Abstract

Objective We sought to compare the characteristics and outcomes of patients who were enrolled versus those who were not enrolled in the Stenting of Saphenous Vein Grafts (SOS) randomized controlled trial. Methods and esults We identified all patients who underwent saphenous vein graft stenting during the SOS Trial enrollment period (May 2005 and October 2007) at our institution. Baseline characteristics and clinical outcomes were compared between patients who were versus those who were not enrolled in SOS. Of the 97 patients who underwent saphenous vein graft stenting during the study period, 62 patients (64%) were enrolled in SOS. In the enrolled group, 62 patients with 91 lesions were randomized to a bare metal stent (BMS) (n = 39) or paclitaxel-eluting stent (n = 41). In the nonenrolled group, 35 patients with 44 lesions received a drug-eluting stent (DS) (n = 27) or BMS (n = 8). During a median follow-up period of 2.66 years, nonenrolled patients had higher mortality (31.4% vs 14.5%, P = 0.039), but lower rates of myocardial infarction (5.7% vs 32.3%, P = 0.005) and target vessel failure (37% vs 61.3%, P = 0.023). Overall, patients who received DS had lower incidence of myocardial infarction, target lesion revascularization, target vessel failure and major adverse cardiac events, and similar mortality compared with the BMS group. Conclusions Compared with nonenrolled patients, those who were enrolled in SOS had lower mortality. Patients receiving DS had better outcomes than those receiving BMS in both groups.
