缺血性心脏病左室收缩功能测定——左室数字减影、核素心室造影和超声心动图对比研究

Determination of Left Ventricular Systolic Function in Patients with Ischemic Heart Disease; A Comparitive Anatysis of Digital Subtraction Ventriculography Echocardiography and nuclide Ventriculography

本文利用左室数字减影(DSA)、核素心室造影(RNA)和超声心动图(UCG)对53名冠心病者和16名正常人进行左室收缩功能测定。结果示DSA与UCG改良Simpson氏和半球圆柱法相关性最好(r分别为0.84、0.70),与RNA法次之(r0.72),按有无节段性室壁运动障碍分组,则前壁运动障碍组DSA与UCG改良Sirepson和半球圆柱法相关性仍较好(r分别为0.84和0.82);下壁运动障碍组DSA与RNA和UCG相关性均较差。

To determine the clinic valune of left ventricular systolic function measured by digitial subtraction ventriculography (DSA). radionuclide ventriculography (RNA) and echocardiogrphy methods (UCG), 53 subjects with coronary heart disease and 16 normal controls were recuited. The results showd that, regardless the wall motion status, EF measured by DSA and UCG modified Simpson's rule. Half-ellipse cylinder method and RNA have good correlation (respectively, r=0.84, 0.79. 0.72, P<0.0001). Regarding the abnormality of left ventricular wall motion, comparitive analysis of three methods mentioned showd that EF measured by DSA and UCG modified Simpson's rule. Half-ellipse cylinder method and RNA have good correlation (respectively, r=0.81, 0.82, 0.58) in abnormal anterior wall motion group. EF measured by the methods mentioned above have-faily bad correlation in abnormal inferior wall motion. EF measured by UCG was higher than it by DSA.
