Comparison of the Outcomes of Single vs Multiple Arterial Grafts in Women

Summary

The central hypothesis of ROMA:Women is that the use of multiple arterial grafting (MAG) will improve clinical outcomes and quality of life (QOL) compared to single arterial grafting (SAG). The specific aims of ROMA:Women are: Aim 1: Determine the impact of MAG vs SAG on major adverse cardiac and cerebrovascular events in women undergoing coronary artery bypass grafting (CABG). The investigators will compare major adverse cardiac and cerebrovascular events (death, stroke, non-procedural myocardial infarction, repeat revascularization, and hospital readmission for acute coronary syndrome or heart failure) in a cohort of 2,300 women randomized 1:1 to MAG or SAG. Differences by important clinical and surgical subgroups (patients younger or older than 70 years, diabetics, racial and ethnic minorities, on vs off pump CABG, type of arterial grafts used) will also be evaluated. The women enrolled in the ongoing ROMA trial (anticipated to be approximately 690) will be included in ROMA:Women, increasing efficiency and reducing enrollment time. Hypothesis 1.0. MAG will reduce the incidence of major adverse cardiac and cerebrovascular events. Hypothesis 1.1. The improvement with MAG will be consistent across key subgroups. Aim 2: Determine the impact of MAG vs SAG on generic and disease-specific QOL, physical and mental health symptoms in women undergoing CABG. The investigators will compare generic (SF-12, EQ-5D) and disease-specific (Seattle Angina Questionnaire) QOL and physical and mental health symptoms (PROMIS-29) in a sub-cohort of 500 women randomized 1:1 to MAG or SAG (including those enrolled in ROMA:QOL). Differences by important subgroups (as defined above) will also be evaluated. Hypothesis 2.0. MAG will improve generic and disease-specific QOL compared to SAG. Hypothesis 2.1. MAG will improve physical and mental health symptoms compared to SAG. Hypothesis 2.2. The improvement with MAG will be consistent across key subgroups.
