Thrombotic events such as myocardial infarction or stent thrombosis are the major cause of adverse outcomes in patients undergoing percutaneous coronary intervention (PCI). While current antiplatelet agents, anticoagulants, and PCI techniques have reduced the risk of thrombotic events in PCI-treated patients, a considerable hazard still remains. Cangrelor is an intravenous P2Y12 receptor antagonist that provides a rapid onset and maximal platelet inhibition, which is quickly reversible. In the large-scale CHAMPION PHOENIX trial, cangrelor was shown to reduce ischemic events significantly, including myocardial infarction and stent thrombosis, without increasing the risk of severe bleeding across the full spectrum of patients undergoing PCI, with substantial benefits in all patient subgroups examined...

Non-ST segment elevation acute coronary syndrome (NSTE-ACS) can be difficult to diagnose accurately, especially in the hyper-acute phase. Non-ECG-gated contrast-enhanced computed tomography (non-ECG-gated CE-CT) has been used in many institutions for screening acute chest pain. Although early defects (EDs) observed in non-ECG-gated CE-CT have been reported as a sign of acute myocardial ischemia, the precise diagnostic value of this sign for acute coronary syndrome has not been fully elucidated. We investigated the usefulness of non-ECG-gated CE-CT for the diagnosis of NSTE-ACS...

BACKGROUND: Low T3 which is defined as decreased triiodothyronine (T3) and normal thyroid-stimulating hormone (TSH) and thyroxin (T4) levels is present in many acute diseases and is related to increased mortality. We studied low T3 level's relation to long-term mortality in non-ST-elevation acute coronary syndrome (NSTE-ACS) patients. METHODS: T3, T4, and TSH levels of consecutive NSTE-ACS patients were measured. Patients with normal T4 and TSH levels, but low T3 level were defined as low T3 group...

Current guidelines recommend initiation of a P2Y12 inhibitor for all patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) at the time of diagnosis (pre-treatment); however, there are no randomized trials directly comparing pre-treatment with initiation at the time of angiography to support this practice. We explore clinical and institutional parameters potentially associated with benefit with this strategy in a decision-analytic model based on available evidence from randomised trials. A decision analysis model was constructed comparing three P2Y12 inhibitors in addition to aspirin in patients with NSTE-ACS...

BACKGROUND: Consistent evidence of benefit exists for radial access (RA) in ST-elevation acute myocardial infarction (STEMI). Patients with non ST-elevation acute coronary syndrome (NSTE-ACS) have a more varied ischemic and bleeding profile. No randomized trial of vascular access ever focused on NSTE-ACS and landmark studies did not provide conclusive results in this heterogeneous subset of patients. METHODS: We assessed in a meta-analysis whether RA is associated with improved outcomes in NSTE-ACS patients...

Two-dimensional speckle tracking echocardiography (2D-STE) multilayer analysis of myocardial deformation is a non-invasive method that enables discrimination of transmural differences owing to myocardial ischemia or necrosis. We wished to ascertain if multilayer longitudinal strains at rest are associated with significant (≥70 %) stenosis of the left anterior descending coronary artery (LAD) in patients with suspected non-ST-elevation acute coronary syndrome (NSTE-ACS). Our cohort comprised 113 consecutive patients with suspected NSTE-ACS and preserved ejection fraction (EF)...

Platelet aggregation is a crucial feature in coronary artery thrombus formation and is a major causative factor in both acute coronary syndromes (ACS) and reocclusion after percutaneous coronary interventions (PCI). The glycoprotein (GP) IIb/IIIa (αIIbβ3) integrin receptor is the pivotal mediator of platelet aggregation. In late 1990s, the introduction of GP IIb/IIIa inhibitors (GPI) was associated with a reduction of ischemic complication, and a clear clinical benefit in PCI during ACS, for both non ST-elevation (NSTE) and ST-segment elevation myocardial infarction (STEMI)...

BACKGROUND: We explored benefits and risks of an early invasive compared with a conservative strategy in women versus men after non-ST elevation acute coronary syndromes (NSTE-ACS) using the ISACS-TC database. METHODS: From October 2010 to May 2014, 4145 patients were diagnosed as having a NSTE-ACS. We excluded 258 patients managed with coronary bypass surgery. Of the remaining 3887 patients, 1737 underwent PCI (26% women). The primary endpoint was the composite of 30-day mortality and severe left ventricular dysfunction defined as an ejection fraction <40% at discharge...

IMPORTANCE: In the current therapeutic era, the risk for sudden cardiac death (SCD) after non-ST-segment elevation acute coronary syndrome (NSTE ACS) has not been characterized completely. OBJECTIVE: To determine the cumulative incidence of SCD during long-term follow-up after NSTE ACS, to develop a risk model and risk score for SCD after NSTE ACS, and to assess the association between recurrent events after the initial ACS presentation and the risk for SCD. DESIGN, SETTING, AND PARTICIPANTS: This pooled cohort analysis merged individual data from 48 286 participants in 4 trials: the Apixaban for Prevention of Acute Ischemic Events 2 (APPRAISE-2), Study of Platelet Inhibition and Patient Outcomes (PLATO), Thrombin Receptor Antagonist for Clinical Event Reduction in Acute Coronary Syndrome (TRACER), and Targeted Platelet Inhibition to Clarify the Optimal Strategy to Medically Manage Acute Coronary Syndromes (TRILOGY ACS) trials...

Data are scant regarding serum bilirubin levels in non-ST-segment elevation acute coronary syndrome (NSTE-ACS). In this study, we evaluated the role of serum bilirubin levels in NSTE-ACS. We enrolled 782 patients who presented to the emergency department with acute chest pain. Patients were divided into 2 groups based on the troponin positivity. Patients with NSTE-ACS who had troponin positivity were included in group 1 (n = 382), and group 2 consisted of the control patients (n = 400). Direct bilirubin (DB) levels (group 1: 0...

The 2015 non-ST-segment elevation acute coronary syndromes guidelines of the European Society of Cardiology have been published 4 years after the previous edition. A new algorithm was presented for the diagnosis of acute myocardial infarction based on the measurement of high-sensitivity cardiac troponin levels at presentation and at 1 hour, including a guidance on the duration of cardiac rhythm monitoring. New recommendations address the management of antiplatelet therapy regarding duration of dual antiplatelet therapy, in patients requiring long-term anticoagulation or undergoing urgent coronary artery bypass surgery as well as of acute bleeding events related to antithrombotics...
