Background : Trends in the incidence of acute myocardial infarction (MI) that are based on admissions to hospital would be misleading if the proportion of non‐fatal infarctions treated at home changed over time. Aim : To estimate trends in the management at home of cases of non‐fatal AM1 in Perth between 1984 and 1993 in order to determine if the number of such cases has remained consistently small and can be neglected in studies of the incidence of AMI. Methods : In 1989, 251 general practitioners in Perth responded to a postal questionnaire asking about management of cases of AM1 at home in the preceding 12 months. In 1993, 288 general practitioners and 174 physicians responded to the same questionnaire. Results : We estimate that 1.5% of all patients less than 65 years of age diagnosed with non‐fatal AM1 were managed at home in 1989. The corresponding figure for 1993 was 4.1%. A previous study in Perth in 1984 found that 3.9% of cases of non‐fatal AM1 in patients less than 65 years of age were managed at home. Conclusion : The management at home of cases of non‐fatal AM1 in people of working age in Perth has remained at a negligible level from 1984 to 1993. Thus a register based on admissions to hospital for AM1 will accurately reflect trends in AM1 in people of working age.
