Filter by:Introduction: Glutamine (GLN) is the most abundant free amino acid in the body. It modulates immune cell function and is an important energy substrate for most cells (especially for enterocytes and lymphocytes) in critical patients. GLN levels significantly decreased during sepsis/critical illness leading to an increase in infectious complications, organ failure and mortality. Moreover, in cases of ischemia/reperfusion injury in the myocardium, GLN increases the levels of Adenosine triphosphate (ATP)/Adenosine diphosphate (ADP) ratio and prevents intracellular lactate accumulation. Recently, the perioperative effect of intravenous and oral GLN treatment been associated in lowering levels of cardiac injury markers such as Troponin-I (TROP-I) and the number of postoperative complications in patients who underwent Cardiopulmonary Bypass (CPB). The aim of the study was to analyze the oral dose of preoperative oral GLN treatment in patients who underwent CPB with extracorporeal circulation in Mexican patients.
The Axxess™ Biolimus A9™ Eluting Coronary Bifurcation Stent System (AXXESS System; Biosensors, International, Morges, Switzerland) is a dedicated bifurcation stent, designed to cover the lesion at the level of the carina. Although deemed ideal for lesions involving only the proximal MV (1,0,0 according to Medina classification ref), this device may be used also in more complex bifurcation lesions when additional DES are required in the distal MV and/or in the SB. In the present registry the investigators report the performance and the efficacy of the self-expanding biolimus-eluting AxxessTM stent for the treatment of bifurcation lesions in a real-world population.
The investigators propose a single center prospective study that will assess two different strategies for measuring Fractional Flow Reserve (FFR) in patients undergoing clinically-indicated coronary angiography in whom FFR measurement is indicated. FFR will be measured with a non-side hole guide catheter (with the guide catheter both engaged and disengaged from the coronary ostium) and with a side-hole guide catheter (with the guide catheter both engaged and disengaged from the coronary ostium) to determine, whether measurements obtained with an engaged side-hole guide catheter are more accurate as compared with those obtained with the engaged non-side hole catheter.
The purpose of this research study is to improve statin medication adherence among Veterans with coronary artery disease with poor adherence to medications. The investigators are testing if newer technology pill bottle devices linked with individual feedback and/or social incentive strategies can improve medication taking behavior.
The purpose of this trial is to evaluate the clinical safety and efficacy of the Polymer-Free Drug-Eluting coronary stent system for the treatment of de novo lesions in native coronary arteries with a reference vessel diameter (RVD) that allows use of stents between 2.25 and 3.50 mm in diameter.
The FARGO trial is a prospective, randomized (1:1), multicenter study. The aim of the study is to assess the importance of fractional flow reserve (FFR) assessment prior to coronary artery bypass grafting (CABG) with respect to planning and guiding the revascularization strategy. The study compares an FFR-guided strategy to an angiography-guided strategy in patients planned for surgical revascularization.
In the trial cardiac patients will be provided with unrestricted access to the web-based eLearing platform for a one-month period.
Fractional flow reserve (FFR) is a pressure-wire-based index that is used during coronary angiography to assess the potential of a coronary stenosis to induce myocardial ischemia. Recent ESC guidelines referred to the usefulness of FFR extensively when noninvasive stress imaging is contraindicated, non-diagnostic, or unavailable. However, FFR requires additional manipulation with maximal and stable hyperemia by intravenous adenosine. More routine use of FFR for all angiographically significant stenoses would add considerable time, cost, and complexity to each PCI procedure and might also increase the risk of catheter-related complications such as coronary dissection and perforation. Although the guideline mentioned that FFR may not be useful in very high grade lesions (angiographically >90%) which always have an FFR <0.80, it have not been revealed yet proper criteria to predict FFR <0.80 obtained by angiographic parameters including degree of stenosis, lesion location and vessel size. It would be valuable to find more precise criteria available by conventional angiography for discrimination of functional stenosis in way to reduce the risk of additional procedure. For the purpose, the investigators will perform FFR in the lesions with significant stenosis (>70% diameter stenosis by visual estimation) and compare the angiographic parameters and FFR values in the study.
Abstract Objectives: Primary: To study the association between central aortic blood pressure indices and coronary artery disease in patients undergoing elective angiography. Secondary: (a) To study whether any association exists between central aortic pressure indices and the incidence of major adverse cardiovascular events (MACE) in the same patients during a 6 month follow up period. (b) To study whether any association exists between the central aortic pressures and peripheral pressures. Methods: The investigators conducted a prospective observational study in consecutive patients undergoing coronary angiography. Central and peripheral pressures were invasively recorded and coronary artery disease (CAD) classified into obstructive and non-obstructive group. CAD severity was graded using the Gensini score and subjects were divided into tertiles. Patients were followed up and the role of central aortic pressure indices in the prediction of cardiovascular events were analysed.
The objective of this clinical investigation is to demonstrate the safety and efficacy of an OCT guided strategy for stent implantation
