OC52 OCTOGENARIANS UNDERGOING OFF-PUMP AND ON-PUMP MULTIPLE CORONARY ARTERY BYPASS GRAFTING BENEFIT OF GOOD QUALITY OF LIFE AT MID-TERM FOLLOW-UP

Abstract

Abstract Aim of the study: To review mid-term results of multiple off-pump and on-pump CABG in octogenarians (OPCABG-ONCABG). Materials: In the period 2012–2017 87/888 (9,8%) patients undergoing isolated multiple CABG were octogenarians (81,7 ± 1,6 years). In particular 32/87 (36.78%) underwent OPCABG. After propensity score analysis, 29 OPCABG patients were matched with 29 ONCABG. Results: Mean number of grafts was respectively 2,6 ± 0,6 and 2,1 ± 0,3 in ONCABG and OPCABG group (p = 0,001). In-hospital mortality and perioperative MI did not occur. 1 ONCABG patient suffered from a stroke. IABP was implanted in 1 patient in each group. Intraoperative blood transfusions did not differ significantly in the 2 groups (respectively 18/29–62,1% and 14/29–48,3% in ONCABG and OPCABG, p = 0,2). 1 ONCABG patient needed surgical revision for excessive bleeding. Mean intubation time was respectively 9,2 ± 4,58 and 9,8 ± 3,64 hours in ONCABG and OPCABG group (p = 0,6). Mean stay in ICU did not differ in the 2 groups (p = 0,4). Severe AKI occurred in 1 ONCABG patient requiring haemodialysis. Follow-up was 77.6% complete. At a mean follow-up of 2.7 ± 1.5 years 41/45 patients are alive (2 non cardiac death for each group). In table 1 is reported Kaplan-Meyer cumulative survival curve. Only 2/41 patients had a new hospital admission for NSTEMI and 39/41 are angina free. Conclusion: OPCABG and ONCABG are safe procedures even in elderly patients. Postoperative complications seem to be less frequent in OPCABG patients, but the difference is not significant. OPCABG received significantly lower number of grafts, but this does not seem to influence survival and angina recurrence.
