Abstract
The results of prehospital diagnosis of myocardial infarction (MI) were studied in 1500 patients. The onset of MI was abdominal, gastralgic, and dyspeptic in 1.7, 1.3, and 0.4%, respectively. Abdominal MI differed from typical (anginal) MI in the relative predominance of old patients and women, late referrals to doctors, a high incidence of large and primary MI, worse prognosis. Hospital mortality in anginal and abdominal MI was 13.9 and 50.0% (p < 0.01), respectively. The rates of untimely diagnosis of anginal and abdominal MI were 13.4 and 25.0% and those of hyperdiagnosis were 19.9 and 31.8%, respectively. Prognosis in the hypodiagnosis of abdominal MI was worse than that in its hyperdiagnosis.
