Abstract：Objective To explore the guiding role of cardiopulmonary exercise testing(CPET)in guiding perioperative aerobic exercise rehabilitation training of patients with coronary artery bypass grafting(CABG)and its effect on cardiopulmonary function.Methods A total of 148 CABG patients in the hospital were selected and randomly divided into observation group and control group,74 cases in each group.CPET was used to assess cardiopulmonary function.Both groups received routine care and standard treatment post-CABG,along with cardiac functional exercise training.The observation group patients underwent aerobic exercise with CPET assessment based on this,with the power at the anaerobic threshold one minute before being set as 80%of the peak power value obtained from the CPET assessment as the exercise load.The cardiac function,CPET,exercise ability and cardiac troponin I(cTnI),brain natriuretic peptide(BNP)and heart fatty acid binding protein(FABP)expression were detected.Results After intervention,cardiac function improved significantly in both groups,with superior outcomes in the observation group compared to the control group(P<0.05).The observation group exhibited significant improvements in peak oxygen pulse,peak oxygen consumption and anaerobic threshold compared to pre-surgery levels,(P<0.05)and outperformed the control group in these measures(P<0.05).Levels of cTnI,BNP and FABP decreased in both groups after the intervention,with the observation group showing significantly lower levels than the control group(P<0.05).Conclusion CPET-guided aerobic exercise rehabilitation during the perioperative period of CABG is effective in improving cardiopulmonary function of patients and reducing serum cTnI,BNP,and FABP levels in patients.
