Exercise stress tests of the pulmonary circulation show promise for the detection of early or latent pulmonary vascular disease and may help us understand the clinical evolution and effects of treatments in patients with established disease. Exercise stresses the pulmonary circulation through increases in cardiac output and left atrial pressure. Recent studies have shown that exercise-induced increase in pulmonary artery pressure is associated with dyspnea-fatigue symptomatology, validating the notion of exercise-induced pulmonary hypertension. Exercise in established pulmonary hypertension has no diagnostic relevance, but may help in the understanding of changes in functional state and the effects of therapies.
运动心肺压力测试有望用于早期或隐匿性肺血管疾病的检测，并且可能有助于我们了解已确诊疾病患者的临床演变和治疗效果。运动通过增加心输出量和左心房压力来使肺循环紧张。最近的研究表明，肺动脉压力在运动时的增加与呼吸困难-疲劳症状有关，这验证了运动性肺动脉高压的概念。在已确诊的肺动脉高压中，运动没有诊断意义，但可能有助于了解功能状态的变化和治疗效果。
