Narrow QRS HF Patients Assessed by ECG Belt

The purpose of this study is to quantitate electrical dyssynchrony in heart failure (HF) patients with a narrow QRS complexes ( 130 ms) using the ECG Belt. This is a pilot study that is designed to provide data that can be used in designing and implementing a prospective study of ...

Enhancing Community Health Through Patient Navigation Advocacy and Social Support

Although non-communicable chronic disease is the leading cause of death in Canada, many patients with chronic diseases do not receive guideline-recommended therapy for a variety of reasons. Lack of awareness of publicly funded programs, financial constraints, personal circumstances, language and cultural barriers make it challenging for patients to follow recommendations. ...

Ablation Versus Medical Management of Atrial Fibrillation in HFpEF

Recent studies using PVI for rhythm control in patients with heart failure with reduced ejection fraction (HFrEF) have shown improvement in systolic ejection fraction, exercise capacity, quality of life, and a significant reduction in all-cause mortality. The PVI procedure has been shown to be safe and comparably effective in treating ...

Family Genetics Health Education and Healthy Behaviors

Lifestyle behaviors, such as diet and physical activity, have been linked to the development of a number of diseases, including cancer, diabetes, and heart disease. Adopting a healthy diet and other preventive health practices are effective ways to reduce associated diseases. However, cancer, diabetes, and heart disease are etiologically complex ...

Phase N/A

Maternal Hyperoxygenation in Congenital Heart Disease

The aim of the study is to investigate the safety and feasibility of chronic maternal hyperoxygenation in pregnancies affected by fetal congenital heart disease, specifically those pregnancies in which the fetus has single ventricle physiology with aortic arch obstruction. The treatment has a potentially neuroprotective effect on the fetus. This ...


Impact of Retrograde Autologous Priming on the Coagulation Profile Assessed by Rotation Thromboelastometry (ROTEM) in Patients Undergoing Cardiac Surgery

Cardiac surgery with cardiopulmonary bypass (CPB) is associated with an increased risk of blood transfusions. The primary setup of the CPB circuit demands a priming volume of approximately 1600 mL of crystalloid solution which leads to a relevant hemodilution. The retrograde autologous priming (RAP) procedure minimizes hemodilution by displacing the ...

Ultrasound-Based Renal Sympathetic Denervation as Adjunctive Upstream Therapy During Atrial Fibrillation Ablation

The purpose of the ULTRA-HFIB Pilot is to determine the role of adjunctive renal denervation (RDN) in the prevention of AF recurrence in patients scheduled for an AF ablation procedure. Patients will be randomized to either i) AF ablation (Control) or ii) AF ablation + renal sympathetic denervation (Intervention). This ...

Handheld Ultrasound at Remote Locations

Handheld focused cardiac ultrasound in diagnosis of suspected heart failure Diagnostic ultrasound is more frequently used by clinicians in different scenarios. Echocardiography (cardiac ultrasound) is the most frequently method used when diagnosing heart failure (HF), cardiomyopathies, valvular pathology and cardiac tamponade, as well as other diseases affecting the heart, great ...

Phase N/A

The Influence of Catheter Ablation for Atrial Fibrillation on Atrial Electrical

From September 2017 to September 2019, the investigators enroll consecutive patients with symptomatic atrial fibrillation (AF) who were scheduled for an initial catheter ablation, including paroxysmal and persistent AF.Patients are divided in to three group: paroxysmal AF in radiofrequency ablation group, persistent AF in radiofrequency ablation group, and paroxysmal AF ...

Phase N/A

Environmental Polymorphisms Registry

We are establishing a registry-based cohort and repository of biological (e.g. blood, urine,saliva, etc.) and environmental (e.g. household dust) specimens (approximately 20,000 participants) in which the donated specimens are linked to the donor s identities, contact information, and some basic demographics through a personal identification number (PIN). Specimens are available ...
