To assess longitudinal trends in admissions, management, and inpatient mortality from acute myocardial infarction over 10 years.
Retrospective analysis based on the Nottingham heart attack register.
Two district general hospitals serving a defined urban and rural population.
All patients admitted with a confirmed acute myocardial infarction during 1982-4 and 1989-92 (excluding 1991, when data were not collected).
Numbers of patients, background characteristics, time from onset of symptoms to admission, ward of admission, treatment, and inpatient mortality.
Admissions with acute myocardial infarction increased from 719 cases in 1982 to 960 in 1992.
The mean age increased from 62.1 years to 66.6 years (P<0.001), the duration of stay fell from 8.7 days to 7.2 days (P<0.001), and the proportion of patients aged 75 years and over admitted to a coronary care unit increased significantly from 29.1% to 61.2%. A higher proportion of patients were admitted to hospital within 6 hours of onset of their symptoms in 1989-92 than in 1982-4, but 15% were still admitted after the time window for thrombolysis.
Use of bêta blockers increased threefold between 1982 and 1992, aspirin was used in over 70% of patients after 1989, and thrombolytic use increased 1.3-fold between 1989 and 1992.
Age and sex adjusted odds ratios for inpatient mortality remained unchanged over the study period. (...)
