The number of deaths by cardiovascular diseases is one of most important health problems in the present because they represent the leading cause of death worldwide, including Brazil (somewhere around 30% in recent years, according to data from the Mortality Information System - SIM/DATASUS). However, mortality from this cause begins to show a declining trend in many countries in parallel to the stage that these are in the process of demographic transition and/or epidemiological. Thus, the main objective of this dissertation is to check and analyze the spatial and temporal variations of deaths from cardiovascular disease in the adult population (over 30 years), by sex, in Brazilian micro-regions, in the 1996-2010 period. To this end, data from the Mortality Information System were used - SIM/DATASUS, Chapter IX, of the Tenth Revision of the International Classification of Diseases. The data analysis involved different steps. First, the quality of the data was checked and the under registration of deaths corrected. Second, we apply two alternative methods to improve estimates of mortality by age, namely, standardization and smoothing via Bayesian statistics. Based on these estimates was possible to perform an exercise of decomposition to verify the effects of rate and age structure of the observed mortality differential and, thereafter spatial analysis methods to discuss the evolution of mortality from cardiovascular disease in the country. The results suggest that, given the correction of under registration, there is a decrease in the rates of deaths from cardiovascular disease with the passing of years. Moreover, the spatial distribution, in general, shows changes over the study period. While in the initial years, the first five years, the highest rates of deaths from cardiovascular disease tend to be concentrated in the micro-regions of South and Southeast regions of Brazil, notably the more developed regions of the country, in the final years the highest rates are presented in micro-regions of the North and Northeast regions, especially the last. These findings indicate that the Brazilian epidemiological transition is not uniform between and even within their own states. Moreover, these results enable policy makers better know the reality of their regions and population and thus to design health policies that aim to improve the quality of life.
