Key result
Patients with a recent acute myocardial infarction were more likely to state they would call the alarm number for chest pain compared to the general public (86% vs 75%, p=0.012), though overall knowledge of typical AMI symptoms was similar.

AMI patients do not possess better knowledge of heart attack symptoms than the general public, highlighting the need for improved, individualized patient education to reduce pre-hospital delay.

Similar symptom knowledge in recent AMI patients and public warrants caution against assuming prior education suffices; leaves open whether targeted programs shorten prehospital delay.
Background: Patients with acute myocardial infarction often have long decision times before seeking medical care. The decision time is influenced by knowledge of AMI-symptoms, psychological factors and the response of people near the patient to the symptoms. Aim: To investigate and compare the knowledge of AMI, intended actions in response to AMI-symptoms and attitudes toward seeking medical care of patients and the general public. Method: This was a multicentre study with descriptive and comparative design, using questionnaires as an instrument. The population consisted of AMI-patients and representatives of the general public. Results: There was good knowledge about typical AMI-symptoms among the participants. The majority thought an AMI always starts suddenly. Patients did not know more about the time-dependency of treatment outcome than the general public. A greater proportion of the general public would contact an additional person before consulting medical professionals. Conclusions: Patients had no better knowledge about AMI than the general public, but would more commonly act appropriately in case of AMI-symptoms.

Henriksson et al. (2012) conducted a cross-sectional in Acute Myocardial Infarction (AMI) (n=664). Prior experience of Acute Myocardial Infarction vs. General public (no prior AMI) was evaluated on Intention to call the alarm number if experiencing own chest pain (p=0.012). Patients with a recent acute myocardial infarction were more likely to state they would call the alarm number for chest pain compared to the general public (86% vs 75%, p=0.012), though overall knowledge of typical AMI symptoms was similar.
