On- and off-pump coronary artery bypass surgery. The heart surgeon should master both techniques

Recovery of linear and nonlinear heart rate dynamics after coronary artery bypass grafting surgery

“…This fact can be due to the effect of intrinsic characteristics of surgical approaches along the hospital stay, once the use of cardiopulmonary bypass has been recognized as the main cause of an extensive inflammatory reaction, global myocardial ischaemia and higher injury to the myocardium (Gomes, 2012;Rossaint et al, 2012), what may influence the HRV recovery. This fact can be due to the effect of intrinsic characteristics of surgical approaches along the hospital stay, once the use of cardiopulmonary bypass has been recognized as the main cause of an extensive inflammatory reaction, global myocardial ischaemia and higher injury to the myocardium (Gomes, 2012;Rossaint et al, 2012), what may influence the HRV recovery.…”

“…Confirming the hypothesis that both groups would present different trajectories of CA modulation, our results demonstrated that OPCAB group maintained with a better preserved CA, after the CR, compared to C-CABG, as indicated by higher indices of vagal (rMSSD and SD1) modulation. This fact can be due to the effect of intrinsic characteristics of surgical approaches along the hospital stay, once the use of cardiopulmonary bypass has been recognized as the main cause of an extensive inflammatory reaction, global myocardial ischaemia and higher injury to the myocardium (Gomes, 2012;Rossaint et al, 2012), what may influence the HRV recovery. Another possibility for our results is the greater impact on pulmonary function during C-CABG and respiratory rate, what could be an important influence on HRV (Montano et al, 2009).…”

“…Coronary artery bypass grafting (CABG) continues the mainstay of treatment for patients with advanced coronary artery disease (American College of Cardiology Foundation, 2012; Gomes, 2012). The choice to use cardiopulmonary bypass (on-pump versus off-pump) during CABG seems to elicit different recovery patterns and adverse event rates according to the patient's characteristics (Chawla et al, 2012;Gomes, 2012).…”

Predicting postoperative atrial fibrillation after myocardial revascularization without cardiopulmonary bypass: A retrospective cohort study

“…Among the reasons CPB is deleterious to the patient, it is known that by the activation of the complement system, mainly via the alternative pathway induced by blood contact with the circuit surface, the release of inflammatory mediators is triggered, leading to complications and organ dysfunction …”

Continuous Positive Airway Pressure During Exercise Improves Walking Time in Patients Undergoing Inpatient Cardiac Rehabilitation After Coronary Artery Bypass Graft Surgery

“…[1][2][3][4] Intrinsic surgical risk factors, such as thoracic manipulation, median sternotomy, cardiopulmonary bypass, general anesthesia, and pleural drain insertion, are responsible for postoperative respiratory disorder and lung function reduction. 5 , 6 Decreased pulmonary compliance, hypoxemia, and hypersecretion can also impact inpatient rehabilitation efforts, especially walking exercise, contributing to prolonged immobilization, greater rates of respiratory complications, and other adverse consequences.…”
