[Factors delaying therapy in myocardial infarct].

The timelag from onset of myocardial infarction to beginning of treatment is significantly correlated with prognosis, especially since introduction of thrombolytic therapy. Based on the last case of 967 Austrian physicians (general practitioners and internists, working in an office or in a hospital) we investigated possible factors delaying the beginning of treatment. On the average it took 111 minutes from onset of symptoms until the patient contacted physicians working in offices. The overall mean from onset of symptoms to hospital admission was 136 minutes. Within the hospital almost no delay was reported. Main factors for delay were repression or suppression and misinterpretation of symptoms. Thus, the biggest potential for an early onset of treatment lies within the patients response to onset of symptoms. Measures improving knowledge about mechanisms of the disease of known or possible coronary heart disease patients are most important. Side-effects, such as over-critical or demanding patients should be avoided. In any case they should not distract from the importance of measures improving patients response.
