测量了１２６例急性心肌梗塞患者发病２周后梗塞面积和左室功能，结果发现梗塞面积、左室射血分数、左室舒张末内径与梗塞并发症的严重程度有明显关系．梗塞面积与左室射血分数仅呈中度负相关，而与左室舒张末内径则不相关．但左室射血分数与左室舒张末内径则呈中度负相关．因此可以认为，梗塞面积、射血分数、左室舒张末内径和冠状动脉病变与急性心肌梗塞并发症的关系是既互相关联又彼此独立，应该综合考虑．
The infarct size and left ventricular function were measured in 126 patients with acute myocardial infarction 2 weeks after onset. The infarct size, left ventricular ejection fraction, and left ventricular end-diastolic diameter were significantly correlated with the severity of infarction complications. Infarct area and left ventricular ejection fraction only a moderate negative correlation with the left ventricular end diastolic diameter is not related. However, left ventricular ejection fraction and left ventricular end diastolic diameter showed a moderate negative correlation. Therefore, it can be considered that the relationship between infarct size, ejection fraction, left ventricular end-diastolic diameter, and coronary artery disease and acute myocardial infarction complications is both interrelated and independent of each other and should be taken into consideration.
