[Prevention of coronary atherosclerosis. II: Topography and morphology of "protruding" lesions. Epidemiologic, diagnostic and therapeutic implications].
Topographic and morphologic aspects of coronary atherosclerotic "protruding" lesions were investigated in 119 accidental deaths in males living in Mexico City. Morphology and topography varied according to the arterial trunk studied and age. Left anterior descending and circumflex lesions were almost always confined to the initial 5 cms and if a lesion was present after the 3rd cm there was always a proximal lesion. Right coronary lesions occasionally were found distally even in the absence of proximal lesions. Third decade lesions were usually not calcified. Stenosis if present was rarely multivascular. Some fourth decade lesions were calcified; plurivascular stenosis was present in some cases. Fifth decade lesions show sequential stenotic lesions in the same vessel; calcium and plurivascular stenosis were often observed. However the features observed in the 3rd decade could be observed in the older subjects. Reference is made to lesions which are found in both the left main trunk and the left anterior descending. Epidemiological and clinical applications related with preventive programs are mentioned.
