In a nationwide US analysis of 1,766,170 cardiovascular surgery admissions from 2016 to 2022, only 3,605 involved patients with multiple sclerosis, underscoring how limited the evidence base has been for this population.
After balancing-score matching, multiple sclerosis was not associated with significantly higher in-hospital mortality or a higher overall complication burden after coronary artery bypass grafting, valve surgery, aortic surgery, or combined procedures.
