| Abstract: | Casts were produced of the arterial networks of 25 human hearts obtained at autopsy from subjects who were not diagnosed as having cardiovascular disease. Many casts showed imprints of atherosclerotic plaques, remnants of calcified masses, and fine vascular meshes near the lumen of the major coronary arteries. Of 25 casts produced, 14 contained one or more of these anomalies, seven contained vascular meshes, and five of these related to imprints and/or calcified masses. Analysis of these findings in the context of atherosclerosis, intramural hemorrhage, and vascular spasm, suggests possible relationships between them. The findings support the hypothesis that neovasculature in the walls of coronary arteries may play a role in the pathogenesis of vascular disease and malfunction. |
