What relevance has the atherosclerotic lesions occurrence had in the coronary vascular sector of the dead by sudden cardiac death in the communities of Arroyo Naranjo? To describe the behavior of the atherosclerotic lesions in the vascular coronary sector of the suddenly dead people in the communities of Arroyo Naranjo in the period 2000-2004. A descriptive study was carried out with 5098 dead of natural causes diagnosed in the University Hospital "Julio Trigo López". Based on the criteria defined by the (WHO) about SCD, 474 patients were included in the research. A Primary Data Recollection Model (PDRM) was drafted. Among the variables to be studied, Atherosclerosis was considered, an etiological factor described by medical literature as responsible in more than the 90% of the deaths that occur under unpredictable circumstances. To document this factor we went to the findings in the necropsy studies of the patients that underwent this procedure, evidencing extense, irregular and severe atherosclerotic lesions in the coronary vascular tree responsible of the unexpected death. Information gathered from the necropsies protocols given by the Pathological Anatomy Department of the University Hospital "Julio Trigo López", in Ciudad de la Habana, Cuba. Atherosclerosis was documented in the 75.5% of the cases, in the 77.9% male dead, representing more than the 70% of the cases in those older than 45 years. The presence of an Acute Myocardial Infarct and the disorders in the cardiac rhythm were the consequent diseases of atherosclerosis, which were relevant in our study with the 58.4% and 20.7% respectively.Atherosclerosis represents the principal etiological factor for the Coronary Arterial Disease (CAD) and in consequence, for Sudden Death. The variety of the lesions with the prevalence of the complicated scales (serious) in the left front descendant artery; characterize the vascular profile of the dead by Sudden Death of cardiac origin in our study.
