[The effects of various factors on long-term outcomes of non-stable stenocardia].

The article presents the results of one-year observation of 472 patients who experienced non-stable stenocardia in 2003-2004. During this period, exacerbation of coronary artery disease with or without acute coronary catastrophe was noted in every third patient. Thirty-three cases of acute coronary pathology were registered. Year lethality was 27.3%, with acute myocardial infarction as the leading cause of death. By step-wise diagnostic regression method it was proved that old myocardial infarction was the only factors that had a significant negative effect on the long-term prognosis of non-stable stenocardia.
