Filter by:The objectives of the 2-year study are two-fold: 1. To determine the 5-7 year patency rate (rate of open bypass grafts) of the LITA graft of patients who have already had robotically-assisted CABG surgery using CTA and MPS-MIBI 2. To determine patient quality of life at 5-7 years after robotically-assisted CABG surgery
Advances in mechanical intervention (PCI) and anticoagulation therapy have been the cornerstone of treatment of patients with coronary artery disease. However, the large diversity of approaches to anticoagulation during PCI introduces gaps in knowledge regarding management of cardiac patients. As such, we have initiated a national PCI registry to elucidate anticoagulant choice, dosing strategies, case selection dynamics, and clinical outcomes in the Canadian health care environment.
The purpose of this study is to determine the effects of pioglitazone, once daily (QD), on heart functioning before, during and after stent implantation.
The purpose of this study is to evaluate the safety and efficacy of dosing with mipomersen for 26 weeks in patients with high cholesterol who are on a maximally tolerated dose of statin and who have a diagnosis that puts them at least at high risk of coronary heart disease (CHD).
The zotarolimus-eluting Endeavor Resolute stent is not inferior to the everolimus- eluting Xience V stent platform regarding a composite of cardiac death, myocardial infarction or target lesion revascularisation in a real-world population.
In this study the investigators will investigate whether a short pretreatment (3-7 days) with dipyridamole 200mg twice daily will protect patients against myocardial injury sustained during an elective dotter operation of the coronary arteries (PCI). The investigators hypothesize that dipyridamole can reduce myocardial injury sustained during elective PCI.
We sought to determine whether the dual-source computed tomography assessment of aortic valve stenosis and coronary artery disease is equivalent to or even better than conventional invasive coronary angiography and transthoracic echocardiography.
Positron Emission Tomography (PET) is a non-invasive, unique nuclear imaging technique that allows the evaluation of blood flow in the heart and provides information about the cell activity of specific organs such as the heart and brain. It also provides useful information for the management of patients with poor pumping function of the heart, heart failure, and coronary artery disease. A cardiac viability imaging looks at how the heart uses glucose (sugar) The imaging process determines areas of the heart that are alive (viable - using sugar) versus areas of the heart that are scar tissue (non-viable). F-18 fluorodeoxyglucose (FDG) is the radioactive substance used to determine myocardial viability. This nuclear imaging technique has been shown to be useful in directing management for patient care. The Ministry of Health recognizes the clinical utility of FDG PET imaging for myocardial viability assessment and other cancer indications. Optimizing the potential advantages of FDG PET in Ontario, will require characterization of the patient population, referral patterns, upstream and downstream resource utilization and patient outcomes. Therefore, registry studies are being undertaken to provide specific information about the utility of PET in these clinical situations in Ontario. The proposed registry will facilitate monitoring of the implementation of this limited technology and allow continued evaluation of practice patterns and outcomes. The University of Ottawa Heart Institute is the coordinating centre for this project with PET centres in London, Hamilton and Toronto also participating. The purpose of this study is to evaluate the utility of FDG PET viability imaging in the decision making process for patients with poor left ventricular function who may be candidates for revascularization and to study the downstream effect of the clinical management decisions. Patients meeting specific inclusion criteria will be eligible for this study.
This study aims to assess the potential for ischaemic peri-conditioning (IP) in elective percutaneous coronary intervention (PCI) patients to attenuate ischaemia in an animal model of myocardial infarct.
Aim of this study is the determination of a valid procedure for ischemia diagnositc in postmenopausal women.
