The paper describes echocardiographic values of systolic and diastolic dysfunction the right heart ventricle in 229 patients with chronic obstructive pulmonary disease. In our patients the values AvPAP (?25 mmHg while resting), FDDrv and FSDrv (>26 and 20 mm respectively), the thickness of front wall the RV (>5 mm), the dimension of AD (>35 mm), as well as the reduction the vestibular-distal shortening of RV (<23%), maximum blood velocity and the blood evacuation time from reflect indirectly the progressive reduction the contractive capacity RV myocardium and the occurrence of systolic dysfunction. In patients with severe de-compensation a restrictive type diastolic function is more characteristic - acceleration of early diastolic filling and blood velocity decrease during the auricular systole.
该论文描述了229例慢性阻塞性肺疾病患者右心室收缩和舒张功能障碍的超声心动图值。在我们的患者中，静息时平均肺动脉压（≥25 mmHg）、右心室舒张末期内径（FDDrv）和右心室收缩末期内径（FSDrv）（分别>26和20 mm）、右心室前壁厚度（>5 mm）、右心房内径（>35 mm），以及右心室前庭-远端缩短率降低（<23%）、最大血流速度和右心室血液排空时间，间接反映了右心室心肌收缩能力的逐渐降低和收缩功能障碍的发生。在严重失代偿患者中，限制性舒张功能更具特征——舒张早期充盈加速，心房收缩期血流速度降低。
