摘要
对２３例慢性充血性心力衰竭（ＣＨＦ）患者（ＮＹＨＡⅡ级８例，Ⅲ级１５例）进行６分钟步行试验，并与运动峰耗氧量（ＰＶｏ＿２）试验对比。结果显示：ＮＹＨＡ分级与Ｗｅｂｅｒ′ｓ分级符合率为５６．５％，运动时间、运动功率及二次６分钟步行距离与ＰＶｏ＿２均显著相关（分别为Ｐ＜０．０５、Ｐ＜０．０２、Ｐ＜０．０２、Ｐ＜０．００２）。６分钟步行距离第二次较第一次稍增加，但无统计学差异，且显著相关（Ｐ＜０．００１），重复性较好。逐步回归分析显示：６分钟步行距离与ＰＶｏ２相关最密切。提示６分钟步行距离优于运动时间和运动功率，可替代ＰＶｏ２作为一种简便易行的运动耐量试验。
Abstract Six minute walking test and peak oxygen consumption(PVo2) were measured in 23patients with chronic heart failure ( NYHA classification Ⅱ～Ⅲ).The results indicated that the compatibility rate of the NYHA classification and the Weber′s class was 56.5%,the exercise time,watt and the distance walked in six minutes correlated well with PVo2(P<0.05,P<0.02,P<0.02 and P<0.002 respectively).The distance walked in two successive tests increased slightly,but without significant statistical difference,and correlated each other significantly(P<0.001),indicating the nice reproducibility. The step regression analysis showed that the distance walked in six minutes correlated most significantly with PVo2 than exercise time and watt,and could be used as an easy and convenient parameter to evaluate the exercise tolerance.
