Does a similar procedure result in similar survival for women and men undergoing isolated coronary artery bypass grafting?

Abstract Objectives To (1) identify sex-related differences in risk factors and revascularization strategies for patients undergoing coronary artery bypass grafting (CABG), (2) assess whether these differences influenced early and late survival, and (3) determine whether clinical effectiveness of the same revascularization strategy was influenced by sex. Methods From January 1972 to January 2011, 57,943 adults—11,009 (19%) women—underwent primary isolated CABG. Separate models for long-term mortality were developed for men and women, followed by assessing sex-related differences in strength of risk factors (interaction terms). Results Incomplete revascularization was more common in men than women (26% vs 22%, P
