Abstract
For the city of Rochester, Minnesota, USA, the coronary heart disease mortality rate showed approximately the same percentage decline as that for the USA during the period 1968-1978. The incidence rates of coronary heart disease (angina pectoris, myocardial infarction and sudden unexpected death) for the period 1950-1975 are based on 3080 cases. The incidence showed a decrease approximately 10 yr earlier than the decline in mortality and little change since that time. The age-adjusted case fatality rate for the incidence cases of myocardial infarction decreased from 18.7% in 1965-69 to 9.0% in 1970-75. The death rate during the 5 yr following the diagnosis of angina also decreased by almost 50%, and the myocardial infarction patients dismissed from the hospital showed little change in subsequent survivorship.
