The patients with chronic heart failure and mitral regurgitation (>moderate) were performed ergometer stress echocardiography. We divided two groups (asymptomatic group vs symptomatic group). After ergometer stress, 59% in symptomatic group and 64% in asymptomatic group has exercise induced pulmonary artery hypertension. Multivariate regression analysis revealed that baseline pulmonary artery pressure and the change in left atrial systolic strain rate from baseline to 10W exercise were independent predictors for exercise induced pulmonary artery hypertension.

具有慢性心力衰竭和二尖瓣反流（>中度）的患者进行了肌计应力超声心动图。我们划分了两组（无症状组与有症状的组）。测量表应激后，有症状的组为59％，无症状组为64％的肺动脉高压。多元回归分析表明，从基线到10W运动的左心房收缩期应变率的变化是运动诱导的肺动脉高压的独立预测指标。
