摘要 目的 探讨 6分钟步行试验 (6-MWT)对评价慢性心力衰竭 (CHF)患者预后的价值。方法  188例病情稳定的CHF患者 ,采用“滴定法”正规治疗 ,治疗前后 2次进行 6-MWT ,以步行距离增加 2 0 %为标准 ,分为A组(<2 0 % )、B组 (≥ 2 0 % ) ,随访 1年。结果  2组一般情况无差异 ,治疗前后步行距离A组分别为 (3 12± 65)m、(3 50± 58)m(P <0 .0 1) ,B组分别为 (3 18± 76)m、(42 6± 80 )m(P <0 .0 1)。 1年内病死率A组高于B组 (13 .5%、3 .7% ,P <0 .0 5) ,因心衰住院率A组 2 5%、B组 9.3 % (P <0 .0 1)。结论  6-MWT步行距离增加 <2 0
