Mortality from ischemic heart disease in Iceland, 1951-1985.

The objective of this study was to evaluate mortality rates from ischemic heart disease among Icelanders during the period of 1951 to 1985. In some developed countries, the number of deaths from ischemic heart disease declined markedly in this time period, and it is interesting to study whether the same has occurred in Iceland. The study was based on information obtained from the Statistical Bureau of Iceland, which keeps records of deaths based on death certificates as well as other population records. Nonparametric tests were used to correlate death rates and calendar years. Rates per 100,000 were calculated and plotted. The results indicated that the mortality rates from ischemic heart disease among Icelanders have not yet peaked.
