Cardiovascular (CV) disease is the leading cause of death in Canada. Fifty percent of all Tc-99m used in nuclear medicine is for the diagnosis of coronary artery disease (CAD) with SPECT myocardial perfusion imaging (MPI). The reduced supply of Tc-99m requires other tracers to be investigated. Tl-201 SPECT is available but generally accepted to be inferior to Tc-99m. Rubidium (Rb-82), a nonreactor produced tracer, is believed to have superior accuracy compared to Tc-99m and Tl-201 SPECT, with 5-20 times lower radiation dose. In the U.S. Rb-82 generators have been FDA-approved since 1989 and are used increasingly for CAD diagnosis, but are still considered investigational in Canada. Objectives: To demonstrate that Rb-82 PET MPI is i) an accurate, cost-effective alternative to Tc-99m; ii) superior to Tl-201; iii) can be implemented in multiple Canadian centres for the diagnosis and management of CAD. Short term clinical outcomes of Rb-82 will be evaluated and compared to Tc-99m and Tl-201 SPECT MPI across Canadian imaging centres. Plan: Rb-ARMI is an innovative multidisciplinary, multi-centre imaging research initiative that builds on existing collaborative networks and Canadian industry partnership (DRAXIMAGE). Rb PET will be implemented, standardized and validated in 4 overlapping phases over 2 years, at 10 Canadian Centres. Impact: This project meets the expected goal to "lead to clinical trial applications and clinical validation studies which compare novel radiolabeled probes with those in current practice", and to "bring a new radiopharmaceutical to the clinic" within a short time frame. Increased use of Rb-82 PET MPI has the potential to reduce the demand for Tc-99m by 10-40%, effectively increasing the available supply for other procedures, and improving the standard of care for many Canadians at risk of heart disease.
Primary objective: To evaluate the impact of 12 weeks' administration of extended release niacin/laropiprant (ERN/LRPT) compared to placebo added to statin therapy on endothelial dependant dilatation of the arterial wall assessed by brachial vasoreactivity in stable coronary heart disease (CHD) patients. Secondary objective: To evaluate the impact of 12 weeks' administration of extended release niacin/laropiprant (ERN/LRPT) compared to placebo added to statin therapy on serum lipids and the parameters of inflammation in stable coronary heart disease (CHD) patients. CHD-coronary heart disease ER-extended release
The purpose of this study is to evaluate the long term clinical impact of routine follow-up coronary angiography after percutaneous coronary intervention (PCI). The primary endpoint is a composite of death/myocardial infarction/stroke/emergency hospitalization for acute coronary syndrome/hospitalization for congestive heart failure at 3-year after percutaneous coronary intervention.
The primary objective of this study is to evaluate the pharmacokinetic (PK) and safety associated with Supralimus-Core™ Sirolimus Eluting Coronary Stent system in the treatment of single de novo lesions in native coronary arteries between 2.5 to 3.5 mm in diameter.
The purpose of the study is to get a better understanding of patients who have multi-vessel coronary artery disease (blockages in more than one vessel bringing blood to the heart) and have either Hybrid Coronary Revascularization [HCR] (combination of surgery and catheter procedures to open up clogged heart arteries) or Percutaneous Coronary Intervention [PCI] (catheter procedures to open up clogged heart arteries). Participation in the study will last up to 21 months after a patient's heart procedure(s). The study collects information about the medical care patients receive during their planned procedure(s) and how well they do following the procedure(s). No new testing or procedures will be done. Patients will receive only the tests or procedures their doctor already has planned for them. The information collected should help to plan the design of a pivotal comparative effectiveness study of hybrid revascularization.
The Primary Objective is to show non inferiority in cardiac safety (i.e myocardial necrosis-MN- assessed by positive cardiac Troponin I -cTnI- ultrasensitive assay) of a Xenon based general anesthesia procedure in patients with elevated cardiac risk scheduled for atherosclerotic vascular surgery (i.e patient with Coronary Arteries Disease risk) when compared to sevoflurane based general anesthesia procedure, postoperatively up to 3 days.
XIENCE V USA is a prospective, multi-center, multi-cohort post-approval study. The objectives of this study are - To evaluate XIENCE V EECSS continued safety and effectiveness during commercial use in real world settings, and - To support the Food and Drug Administration (FDA) dual antiplatelet therapy (DAPT) initiative. This initiative is designed to evaluate the composite of all death, myocardial infarction (MI) and stroke (MACCE) and the survival of patients that are free from Academic Research Consortium (ARC) definite or probable stent thrombosis (ST) and that have been treated with drug eluting stents (DES) and extended dual antiplatelet therapy.
This is a Scripps pilot study on the effect of high clopidogrel maintenance dosing and its relationship to cytochrome P450 2C19 polymorphism status [STSI/CTSA].
Aspirin is very effective in protecting patients with coronary artery disease against adverse cardiac events, because it is a potent "antiplatelet agent". Some patients may develop a history of hypersensitivity to aspirin and treatment cannot usually be resumed in these patients. We have developed a rapid procedure to induce tolerance in these patients (SILBERMAN et al, Am J CARDIOL 2005;95:509-10) and wish to test whether aspirin is as effective as antiplatelet agent in patients with a history of allergy to aspirin and who undergo desensitization as it is in patients without history of hypersensitivity
