Sex not independently linked to CABG mortality beyond baselines; supports refined risk adjustment but leaves generalizability open.
Cohort (n=1,258)
Does female sex independently influence hospital mortality in patients undergoing isolated on-pump coronary artery bypass?
Female sex does not independently increase hospital mortality after isolated on-pump CABG; observed differences are driven by baseline risk factor profiles.
Mandegar et al. (2008) conducted a cohort in Coronary artery bypass surgery (n=1,258). Female sex vs. Male sex was evaluated on Hospital mortality. Female sex did not have an independent influence on hospital mortality (overall rate 1.5%) after isolated on-pump coronary artery bypass, as differences were explained by baseline risk profiles.
