摘要 目的探讨6分钟步行试验(6MWT)预期值和实测值的差值评估肺动脉高压患者肺动脉高压严重程度的临床价值。方法回顾性分析172例肺动脉高压患者的临床资料,分析其6MWT预期值和实测值的差值与肺平均动脉压(m PAP)、全肺阻力、心脏指数的相关性。结果 172例患者的6 min步行距离为(410. 7±67. 3) m,6 min步行预测距离为(768.5±81.4) m,预测值与实测值的差值为(347.8±76.6) m,m PAP为(65.6±18. 5) mm Hg,全肺阻力为(11. 7±6. 5) dyne·s·cm5,心脏指数为(5.7±4. 4) L/(min·m-2)。6MWT预期值和实测值的差值与m PAP呈正相关(P <0. 05),与全肺阻力及心脏指数无相关性(P> 0. 05)。结论 6 min步行距离实测值与预测值的差值可初步评估肺动脉高压患者肺动脉高压严重程度。
