In 12 patients with high-grade coronary stenosis local motility before and after aortocoronary vein bypass was estimated by cineradiography of coronary bifurcations and surgically implanted myocardial metal markers. A group of patients with relief of angina showed significant increase of local segment shortening within the first postoperative days. During the following months no further alteration occurred. In three patients with persisting angina no improvement of local motility could be found.
对12例冠状动脉高度狭窄患者，在主动脉 - 冠状动脉静脉搭桥术前及术后，通过冠状动脉分叉处的电影血管造影术和手术植入的心肌金属标记物来评估局部心肌运动。一组心绞痛缓解的患者在术后最初几天内局部节段缩短明显增加。在接下来的几个月里没有进一步变化。3例持续性心绞痛患者未发现局部心肌运动改善。
