Supporting Information Table S1 provides the main demographic
and clinical characteristics of the study participants and
proximal presence of bystander factors including way of transport,
distance from hospital, presence of bystander and medication
received during the incident.
Patients were predominantly
men (81%). The median age of the study population was
64 years (IR: 20).
The majority of the patients were Greek (97%)
and married (72%).
Only 9% of the patients were university
graduates and 42% were main city residents. Hypertension,
smoking and hypercholesterolaemia were listed among the main
risk factors for AMI (62, 62 and 55%, respectively) whereas the

The majority of patients (74%) reported mediumscale
pain (scale 6–8) whereas only 12% of the patients reported
severe pain (scale 9–10). Thirteen per cent of the patients arrived
at the hospital within the first 2 h of the symptoms onset,
whereas the median time of arrival at the hospital was 8 h (IR: 8).
Only 119 patients (25%) called an ambulance, whereas 358
patients (75%) used another way of transport. The incident
occurred in a place less than 10 km away from a hospital for the
majority of patients (63%). Additionally, 65% of them mentioned
a bystander during the event. After the first symptoms
initiated, 96 patients (20%) received medication.
The majority of
these patients (n = 51) received nitrates sublingually, whereas 43
