Randomized Controlled Trial Multicenter Study Comparative StudySecond-generation everolimus-eluting stents versus first-generation sirolimus-eluting stents in acute myocardial infarction. 1-year results of the randomized XAMI (XienceV Stent vs. Cypher Stent in Primary PCI for Acute Myocardial Infarction) trial.
The goal of this study was to compare the efficacy and safety of second-generation everolimus-eluting stents (EES) with first-generation sirolimus-eluting stents (SES) in primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). ⋯ In this all-comer, randomized, multicenter AMI trial, second-generation EES was noninferior to SES, and superiority for MACE was suggested. ST rate in EES at 1-year was low, but long-term follow-up and larger studies will have to show whether very late ST rates will also be improved in newer DES. (XienceV Stent vs Cypher Stent in Primary PCI for Acute Myocardial Infarction [XAMI]; NTR1123).

Randomized Controlled Trial Multicenter Study Comparative StudyPrognostic value of a high on-clopidogrel treatment platelet reactivity in bivalirudin versus abciximab treated non-ST-segment elevation myocardial infarction patients. ISAR-REACT 4 (Intracoronary Stenting and Antithrombotic Regimen: Rapid Early Action for Coronary Treatment-4) platelet substudy.
The ISAR-REACT 4 (Intracoronary Stenting and Antithrombotic Regimen: Rapid Early Action for Coronary Treatment-4) platelet substudy aimed to determine the relevance of high on-clopidogrel treatment platelet reactivity (HPR) in non-ST-segment elevation myocardial infarction patients that received abciximab with unfractionated heparin (UFH) or bivalirudin during percutaneous coronary intervention (PCI). ⋯ For patients with a risk profile similar to the subjects enrolled in this platelet substudy, the impact of HPR on clinical outcomes may depend on the type of adjunctive antithrombotic therapy used during PCI. Further investigations are warranted to clarify whether assessment of platelet function may help tailoring antithrombotic therapy during PCI.

Elevated plasma levels of neuropeptide proenkephalin a predict mortality and functional outcome in ischemic stroke.
The purpose of this study was to investigate neuropeptides in patients presenting with symptoms of acute cerebrovascular disease. ⋯ PENK-A is a prognostic biomarker in the acute phase of ischemic stroke. Elevated PENK-A concentrations are associated with ischemic stroke, severity of cerebral injury, and may have prognostic value for fatal and nonfatal events.
