28 patients with primary congestive cardiomyopathy in heart failure identified by cineangiographic criteria (end-diastolic volume greater than 120 ml/m2; parietal thickness less than 11 mm; normal coronary angiography), underwent 131-Cesium and 201-Thallium myocardial scintigraphy in antero-posterior and LAO projections, and 17 also underwent angiocardiography with 99 Technetium labelled albumin. This condition usually gives an appearance of an enlarged heart with diffuse or localised (antero lateral wall) hypofixation, dilatation of the left ventricular, left atrial and right ventricular cavities and a very low ejection fraction with diffusely hypokinetic wall motion. Radio-Isotopic methods may help discriminate primary and ischaemic cardiomyopathy but are not diagnostic. A low ejection fraction and marked diffuse hypofixation are poor prognostic indices. Radio-Isotopic methods are valuable in the classification of primary cardiomyopathy.
28例经心血管造影标准确诊为原发性充血性心肌病伴心力衰竭的患者（舒张末期容积大于120 ml/m²；壁厚度小于11 mm；冠状动脉造影正常），接受了前后位和左前斜位的¹³¹铯和²⁰¹铊心肌闪烁扫描，其中17例还接受了⁹⁹锝标记白蛋白的心腔造影。这种情况通常表现为心脏扩大，伴有弥漫性或局限性（前侧壁）放射性摄取减低、左心室、左心房和右心室腔扩张以及射血分数极低且室壁运动普遍减弱。放射性同位素方法可能有助于鉴别原发性和缺血性心肌病，但不具有诊断性。低射血分数和明显的弥漫性放射性摄取减低是不良的预后指标。放射性同位素方法在原发性心肌病的分类中很有价值。
