title: Effect of gender and race on operative mortality after isolated coronary artery bypass grafting.
abstract: Studies examining outcomes after coronary artery bypass grafting (CABG) by gender and/or race have shown conflicting results. It remains to be determined if, or how, gender and race are independent risk factors for CABG operative mortality. Using all consecutive patients who underwent isolated CABG at Baylor University Medical Center in Dallas, Texas, from January 2004 to October 2011, the risk-adjusted associations between gender and race, respectively, and operative mortality were estimated using a generalized propensity approach, accounting for recognized Society of Thoracic Surgeons risk factors for mortality. Women were nearly 2 times more likely to die during or within 30 days of the operation than men (odds ratio 1.96, 95% confidence interval 1.44 to 2.66, p <0.0001), while no significant mortality differences were observed among races. In conclusion, these findings suggest that women face a significantly greater risk for operative death that should be taken into account during the treatment decision-making process but that race is not associated with CABG mortality and so should not be among the factors considered.
