title: [The circadian rhythm dynamics of myocardial ischemia in patients with unstable stenocardia during one year of observation].
abstract: Dynamics of circadian rhythms of myocardial ischemia in patients with nonstable stenocardia within one year of observation was studied in 50 patients by means of Holter monitoring. By the second admission depending on the clinical course of the disease 4 groups of patients were singled out and their painful and nonpainful heart ischemia was assessed with 6-hour intervals. Comparison of results of painful arrhythmia during the first and repeat admission indicated that the diurnal dynamic and peaks of myocardial ischemia duration coincide as to time and direction. Nonpainful ischemia appears mainly during the night hours.
