Stroke and ischemic heart disease mortality trends in Brazil from 1979 to 1996.

Stroke and ischemic heart disease (IHD) mortality rates were analyzed in Brazilian subjects older than 30 years of age from 1979 to 1996. Population estimates were based on census surveys. Mortality data were obtained from the Ministry of Health. For stroke, the age-adjusted death rate (ADR) dropped from 200 to 164 and from 168 to 130 deaths/100,000 population in men and women, respectively (p < 0.001), in the interval study. For IHD, the ADR dropped from 194 to 164 and from 119 to 105 deaths/100,000 population in men and women, respectively (p < 0.001), in the same time period. Mortality from stroke and IHD combined was greater in men for all age groups (p < 0.001). Stroke was the most frequent cause of death in both women and men except for men aged between 40 and 69 years, in whom IHD was more common. Stroke and IHD were the main causes of death in the Brazilian population. Copyright 2003 S. Karger AG, Basel
