Aims: Altered autonomic regulation precipitates cardiac arrhythmias and increases the risk of cardiac death. It is known that depression is related with worsen course of cardiovascular diseases. Cardiac autonomic modulation (CAM) and depression were not investigated in cardiac surgery pts in Lithuania. Therefore the aim of this study was to research CAM and depression levels in pts after coronary artery bypass grafting (CABG) and after valve surgery (VS). Methods: Cardiac autonomic regulation and depression was evaluated in 80 CABG (mean age 60.0±7.9yrs, 75.0% male) and 48 VS pts (mean age 54.2±13.2 yrs, 66.7% male) at 1.5 month after surgery.

Heart rate variability (HRV) data were measured using short-term ECG 5-minute recordings at rest. There were assessed indices - RR intervals (NN), standard deviation of mean RR intervals (SDNN) and sympathetic activity index (LF/HF). SCL-90R was applied for depression measure. Data were analysed with the SPSS for Windows version 13.0 package. Results: Increased depression levels were achieved by 44(55%) pts after CABG and 24(50%) pts after VS. CABG pts have demonstrated low NN scores (19(23.8%)), low SDNN (57(71.3%)), high LF/HF (64(80.0%)). [...].
