In patients undergoing coronary artery bypass grafting (CABG), a novel analysis evaluating surgeon preference for multi- versus single-arterial grafting may help explain the differing results between prior retrospective analyses and randomized controlled trials regarding long-term survival.
A novel study to be presented on Friday, Jan. 24, at The Society of Thoracic Surgeons’ 61st Annual Meeting by lead author Justin Schaffer, MD, a cardiothoracic surgeon at Baylor Scott & White Health, offers fresh insights into the long-debated question of whether multi-arterial grafting (MAG) improves long-term survival compared to single-arterial grafting (SAG) in patients undergoing CABG. The analysis evaluates over one million Medicare beneficiaries and incorporates an innovative approach using surgeon preference as a tool to address unmeasured variables.
While the findings highlight nuances in interpreting retrospective and randomized trial data, they also underscore the need for future randomized studies, such as the forthcoming results of the ROMA trial, to definitively guide clinical decision-making.
The researchers emphasized that understanding the survival benefit of MAG over SAG requires randomized data, and it remains an important and open clinical question.
