冠心病急性心肌梗塞(AMI)以其临床表现危笃而著称,由于功能性心肌量的丧失,常有不同程度泵功能损伤(心室容量增加、喷血分值EF下降等),急性期难以应用创伤性方法测定,本研究采用扇形切面超声记波(CSuKG)方法,因心室内膜面清楚,测量较准确,为非创伤方法测定左室容量和EF的有效方法;分期左室内径平均缩短速率是反映心肌收缩性的敏感指标,目前资料未见报导。 Coronary heart disease acute myocardial infarction (AMI) is known for its clinical manifestations of Danwei, due to the loss of functional cardiac muscle, often varying degrees of pump dysfunction (increased ventricular volume, EF decline in spurt score, etc.), the acute phase is difficult to apply Traumatic method to determine the use of fan-shaped section of the ultrasonic wave (CSuKG) method, because the ventricular membrane surface clear, accurate measurement of non-invasive method for the determination of left ventricular volume and EF effective method; staged left ventricular diameter average rate of shortening Is a sensitive indicator of myocardial contractility, the current data have not been reported.
