扩张型心肌病和陈旧性心肌梗塞左室舒张晚期顺应性的观察

The Observation of Left Ventricular Late Diastolic Compliance with Dilated Cardiomyopathy and Old Myocardial Infarction

应用心尖搏动图的A波率和超声心动图的舒张晚期左室内径变化指数(VAW％),作为左室舒张晚期顺应性指标,观察其在扩张型心肌病(DCM)和陈旧性心肌梗塞(OMI)中的变化。结果:DCM和OMI(尤以左室扩大组)均有左室舒张晚期顺应性显著降低,并提示作为反映左室舒张晚期顺应性指标,A波率可能比VAW％更加敏感。DCM和OMI的EF和PEP/LVET均与对照组差异显著,表明两组兼有左室收缩功能和舒张晚期功能损害。VAW％可能对评价OMI有无左室扩大及予后有一定意义。

The 'A wave rate' from the apex cardiogram and the ventricular atrial wave rate(VAW%)from the M-echo-cardiogram are used as the indices of left ventricular (LV)late diastolic compliance to observe its variation in the dilated cardiomyopathy (DCM)and the old myocardial infarction(OMI).The LV late diastolic compliance (LDC)decreases in DCM and OMI (especially the LV dilated group) and indicates as an index of reflecting LV, LDC. The ' A wave rate' is pos- sible more sensitive than the VAW%. EF and PEP/LVET in DCM and OMI aresignificantly differance from the control group. It indicates that the two groups all have systolic and diastolic function disturbed. VAW% is possibly used to assess OMI with or without LV dialation and prognosis.
