GEOGRAPHIC VARIATION IN DECLINING ISCHEMIC HEART DISEASE MORTALITY IN THE UNITED STATES, 1968–1978

Abstract

Despite the well known geographic pattern for heart disease mortality, studies of the decline in ischemic heart disease have not provided a comprehensive examination of its spatial component. In this study, the authors computed and mapped mean rates and per cent change in ischemic heart disease mortality for whites aged 35–74 years, for the period of the Eighth Revision (1968–1978) of the International Classification of Diseases. Visual evidence of clustering and markedly different spatial patterns were found for mean rate and per cent change among the state economic areas of the United States.
