AimsIn western countries out-of-hospital ischaemic heart disease (IHD) deaths account for approximately 50-70% of all IHD deaths. The objective was to examine the trends in out-of-hospital IHD deaths in the Region of Skåne in southern Sweden, in different sex- and age-groups.MethodsAll 14,347 persons (range 24-110 years) in Skåne who died out-of-hospital between 1992 and 2003 from IHD (I410-I414; I20-I25) as the underlying cause of death. Subjects with previous admission for IHD since 1970 were excluded. Data were retrieved from the Swedish National Cause of Death and Patient Register. Age-standardized IHD mortality rates and trends were calculated using Poisson regression analysis.ResultsAge-standardized annual out-of-hospital IHD mortality rates from 1992-2003 decreased in men from 177±13 to 103±9/100,000 inhabitants (-4.7%; p<0.001) and in women from 142±11 to 96±9/100,000 (-2.7%; p<0.001). In men, the annual change in age-standardized IHD mortality rates were -5.3 % (p<0.001), -4.0 % (p<0.001) and -4.7 % (p<0.001), respectively, in the age groups 20-64 years, 65-74 years and ≥75 years. Corresponding figures in women were -4.4 % (p<0.001), -2.4 % (p=0.003) and -2.5 % (p<0.001). The proportion of IHD deaths occurring out-of-hospital was in these age groups 50%, 40% and 35% respectively.ConclusionsIn Skåne, out-of-hospital mortality in IHD deaths decreased significantly between 1992 and 2003. The decrease is more pronounced in men than women, and at the end of the study period in 2003, rates were almost equal. The proportion of IHD deaths occurring outside hospital was higher in younger people than in older people.
