The subject of this research is the anxiety of patients at different stages of genesis of myocardial infarction (MI). It is a proven fact that the high level of anxiety leads to reoccurrence and unfavorable course of disease both, in combination with other factors or regardless of them. However, the influence of separate aspects of anxiety into reoccurrence of MI remains insufficiently studied, which actualizes determination of the components of anxiety at different staged of emergence of this disease. The article presents a comparative analysis and description of the level of manifestation of various components of anxiety among the following empirical groups: 33 persons without myocardial infarction in past medical history, but in the group of risk by its genesis; 29 patients undergoing 2 to 5 days of hospital treatment for recovering after MI; 27 patients that have already received post-hospital therapy after MI. The observational group included 30 technically healthy persons. The following conclusions are formulated: 1) Anxiety components, such as asthenic, phobic, emotional discomfort are vivid among the patients who have survived MI, as well as persons in the risk group. However, an additional longitude research is required for proving the influence of anxiety into the genesis of myocardial infarction. 2) The currently conducted rehabilitation of MI patients reduces the overall level of situational anxiety, practically avoiding such its components that in the future can prompt recurrence of MI. 3) High level of anxiety is characteristic to all IM patients. The recommended programs for prevention and rehabilitation should be focused on long-term reduction of the level of personal anxiety, such as cognitive-behavioral psychotherapy.
