In addition to the conventional indices of radionuclide angiography with ECG-gait in equilibrium, the authors determined the volume indices of the left ventricle at rest by the so-called nongeometric method in 30 patients with ischemic heart disease. Patients without myocardial infarct (13 subjects) had decreased total left-ventricular ejection fraction (EF), as a result of increase in the end systolic volume index (ESVI) in one of the tested patients. Changes in the regional fractions and in the wall kinetics were detected in 6, resp. in 8 patients. Patients with myocardial infarct--13 subjects--had decreased total left ventricular EF, as a result increased ESVI in 4 patients. Disturbances in the regional fraction and in the wall kinetics had 9 patients. Estimated for the whole group, the mean ESVI level was significantly higher than in the former group of patients. Patients with postinfarction aneurysm, in addition to the marked decrease of the total left ventricular EF, had increased and-systolic and diastolic volume index, which in some of the patients was associated with reduced stroke volume index. The minute flow levels were significantly lower than in the former two groups. Determination of the volume indices is an important supplement to the efforts to gain precise information on the functional state of the left ventricle and for evaluation of the hemodynamics and of the effect of complications which occur with the advancing of the ischemic heart disease.
除了常规的平衡状态下带心电图同步的放射性核素血管造影指标外，作者采用所谓的非几何学方法，对30例缺血性心脏病患者静息时的左心室容积指标进行了测定。无心肌梗死的患者（13例）中，有1例受试患者的左心室总射血分数（EF）降低，这是由于收缩末期容积指数（ESVI）增加所致。分别在6例和8例患者中检测到局部射血分数和室壁动力学的变化。有心肌梗死的患者——13例——左心室总EF降低，4例患者的ESVI增加。9例患者存在局部射血分数和室壁动力学紊乱。就整个组而言，平均ESVI水平显著高于前一组患者。心肌梗死后动脉瘤患者，除左心室总EF显著降低外，收缩末期和舒张期容积指数增加，部分患者的每搏量指数降低。每分血流量水平显著低于前两组。容积指标的测定是获取左心室功能状态精确信息、评估血流动力学以及缺血性心脏病进展过程中出现的并发症影响的重要补充手段。
