30 patients with a previous myocardial infarction who had undergone diagnostic conventional left ventriculography and coronary arteriography had left ventriculography also performed by digital subtraction angiography after intravenous injection of contrast medium; the mean interval between the two investigations was 2.3 days. The conventional and the digital subtracted left ventricular images were computer-processed; global ejection fraction (obtained by the volumes calculated with the Dodge method) and segmental wall motion (from a quantitative analysis performed according to the Stanford method) were compared. We found a close correlation for the ejection fraction obtained by the two techniques (r = 0.89, p less than 0.01); absolute values proved to be slightly higher in the digital subtraction angiography. Segmental wall motion was significantly correlated too (p less than 0.05 for all the segments of the ventricular silhouette but for the one corresponding to the base of the heart). Digital intravenous angiography provides an accurate and less invasive method to evaluate left ventricular function.
30例曾患心肌梗死且已接受过传统诊断性左心室造影和冠状动脉造影的患者，在静脉注射造影剂后，通过数字减影血管造影术也进行了左心室造影；两次检查的平均间隔时间为2.3天。对传统的和数字减影后的左心室图像进行计算机处理；比较整体射血分数（通过Dodge法计算的容积获得）和节段性室壁运动（根据斯坦福方法进行的定量分析）。我们发现两种技术所获得的射血分数具有密切相关性（r = 0.89，p < 0.01）；数字减影血管造影术中的绝对值略高。节段性室壁运动也有显著相关性（心室轮廓的所有节段，除了对应心底的节段外，p < 0.05）。数字静脉血管造影术为评估左心室功能提供了一种准确且侵入性较小的方法。
