[Acute myocardial infarction and thrombolysis: analysis of the delay in arrival at the hospital].

Since the duration of precordial pain plays a key role in the indication for thrombolytic treatment in acute myocardial infarction, a retrospective study was made of the last 200 infarctions at Monthey Hospital with particular reference to the factors influencing this duration (distance, type of transport, prior intervention by a physician, loss of time in hospital). These factors were compared with other studies, and ways of influencing the time factor are proposed.
