title: [Early outcomes of instable angina].
abstract: Analysis of early outcomes of instable angina (IA) and the clarification of prognostic factors are no doubt very important in terms of rational organization of pre-hospital diagnostic and treatment. The aim of the study was to evaluate early outcomes of instable angina in residents of Tomsk within a period of 2 years. The subjects, 2,139 patients, were examined, and the diagnosis was confirmed in 1,477 (775%) of them, among whom there were 926 (62. 7%) men and 551 (37.3%) women. The number of subjects less than 60 years of age was equal to that more than 60, but the male subgroup was younger. The condition of 1,094 patients became stable, while in every fourth subject the outcome was acute myocardial infarction (MI) and acute coronary insufficiency. Large-focal MI was registered in 52.1% of patients; every fifth patient had transmurral MI, and every forth patient had small-focal MI. Large-focal MI was significantly more frequent in patients with variant III of IA, while small-focal MI was more frequent in patients with variant II, and transmurral -- in patients with a prolonged anginous attack (p < 0.05). The study demonstrates that patients suffering from variant III and variant IV of IA must be hospitalized and undergo treatment in a specialized hospital department.
