The action promoting fibrinolytic treatment of myocardial infarction and questionnaire-based follow up of the results was carried out over a four million people area. 5262 questionnaires, in which physicians answered a number of questions, were received. The poll revealed that 79% of patients received fibrinolytic treatment. The authors estimate the overall percent of patients, treated in hospital wards, at about 27.7%. The mortality rate in the group of patients, who received streptokinase, was 8.61% and in the group of patients, who did not receive the treatment, was 16.28%. The signs of reperfusion were present in 60.38% of patients. The authors conclude that the increase in the number of patients administered fibrinolytic treatment should be aimed, and the results obtained in this group of patients come close to published data. Exercise tests are performed in too small number of myocardial infarction patients and only little proportion of them undergoes further coronary angiography.
