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.

Detailed description

ROMA:Women will leverage the infrastructure and the existing women population of the ROMA trial. ROMA:Women has two key Aims. In Aim 1, 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. In Aim 2, 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. Differences by important 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. ROMA:Women is a two-arm, international, multi-center, randomized clinical trial nested in the ROMA trial. ROMA:Women will include all the women enrolled in the parent ROMA trial and will leverage the existing ROMA infrastructure including clinical trial unit, database, case report forms (CRF), randomization system, site training resources, informed consent forms (ICF), regulatory approvals, Central Events Review Committee (CEC) processes/personnel, network of participating sites, site PIs, and study coordinators. The planned randomization procedure, interventions and treatment arms, outcome assessments and follow-up protocol of ROMA:Women are identical to those of the currently ongoing parent ROMA trial. The sites participating in ROMA will continue enrollment of women after the completion of the ROMA trial and additional sites will also be opened to reach the target sample size of ROMA:Women.

Conditions

• Heart Diseases
• Coronary Artery Disease
• Coronary Artery Bypass Grafting

Interventions

Type	Name	Description
PROCEDURE	Single arterial graft	This interventions consists of patients receiving the left internal thoracic artery to the left anterior descending coronary artery of the heart. In addition to the left internal thoracic artery patients will receive venous grafts for all additional grafting.
PROCEDURE	Multiple arterial grafting	This intervention consists of the patient receiving the left internal thoracic artery to the left anterior descending coronary artery of the heart. The second arterial graft (right internal thoracic artery or radial artery) will be directed to the major branch of the circumflex. Additional grafts will include saphenous veins or arterial conduits.
