[Mortality due to circulatory disorders and the evolution of family health in Brazil: an ecological study].

The scope of this study was to analyze deaths due to circulatory disorders in parallel with the evolution of the Family Health Strategy (FHS) in Brazil. It is an ecological and retrospective study based on the temporal evolution of the FHS and mortality rates due to circulatory disorders in Brazil. A description of the inhabitant x FHS coverage ratio and health indicators related to mortality due to circulatory disorders was carried out. Spearman's rank correlation coefficient test was used for the statistical association. There was a population increase of 15% in Brazil, evolution of 761% in the number of FHS units and 5% increase in mortality due to circulatory disorders. The population x FHS ratio rose from 52,838 (1998) to 7,084 (2006) people assisted by FHS units. North and northeast regions showed growth in mortality rates due to circulatory disorders and in 21 states (81%) there was a positive correlation between this mortality and FHS units (r: > 0.7; p < 0.01). Finally, the FHS is regarded as an important public health policy, which has achieved successful results in Brazil since its implementation. However, in general terms, its expansion has not influenced the reduction of mortality due to circulatory disorders, which is an indicator that has increased in the country.
