title: Mortality due to diseases of the circulatory system among the elderly population in Brazilian Amazon: temporal and spatial analysis.
abstract: BACKGROUND
  Circulatory Diseases (CD) are the major cause of death among the elderly population in Brazilian Amazon.
  
  
  OBJECTIVE
  to analyze standardized mortality rates of diseases of the circulatory system (DCS), according to the main causes of death among the elderly, in microregions of the Brazilian Amazon, in the period of 1998 - 2007.
  
  
  METHODS
  ecological study of mortality rates distribution standardized by CD and corrected by deaths from poorly defined causes among the elderly (> 65 years of age) who lived in Brazilian Amazon in the period of 1998 - 2007. The analysis were carried out by the linear regression, trend, and spatial distribution of Kernel.
  
  
  RESULTS
  We verified an increasing trend in mortality by CD (β1 = 28.34 p = 0.01), due to the increasing trend in the States of Maranhão and Tocantins. The central region of Mato Grosso, Northern Tocantins, Eastern Pará and Southwestern Maranhão present hot spots with the highest mortality rates. Males present higher rates when compared to females all over the region; rates of mortality due to acute myocardial infarction and hypertensive disease present the same spatial standard of the CD group and the rates of cerebrovascular diseases present a different spatial distribution standard. Increment in mortality rates according to age was observed: the greater the age, the higher is mortality by CD.
  
  
  CONCLUSIONS
  The Brazilian Amazon presents an increasing trend with high rates of mortality by the circulatory diseases, and the geographic areas with the highest rates are around the Brazilian Amazon, in the states of Tocantins, Maranhão and Mato Grosso.
