In this paper, the effect of the cognitive behavior combined with the biofeedback therapy on the evaluation of the emotional status in patients with coronary artery bypass grafting was evaluated. Fifty-two hospitalized patients who are planned to undergo coronary artery bypass grafting were randomly divided into the rehabilitation group and the control group under the normed space and the Banach space. The rehabilitation group was treated by the cognitive behavior combined with the biofeedback therapy. Compared with the control group, the patients in the rehabilitation group have decreased significantly under the normed space and the Banach space after the operation; while the 6 min walking distance of the patients in the rehabilitation group was increased significantly. The concentration of TNF-α of the patients in the rehabilitation group was significantly decreased and the time of the ventilator-assisted ventilation and the time of intensive care for the patients in the rehabilitation group was shorter than that in the control group. Compared to the preoperative conditions, the left ventricular ejection fraction of the patients in the rehabilitation group was significantly improved. Correlation analysis is carried out on the aforementioned observation indexes for the patients in the rehabilitation group. The results show that the decline in the normed space and the Banach space has significant positive correlation with the extension of the 6 min walking distance, respectively. Cognitive behavior combined with the biofeedback therapy could improve the anxiety and depression of the patients after undergoing the coronary artery bypass grafting, improve the exercise capacity and promote the recovery of the cardiac function.
