Abstract
Background. It is known that after coronary artery bypass graft surgery (CABG) heart rate variability (HRV) becomes significantly decreased with a gradual recovery in a few months after surgery. However, literature data about the impact of the off-pump CABG on postoperative HRV are not complete. Therefore, the aim of this study was to analyze postoperative value of HRV in CABG patients operated on with off-pump versus on-pump coronary surgery. Methods. This study included 206 consecutive patients who underwent CABG. Sixty six patients (32%) were operated on off-pump while 140 patients (68%) were operated on using the machine for extracorporal circulation. HRV was analyzed from 24-hours Holter electrocardiogram recordings. Results. No significant differences in postoperative values of HRV variables were found between off-pump versus on-pump CABG patients (Mean RR interval 885 ± 106 versus 879 ± 125 ms, standard deviation of all normal R-R intervals 107 ± 30 versus 105 ± 34 ms, NS, total power 2298 ± 2472 versus 2156 ± 1913 ms2, NS). Conclusions. The results of the study showed that there are no differences in HRV few months after surgery between patients operated on with off-pump versus on-pump CABG.
Highlights
Today fewer patients undergo coronary artery bypass grafting (CABG) because of modern way of treating coronary artery disease, especially with percutaneous coronary intervention (PCI) procedures
During the stationary cardiac rehabilitation, the following values of heart rate variability (HRV) variables were measured in off-pump versus on-pump coronary artery bypass graft surgery (CABG) patients (Table 2)
There were no significant differences in any postoperative value of HRV variables between off-pump versus on-pump CABG patients
