慢性肺心病对左心室舒张功能的影响

评价慢性肺源性脏病对左心功能的影响，方法采用ＵＣＧ技术对３０例肺心病患者左心功能进行研究，并与同年龄组正常人进行对照。结果显示肺心病患者组左心室舒张早期充盈率与Ｅ峰减速率明显低于对照组，而左心室舒张晚期充盈率，舒张晚期与舒张早期充盈率的比值则明显高于对照组，肺心病组左心病射血分略高于对照组，每搏排血量测显著减低，结论：肺心病患者存在明显的左心室舒张功能障碍。

Effects of chronic cor pulmonale on left ventricular diastolic function

Objective: To evaluate the effect of chronic cor pulmonale on left ventricular function Methods: In 30 cases with chronic cor pulmonale, left venticular functions were estimated by ultra cardiography, as compared with those in that normal subjects of age matched Results: In the patient group the early diastolic filling velocity of left ventricle (the peak E of mitra valve flow) and the decelerated rate of peak E of mitral valve flow were decreased, However the late diastolic filling velocity (the peak A of mitral valve flow) and the peak A/E were increased significantly ( P <0 01) The left ventricular EF was higher than the normal value( P <0 05), but SV was decreased ( P <0 01) Conclusion: Significant disturbence of left ventricular diastolic function exists in the patients with chronic cor pulmonale
