The main objective of this study is to assess the safety, efficacy and dose response of LABR-312 administered intravenously at the time of percutaneous coronary intervention (PCI) with a drug eluting stent in reducing restenosis as measured by Optical Coherence Tomography (OCT) at 9 months post procedure in patients with diabetes mellitus (DM).

Administration of LABR-312 at the time of PCI will reduce restenosis compared with placebo as assessed by the OCT endpoint of % neointimal hyperplasia (%NIH) volume at 9 months in patients with DM.

Health behaviors like physical activity and nutritious eating habits significantly reduce initial stroke risk and help prevent strokes from reoccurring. Yet, most individuals struggle to meet physical activity and nutrition recommendations. Health and health behaviors are typically linked in couples, and spouses occupy a unique position to facilitate each other’s physical activity and healthy nutrition, thereby reducing stroke risk for everyone involved. 

This is a randomized, placebo-controlled, parallel-group, multi-center, double-blind, event driven study of vericiguat (MK-1242) in participants with HFrEF. The primary hypothesis is vericiguat (MK-1242) is superior to placebo in increasing the time to first occurrence of the composite of cardiovascular (CV) death or heart failure (HF) hospitalization in participants with HFrEF.

The Women's HARP study is a multi-center, diagnostic observational study employing standardized imaging protocols in women with MINOCA (MI with Non Obstructive Coronary Arteries) to determine the underlying diagnosis in each participant. Participants will be followed for recurrent clinical events, every 6 months, for a maximum of 3 years.

The AMPLATZER LAA Occluder is a transcatheter, self-expanding nitinol device intended for use in preventing thrombus embolization from the LAA. The purpose of this study is to compile real world outcome data on the use of AMPLATZER LAA Occluder in subjects with non-valvular atrial fibrillation (NVAF)

We hope to understand a heart failure patient's journey during the transition of care from the emergency department or hospital to home. We also want to explore how technology, like home health monitoring, can better support patients' recovery during this time.

The EARLY-AF study is centered on an evaluation of the impact of the early invasive management of Atrial Fibrillation. The primary goal of the study is to evaluate the clinical effectiveness of an early invasive approach. Specifically, the investigators are aiming to evaluate if PVI performed with the Arctic Front cryoballoon is superior to AAD as first-line therapy in preventing atrial arrhythmia recurrences (arrhythmia related symptoms, hospitalisations, and health care utilization).

Modern technology like computers, smartphones and the Internet enable patients to measure certain health indicators, like blood pressure and body weight, from the comfort of their own homes. This information can also be shared electronically with doctors and other healthcare providers to monitor remotely. This is called home health monitoring. In TEC4Home, we are developing a home monitoring solution for patients with heart failure to support their care and recovery at home after a visit to the emergency department.

The purpose of study is to test whether rivaroxaban added to standard of care treatment, when compared to placebo, has the potential to reduce the incidence of the clinical events related to the clots and complications of the heart and brain (CV death, MI, or stroke) or the legs (acute limb ischemia or major amputation) in patients who had undergone recent procedure(s) to improve the blood flow of their legs. 

INVESTED will test the hypothesis that high dose trivalent influenza vaccine will reduce cardiopulmonary events to a greater extent than standard dose quadrivalent influenza vaccine in high-risk cardiovascular patients with a recent history of myocardial infarction or heart failure. The trial will enroll 9300 participants over one Vanguard (pilot) season and three additional influenza seasons. The primary endpoint will be a composite of all-cause mortality or cardiopulmonary hospitalization.

A placebo-controlled, randomized, double-blind, parallel group, phase III multicenter study in subjects recently hospitalized for ACS and with the appropriate genetic profile. Subjects will provide informed consent before any study-specific procedures are performed. Subject enrollment may begin in the hospital and will continue following release from the hospital. Screening procedures may be performed at the time of the index ACS event or anytime thereafter, with the condition that randomization must occur within the mandated window (4-12 weeks after the index event).

Patients on the waiting list for kidney transplantation are at risk for coronary artery disease (CAD).  The optimal strategy to monitor and maintain the cardiac fitness of these patients is unknown. Currently patients without any symptoms of CAD undergo annual testing to determine if they have disease. This study will determine if screening is necessary.

The purpose of this clinical study is to test the hypothesis that market released Cardiac Resynchronization Therapy (CRT) devices which contain the AdaptivCRT® (aCRT) algorithm have a superior outcome compared to standard CRT devices in CRT indicated patients with normal atrio-ventricular (AV) conduction and left bundle branch block (LBBB).

This pilot study will investigate the impact of dexamethasone (DEX) on anti-Xa levels in participants taking apixaban 2.5 mg twice a day by mouth (PO BID). Investigators propose a prospective, cohort study of 24 participants with multiple myeloma, in whom a lenalidomide-dexamethasone (LEN-DEX)-based myeloma treatment regimen is indicated. Eligible participants will initiate thromboprophylaxis with apixaban prior to starting their DEX-containing regimen and continue until the end of cycle 3. Anti-Xa levels, D-Dimer and plasma drug concentration will be measured.

The purpose of this project is to conduct a proof of concept study in patients with probable Alzheimer's Disease who have mild to moderate hypertension, in order to determine if there is less global brain atrophy over one year, as measured by ventricular enlargement as a primary outcome measure, when patients are randomized to treatment with an angiotensin receptor blocker compared to an Angiotensin Converting Enzyme inhibitor (ACEI).

This study will be investigating the effects of fesoterodine on autonomic dysreflexia (AD) in patients with spinal cord injuries (SCI). The goal of the study is to examine the effect of increasing daily use of fesoterodine on episodes of high blood pressure triggered by urinary bladder contractions.

Recruitment Poster

Atrial fibrillation (AF) and atrial flutter (AFL) are cardiac rhythm problems where there is an irregular, rapid heart rate. Investigators plan to study Emergency Department (ED) patients with recent-onset episodes of AF or AFL (RAFF) where rapid heart rate requires urgent treatment to restore normal heart rhythm. RAFF is the most common rhythm disorder managed in the ED. Investigators recently showed that doctors use a wide variety of treatment approaches in Canadian EDs for RAFF.

This trial will enroll patients that have been diagnosed with a transient ischemic attack (TIA) or minor stroke that has occurred within the past 12 hours. Anyone diagnosed with a minor stroke faces the possibility of long-term disability and even death, regardless of treatment. Stroke symptoms such as weakness, difficulty speaking and paralysis may improve or worsen over the hours or days immediately following a stroke. TEMPO-2 is a minor stroke trial for patients presenting within 12 hours of their symptom onset. Patients will be randomized to TNK-tPA or standard of care.

The objective of C2R is to promote the rapid initiation and completion of enrollment in the CREST-2 randomized clinical trial (clinicaltrials.gov ID NCT02089217). Patients with severe symptomatic and asymptomatic carotid artery occlusive disease will be treated with carotid artery stenting (CAS) performed by experienced and skilled interventionists. Interventionists' eligibility will be determined by a multi-specialty Interventional Management Committee (IMC). Patient eligibility will include patients with standard or high-risk, symptomatic or asymptomatic carotid artery disease.

The purpose of this study is to determine the feasibility of conducting a large trial examining the effect on clinical outcome of a liberal red blood cell (RBC) transfusion strategy compared to a restrictive strategy (usual care) in patients with aneurysmal subarachnoid hemorrhage (SAH)
