[Dynamics of parameters of heart rate variability in patients with ischemic heart disease after direct myocardial revascularization].
OBJECTIVE
To study dynamics of parameters of heart rate variability (HRV) in patients with ischemic heart disease after direct myocardial revascularization.


METHODS
Electrocardiography (ECG), 24 hour Holter ECG with spectral and temporal analysis of 24-hour HRV, as well as echocardiography (Echo) and stress-Echo were carried out in 24 patients with ischemic heart disease before, in 2-4 weeks and 2 months after surgery. Healthy persons of the same age (n=20) were used as controls.


RESULTS
Prior to operation HRV in all patients was lower than in controls. In 2-4 weeks after coronary artery bypass grafting (CABG) further lowering of HRV parameters occurred. In 2 months after CABG HRV parameters in patients without complications were similar to preoperative values but remained lower than in controls.
