In order to clarify the fate of coronary narrowing with spasm, repeat angiograms of coronary narrowing with and without spasm were compared. The mean interval between the first and second angiograms was 3.6 years (range, 1.1-8.5 years). Improvement of narrowing was more frequent in the vasospastic group (23%) than in the group without spasm (3%, P < 0.005). The cause of this improvement in the vasospastic group may have been the resolution of the spasm in the first angiogram, but the presence of intravascular thrombus or bleeding or edema of the coronary arterial wall may have resolved in the second angiogram.
为了阐明伴有痉挛的冠状动脉狭窄的转归，对伴有和不伴有痉挛的冠状动脉狭窄的重复血管造影结果进行了比较。首次和第二次血管造影之间的平均间隔时间为3.6年（范围为1.1 - 8.5年）。血管痉挛组狭窄改善的发生率（23%）高于无痉挛组（3%，P < 0.005）。血管痉挛组这种改善的原因可能是首次血管造影时痉挛得到缓解，但也可能是第二次血管造影时血管内血栓、出血或冠状动脉壁水肿已消退。
