Key result
Female gender was associated with a significantly higher 180-day mortality (12.3% vs 8.2%, HR 1.632) compared to male gender among septuagenarians undergoing isolated coronary artery bypass graft surgery.

Does female gender increase 30-day and 180-day mortality in patients over 60 undergoing isolated CABG?
Hazard Ratio: 1.632 (95% CI 1.212–2.2)
Absolute Event Rate: 12.3% vs 8.2%
p-value: p=0.001
Female gender is an independent risk factor for 180-day mortality, but not 30-day mortality, in septuagenarian patients undergoing isolated CABG.
Arif et al. (2016) conducted a cohort in Coronary artery disease requiring isolated coronary artery bypass graft surgery (n=4,972). Female gender vs. Male gender was evaluated on 180-day mortality in septuagenarians (HR 1.632, 95% CI 1.212-2.200, p=0.001). Female gender was associated with a significantly higher 180-day mortality (12.3% vs 8.2%, HR 1.632) compared to male gender among septuagenarians undergoing isolated coronary artery bypass graft surgery.
