Abstract
The paper presents the results of prehospital diagnosis of myocardial infarction (MI) in 1500 patients. MI was atypical in 28.6% patients. Most frequently occurred: MI with atypical pain syndrome (11.7%), asthmatic MI (7.0%), arrhythmic MI (2.9%), asymptomatic (3.3%). Late diagnosis of typical (anginal) and atypical MI was 13.4 and 21.2%. Hyperdiagnosis took place in 19.9 and 45.8% (p < 0.01), respectively. Reduction of hypo- and rise in hyperdiagnosis occurrence in 1992-1996 occurred due to atypical variants. This is explained by higher medical skills of the physicians and better knowledge about MI atypicity.
