2、value of the exercise test is maximized,when multiple exercise findings are considered and it seems,that respiratory gas analysis offers new perspectives in this sense.Cardiologists should realise that with CPET we have an enormously powerful tool to our disposal.European Heart Journal 2003Volume 24

5、e test results have been established as outstanding prognostic information.,心肺运动试验(CPET)定义,CPET可提供一个包括呼吸系统，心血管系统，造血系统以及骨骼肌系统综合运动反应的整体评估，这是测定单一器官系统功能所无法充分反应的。该试验具有无创、动态、生理性的特点。,慢性心力衰竭心预后的评估,目前最常用的是Weber-Janicki 分级,Peak oxygen pulse during exercise as a predictor for coronary heart disease and all cau

7、of 14 years,267 men died,67 of them due to CHD.The respective risk for overall death was 1.79(95%CI 1.21 to 2.65).,心肺运动试验与冠心病及预后,P0.0001,P0.0001,0,10,20,30,40,50,60,70,80,90,VO2/pulse13.5ml,死亡率,VO2/pulse17.5ml,冠心病发病率,2.45倍(95%CI 1.10 to 5.45),1.79(95%CI 1.21 to 2.65),VO2分层及预后的评估,Survival curves for
