[The frequency of behavioral type A among young myocardial infarct patients and their personality characteristics]. / Chastota povedencheskogo tipa A sredi bol'nykh infarktom miokarda molodogo vozrasta i ikh lichnostnye osobennosti.

Prevalence was studied of subjects presenting with behavioral type A among patients with myocardial infraction (MI) of young age, personality traits of the cases and lipid content in each of the groups identified. In spite of certain methodological difficulties existing in diagnosis of behavioral type of a personality we did not find type A to be predominant among young MI cases. It was subjects with psychosthenic traits, lowered tolerance to stresses that tended to prevail among MI patients of young age.

[The risk factors for the occurrence of a first and a recurrent myocardial infarct in young people]. / Faktory riska vozniknoveniia pervichnogo i povtornogo infarkta miokarda u lits molodogo vozrasta.

241 patients at the age of 22-41 with primary myocardial infarction (MI) and 51 patients who previously had recurrent MI have been examined. Rate of the principal generally accepted risk factors as well as blood group, professional, characterological, nutritional and other peculiarities being able to effect IM incidence were analyzed. The likelihood of primary and recurrent MI was found to be significantly connected with arterial hypertension (AH), hereditary burden, hypercholesteremia, stenocardia, astenoneurotic syndrome. The probability of myocardial infarction, especially of recurrent one, is increased in patients associating AH with stenocardia, hereditary burden with astenoneurotic syndrome, AH with hypercholesteremia, physical and nervous overstrain.

[The diagnosis of myocardial infarct at a young age in the prehospital stage]. / Diagnostika infarkta miokarda v molodom vozraste na dogospital'nom étape.

A study is presented of 103 patients with myocardial infarction (age: from 23 to 41 years) and 100 patients over 55 years-old. The younger patients showed rarely stenocardia in the preinfarction period, macrofocal lesions prevailed, more pronounced were leucocytosis, hyperenzymemia, hyperlipidemia and hyperthermia, rarely cardiogenic shock, cardiac asthma, pulmonary edema and complex rhythm disorders. Diagnostic errors were observed in 48.5% at the prehospital stage in the younger patients. The most frequent causes of errors were awareness of the physician for coronary pathology in the young, inadequate anamnesis screening and examination of patients.
