Filter by: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.
To compare treatment with Aspirin Protect® twice a day (100 mg in the morning and 100 mg in the evening) versus Aspirin Protect® 100 mg once per day on a composite end-point of ischemic events in diabetic patients, or in patients with a known risk factor for non-optimal aspirin response (obesity, abdominal obesity or coronary event occurring with long-term aspirin),with acute coronary syndrome. It is expected that aspirin taken twice a day will reduce the occurrence of new ischemic event after acute coronary syndrome in diabetic patients or in patients with a known risk factor.
The aim of the present study is to investigate whether the ingestion of a cocoa flavanol-containing drink compared to a flavanol-free drink, improves coronary vasomotion and platelet function in patients with overt coronary artery disease acutely (after 2 hours)
Purpose The TARGET All comers trial is a prospective, multicenter, randomized, two-arm, non-inferiority, open-label study with 1656 patients at 20 centers in Europe. The study is a "real world, all comers" study.
This is an investigator-initiated, prospective, single-centre, randomised, phase II, open-label study, testing the superiority of ticagrelor, as compared to clopidogrel, in modulating on-P2Y12 treatment platelet reactivity, endothelial dysfunction and inflammation in chronic obstructive pulmonary disease (COPD) patients receiving scheduled percutaneous coronary intervention (PCI) for stable coronary artery disease. Subjects that meet the inclusion criteria and have provided informed consent will be randomly assigned in a 1:1 fashion to one of the two dual antiplatelet therapy (DAPT) regimen: aspirin + clopidogrel (standard of care) vs. aspirin + ticagrelor (experimental arm). DAPT with aspirin and clopidogrel for at least 6 months (preferably 12 months) is the current gold-standard for patients receiving PCI and drug eluting stent implantation for SCAD. No data supports a different strategy and/or approach in COPD patients undergoing PCI. Ticagrelor, a new P2Y12 inhibitor, showed a significantly higher platelet inhibition as compared to clopidogrel. Recently, ticagrelor administration has been associated with a positive effect on endothelial function and a modulation of proinflammatory signalling. These actions are mediated by a significant influence of adenosine uptake. Higher platelet reactivity, chronic inflammatory response, heightened endothelial dysfunction characterized COPD patients with concomitant coronary artery disease (CAD). The investigators speculated that COPD patients undergoing PCI for stable CAD (SCAD) had a risk profile similar to that of acute coronary syndromes (ACS) patients. Accordingly, COPD patients undergoing PCI for SCAD may obtain a stronger benefit by ticagrelor as compared to clopidogrel. The aim of this study is to evaluate whether ticagrelor, is superior to clopidogrel, in reducing endothelial dysfunction , platelet reactivity (PR) and inflammation profile of patients with stable CAD and COPD. Ticagrelor will be administered according PLATO trial and international guidelines (180 mg as loading dose, 90 mg x 2 daily as maintenance dose). As suggested by international guidelines, the control group will be patients with current gold standard treatment for SCAD treated with PCI (aspirin + clopidogrel 75 mg daily). The evaluation of endothelial dysfunction, PR and inflammation profile will be repeated after 30 days and will be compared to baseline values.
Accessing the arteries of the heart through the blood vessels of the wrist is becoming increasingly popular. By obtaining access via the artery in the arm as opposed to the groin, there is less risk of complications and improved patient satisfaction. However, using the wrist can cause blockage of the artery after the procedure. If there is too little blood flow from a second artery that supplies the hand, this could result in significant injury. Therefore, it is important to test these blood vessels in the wrist prior to having this procedure. The best way to evaluate these arteries involves the use of ultrasounds but this takes a long time and is expensive. Therefore, the artery is usually evaluated with a clinical test known as the modified Allen's test, which relies on the doctor watching the flushing of the hand during compression of the artery. Currently smart phones with cameras are able to assess blood flow by passing light through the skin and watching differences in brightness. This may be a better way to assess the arteries in the hand as it is less subjective than simply watching the flushing of the hand. This study aims to assess the ability of an iPhone application in determining whether there is sufficient blood flow through the arteries of the wrist and comparing it to the clinical test commonly used.
Atherosclerotic disease is responsible for one third of all deaths annually and is a major cause of comorbidities. While atherosclerosis is by itself a benign disease, it often leads to complications such as acute myocardial infarction with ST-segment elevation. Rescue angioplasty is indicated if thrombolytic therapy fails. However, the benefits in reducing mortality and the amount of myocardium effectively saved are not well established. The development of new tools, including cardiac magnetic resonance imaging to identify myocardial area at risk and infarcted increased diagnostic accuracy. However, unlike the context of primary angioplasty, little is known about the relation between coronary epicardial and microvascular flow after rescue angioplasty and myocardial salvage. The objective of this study is to evaluate whether there is a relation between these flows and myocardial salvage identified by Magnetic Resonance Imaging (MRI). At the end of this research, the investigators hope to contribute to a better understanding of coronary flow and its relation to the amount of heart muscle saved after rescue angioplasty. This is an important information that can help understand which cases benefit most from rescue angioplasty.
This is a prospective, multi-center study to capture information on sensitivity and specificity of CADence using coronary angiogram as the gold standard, on subjects who are already scheduled for coronary angiography.
The purpose of this study is to explore the role of lipoprotein(a) and apolipoprotein(a) phenotype in fatal and non-fatal cardiovascular disease (CVD) events risk in coronary disease patients divided on the basis of management strategy - medical, endovascular or open cardiac surgery.
