【摘要】 目的 :研究心梗后患者的左室重构和心功能变化。方法 :应用多普勒超声心动图研究 6 6例心梗后患者 (心梗组 )和 6 6例无器质性心脏病者 (对照组 )的左室重构和心功能变化。结果 :心梗组LVDd、LVDs较对照组明显增大 (P <0 .0 5 )而CI、LVEF显著降低 (P <0 .0 1) ,DT、IVRT延长 (P <0 .0 1)。E A比值减少。结论 :梗塞膨展和心室扩张是心梗后左室重构的主要病理过程 ,左室重构对心脏收缩和舒张功能产生不良影响 ,多普勒超声心动图对心梗后左室重构和心功能的分析有重要的意义更多还原

【Abstract】 Objective:To evaluate the LVR and CF in patients after MI.Methods:Doppler Echocardiographic indexes of LVR and CF were analysed in 66 patients after MI(MI group)and 66 normal subjects(The control group).Results:LVDd and LVDs were larger in MI group than those in the control group( P <0.05).While CI and LVEF were significantly decreased( P <0.01).DI and IVRT were prolonged in the patients after MI.These patients also had a smaller E/A than the control group.Conclusion:Infarction expansion and ventricular enlargment are the main pathological courses of LVR in patients after MI.And LVR can cause a unfavourable effect on cardiac systolic and diastolic functions.Doppler echocardiography have great values in studying LVR and CF in these patients.更多还原
