Plaque characterization and atherosclerosis evaluation by coronary angioscopy.

摘要: When observed by angioscopy, the culprit lesions of acute coronary syndrome (ACS) have a common appearance yellow plaque with irregular surface covered thrombus. Angioscopy is powerful device to detect not only ruptured plaques at ACS but also in their early stages. The are sometimes detected angioscopy even angiographically normal segments arteries. can further classify as (1) vasospasm, (2) rupture, or (3) erosion according angioscopic definitions. These classifications may be beneficial determine treatment strategy. Anti-vasospastic medications rather than stenting more suitable for vasospasm-induced ACS. Percutaneous intervention (PCI) erosive tends cause distal embolization thrombus and contents. Therefore, protection those cases. Although able identify vulnerable intensive color, it practical patients high risk suffering evaluating extent atherosclerosis. process time course formation, maturation, disruption left clarified, however, number color intensity marker should useful diagnostic tool an investigational tool. effect that regress atherosclerosis evaluated angioscopically determined markers
