Is redo coronary artery bypass graft in patients over 70 years old safe ?

Abstract EN

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.
