Mortality Trends from Cardiovascular Diseases in the State of Bahia, Brazil, between 2000 and 2015

Abstract

Background: Mortality from cardiovascular diseases has reduced in Brazil in recent decades, but this phenomenon is not clear in the northeast region of the country. Objectives: To describe the mortality trends from cardiovascular disease in Bahia from 2000-2015, in total population and by sex and age groups, and by specific causes (ischemic heart disease, cerebrovascular diseases, rheumatic heart disease and heart failure). Methods: This was a time series study. Data were obtained from SIM-DATASUS and IBGE, and the 10th revision of the ICD used for disease classification. Mortality rates (per 100,000 inhabitants) were calculated from total cardiovascular disease and specific causes, by sex and age groups. Direct standardization was used to adjust for age, using the population of 2010 as reference. Linear regression models estimated percentage variation. The significance level of 5% was adopted. Results: In Bahia, crude mortality rates from cardiovascular disease increased in the period; however, after standardization by age, mortality rates became stable for the total and female populations, with a slight reduction for the male population. An increase in mortality rates from cardiovascular disease was found in the elderly groups. For ischemic heart disease, a progressive increase in adjusted mortality rates was observed: 43%, 24% and 29% for the total, male, and female population, respectively. There was a progressive reduction in crude and age standardized mortality rates from heart failure in all groups, a modest reduction in age-adjusted mortality rates from cerebrovascular diseases, and a slight reduction in age-standardized mortality rate from rheumatic heart disease, especially in the subgroup<40 years. Conclusions: Mortality from cardiovascular disease in Bahia did not follow the decreasing trend of other Brazilian states, especially in relation to ischemic heart disease, which showed an increase in mortality rates.
