Background: CABG and PCI are effective means for revascularization of patients with multi-vessel coronary artery disease, but previous studies have not focused on treatment of patients that first undergo primary PCI., Methods: Among patients enrolled in the global registry of acute coronary events (GRACE), clinical outcomes for patients presenting with STEMI treated with primary PCI were compared according to whether residual stenoses were treated medically, surgically, or with staged PCI. Clinical characteristics and data pertaining to major adverse cardiac events during hospitalization and 6 months after discharge were collected., Results: Of the 1,705 patients included, 1,345 (79%) patients were treated medically, 303 (18%) underwent staged PCI, and 57 (3.3%) underwent CABG following primary PCI. Hospital mortality was lowest among patients treated with staged PCI (Medical = 5.7%; PCI = 0.7%; CABG = 3.5%; P < 0.001 [PCI vs. Medical]), a finding that persisted after risk adjustment (Odds Ratio PCI vs. Medical 5 0.16, [0.04-0.68]; P 5 0.01). Six month postdischarge mortality likewise was lowest in the staged PCI group (Medical = 3.1%; PCI = 0.8%; CABG = 4.0%; P = 0.04 [PCI vs. Medical]). Patients revascularized surgically were rehospitalized less frequently (Medical = 20%; PCI = 19%; CABG = 6.3%; P < 0.05) and underwent fewer unscheduled procedures (Medical 5 9.8%; PCI = 10.0%; CABG = 0.0%; P < 0.02)., Conclusions: The results of this multinational registry demonstrate that hospital mortality in patients who undergo staged percutaneous revascularization of multivessel coronary disease following primary PCI is very low. Patients undergoing CABG following primary PCI are hospitalized less frequently and undergo fewer unplanned catheter-based procedures., (© 2011 Wiley-Liss, Inc.)

Objectives: Our purpose was to evaluate long-term mortality and identify factors associated with 1-year mortality in patients who underwent elective percutaneous coronary intervention (PCI)., Background: While long-term outcomes in PCI patients have been reported previously, limited data are currently available regarding the comparative long-term outcomes in PCI patients who receive enoxaparin versus intravenous unfractionated heparin (UFH)., Methods: We conducted a follow-up analysis of clinical outcomes at 1 year in patients enrolled in the STEEPLE (SafeTy and Efficacy of Enoxaparin in Percutaneous coronary intervention patients, an internationaL randomized Evaluation) trial of 3,528 patients undergoing elective PCI. Patients were randomized to receive either intravenous 0.50-mg/kg or 0.75-mg/kg enoxaparin or intravenous UFH during elective PCI procedures. All-cause mortality at 1 year after index PCI was the main outcome measure., Results: Mortality rates were 1.4%, 2.0%, and 1.5% from 1 month to 1 year, and 2.3%, 2.2%, and 1.9% from randomization to 1 year, after index PCI in patients receiving 0.50 mg/kg enoxaparin, 0.75 mg/kg enoxaparin, and UFH, respectively. Multivariate analysis identified nonfatal myocardial infarction and/or urgent target vessel revascularization up to 30 days after index PCI (hazard ratio: 3.5, 95% confidence interval: 1.7 to 7.3; p < 0.001), and major bleeding within 48 h (hazard ratio: 3.0, 95% confidence interval: 1.1 to 8.5; p = 0.04) as the strongest independent risk factors for 1-year mortality., Conclusions: The 1-year mortality rates were low and comparable between patients receiving enoxaparin and UFH during elective PCI. Periprocedural ischemic or bleeding events were the strongest independent predictors of 1-year mortality. (The STEEPLE Trial; NCT00077844).

Stenting and GP IIb/IIIa inhibition are promising adjunctive therapies in PCI. The Global Registry of Acute Coronary Events (GRACE) is a registry of unselected patients with acute coronary syndromes, allowing for the study of treatments in a real-world environment. Data from GRACE patients with AMI who underwent PCI were analyzed. After adjusting for demographics, baseline characteristics, and previous medications, treatment with GP IIb/IIIa inhibitors and a stent and treatment with a stent alone were significant predictors of survival at 6 months. Stents were used in 90.9% of patients. GP IIb/IIIa inhibitors were used in 59.7%; in most cases they were started after the beginning of the procedure. The in-hospital death rate (7.6%) was highest in patients undergoing urgent PCI. Mortality at 6 months following PCI was 14.4% among patients who received neither GP IIb/IIIa inhibitors nor a stent, compared to patients who received both GP IIb/IIIa inhibitors and a stent (7.3%), GP IIb/IIIa inhibitors alone (12.8%), or a stent alone (6.7%)., (Copyright 2003 Wiley-Liss, Inc.)
