Abstract
Abstract Background: Systemic Arterial Hypertension (SAH) represents the most relevant worsening factor and one of the major risk factors for cardiovascular diseases. Objectives: To analyze trends in the mortality rate associated with hypertensive diseases in Brazil from 2010 to 2014, for states as well as regions. Methods: An epidemiological study was performed from aggregate data obtained in populational strata. Cartographic data of the Brazilian territory in shapefile were provided by IBGE. Records of mortality associated with arterial hypertension were obtained in DATASUS, through notifications filtered by category I.10 of the International Classification of Diseases (ICD-10). The criterion of statistical significance was a two-tailed p-value < 0.05. Results: The increase in age was progressively associated with an increase in the mean number of deaths related to hypertensive diseases between the years 2010 and 2014. In the age groups between 50-59 years, 60-69 years, 70-79 years and 80 or more years, the mean and standard deviation for the mortality rate were, respectively: 15.11% (35.35); 24.14% (55.34); 35.07% (81.03) and 57.87% (139.08). The overall mortality rate per 10,000 inhabitants varied between the regions: north (1.25); northeast (2.69); center-west (2.06); southeast (2.48) and south (2.04). Conclusions: The mortality rate associated with hypertensive diseases was higher in the southeastern and northeastern states of Brazil, and remained stable between 2010 and 2014. Increased age and brown color were predictors of higher mortality.
Highlights
Cerebrovascular diseases have been classified among those with the greatest impact in terms of morbimortality.[1]
Systemic Arterial Hypertension (SAH) is characterized by increased blood pressure levels (≥ 140 and/or 90 mmHg), in which the clinical condition can be caused by several reasons and may be worsened by other risk factors, such as dyslipidemia, abdominal obesity, glucose intolerance, diabetes mellitus (DM), in addition to other modifiable factors, socioeconomic determinants and inadequate access to health care.[3,4]
According to IBGE’s population estimates for each year and state,[11] the global mortality rate related to hypertensive diseases was calculated per 10,000 inhabitants, between 2010 and 2014, which varied between regions: north (1.25); northeast (2.69); centerwest (2.06); southeast (2.48) and south (2.04)
Summary
Cerebrovascular diseases have been classified among those with the greatest impact in terms of morbimortality.[1] Among the major cardiovascular risk factors, systemic arterial hypertension (SAH) represents the most relevant worsening factor, requiring health actions in order to minimize the factors of impact that are determinant for the populations’ health.[2]. Several studies point to the influence of ethnic aspects in the emergence of hypertensive diseases.[5] Often it is difficult to dissociate the role represented by an ethnic group of the socioeconomic factors simultaneously active.[6] In Brazil, cerebrovascular mortality rates were higher in black people, followed by brown and white people.[7]. Systemic Arterial Hypertension (SAH) represents the most relevant worsening factor and one of the major risk factors for cardiovascular diseases. Increased age and brown color were predictors of higher mortality.
