Pulmonary artery pressure response to exercise was assessed using contrast enhancement of tricuspid regurgitation peak velocities in 19 patients with chronic congestive heart failure. Estimated systolic pulmonary artery pressures correlated closely with invasively measured pressures at rest (r=0.82, p <0.001) and during peak exercise (r=0.86, p <0.001) at a good level of agreement (mean difference 7.3 +/- 12 mm Hg), indicating that this method provides a reliable, noninvasive approach to evaluating functional reserve in patients with chronic congestive heart failure.
在19例慢性充血性心力衰竭患者中，通过三尖瓣反流峰值速度的对比增强来评估运动时的肺动脉压力反应。估计的收缩期肺动脉压力与静息时（r = 0.82，p <0.001）和运动峰值时（r = 0.86，p <0.001）的有创测量压力密切相关，一致性良好（平均差异7.3±12 mmHg），表明该方法为评估慢性充血性心力衰竭患者的功能储备提供了一种可靠的非侵入性方法。
