is a useful measure of functional exercise capacity and a suitable measure of outcome for clinical trials in patients with chronic heart failure.
踏车运动试验和跑步机运动试验不适用于老年、体弱及心力衰竭严重受限的患者,且可能无法反映其进行日常活动的能力。步行试验已被证明是评估慢性肺病患者预后的有效方法。为了研究6分钟步行试验作为慢性心力衰竭患者运动能力客观指标的潜在价值,在12周内对18例慢性心力衰竭患者和25例慢性肺病患者进行了6次该试验。受试者还进行了蹬车测力计测试,并通过传统方法评估了他们的功能状态。结果表明,患者对步行试验接受度很高,在前两次步行后即可获得稳定、可重复的结果。这些结果与功能状态和运动能力的传统测量方法相关。作者得出结论,6分钟步行试验是评估慢性心力衰竭患者功能性运动能力的有效指标,也是此类患者临床试验合适的预后评估指标。
