The proportion of elderly patients undergoing isolated coronary artery bypass grafting (CABG) surgery has steadily increased. We have evaluated temporal trends in hospital outcomes of patients who were 75 years and older undergoing CABG (1990–2010) at our institution.

Data were collected prospectively for 3483 consecutive patients who were 75 years and older (median 78 years; range 75–94) undergoing isolated CABG at our institution over three time cohorts: 1990–96 (n = 817), 1997–2003 (n = 1534) and 2004–10 (n = 1132).

Overall mortality declined from 6.0% (49/817) in the earliest era (1990–96) to 1.9% (22/1132) in the most recent era (2003–10; P < 0.001). Mortality in low-risk patients (elective, primary surgery with the ejection fraction >40%) was 5.9% (13/220), 0.8% (4/514) and 0% (0/411) in the first …
