    Although drug-eluting stents reduce restenosis and target lesion revascularization compared with bare metal stents (BMSs), the specter of late stent thrombosis has curbed enthusiasm for the widespread use of drug-eluting stents. Alternatively, increasing BMS use would increase restenosis and potentially increase adverse events. The presentation and outcomes of BMS restenosis are controversial. We evaluated 2,539 patients with BMS restenosis referred for repeat revascularization. Major adverse cardiac events, including mortality and myocardial infarction (MI), were assessed at clinical presentation, 30 days, and 6 months. Patients with acute presentation (i.e., unstable angina requiring hospitalization or MI) were compared with patients with stable presentation. At presentation, 19.2% of patients were asymptomatic, 27.5% had exertional angina, 46.6% had unstable angina, and 6.7% had MI. Mortality and MI rates were 1.1% and 1.4%, respectively, at 30 days and 3.3% and 4.5%, respectively, at 6 months. Patients with acute coronary syndrome (ACS) and those without ACS had similarly low mortality rates at 30 days (1.2% ACS vs 1.0% non-ACS, p = 0.65) and 6 months (3.4% ACS vs 3.3% non-ACS, p = 0.93) and MI rates at 30 days (1.3% ACS vs 1.4% non-ACS, p = 0.87) and 6 months (4.7% ACS vs 4.3% non-ACS, p = 0.65). Combined major adverse cardiac events were similar at 30 days (2.5% vs 2.1%, p = 0.53) and 6 months (7.4% ACS vs 6.9%, non-ACS, p = 0.65). In conclusion, although BMS restenosis often manifests as an ACS, it is associated with a low incidence of 6-month major adverse cardiac events and does not predict a negative outcome.
