本文以右室心内膜活组织检查为基准,评价~(111)铟标记的单克隆抗肌凝蛋白抗体显象诊断心肌炎的意义。 28(男15、女13)例50±3岁患者临床拟诊为心肌炎,经造影排除冠状动脉病变,其中25例左室喷血分数(LVEF) <45％,平均27±2％;另3例LVEF>45％。右室活检取材6～7块,直径1～3mm。根据光学显微镜所见分为心肌炎、非特异性变化和正常。首次左室造影采用放射性核素法(24例)或X线造影(4例),6个月后均用核素法复查。符合下列条件者为心功能改善:LVEF增加10％以上;X线心胸比率缩小;心力衰竭改善(NYHA)1级以上。皮肤试验无
In this paper, right ventricular endocardial biopsy as the benchmark, evaluation of ~ (111) indium labeled monoclonal anti-myosin antibody imaging diagnosis of myocarditis significance. 28 (male 15, female 13) cases 50 ± 3 years old patients clinically diagnosed as myocarditis, angiography exclude coronary artery disease, of which 25 cases of left ventricular ejection fraction (LVEF) <45%, an average of 27 ± 2%; the other 3 Example LVEF> 45%. Right ventricular biopsy drawn 6 to 7, a diameter of 1 ~ 3mm. According to the optical microscope is divided into myocarditis, non-specific changes and normal. The first time left ventricular angiography by radionuclide method (24 cases) or X-ray (4 cases), 6 months after the nuclide method review. Those who meet the following conditions for improvement of cardiac function: LVEF increased by 10% or more; X-ray ratio of thoracic contraction; improvement of heart failure (NYHA) more than one.
