Objective To introduce the results and strategy of perioperative management undergo coronary artery bypass grafting (CABG) for patients older than 70. Methods One hundred and twenty one patients, 93.4%(113/121) of whom was complicated with other diseases, were retrospectively studied. Off-pump CABG (OPCAB) was used in 80 cases (66.1%). For the rest patients with severely compromised heart function or small target vessel with diffuse lesion, conventional CABG (CCABG) was selected. Left internal mammary artery (LIMA) was harvested leaving pleural cavity intact and grafted to left anterior descending artery (LAD). Saphenous vein(SV) was utilized for other anastomoses. Transit-time flowmeter (TTFM) was utilized to make sure that grafts were patent with satisfactory blood flow. Procedure of sternotomy and chest closure was carefully performed to decrease the complication of mediastinitis. Adequate nutrition and gradually increased physical activity were encouraged for "fast-track". Results Grafts were 3.08±0.75 for CCABG and 2.24±0.82 for OPCAB . LIMA was used in 90.9%(110/121) patients. One patient receiving emergency operation died of multiple organ failure syndrome resulting in mortality of 0.8%. The incidence of complication was 3.3%(4/121). The others recovered smoothly without any complication. Intubation time of OPCAB(10.04±5.68 h) was significantly shorter than that of CCABG(21.46±14.54 h). Patients were discharged within 12.22±5.56 days after operation. Conclusion Good short term result, namely low incidence of mortality and complication, could be obtained in patients older than 70 who underwent CABG through meticulous perioperative management.
