Insights
Heart failure (HF) mortality in Salvador, Brazil, significantly decreased by 34.4% between 1979 and 1995. Rates stabilized after 1992, indicating a positive public health trend for cardiovascular disease.
Area of Science:
- Cardiovascular Epidemiology
- Public Health Research
- Morbidity and Mortality Studies
Context:
- Heart failure (HF) represents a significant global health burden.
- Understanding regional mortality trends is crucial for targeted interventions.
- This study examines HF mortality in Salvador, Bahia, Brazil, over a 17-year period.
Purpose:
- To analyze the mortality trends associated with heart failure (HF) in Salvador, Bahia.
- To quantify changes in HF death rates from 1979 to 1995.
- To identify demographic patterns in HF mortality.
Summary:
- Mortality rates due to heart failure (HF) demonstrated a progressive decline from 1979 to 1992, with a subsequent stabilization until 1995.
- Overall gross mortality rate decreased by 34.4%, with similar reductions observed for both male and female populations.
- Age-adjusted rates indicated even greater relative reductions, highlighting a positive trend across various age groups.
Impact:
- The findings suggest successful public health strategies or improved clinical management of heart failure in the region.
- This epidemiological data can inform future healthcare planning and resource allocation for cardiovascular diseases.
- The study provides valuable insights into long-term trends of heart failure mortality in a major Brazilian metropolitan area.
Objective:
To assess mortality trend due to heart failure (HF) in Salvador--Bahia, from 1979 to 1995.
Methods:
HF was defined by notations from the 9th Review of International Disease Code (IDC9) 428.0, 428.1 and 428.9. HF death and population data (metropolitan area of Salvador) were obtained by means of Secretaria de Saúde da Bahia (Bahia State Health Secretariat) and Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics). Mortality rates (/100,000) were total or per gender and age, and gross or adapted per age (straight standardization).
Results:
Mortality rates due to HF had a progressive reduction in the period of time assessed, for both genders, especially up to 1992. From then and up to 1995, there was an apparent stabilization of the curves. Gross mortality rate went from 25.0/10(5), in 1979, to 16.4/10(5) inhabitants, in 1995 (a decrease of 34.4%). The reduction was 34.0% (23.3/10(5), in 1979, to 15.4/10(5) inhabitants, in 1995) for male sex and 35.2% (26.7/10(5), in 1979, to 17.3/10(5) inhabitants, in 1995), for female sex. The same trend took place in several age ranges, including the population > or = 40 years old, which has a greater risk for HF. After adaptation per age (standard population of 1979), it is observed that relative reductions in the rates were even greater.
Conclusion:
Mortality due to HF, in Salvador-Bahia, decreased from 1979 to 1992, becoming stable from then to 1995.
