Key result
The delay between symptom onset and calling for an ambulance was significantly longer for female patients (P=0.0001) and those over 65 years of age (P=0.0001).

What baseline characteristics are associated with time delays in pre-hospital and hospital thrombolytic treatment in patients with suspected acute myocardial infarction?
Women and older patients experience longer delays between symptom onset and calling for an ambulance in suspected acute myocardial infarction, highlighting target populations for educational interventions.
Leizorovicz et al. (1997) conducted an RCT in suspected acute myocardial infarction (n=5,469). Pre-hospital thrombolytic treatment vs. Hospital thrombolytic treatment was evaluated on Components of the interval between symptom onset and treatment. The delay between symptom onset and calling for an ambulance was significantly longer for female patients (P=0.0001) and those over 65 years of age (P=0.0001).
