Phytosterols, Ezetimibe, and Cholesterol Metabolism

HypercholesterolemiaCoronary Heart Disease

Phytosterols and ezetimibe each reduce intestinal cholesterol absorption by 30-55% but appear to have different mechanisms of action. The investigators' hypothesis is that phytosterols and ezetimibe given together will block cholesterol absorption in an additive fashion. In a randomized, placebo-controlled crossover trial the effects of placebo, ezetimibe treatment and ezetimibe plus phytosterol treatment will be measured.

Pilot Study Evaluating the Safety of Electroducer Sleeve Medical Device for Temporary Cardiac Stimulation...

Coronary DiseaseValve Heart Disease1 more

During percutaneous cardiovascular intervention, temporary cardiac stimulation may be required. Usually this stimulation is generated via a temporary pacing catheter. In order to reduce the complexity of the procedure, a new stimulation strategy has been developed: the "Direct Wire Pacing technique".In this approach, the cardiac stimulation is provided via the guidewire connected to an external pacemaker. Previous study demonstrated the superiority of the new technique compared to the former. However this technique is likely to generate electrical pain, risk of bleeding for the patient and risk of blood exposure accident for the operators. This is why the medical device ELECTRODUCER SLEEVE has been developed. This device integrates a pacing function to the introducer and the guidewire used. The "Direct Wire Pacing technique" is simplified, secured and more reproducible.

Effect of Atlas Cedarwood Essential Oil Aromatherapy on Sleep Quality Among Patients With Coronary...

Sleep QualityCoronary Heart Disease

Sleep-wake disturbances were found to be a common problem among patients with CHD either earlier during hospitalization or/ and after discharge Although there is an evidence that sleep-wake disturbanes occur in high rate among patients with CHD little was found about assessment and management of this problem. This randomized controlled study will assess sleep quality of stable CHD patients who were admitted for undergoing coronary angiography electively. Then it will test the hypothesis that atlas cedar wood essential oil aromatherapy have a positive effect on sleep quality of CHD patients.

The Effect of a Healthy Diet Containing Flaxseed and Olive Oil on Cardiovascular Disease Risk Markers...

Coronary Artery Disease

Flaxseed and olive oil consumption have beneficial effects on cardiovascular risk factors. Nonetheless the effects of their simultaneous consumption have not yet been studied.The purpose of this study is to investigate the effects of a healthy diet containing flaxseed and olive oil compared with healthy dietary advice on cardiovascular disease risk markers in patients with coronary artery disease (CAD), in improving flow-mediated dilation, plasma lipid profile and fatty acids composition of red blood cells.

Effect of Permanent Internal Mammary Artery Occlusion on Extracardiac Coronary Collateral Supply...

CirculationCollateral3 more

Coronary artery disease and the benefit of bypasses: Despite considerable advances in medicine, cardiovascular diseases remain the number one cause of death globally, primarily consequence of myocardial infarction (MI). Coronary collaterals exert a protective effect by providing an alternative source of blood flow to a myocardial territory potentially affected by an acute coronary occlusion. Coronary collaterals represent pre-existing inter-arterial anastomoses and as such are the natural counter-part of surgically created bypasses. Sufficient coronary collaterals have been shown to confer a significant benefit in terms of overall mortality and cardiovascular events. In this regard, the concept of augmenting coronary collateral function as an alternative treatment strategy to alter the course of CAD, as well as to control symptoms, is attractive. Durable promotion of coronary collateral circulation: Before the advent of coronary artery bypass grafting, permanent augmentation of coronary collateral supply by a single structural modification has already been attempted. Bilateral ligation of the internal mammary arteries (IMA) was performed in CAD patients to alleviate angina pectoris and electrocardiographic (ECG) signs of ischemia. The prevalent in vivo function of natural IMA-to-coronary artery bypasses and their anti-ischemic effect has - for the first time - been recently demonstrated by our research group. The acute functional changes observed in response to temporary distal IMA balloon occlusion are expected to result in larger chronic structural adaptations of the IMA-to-coronary-artery connections when the distal IMA is permanently occluded. In contrast to the previously employed arteriogenic approaches in humans, the attractiveness of such an intervention lies in the potential durability of the effect. In a first step, catheter-based IMA occlusion ought to be conceptually investigated in the setting of the less frequently grafted right IMA among patients with ischemia in the right coronary artery territory.

Interventions to Support Long-Term Adherence aNd Decrease Cardiovascular Events Post-Myocardial...

Myocardial InfarctionCoronary Disease

Proven treatments exist that improve quality of life and reduce the risk of repeat heart attacks or death amongst persons who have already had one heart attack. These treatments include medications and supervised cardiac rehabilitation programs. Unfortunately, research shows that many people who have had a heart attack do not stick with these treatments and therefore cannot benefit. This quality improvement research program seeks to understand the impact of interventions that could be readily implemented at scale by entire health systems or organizations wishing to improve adherence to proven treatments. Specifically, the trial will test whether providing Ontario-based patients (and their health professionals) with repeated educational reminders delivered via post and phone will help improve the use of medications or attendance at cardiac rehabilitation. During the project, the types of patients who are most responsive will be identified as will the most cost-effective strategy for delivering reminders. The trial team are partnering in this project with health system decision makers who have an interest in using the results to create standard operating procedures that could benefit patients across the province.

Administration of Warm Blood Cardioplegia With or Without Roller Pump

Coronary Disease

The aim of this study is to compare the effect of warm blood cardioplegia administration with and without roller pump on perioperative myocardial injury, reflected by postoperative biomarker release, in patients undergoing coronary artery bypass grafting (CABG) with a minimal extracorporeal circuit (MECC).

Coronary Artery Disease (CAD)

The purpose of this study is to demonstrate that the strength of agreement between single photon emission computed tomography (SPECT) imaging with regadenoson following inadequate exercise stress testing and SPECT imaging with regadenoson alone is not inferior to the strength of agreement between two sequential regadenoson SPECT images without exercise.

Peripheral Stimulation Device to Improve Coronary Flow Reserve in Coronary Artery Disease

Coronary Artery DiseaseIschemic Disease

The purpose of the PERCCAD Study is to investigate the effect of the gekoTM device (a non-invasive calf muscle stimulator approved for use to improve blood flow by Health Canada) on coronary blood flow in order to assess its potential role as a therapeutic modality for the treatment of symptomatic coronary artery disease (CAD). This will occur in patients already undergoing coronary angiography and percutaneous coronary intervention (PCI) as part of their usual medical care. Further, the investigators will also assess the overall effect on blood flow in the body using non-invasive techniques. The primary objective of the PERCCAD study is to assess the effect of the gekoTM device on coronary blood flow in patients with symptomatic CAD who are undergoing invasive angiographic assessment and management with PCI. This evaluation of the gekoTM device is to be performed at the time of the patient's already planned invasive assessment and management so that invasive data can be collected without exposing the patient to risks other than those already associated with their planned procedure and usual clinical care. The secondary objective of the study is to assess the effect of muscle stimulation with the gekoTM device on endothelial function and peripheral blood flow measured via non-invasive techniques.
