在冠心病患者,左室容积是最有力的存活预报。心肌梗塞后不久,左室即开始扩大。急性期的心腔扩大主要是梗塞区的扩大,而非梗塞区的扩大也可引起整个心室的扩大。已显示心肌梗塞的心室终末容积与梗塞范围大小有关,往往可由不能运动或运动障碍的心室轮廓的比例来估计。在实验性心肌梗塞的动物中,心室腔的增大取决于梗塞范围的大小。由组织学证实,梗塞区治愈后,心腔的扩大还是存在。冠状
In patients with coronary heart disease, left ventricular volume is the most powerful prognosis of survival. Shortly after myocardial infarction, left ventricle began to expand. Acute cardiac enlargement is mainly the expansion of the infarct area, while the expansion of non-infarction area can also cause the expansion of the entire ventricle. It has been shown that the terminal ventricular volume of a myocardial infarction is related to the size of the infarct size and can often be estimated from the proportion of ventricular profiles that are not motor or dyskinesia. In experimental myocardial infarction animals, the increase of the ventricular cavity depends on the size of the infarct size. Confirmed by histology, infarction area after the cure, the expansion of the heart chamber still exists. Coronal
