Options of the coronary artery bypass grafting type in patients with multivascular coronary artery blocage and patient’s quality of life

Objective: the aim of the study is to compare the life quality of patients with ischemic heart disease resulted from multivascular coronary artery blockage after CABG surgery on working heart (Off-Pump Coronary Artery Bypass) and CABG surgery in the environment of artificial circulation and on this basis to determine the most optimal choice of surgery depending on the projected life expectancy of the patient.

Materials and methods. The life quality of 40 patients with ischemic heart disease who had had CABG surgery was analyzed. All patients were separated into two groups, each consisting of 20 patients. Patients in the first group had CABG surgery on the working heart. The second group of patients had surgery on the arrested heart with artificial circulation. 6 and 12 months after surgery, the life quality of patients was assessed using SF-36 questioner.

Results. In comparison with the healthy population of the Russian Federation, patients’ physical functioning and mental health before surgery had been decreased to 23.6±3.3 and to 10.2±3.1 respectively (p<0.05). 6 months after surgery, the physical functioning of the first group patients increased by 5.7±1.0, whereas in the second group by 4.9±0.7. Mental health increased by 2.0±0.4 and 1.8 ±0.4 (p>0.05) respectively. 12 months after surgery patients’ physical functioning in the first group was higher by 4.9±0.1 in the second group and mental health by 3.4±0.7 (p<0.05) respectively.

Conclusion. Operations on the working heart should be performed in patients with a short predictable life expectancy with less than 40% ejection fraction of the left ventricular.
