FALCON VILAU, Leonel; FERNANDEZ-BRITTO RODRIGUEZ, José E  e  CASTILLO HERRERA, José A. La lesión aterosclerótica coronaria en la muerte súbita: aplicación del sistema aterométrico. Rev Cubana Invest Bioméd [online]. 2000, vol.19, n.2, pp. 144-150. ISSN 1561-3011.

The main branches of the right, anterior descending and left circumflex coronary epicardial arteries of 237 patients that died from sudden death according to the selection criteria established by the World Health Organization and of 113 patients who died from non cardiovascular causes and without history of atherosclerotic risk factor, a group of low atherosclerotic level used as control, were studied. Both populations were the result of consecutive necropsies performed in persons over 15. The atherometric system was used for the morphological and morphometric characterization of the atherosclerotic lesion. The injured intimal surface was larger in the group of sudden death and its atherosclerotic profile was characterized by the strong predominance of the elevated lesions represented by the fibrous and severe plaques, which account for a higher index of obstruction and stenosis and a greater severity of the atherosclerotic process in this group. Fibrous and severe plaques showed a high signification, both isolated and as a whole, when the one-way variance analysis (ANOVA) and the multivariate analysis (MANOVA) were applied, respectively. This explained the quantitative differences found on comparing the mean values of the atherosclerotic lesions in the coronary arteries of the studied groups
