碘化造影剂(Iodinated contrast material)泛影甲葡胺(Diatrizoate meglumine)、碘海醇(Iohexol),虽能产生一过性冠脉充血,但血管扩张作用不足,无应用价值。仅在冠脉注射时才明显增加冠脉血流(使正常冠脉血流速度增加3.1±0.2倍)。罂粟碱(Papaverine)强效冠脉扩张剂,正常人冠脉注射(12mg)使冠脉血流增加4.8±0.4倍。注射后17±13秒钟出现最大效应,持续29±3秒钟;平均129±16秒钟
Iodinated contrast material Diatrizoate meglumine, Iohexol, although can produce transient coronary congestion, but the vasodilator effect is not enough, no application value. Coronary flow was significantly increased only at coronary injection (3.1 ± 0.2 times normal coronary flow). Papaverine potent coronary dilators, normal coronary injection (12mg) increased coronary blood flow 4.8 ± 0.4 times. The maximum effect occurs 17 ± 13 seconds after injection for 29 ± 3 seconds; an average of 129 ± 16 seconds
