Abstract
AIM: To assess results of prehospital diagnosis of myocardial infarction (MI) in patients of different age and gender. MATERIALS AND METHODS: The results are available of prehospital diagnosis of MI in 1500 patients in 1992-1996. 49.5 and 32.3% patients (females and males, respectively) were over 75 years of age. In this group of patients MI was atypical and repeated in 34.4 and 60.6% of cases. Atypicity was more frequent in females. RESULTS: No statistically significant differences were found in frequency of diagnostic errors in different demographic groups of patients. For 5 years there was a trend to hyperdiagnosis of MI, especially in young patients and males. Late diagnosis occurred more rarely in both males and females. CONCLUSION: Clinical features of MI in elderly patients and females are essential for the number of diagnostic errors especially in high medical qualification.
