| Objective To compare the efficacy between off-pump coronary artery bypass grafting (OPCABG) and conventional coronary artery bypass grafting (CCABG) in treatment of those elderly patients with coronary artery diseases (CHD). Methods A total of 152 elderly patients (no less than 60 years old) with CHD admitted in our hospital between Jan 2015 and Jun 2017 were collected, and then divided into the CCABG group of 83 cases and the OPCABG group of 69 cases according to their operation plans. The perioperative relevant indicators between the two groups were compared, and the short-form 36-item (SF-36) health survey questionnaire (Chinese edition) was used to assess their postoperative quality of life. Results There was no significant difference between the two groups in the number of distal anastomotic vessels of vein grafts, operation duration, rate of twice thoracotomy and deaths in perioperative duration (all P>0.05). But the blood transfusion volume, ventilator supporting time, ICU stays, hospital stays and incidence of complications in the OPCABG group were significantly lower or shorter than those in the CCABG group (all P<0.05). The scores of social function, mental function, general vitality, role emotional and general health of SF-36 questionnaire in the OPCABG group were significantly higher than those in the CCABG group (all P<0.05), whereas there was no significant difference in the scores of bodily pain, physical function and role physical of SF-36 questionnaire between them (all P>0.05). Conclusion Application of OPCABG in treatment of those elderly patients with CHD may have significant clinical efficacy, including such advantages as less surgical trauma, fewer postoperative complications and faster recovery, which would be helpful to improve their postoperative quality of life. |
