ABSTRACT
Objective: The aim of this study is to examine the outcomes post redo CABG in patients above 70 years old
Method: This retrospective study was carried out at Liverpool Heart and Chest Hospital, for 148 patients above the age of 70 [Mean age 74.29+/-3.4 years] who underwent reoperation for Coronary Artery Bypass Graft [CABG] over 10 years period between 2001-2011. Post operative mortality and morbidity was analyzed. We used Major Adverse Vascular Events [MAVE] as in-hospital safety of treatment assessment tools
Results: The mean EURO score was 7.41+/- 2.67. Thirty-day mortality was 6% [9 out of 148], and the one-year survival was 84.4% [n=125]. MAVE show 4.7% post-operative Q-wave MI and 4% stroke. Renal impairment was noted in 14.2%. Rate of re-exploration was 12.8% mainly for bleeding and tamponade 8.1% and 2.7% respectively. Mean length of stay was 16.3 days
Conclusion: This study shows acceptable survival and post operative mortality and morbidity in this high risk group. Therefore, Redo CABG in patients over 70 alone should not deter a cardiac surgeon from offering such a potentially beneficial intervention
