This study, undertaken in the Bas-Rhin area of France by the MONICA Register, presents the evaluation of the procedures followed for 323 subjects under 65 years old suffering from an acute myocardial infarction and subsequently hospitalized for this reason. We observe that 87.5% of the patients first consult a private practitioner -- for the most part a non specialist -- while 9% first contact a mobile coronary unit. 3.5% of patients go directly to hospital. Concerning delays in hospitalization, 35% of patients more than 6 hours to consult a doctor, while the median time between the onset of symptoms and the first call for medical aid is 2 hours. The median delay between the onset of symptoms and arrival at hospital is 5hrs 45 min., 28% of the subjects requiring more than 24 hours to be hospitalized.
