[Types of atherosclerotic changes in relation to the type of residual lumen and degree of narrowing in coronary arteries in ischemic heart disease].
510 segments of all three coronary arteries in 50 obduction cases of individuals suffering from ischemic (coronary) heart disease were microscopically examined. We examined the type of atherosclerotic change, the degree of narrowness of lumen artery and the type of residual lumen. In the group one of the narrowness of artery lumen 44 segments with fibrotic plaque were found, where concentric shape of lumen dominates. In the group two of the narrowness 176 segments were found. Most of them were with fibrotic plaque, but complicated atherosclerotic lesions were also present. According to the shape of residual lumen the concentric narrow shape dominates. In the group three of the narrowness of the lumen 191 segments were found; considering the type of atherosclerotic change complicated lesions were most common, while lipidic plaque was also present. An eccentric shape of residual lumen dominates this group. In the group four of the narrowness of lumen artery 99 segments were found; in this group we found fibrotic plaque and complicated atherosclerotic lesions. The most common finding of the residual lumen is the type of multiple lumen (channelled thrombi).
