Key result
Octogenarians undergoing coronary artery bypass grafting or valve surgery had a higher risk of death compared with younger patients (RR 1.72; 95% CI 1.52-1.83).

Does being an octogenarian increase the risk of mortality and morbidity in patients undergoing coronary artery bypass grafting or valve surgery?
Relative Risk: 1.72 (95% CI 1.52–1.83)
Octogenarians undergoing CABG or valve surgery have significantly higher mortality and morbidity compared to younger patients, even after adjusting for confounding variables.
W M Johnson (2005) conducted a cohort in Coronary artery bypass grafting or valve surgery (n=7,726). Age ≥ 80 years (Octogenarians) vs. Age < 80 years (Nonoctogenarians) was evaluated on Mortality (RR 1.72, 95% CI 1.52-1.83). Octogenarians undergoing coronary artery bypass grafting or valve surgery had a higher risk of death compared with younger patients (RR 1.72; 95% CI 1.52-1.83).
