近年来心肺运动试验得到了越来越广泛的应用,在运动过程中通过对气体交换情况分析,可获得包括峰值摄氧量、无氧阈和二氧化碳当量斜率等在内的一系列临床指标。近年来的许多研究发现,峰值摄氧量和无氧阈是心功能的客观评价指标,基于这两个指标的Weber心功能分级可敏感发现早期心功能不全,并对预后有良好的预测价值。许多研究指出,二氧化碳当量斜率是慢性心力衰竭患者预后的独立预测因子之一。
In recent years, cardiopulmonary exercise test has been more and more widely used in the movement through the analysis of gas exchange can be obtained, including peak oxygen uptake, anaerobic threshold and carbon dioxide equivalent slope, a series of clinical indicators. In recent years, many studies have found that peak oxygen uptake and anaerobic threshold is an objective evaluation of cardiac function, based on these two indicators of Weber heart function grading can be sensitive to early detection of cardiac insufficiency, and the prognosis of a good predictive value. Many studies have pointed out that the slope of carbon dioxide equivalent is an independent prognostic factor in patients with chronic heart failure one of the predictors.
