Abstract

OBJECTIVE:

To improve time to treatment, the effects of acute myocardial infarction (AMI) symptoms on prehospital delay time (PDT) were investigated.

METHODS:

Patients with AMI completed a questionnaire on their AMI symptoms and their general knowledge of AMI symptoms.

RESULTS:

In total, 116 patients completed questionnaires. The mean PDT was 7.3 ± 2.4  h; the median PDT was 2.2 h. Each patient experienced a mean of 3.6 symptoms during their AMI. PDT was significantly shorter in the following groups: patients with chest compression pain/chest discomfort, profuse sweating or dyspnoea than in patients with other symptoms; patients presenting with typical rather than atypical symptoms; patients with pain scores >6 compared with scores ≤6; patients who were aware rather than unaware of AMI symptoms. Patients actually having AMI symptoms and patients being aware of AMI symptoms were inversely correlated with PDT. There was a linear relationship between pain scores and PDT.

CONCLUSION:

Public awareness of AMI symptoms should be enhanced, in order to shorten PDT and improve AMI survival rates.
