In order to determine the hemodynamics and pulmonary function during exercise, 20 patients with chronic lung disease complicated with (group A) or without (group B) pulmonary hypertension were studied. FEV1% in group A was lower than that in group B at rest, the increase in VE, VO2, O2-pulse in patients with pulmonary hypertension were lower than in patients without it during exercise. We speculated that exercise ability in patients with chronic lung disease may be effected by not only ventilation but also increased pulmonary arterial pressure.
为了确定运动期间的血流动力学和肺功能，对20例合并（A组）或未合并（B组）肺动脉高压的慢性肺病患者进行了研究。A组静息时的第一秒用力呼气容积百分比低于B组，运动期间肺动脉高压患者的每分通气量、摄氧量、氧脉搏增加幅度低于无肺动脉高压的患者。我们推测慢性肺病患者的运动能力可能不仅受通气影响，还受肺动脉压升高的影响。
