BACKGROUND: Patients treated with primary percutaneous coronary intervention (pPCI) for ST elevation myocardial infarction (STEMI) who have a history of coronary artery bypass grafting (CABG) are at high risk of adverse cardiovascular outcomes. Data on the risk of a saphenous vein graft (SVG)-infarct-related artery (IRA) compared to other culprit vessels are sparse.
METHODS: The study was based on a prospectively collected registry of 2,405 consecutive patients with STEMI attending a tertiary medical center in 2001-2017. Patients with an SVG-IRA (n = 172) were compared with patients with native vessel disease (n = 2,333) for mortality and major adverse cardiac events (MACE), which included death, myocardial infarction (MI), target vessel revascularization (TVR), and coronary artery bypass surgery (CABG) at 1 month and 3 years.
RESULTS: The SVG-IRA group was significantly older than the native vessel group (p = .05), with no between-group differences in rates of male patients (76 vs. 82%, p = .59), diabetes (24.2 vs. 26.2%, p = .73), and renal failure (18.8 vs. 9.2%, p = .25). Mortality was higher in the SVG-IRA group at 1 month (13.9 vs. 2.5%, p < .01) and 3 years (23.9 vs. 7.4%, p < .01). At 3 years, SVG-IRA was associated with the highest rates of MACE (55.6%), compared with native vessel disease. After correction for confounders, SVG-IRA remained an independent risk factor for MACE both at 1 month (HR-2.08, 95%CI 1.72-3.11, p < .01) and 3 years (HR-2.01, 95%CI 1.28-3.09, p < .01).
CONCLUSION: Among patients treated with pPCI for STEMI, outcomes are worse when the culprit is an SVG.
