Implication
CHD declines in Sweden 1975-1994 support prevention gains; leaves open persistence and generalizability today.
Key Points
- To assess 20-year trends in attack rate, incidence of non-fatal myocardial infarction, and coronary heart disease mortality in individuals aged 64 years and younger.
- Analyzed longitudinal surveillance data from the Göteborg myocardial infarction register covering the years 1975 through 1994.
- Tracked attack rates, non-fatal incidence, 28-day case fatality, and treatment interventions using standardized diagnostic criteria across consistent age strata.
- Attack rate and incidence decreased significantly by 2.1% to 3.9% per year across most age groups, remaining 3-5 times higher in men than in women.
- Coronary heart disease mortality declined by 2.0% to 6.8% per year, with 28-day case fatality declining significantly primarily in the oldest male group (aged 55-64).
- In-hospital administration of intravenous beta-blockers, nitroglycerin, and thrombolytics rose over time, while the majority of fatal events continued to occur pre-hospital in individuals without diagnosed heart disease.
