Back in 1988, as many as 2.6% of patients having a coronary artery bypass graft (CABG) suffered a stroke associated with the operation. In those days, the criteria for who was eligible for bypass were stricter than it is today. Today, surgeons operate on older and sicker patients than ever. Yet the incidence of stroke has fallen dramatically since 1988. That’s the finding of Joseph Sabik, MD, chair of Thoracic and Cardiovascular Surgery at HVI. He came to this conclusion after an exhaustive study of 45,000 CABG surgeries done at Cleveland Clinic since 1982. Dr. Sabik attributes the drop in post-operative strokes to better screening of patients, better surgical techniques and better post-operative care. Read more about it here, here and here.
