Abstract
BACKGROUND The aim of this study is to compare the long-term prognosis of non-ST elevation acute coronary syndrome (NSTE-ACS) patients with 3-vessel disease (3VD) who underwent percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) or medical therapy (MT).Methods and Results:Overall, 3,928 NSTE-ACS patients with 3VD were consecutively enrolled from April 2004 to February 2011 at Fu Wai Hospital. Patients were followed up for a median of 7.5 years, and were divided into PCI, CABG or MT groups according to their treatment. Compared with patients undergoing PCI, CABG patients had lower rates of myocardial infarction (MI), unplanned revascularization, major adverse cardiovascular and cerebrovascular events (MACCE) and a higher rate of stroke (all P<0.05). Compared with MT, PCI and CABG had lower incidences of all adverse outcomes (all P<0.05), except for a similar rate of stroke between PCI and MT. Kaplan-Meier analysis showed similar results. After adjusting for confounders, CABG was independently associated with a lower risk of cardiac death, revascularization and MACCE compared with PCI (all P<0.05). Compared with MT, PCI reduced long-term risk of death, whereas CABG reduced long-term risk of death, revascularization and MACCE events (all P<0.05). CONCLUSIONS In NSTE-ACS patients with 3VD, CABG is independently associated with a lower risk of long-term cardiac death, revascularization and MACCE compared with PCI. Patients who received MT alone had the highest risk of long-term MACCE.

Abstract
OBJECTIVES There are limited data on bivalirudin monotherapy in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) with positive biomarkers of myocardial necrosis (troponin and/or creatine kinase-myocardial band isoenzyme). We sought to evaluate the safety and efficacy of bivalirudin monotherapy in patients with positive biomarkers from the Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial. PATIENTS AND METHODS We compared the net adverse clinical events [composite ischemia - (death, myocardial infarction, or unplanned ischemic revascularization) - or noncoronary artery bypass graft surgery (CABG)-related major bleeding] among patients with biomarker-positive NSTE-ACS in the ACUITY trial overall and by antithrombotic strategy. RESULTS Among 13 819 patients with NSTE-ACS enrolled in ACUITY, 4728 patients presented with positive biomarkers and underwent an early invasive strategy. Of those, 1547 were randomized to heparin plus a glycoprotein IIb/IIIa inhibitor (GPI), 1555 to bivalirudin plus GPI, and 1626 to bivalirudin monotherapy. Compared with biomarker-negative patients, biomarker-positive patients had higher 30-day rates of net adverse clinical events (14.0 vs. 12.4%; P = 0.04), all-cause death (1.3 vs. 0.5%; P = 0.001), cardiac death (1.1 vs. 0.5%; P = 0.005), and non-CABG-related major bleeding (6.5 vs. 5.2%, P = 0.03). At 30 days, bivalirudin monotherapy was associated with significantly less non-CABG-related major bleeding (bivalirudin monotherapy 4.1% vs. bivalirudin plus GPI 8.4% vs. heparin plus GPI 7.1%) with comparable rates of composite ischemia (bivalirudin monotherapy 9.2% vs. bivalirudin plus GPI 9.9% vs. heparin plus GPI 8.4%). In a multivariable model, bivalirudin monotherapy was associated with a significant reduction in non-CABG-related major bleeding but was not associated with an increased risk of death, myocardial infarction, unplanned revascularization or stent thrombosis. CONCLUSION Compared with heparin plus GPI or bivalirudin plus GPI, bivalirudin monotherapy provides similar protection from ischemic events with less major bleeding at 30 days among patients with NSTE-ACS and positive biomarkers.

Abstract
OBJECTIVES To determine the short-term clinical effects of levosimendan in acute myocardial infarction (AMI) patients with myocardial stunning after emergency percutaneous coronary intervention (PCI). METHODS The study population consisted of 30 patients with AMI who received emergency PCI and satisfied the inclusion criteria. Levosimendan was given as a continuous infusion of 0.1 μg/kg/min for 24 h, and the remaining 10 patients received placebo treatment. The patients were observed with invasive haemodynamic monitoring and were evaluated biochemically and echocardiographically before and after the drug infusion. RESULTS Following treatment, biochemical indices (not including creatine kinase and its MB fraction) were significantly lower in the levosimendan group than in the placebo group. Meanwhile, left-ventricular (LV) end-systolic volume, mean pulmonary arterial pressure, pulmonary capillary wedge pressure and systemic vascular resistance were significantly reduced in the levosimendan group, whereas the early-to-late diastolic velocities ratio, LV ejection fraction, cardiac index and cardiac power index were increased. Troponin I levels were reduced and fewer stunned and infarction segments were observed in the patients treated with levosimendan. CONCLUSIONS Levosimendan can significantly improve the myocardium function of patients with myocardial stunning after PCI.
