Vertraging bij de opname van hartinfarctpatienten

Timely treatment of patients with an evolving myocardial infarction improves the short and long term prognoses. Because of a wrong judgement of the situation by the patient, a significant other or by a general practitioner (GP), treatment may be delayed. To examine this delay 300 patients with myocardial infarction took part in a study between March 1990 and October 1991. After written consent was given, they were interviewed about the pre-hospital period. The significant others received a questionnaire about this period. Medical information was collected from the cardiologists. Fifty percent of all patients called for medical help within 30 minutes. The GP arrived within 11 minutes at the patient's place in 50% of all cases. However, in 50% of all cases the decision making of the GPs before the patient was sent to a hospital required more than 82 minutes. The ambulance arrived within 15 minutes at the patient's place in 90% of all cases. Stabilisation of the patient by the ambulance staff and transport to the hospital took slightly more time. Compared with earlier studies, the patient with a possible myocardial infarction calls for help sooner. Subsequently, in many cases it takes considerable time before the GP refers the patient to a hospital. Further research is needed to improve the diagnostic power of the GP.
