Trends in the risk of mortality due to cardiovascular diseases in five Brazilian geographic regions from 1979 to 1996

Abstract

Objective -

Mortalidade por doenças do aparelho circulatório no município de Ribeirão Preto - SP, de 1980 a 2004

“…In Ribeirão Preto, death proportions due to the non-defined causes did not exceed 6% along the series under study, which was also lower than the findings by Souza et al 10 in a study conducted in the Southeastern Region (11%) between 1979 and 1996. In the period under study, proportional mortality estimates due to non-defined causes of death in Ribeirão Preto revealed that the observed trends for DCS mortality rates were not impacted by the number of deaths from unknown causes-which emphasizes the internal validity of the present study.…”

“…In the 80 years-old and older some of the cases showed higher magnitude of mortality rates among females when compared to males. In the Northern Brazilian Region and in Pará State, Souza et al 10 and Mansur et al 17 , respectively, have reported similar results with higher mortality rates among females when compared to males as of 70 years of age and from then on.…”

“…In a study conducted by Souza et al 10 in the period between 1979 and 1996, the authors observed that mortality rates due to DCS showed different trends in the five geographic macro-regions in Brazil. Results pointed towards a decline trend as of 30 years of age in the Southern, Southeastern and Northern Regions, although the opposite trend was observed for the Northeastern and Central-Western Regions.…”

“…The major determinants for such decline cannot, therefore, be pinned down. Those hypotheses include better access to medical assistance by the population in general, scientific and technological advance in DCS diagnosis, and better understanding of the pathophysiology of these conditions [6][7][8]10,17,19 . The lack of data for the development of time series to assess DCS potential risk or protection factors, as well as of analytical epidemiologic studies to test associations between those factors and DCS mortality rates do limit more consistent explanation related to those decline in Brazil.…”

Demographic and clinical characteristics of hypertensive patients in the internal medicine outpatient clinic of a university hospital in Rio de Janeiro

“…1,2,3 Arterial hypertension is the most frequent treatable cardiovascular risk factor for death, 2,3,4 with prevalence ranging from 10 to 44% in different studies and countries. [4][5][6][7][8][9][10] Without symptoms in its initial stage, hypertension is generally diagnosed only when complications appear, thus causing significant losses in quality of life and increasing mortality rates.…”
