摘要
为探讨急性心肌梗塞（ＡＭＩ）左室舒张功能的变化及影响因素，我们用脉冲多普勒超声心动图测量了７２例ＡＭＩ患者的左室舒张功能，并用多元逐步回归对其影响因素进行了分析。结果表明，７２例病人中Ｅ／Ａ＜１者４１例，占５６．９％。ＡＭＩ后左室舒张功能除受年龄影响外，梗塞面积的大小直接影响左室舒张功能，但与梗塞部位无关，梗塞前心绞痛可减轻梗塞后左室舒张功能的损害，是通过减小梗塞面积而实现的。溶栓治疗可以改善心肌梗塞后的左室舒张功能。
To invesitgate the factors influencing left ventricular diastolic function after acute myocardial infarction (AMI), left ventricular diastolic function was studied by Doppler echo cardiography in 72 patients (aged 59.19±10.24 yrs). Influencing factors were analyzed by multiple linear correlation and regrssion. Abnormal left ventricular diastolic function (E/A<1) was identified in 41 patients (41/72, 59.64%). Apart from age, the infarct size had an immediate effect on left ventricular diastolic function, where as infarct position did not. Angina pectoris befor infarction could reduce the impairment of left ventricular diastolic function by decreasing infarct size. Thrombolytic therapy could improve left ventricular diastolic function.
