RESUMO

OBJECTIVES: To compare outcomes of patients receiving drug-eluting stents (DES) versus bare metal stents (BMS) during percutaneous coronary intervention (PCI) of saphenous vein bypass grafts (SVG). BACKGROUND: Long-term benefits of DES versus BMS are well established for native vessel PCI. Benefit in patients undergoing SVG intervention is less certain. We used data from a multicenter registry (evaluation of drug eluting stents and ischemic events, EVENT) to compare outcomes among patients treated with DES versus BMS 1-year following SVG interventions. METHODS: Between July 2004 and December 2007, 684 patients in EVENT underwent SVG PCI (515 DES only, 169 BMS only). The primary endpoint was a composite of death, myocardial infarction (MI), and target lesion revascularization between hospital discharge and 1-year follow-up. Propensity score stratification was used to adjust for differences between groups. RESULTS: Baseline demographic and clinical characteristics of patients treated with DES and BMS were similar. The DES group had fewer men and a higher prevalence of prior PCI. Patients receiving DES had less angiographic thrombus, less frequent use of embolic protection devices, greater total stent length, and smaller maximum stent diameters. Unadjusted outcomes between discharge and 1-year follow-up did not differ between the groups. After risk adjustment, the primary outcome was less frequent among patients treated with DES (adjusted HR = 0.48, 95% CI = 0.27-0.84, P < 0.01) with similar relative benefits across the individual endpoints. CONCLUSIONS: Among patients undergoing SVG PCI in a "real world" registry analyzed using propensity score stratification, treatment with DES compared with BMS was associated with reduced MACE at 1 year following PCI.

RESUMO

Left ventricular free wall rupture is an uncommon complication after a myocardial infarction that is associated with a high mortality rate from pericardial tamponade, especially in the elderly. Early recognition and management of this clinical entity affects the outcome; therefore, a high index of suspicion is imperative. We present a case of an 80-year-old man admitted with myocardial infarction, who had subsequent findings of left ventricular free wall rupture complicated by pericardial tamponade. Emergent surgical repair led to successful recovery. A brief overview of the clinical presentation, diagnosis, and management of this challenging and potentially fatal complication is presented.
