Advanced MRI Techniques and Applications

Clinical and necropsy findings are described in three patients who had angina pectoris at rest, S-T segment elevation on electrocardiography during chest pain, coronary arterial spasm on angiography and sudden death. Although significant "fixed" coronary narrowing (that is, narrowing due to atherosclerotic plaques) was appreciated by angiography in only one of the three patients, necropsy disclosed in all three patients severe fixed coronary narrowings involving particularly the artery in which spasm had been demonstrated during life. Additionally, examination of each 5-mm long segment of the coronary artery that had been spastic during life (two patients) disclosed several focally spastic segments at necropsy, indicating that spasm persisted after death. Although most previously described necropsy patients with Prinzmetal's angina had some fixed coronary narrowing, underlying fixed narrowing may be difficult to identify angiographically as demonstrated by the three patients in this study.
