Influence of Dynamic Training on Hemodynamic, Neurohormonal Responses to Static Exercise and on Inflammatory Markers in Patients After Coronary Artery Bypass Grafting

Exercise Training for Patients After Coronary Artery Bypass Grafting Surgery

“…Adachi et al 23 assigned 34 patients with CABG to a 2-week exercise program, and cardiac output during exercise at 20 watt and at peak exercise significantly increased in the exercise group. In a recent study, Bilinska et al 30 reported that after 6 weeks of aerobic training at 70-80% of HR peak, the stroke volume and cardiac output were higher (by 13% and 15%, respectively) in trained patients compared with controls. Goodman et al 21 has explored central and peripheral adaptations after exercise training in 31 patients with CABG.…”

“…In order to measure hemodynamic and neurohormonal response to static exercise, Bilinska et al 30 randomized 120 male patients to either 6 weeks of aerobic training at a 70-80% of the HR peak or to a control group. After 3 months of training, handgrip-induced increases in HR, BP, and total peripheral resistance were lower, whereas stroke volume and cardiac output were higher (by 13% and 15%, respectively) in trained patients compared with controls.…”

Influence of aerobic training on neurohormonal and hemodynamic responses to head-up tilt test and on autonomic nervous activity at rest and after exercise in patients after bypass surgery

“…Details of the CPET protocol have been previously described [8]. Briefly, all patients underwent symptom-limited CPET according to a modified Bruce protocol, using a Schiller treadmill (Carrollton, USA) with gas exchange analysis (600USB CPX, ZAN Messgeräte GmbH, Germany).…”

“…During the test the following variables were monitored: HR during continuously recorded ECG, BP obtained with mercury sphygmomanometer, and stroke volume (SV), which was determined by impedance cardiography. As described previously, the system allows for the off-line, beat--to-beat evaluation of SV and HR [8][9][10]. Cardiac output (CO) was calculated as a product of SV and HR.…”

Exercise Is Beneficial: But How and Why?

“…1 These recommendations have been issued based on the evidence that regular moderate to vigorous aerobic exercise prevents the development of Type 2 diabetes mellitus, and in those with the disease, it improves it. In an extension of these recommendations, Bilińska et al 2 showed that short-term dynamic training caused significant improvement of hemodynamic and neurohormonal responses to handgrip, cardiovascular fitness and inflammatory state in the form of handgrip-induced increases in heart rate, blood pressure, and total peripheral resistance being lower, whereas stroke volume and cardiac output were higher with a concomitant increase in nitric oxide level and a lower increase in noradrenaline, which was observed in patients who had exercised compared with controls. These results suggest that exercise is anti-inflammatory in nature, as proposed previously.…”
