Abstract
According to the official vital statistics, altogether 10910 deaths from ischaemic heart disease (IHD) occurred in persons resident in Helsinki during the 10-year period 1959-68. A significant increase was found in the incidence of IHD deaths in both sexes even though changes in the structure of the population were taken into account. The increase in the age-dependent incidence of IHD deaths was most conspicuous at middle age in both sexes and in young males. Altogether 3044 IHD deaths occurring unwitnessed or within 24 hours of the onset of the fatal attack were autopsied medico-legally during the 10-year period of the study. The medico-legally autopsied cases obviously represented a high proportion of sudden IHD deaths occurring outside hospitals in Helsinki. A clear male preponderance was found in the autopsy material as compared with all IHD deaths. The prevalence of cases of acute myocardial infarction varied in different years from 27 to 49 percent at medico-legal autopsies. No significant change occurred during the 10-year period in the distribution of the medico-legally autopsied IHD deaths into social groups, in the suddenness or place of death. The home was the most common place of death. From 1963 onwards the patients dying from an ischaemic heart attack during transportation to hospital or in an outpatient department constituted 6-7 percent of all annual IHD deaths.
