To jump or not to jump? A multicentre propensity-matched study of sequential vein grafting of the heart†.
Interactive Cardiovascular and Thoracic Surgery 2019 March 19
OBJECTIVES: In this propensity-matched study we investigated the outcome after grafting with either a single vein or a sequential vein grafting strategy. Outcomes were primarily risk of reintervention and death in the short, intermediate and long term (10 years).
MATERIALS: In the period from 2000 to 2016, data from 24 742 patients undergoing coronary artery bypass grafting were extracted from the Western Denmark Heart Registry, where data are registered perioperatively. We used a propensity-matched study in which the study groups were matched on parameters primarily from the EuroSCORE. The numbers of patients in both groups after matching were 3380.
RESULTS: Single grafts resulted in significantly more postoperative bleeding and were more time-consuming. No differences were seen regarding in-hospital events such as stroke, acute myocardial infarction, dialysis or arrhythmias. After 30 days, patients in the jump graft group showed an increased rate of reintervention due to ischaemia after adjusting for confounding factors [hazard ratio (HR) 2.08, 95% confidence interval 1.01-4.34]. In addition, after adjusting for known confounders, sequential grafts were found to increase the risk of mortality at 6 months (HR 1.51, 95% confidence limits 1.07-2.11) and 5 years (HR 1.23, 95% confidence limits 1.04-1.46).
CONCLUSIONS: This propensity-matched analysis suggested, although discretely, that a jump graft as a grafting strategy is associated with a slightly increased risk of mortality and early graft failure and that a single grafting strategy to the coronary arteries should be preferred when feasible.
