[Premature mortality from heart diseases in Brazil. A comparison with other countries]
1Hospital das Clínicas--FMUSP.
Insights
Brazilian cities experienced high heart disease premature death rates between 1984-87, particularly among women. These mortality patterns were comparable to or exceeded those in Europe and the United States.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Chronic diseases are the leading cause of mortality in Brazilian metropolitan areas.
- Circulatory diseases represent the primary category of chronic diseases.
- Premature mortality from heart disease is a significant public health concern.
Purpose of the Study:
- To compare premature heart disease mortality rates in Brazil with international data.
- To analyze trends in heart disease mortality between 1984 and 1987.
Main Methods:
- Utilized official mortality statistics from eight major Brazilian metropolitan areas.
- Analyzed deaths attributed to coronary heart disease and broader heart diseases (ischemic heart disease, heart failure, hypertension).
- Population data derived from the 1980 and 1991 Brazilian National Censuses, with interpolation for interim years.
Main Results:
- Brazilian men exhibited medium heart disease mortality rates, ranking among countries like Hungary and Finland.
- Brazilian women displayed high heart disease mortality rates, ranking among the top globally, with cities like Rio de Janeiro and Curitiba showing notable rates.
- Coronary heart disease mortality patterns mirrored those of overall heart diseases for both men and women.
Conclusions:
- Brazilian cities demonstrated high age-adjusted mortality rates for heart diseases (ages 45-64) during 1984-87.
- These rates were similar to or higher than those observed in Europe and the United States.
- Women in Brazilian cities were particularly affected by high heart disease mortality.
Purpose:
Chronic diseases have been the main cause of mortality in the Brazilian metropolitan areas since 1960. Circulatory diseases are the main causes of chronic diseases. The aim was to compare the heart disease related premature deaths in Brazil with other countries in 1984-87.
Methods:
We studied the deaths from the official mortality statistics from eight metropolitan areas with good assurance of information: Belém, Recife, Salvador, Belo Horizonte, Rio de Janeiro, São Paulo, Curitiba, Porto Alegre. Death causes analyzed were coronary heart disease (410-414); and heart diseases [ischemic heart disease (410-414) plus heart failure (428) plus, hypertension (401-404)]. The population was determined from the National Brazilian Census in 1980 and 1991, in other years it was determined by linear interpolation.
Results:
The international comparison showed that: a) heart disease mortality rates for Brazilian men was ranked (Hungary, Rio de Janeiro, Finland, Porto Alegre and Poland) in the medium and among women (Rio de Janeiro, Curitiba, Hungary, Porto Alegre and England and Wales) in the top; b) coronary heart diseases showed the same pattern of heart diseases for men (Finland, Hungary, England and Wales, Porto Alegre, Rio de Janeiro) and for women (Rio de Janeiro, Curitiba, Hungary, Porto Alegre, England and Wales).
Conclusions:
The international comparison of age-adjusted mortality rates in the age strata 45-years-old to 64-years-old during the period 1984-87 showed that Brazilian cities had a high mortality pattern of heart diseases, similar or greater than Europe or United States, mainly among women.
