EID-LIDT, Guering et al. Long-term outcomes of saphenous vein graft stenting compared with native coronary artery stenting in patients with previous coronary artery bypass graft surgery. Arch. Cardiol. Méx. [online]. 2010, vol.80, n.1, pp.3-9. ISSN 1665-1731.

Objective: Our main objective was to compare the in-hospital and long-term outcomes of saphenous vein graft stenting and native coronary artery stenting in patients with previous coronary artery bypass grafting. Methods: We studied 127 patients who had prior coronary artery bypass; they were divided in two groups, according to the kind of percutaneous coronary intervention performed. The first group included 49 patients with saphenous vein graft stenting and the second group included 78 patients who underwent native coronary artery stenting. Results: There was no significant difference in age, incidence of diabetes, smoking, arterial hypertension, dyslipidemia, left ventricular ejection fraction or in the New York Heart Association functional class between both groups. The incidence of no reflow phenomenon was higher in group 1 (10.2% vs. 1.2%, p = 0.0001). The cumulative incidence of major adverse cardiac events was different between groups at 1 month (10.2% vs. 2.5%, p = 0.041). There was a lower MACE (major adverse cardiovascular events) free survival at 36 months in the saphenous vein graft stenting group (65.0% vs. 89.1%, p = 0.024). Conclusions: Major in-hospital complications occurred more frequently in the saphenous vein graft stented group. MACE-free survival at 3 years was higher in the native coronary artery stent patients.
