碘酞六醇系非离子性造影剂,碘含量350mg/ml,与血清渗透压比为3.0。9例(陈旧性心肌梗塞6例,心绞痛3例)患者应用本药,称Ⅰ组。泛影葡胺(甲基葡萄糖胺66％,钠10％)为离子性造影剂,碘含量370mg/ml,与血清渗透压比为9.0,应用泛影葡胺的10例患者(全部为陈旧性心肌梗塞)称 D 组。两组全为男性,平均年龄、体重无差异。造影方法:用 Seldinger 法将带有测压计的导管插入右心和左心,以12ml/s 的速度注入造影剂40ml,4min 后重复1次,同时记录左室内压。摄 RAO30°左室像,计 Iodophtalalcohol nonionic contrast agent, the iodine content of 350mg / ml, and the serum osmotic pressure ratio of 3.0.9 cases (6 cases of old myocardial infarction, angina pectoris) in patients with the drug, said group Ⅰ. Meglumine diatrizoate (methylglucamine 66%, sodium 10%) is an ionic contrast agent with an iodine content of 370 mg / ml and a serum osmolarity of 9.0 and 10 patients with diatrizoate (all old Myocardial infarction) said D group. The two groups were all men, the average age, no difference in body weight. Contrast method: The Seldinger method with a manometer inserted catheter right heart and left heart, at a rate of 12ml / s injection of contrast agent 40ml, 4min after repeated 1, while recording left ventricular pressure. RAO30 ° left ventricular imaging, total
