title: [Pre-hospital factors of in-hospital mortality of myocardial infarction].
abstract: The time of referral for medical care, results of prehospital diagnosis and hospital myocardial infarction (MI) lethality were studied in 1138 inpatients. Early referral (within 6 hours of the disease onset) was in 61.9% cases. Hypodiagnosis was registered in 15.6%. Hospital lethality in MI was 14.7%. By age groups: 45-59 years--4.9%, 60-74 years--13.0%, 75 years and older--21.1% (p < 0.01); in women--12.1%, in men 16.0% (p < 0.05); in first and second MI--10.3 and 19.2%, respectively (p < 0.05), in typical and atypical MI--13.9 and 16.6% (p < 0.05), respectively. In early and late referral in patients with macrofocal MI hospital lethality reached 19.3 and 11.7% (p < 0.05), respectively. In early referral hypodiagnosis of macrofocal MI did not increase lethality. In late referral lethality was higher (p < 0.05) in the presence of hypodiagnosis (11.7%).
