心肌梗塞面积无损计测方法的临床研究(2)

^THE CLINICAL RESEARCH OF NO INJURED METHOD FOR THE MEASUREMENT OF MYOCARDIAL INFARCT SIZE

在动物实验的基础上，将计测心肌梗笨面积的数学模型应用于临床。与临床上应用的ＥＣＴ法、酶谱法进行对照实验，结果表明：（１）用模型法所测的结果与ＥＣＴ法（１４例患者）的结果相对照，两者极显著正相关（Ｐ＜０．０１）。（２）与酶谱法进行对照实验（１５例患者），呈极好的相关性。本实验在临床上进一步验证了计测心肌梗塞面积的数学模型，该法不仅计测梗笨面积准确、迅速，而且使用方便，造价低廉，在临床上有广阔的应用前景。

: The primary determinant of prognosis after acute myocardial infarction (AMI) is the size and the location of the myocardial infarction ,so it is important to detect the myocardial infarct size (MIS) accurately and quickly. we have proposed a tnew method to detect AMI size with Frank orthogonal ECG on the mathematical model. The results suggest that : (1) The relationship between the model and CPK is statisticaly significant(r=0.950,p<0.01).(2) NIS (ranges fron 4 to 16 cm2) obtained by the model and ECT method (the Emission Computed Tomograpng Imaging ofMIBT 99mTc on patients )had been com- pared, there are significant positive correlation between the two groups data(r=0.910,P<0.01).The location of myocardial infarction detected by the two methods agrees with each other well. This new method could be used to advantages than any other current methods detecting MIS and location.
