Key result
Octogenarians undergoing coronary artery bypass grafting had a significantly higher rate of emergency surgery compared to younger patients (53% vs 13.5%) and experienced high hospital mortality, particularly when ejection fraction was 45% or less (42% vs 5%).
Why the study?
Does coronary artery bypass grafting (CABG) result in acceptable hospital mortality and long-term survival in patients aged 80 years or older?

CABG in octogenarians is associated with high hospital mortality, particularly in emergency settings and patients with reduced LVEF, highlighting the importance of early surgical intervention before cardiac function deteriorates.

資正 et al. (2005) conducted an observational in Coronary artery disease requiring CABG (n=1,001). Age ≥80 years (undergoing CABG) vs. Age <80 years was evaluated on Incidence of emergency surgery (p=<0.0001). Octogenarians undergoing coronary artery bypass grafting had a significantly higher rate of emergency surgery compared to younger patients (53% vs 13.5%) and experienced high hospital mortality, particularly when ejection fraction was 45% or less (42% vs 5%).
