One of the ways to cut down the time interval from the moment a patient with acute myocardial infarction calls for aid until the time of his hospitalization is to increase the number of cardiological teams and also to define in detail the sequence of the appropriate actions of the controller and the emergency aid physician. As a result of the earlier arrival of specialized cardiologic teams at the place of the call, there has been a change in the structure of complications that such teams encounter; for example, cases of clinical death have occurred more frequently in the presence of the team. Subsequently, the number of cases of effective resuscitation rose from 5 in 1979 to 13 in 1982. The gradual reduction over four years of the duration of the prehospital stage in acute myocardial infarction has led to a decrease in both prehospital and hospital mortality. Interestingly, the prehospital mortality rate lowered gradually whereas the hospital mortality reduced significantly during the first year after which its parameters stabilized.
