Left ventricular ejection fraction was determined in 114 patients by radionuclide and contrast angiocardiography. The correlation coefficient (r) amounted to 0.66. Exclusion of patients with arrhythmias and with a difference in heart rate exceeding 15 beats per minute between the two determinations of the ejection fraction increased r to 0.80 (61 patients). In patients with coronary artery disease and cardiomyopathies (n = 35), r was higher (0.88) than in patients (n = 26) with acquired valve disease or congenital heart disease (0.60). Comparison of first pass radionuclide angiocardiography and gated blood pool scanning with contrast angiocardiography in 19 patients elicited an r-value of 0.82 for the first pass method and of 0.31 for gated blood pool scanning. Visual assessment of local wall motion by gated blood pool scanning in 15 patients showed agreement with cineangiographically quantitated segmental motion (normo-, hypo- or a-kinesis) in 50 of 60 (= 83%) evaluated segments.
通过放射性核素和造影心动图对114例患者测定左心室射血分数。相关系数（r）为0.66。排除心律失常患者以及两次射血分数测定时心率差异超过每分钟15次的患者后，r值增至0.80（61例患者）。在冠状动脉疾病和心肌病患者（n = 35）中，r值（0.88）高于获得性瓣膜病或先天性心脏病患者（n = 26）（0.60）。对19例患者进行首次通过放射性核素心动图和门控血池扫描与造影心动图的比较，首次通过法的r值为0.82，门控血池扫描的r值为0.31。15例患者通过门控血池扫描对局部室壁运动进行视觉评估，结果显示，在60个评估节段中的50个（= 83%）节段中，与电影血管造影定量节段运动（正常、运动减弱或运动不能）一致。
