Implication
Supports declining operative mortality for elderly CABG; leaves open whether era effects reflect technique advances or selection bias.
Structured PICO
Does the era of operation affect hospital mortality in elderly patients (≥75 years) undergoing isolated CABG?
P
Population
3483 consecutive patients aged 75 years and older (median 78 years; range 75-94) undergoing isolated coronary artery bypass grafting (CABG) at a single institution
I
Intervention
Isolated CABG surgery in the most recent era (2004-2010)
C
Comparator
Isolated CABG surgery in earlier eras (1990-1996 and 1997-2003)
O
Outcome
Hospital mortalityhard clinical
Operative mortality for isolated CABG in elderly patients (≥75 years) has significantly declined over two decades, demonstrating contemporary low risk, especially in elective cases with reasonable LV function.
