To assess mortality trend due to heart failure (HF) in Salvador--Bahia, from 1979 to 1995.
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).
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.
Mortality due to HF, in Salvador-Bahia, decreased from 1979 to 1992, becoming stable from then to 1995.
评估1979年至1995年期间巴西巴伊亚州萨尔瓦多市因心力衰竭（HF）导致的死亡率趋势。
HF由国际疾病分类第九版（IDC9）编码428.0、428.1和428.9定义。HF死亡数据和人口数据（萨尔瓦多市大都市区）通过巴伊亚州卫生秘书处（Bahia State Health Secretariat）和巴西地理与统计研究所（Brazilian Institute of Geography and Statistics）获取。死亡率（每10万人）按总体、性别和年龄划分，以及按年龄进行粗死亡率或调整死亡率（直接标准化）。
在评估期间，男女因HF导致的死亡率均呈逐步下降趋势，尤其是到1992年。从那时起到1995年，曲线明显趋于稳定。粗死亡率从1979年的25.0/10万降至1995年的16.4/10万居民（下降了34.4%）。男性死亡率下降了34.0%（从1979年的23.3/10万降至1995年的15.4/10万居民），女性死亡率下降了35.2%（从1979年的26.7/10万降至1995年的17.3/10万居民）。在几个年龄组中都出现了相同的趋势，包括年龄≥40岁的人群，该人群患HF的风险更高。按年龄调整后（以1979年的标准人口为基准），观察到死亡率的相对下降幅度更大。
1979年至1992年期间，巴西巴伊亚州萨尔瓦多市因HF导致的死亡率下降，从那时起到1995年保持稳定。
