UNSTABLE ANGINA - LONG-TERM FOLLOW-UP BY HOLTER MONITORING FINDINGS

The choice of treatment of patients with unstable angina is one of the most important problems in cardiology. Establishment of its tactics i s necessary both in hospital and in posthospital periods. 24-hour Holt er monitoring is a safe and informative method which makes it possible to objectivize the state in such category of patients. In order to st udy the structure of ischemia and arrhythmias this approach was used i n 50 patients with unstable angina at the first admission twice and al so twice within the first year of follow-up. It was showen that stabil ization which was achieved during the first hospitalization was retain ed in 58.2% during 1 year. In other cases increases of frequency, dura tion and significance of ischemia were observed. In the global structu re of myocardial ischemia, silent ischemia composed 56-65%.
