摘　　要：目的 探讨多普勒组织成像(DTI)技术评价慢性阻塞性肺病患者的左室舒张功能的应用价值。方法 慢性阻塞性肺病患者60例,正常对照组24例,应用多普勒组织成像技术及脉冲多普勒(PWD)技术检测二尖瓣环运动速度及二尖瓣口血流流速曲线进行对比分析。结果 与对照组比较,慢性阻塞性肺病患者E/A、Ea、e/a值有显著性差异(p<0.05),DTI技术对慢性阻塞性肺病患者左室舒张功能障碍的检出率高于PWD技术,DTI和PWD技术分别为86.7％和65％(P<0.05)。结论 慢性阻塞性肺病会引起左室舒张功能异常,DTI技术检测二尖瓣环运动速度之比评价左室舒张功能优于二尖瓣口血流流速曲线。Objective To evaluate left ventricular diastolic function of patients with chronic obstructive pulmonary disease by Doppler tissue imaging (DTI) . Methods There were 60 patients with chronic obstructive pulmonary disease enrolled in this study and another 24 cases were as normal controls. Pulsed Doppler (PWD) technique were used to measure the motion velocities of mitral valvula ring and mitral flow velocities of spectrum and these parameters were compared. Results E/A、Ea、e/a in patients with chronic obstructive pulmonary disease were lower than those of controls( p < 0.05) . The positive rate of left ventricular diastolic dysfunction by DTI was higher than PWD, 86.7 % vs 65 % respetively, p < 0.05. Contusion The abnormal left ventricular diastolic function is detected in patients with chronic obstructive pulmonary disease. The ratios of mitral valvular ring motion velocity for evaluating the left ventricular diastolic function by DTI is better than those of the conventional mitral flow velocity spectrum.
