Filter by:To evaluate the safety, efficacy and deliverability of the Combo bio-engineered sirolimus-eluting stent versus the Nano polymer-free sirolimus- eluting stents in the treatment of patients with de novo stenotic lesions of native coronary artery.
Patients with diabetes mellitus (DM) are at increased risk of atherothrombotic events. Importantly, DM is a key risk factor for the development of chronic kidney disease (CKD), which further enhances atherothrombotic risk. Clopidogrel is the most widely used platelet P2Y12 receptor inhibitor. However, despite its clinical benefit, patients with DM and CKD frequently experience recurrent atherothrombotic events. Ticagrelor is an oral, reversible, non-competitive P2Y12 receptor inhibitor with more potent and consistent platelet inhibition than clopidogrel. In large-scale clinical investigation, ticagrelor significantly reduced ischemic events to a greater extent than clopidogrel, a finding that was consistent also among DM patients. To date there has been no analysis on the efficacy of ticagrelor in DM patients according to CKD status. Moreover, although pharmacodynamic (PD) studies showed enhanced platelet inhibition associated with ticagrelor, it is unknown how this may be affected by CKD status. Ultimately, how PK/PD profiles of different ticagrelor dosing regimens may be affected by DM and CKD status is also unknown. The proposed study is aimed to show the impact of CKD status among patients with DM and coronary artery disease) CAD on PD and PK profiles of ticagrelor used at 2 doses (90mg bid and 60mg bid) in the setting of a prospective, randomized, cross-over trial.
The presence of Obstructive Sleep Apnea Syndrome (OSAS) has a high frequency in patients victims of a coronary artery disease (CAD) (myocardial infarction, revascularization). Unlike patients seen in a sleep Laboratory with an impact on daytime functioning, CAD apneic patients do not complain in their daytime functioning. The objective of this study is to explore whether the objective cognitive assessment measures may be a good marker of the efficacy of CPAP treatment given to non-sleepy apneic CAD patients. Coronary patients with an AHI between 15 and 40 / h will be treated (or not) after randomization with CPAP treatment. The expected results are: CPAP apneic coronary patients should have a positive impact on cognitive performance, particularly on attention span and working memory measured by improvement in the Paced Auditory Serial Addition Test score (PASAT score).
There are many patients hospitalized for chest pain, which don't have high risk features that require invasive coronary angiography, but are considered intermediate risk and for which ischemic heart disease can not be excluded. The current management for these patients is to perform a non invasive test in order to classify their risk. Exercise ergometry is a commonly used non invasive test to detect ischemia. that test is non-invasive, and does not involve radiation or intra-venous contrast. The test is limited for many patients, because of un-ability to exercise, or because of non-interpetable Electro Cardio-Graphy (ECG). Heart rate variability is well known to be a marker of ischemic heart disease. Heart rate variability testing is a non-invasive ECG monitoring technique. The study design is to identify hospitalized patients who are candidates for non-invasive stress testing, and to monitor their heart rate variability for one hour prior to the stress test.
Drug-coated balloon technology (DCB) has recently attracted considerable interest as a promising alternative treatment option, particularly in the setting of in-stent restenosis (ISR). Optical coherence tomographic finding of restenosis lesions in drug-eluting stents (DESs) after Balloon Angioplasty with Two Different Paclitaxel-Coated Balloons will be compared between two paclitaxel-coated balloon devices; Pantera Lux™ and SeQuent® Please.
This is a single-blinded, randomised, crossover investigation comparing the investigational device using intra-coronary (IC) Adenosine infusion to the standard intra-venous (IV) infusion method used for obtaining FFR measurements. All subjects requiring on a clinical basis a pressure wire assessment of intermediate coronary artery stenosis(es) will be eligible to take part in the investigation.
Clinical study on patients with turbid phlegm and blood stasis syndrome and Qi -Yin Deficiency syndrome of coronary artery disease (CHD) compared with normal cases will be launched. Detection of lipid metabolism, inflammation medium, endothelial cell injury, blood coagulation function evaluation of the relationship between disease and biochemical basis, detect plasma metabonomics and the gene expression profile chip, with "phlegm - lipid metabolic disorder", "stasis - microcirculation disorder", "alternating knot - inflammation mediated" and other system related to the biological basis. With Danlou Tablet for treatment, the investigators can observe result/effect index of turbid phlegm and blood stasis syndrome. Through comprehensive comparison of multi-level, multi-targets and multi-date biological index to discuss its sickness-syndrome-prescription corresponding relation and its biological basis.
To investigate different strategies of body positioning associated to early corporal mobilization and verify the impact int the time and quantification of thoracic and mediastinal drainage, pulmonary complications and time of intensive care units in hospitals stay. After first six hours post extubation in the first postoperative day and after evaluation and inclusion in the study, patients were randomized in three groups for receiving different strategies of body positioning associated to early mobilization with help of bed Hill Rom (Hill Rom Batesville@): Group 1: Control (GC n=33); Group 2: Continuous Lateral Rotation Group (TRCL n=34); Group 3:Positioning in sitting and Orthostatic (ORT n=34).
Cardiological examination is one of the major directions in nuclear medicine for detection of myocardial ischemia in patients with suspected coronary artery disease. In Caen, they constitute 20% of the activity of nuclear medicine. It is evaluating a new versatile innovative technology (IQ-SPECT) for performing rapid nuclear cardiological examinations (4 minutes) and quality on a SCINTI-CT camera for correcting the mitigation. This technical solution IQ-SPECT was made available to the nuclear medicine department in August 2011. To date, apart from the work on heart ghosts and one publication in abstract form in 2009, no other study have been published. The goal of the study is to study the technical performance of the innovative technology IQ-SPECT during a SCINTI-CT imaging in patients suspected of coronary disease .
The purpose of this study was to assess the safety and efficacy of Lumason-enhanced dobutamine stress echo (CE-DSE) in subjects having a suboptimal left ventricular endocardial border delineation (LV EBD) at rest and who were scheduled for coronary angiography.
