一、急性心肌梗塞的左室功能测定急性心肌梗塞的严重程度取决于梗塞区域的范围大小,后者直接影响左心室的运动功能,因此通过左心室壁运动功能测定对病情估计有重要的价值。研究分三个阶段:(1)急性期(平均梗塞后2.7天);(2)恢复期;(3)随诊阶段。主要采用选择性冠状动脉造影及左心室电影血管造影等检查技术。【急性期】 1.评价急性心肌梗塞左心室总的和局部的功能变化。将心肌梗塞按病情分为四级;Ⅰ级,左心室功能正常;Ⅱ级,轻度左心功能不全;Ⅲ级,伴有肺水肿;Ⅳ级,伴有心源性休克。
First, acute myocardial infarction of left ventricular function determination of the severity of acute myocardial infarction depends on the size of the infarct size, the latter directly affect the left ventricular motor function, so through the left ventricular wall motion function assessment of the disease has important value. The study was divided into three phases: (1) acute phase (average 2.7 days after infarction); (2) recovery; (3) follow-up stage. The main use of selective coronary angiography and left ventricular angiography and other inspection techniques. [Acute phase] 1. Evaluation of acute myocardial infarction left ventricular total and local changes in function. Myocardial infarction according to the disease is divided into four; Ⅰ, normal left ventricular function; Ⅱ, mild left ventricular dysfunction; Ⅲ, with pulmonary edema; Ⅳ, with cardiogenic shock.
