Racial differences in mortality from cardiovascular disease in Atlanta, 1979-1985.
Mortality from cardiovascular disease (CVD) for the period 1979 to 1985 in the Atlanta metropolitan population was reviewed for racial differences. About 28% of the population was black in 1980. Of 22,585 deaths from hypertension, stroke, ischemic heart disease, and atherosclerosis, 78.7% occurred among whites and 21.3% among blacks. Overall, ischemic heart disease accounted for 47.7% of these four types of CVD deaths for both races and sexes. Age-specific and age-adjusted rates were compared. Among these four causes of death, blacks have the greatest excess of deaths from hypertension over whites for both males and females; the excesses were more than 200% when the rates were age-adjusted. The excess risk of death from hypertension occurred for all ages in blacks, with an excess of about 10 times in 30- to 49-year-olds. An excess risk from stroke also occurred in blacks below the age of 75; the risk reversed afterward. The age-specific mortality rates revealed an excess from ischemic heart disease only between the ages of 30 and 59 years and from atherosclerosis between 40 and 59 years of age for black men. This age-related crossover in females did not occur until the age of 75 years for deaths attributed to these causes. These data suggest that blacks were at highest risk for all four causes at younger age groups.
