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 ms(2), 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.

Heparin is an anticoagulant used invariably in all cardiac surgery. Heparin dosing and its reversal were determined by monitoring activated clotting time (ACT). Intermittent heparin dosing after initial bolus dose is widely practiced to maintain ACT level 200-300 seconds in Off-pump coronary artery bypass surgery (OPCAB).

Objective: This study compared the clinical efficacy of off-pump coronary artery bypass grafting (OPCAB) with percutaneous coronary intervention (PCI) in the treatment of left main coronary artery and/or triple-vessel disease (LM and/or TVD).
Methods: We retrospectively enrolled 1484 consecutive patients with LM and/or TVD in Shanxi Cardiovascular Hospital from January 2015 to December 2022 and divided them into the OPCAB group (n = 583) and the PCI group (with second-generation drug-eluting stents) (n = 901). Propensity score matching was used for 316 equally matched pairs of patients in the groups.

Coronary artery bypass grafting (CABG) using cardiopulmonary bypass (CPB) causes a systemic inflammatory response that can worsen patient outcomes. Off-pump surgery has been associated with a reduced inflammatory response. The precise mechanisms and the role of extracellular vesicles (EVs) in this context are not fully understood.
