Key result
Overall graft patency rates were 52.6%, 64.6%, and 38.4% at 1, 5, and 10 years respectively, with age, smoking, and family history identified as independent risk factors for graft occlusion.
Why the study?
Postoperative CABG success depends on graft patency, but the ongoing atherosclerotic process affects native arteries and grafts, prompting investigation into how preoperative risk factors and angiographic disease extent affect long-term graft survival.
Do preoperative cardiovascular risk factors and coronary atherosclerosis severity predict long-term graft patency in patients who underwent CABG surgery?
Population
974 patients who underwent isolated CABG and subsequent coronary angiography during follow-up
Comparison
Preoperative cardiovascular risk factors and Gensini Score Index levels
Design
Observational cohort study

Risk factor associations with graft occlusion support intensified secondary prevention post-CABG; leaves open whether targeted modification improves patency in prospective studies.

Do preoperative cardiovascular risk factors and coronary atherosclerosis severity predict long-term graft patency in patients who underwent CABG surgery?
Preoperative cardiovascular risk factors and the severity of coronary atherosclerosis independently predict long-term graft occlusion after CABG surgery.
Sancar et al. (2021) conducted an observational in Coronary artery disease requiring CABG (n=974). Cardiovascular risk factors and coronary atherosclerosis severity was evaluated on Independent predictors of all graft occlusions. Overall graft patency rates were 52.6%, 64.6%, and 38.4% at 1, 5, and 10 years respectively, with age, smoking, and family history identified as independent risk factors for graft occlusion.
