Multiarterial vs Single-Arterial Coronary Surgery: Ten-Year Follow-Up of One Million Patients

This study examined the long-term survival of patients undergoing multiarterial grafting (MAG) versus single-arterial grafting (SAG) in coronary artery bypass grafting (CABG). After analyzing data from more than one million CABG patients, researchers found that MAG led to significantly better survival rates at 10 years, with both unadjusted and adjusted hazard ratios. MAG was also found to have an overall survival advantage over SAG in all subgroups, including stable coronary disease, acute coronary syndrome, and acute infarction.  Superior survival with SAG was only associated with patients who have a body mass index ≥40 kg/m 2.
