In contrast, vasospastic angina shows ST-segment elevation due to transmural ischemia.

相反，血管痉挛型心绞痛因透壁性缺血显示ST段抬高。

In the absence of treatment, the process may progress to complete transmural infarction of the area involved with development of pathological Q waves.

在没有治疗的情况下，这一过程可能进展到与病理性Q波发展有关的区域的完全跨壁梗死。

Unlike both stable and unstable angina, in this case the coronary artery's constricted so severely that all layers of the heart wall being supplied are affected, therefore it's referred to as transmural ischemia.

与稳定型、非稳定型不同，这种情况下冠状动脉极度收缩，心壁所有层都受影响，因此，也被称为透壁性缺血。
