Filter by:Cardiac rehabilitation (CR) is designed to increase healthy behaviours (e.g. physical activity, healthy eating, smoking abstinence) and reduce risk factors (e.g. high blood pressure & cholesterol) in order to improve quality of life and health among people with heart disease. Unfortunately, few patients attend CR, often reporting several barriers to access including travel distance, parking fees and lack of time. Advances in technology have the potential to improve accessibility and delivery of CR programs, and improve patient empowerment. The University of Ottawa Heart Institute has developed an e-health program called the Virtual Cardiac Rehabilitation Program (VCRP); an online cardiovascular health management system (website & Smartphone app) that provides strategies for the control and management of risk factors. The goals of VCRP are to: empower and educate patients; foster better communication between patients and their health care team; stimulate shared decision making; and, facilitate care coordination leading to better health outcomes. The VCRP provides patients with: real-time access to their health information, as well as tracking of risk behaviours and factors through integration with devices; a wellness plan; access to a personal on-line health coach; goal-setting notifications; on-line community forums; and, circle of care access to information. The aim of this project is to evaluate the effects of VCRP (with integrated fitness tracker) compared to a standard, home-based CR program. The study will look at changes in: patient empowerment; health behaviours; risk factors; quality of life; clinical outcomes; and, costs. The study will improve our understanding of: patient and provider needs; program usability; and shared decision-making. Results will inform the use of e-health programs such as VCRP into healthcare settings to improve patient empowerment, shared decision-making, and the ability to integrate wearable monitors to improve health behaviours.
The aim of this study is to evaluate the effect of adding Vildagliptin versus Glimepiride to Metformin on markers of inflammation, thrombosis, and atherosclerosis in diabetic patients with symptomatic Coronary artery diseases. The pre-specified established biological markers of inflammation, thrombosis, and atherosclerosis will include: Interleukin 1 beta (IL-1 beta)), hs-CRP, Atherogenic index and coronary risk index, Lipid profile. and adiponectin levels..
We hypothesize that human epicardial fat plays a thermogenic role to the myocardium. We hypothesize that epicardial fat may express genes of brown fat and thyroid function that are down-regulated by the presence of coronary artery disease. Because the postulated metabolic role of the epicardial fat, we also hypothesize that the gene expression of these regulatory thermogenic factors is higher in epicardial than subcutaneous fat This will be a cross-sectional study conducted over a one-year period in patients with or without coronary artery disease who require elective cardiac surgery regardless their participation in the study. Study group will be formed by 50 patients with clinically and angiographically established CAD who will undergo coronary artery bypass graft, as part of their standard medical care. Control group will be formed by 10 subjects, randomly selected, who will undergo cardiac surgery for aortic or mitral valve replacement as part of their standard medical care (these patients have no history, clinical signs of CAD, and show normal coronary arteries on coronary angiography). This will be a cross-sectional study conducted over a one-year period in patients with or without coronary artery disease who require elective cardiac surgery regardless their participation in the study. Adipose tissue will be collected during the cardiac surgery.
Computed Tomography Derived Fractional Flow Reserve (CT-FFR) is a noninvasive method for evaluating the hemodynamic significance of coronary artery lesions by using coronary CT Angiography (CCTA) as opposed to invasive FFR examination under invasive coronary angiography. The purpose of the CT-FFR-CHINA study is to verify that the diagnostic performance of hemodynamically significant lesions by CT-FFR is superior than routine anatomic evaluation of diameter stenosis using CCTA alone using invasive FFR as the reference standard, exclusively in Chinese population.
The deleterious effects of hyperuricemia (HUA) on cardiovascular disease (CVD) were well established. Aspirin is the most commonly prescribed antiplatelet agent for primary or secondary prophylaxis of CVD. Only a few short-term studies in the elderly suggested low-dose aspirin, e.g., 75-100 mg/day, increases serum urate by reducing urinary uric acid excretion. However, monitoring of renal function is currently not recommended. Little is known about the long-term effect of low dose aspirin on uric acid. The principal aim of this prospective cohort study therefore is to evaluate the renal effects of long-term aspirin (100 mg/d) administration in Chinese patients with coronary artery disease or other CVDs.
Analysis of certain biomarkers and transient myocardial perfusion deficit revealed by myocardial perfusion scintigraphy.
This study aims at identifying the etiology of troponin-T elevations in patients with atrial fibrillation visiting the emergency department.
Patients undergoing PCI for ACS are exposed to a significant ischemic and bleeding risk. The aim of our study is instead to analyze in detail the rates of recurrent events, but also their predictors and impact on outcomes, in a population of unselected real life patients treated with PCI for ACS discharged on either Clopidogrel, Prasugrel or Ticagrelor who already experienced an adverse event during the first year of follow up.
The Canadian Australasian Randomized Trial of Screening Kidney Transplant Candidates for Coronary Artery Disease (CARSK) will test the hypothesis that eliminating the regular use of non-invasive screening tests for CAD AFTER waitlist activation is not inferior to regular (i.e., annual) screening for CAD during wait-listing for the prevention of Major Adverse Cardiac Events. Secondary analyses will assess the impact of screening on the rate of transplantation, and the relative cost-effectiveness of screening.
EVAREST will identify and validate novel blood and imaging biomarkers of potential value for consistent and accurate interpretation of stress echocardiography. During phase one, blood samples will be collected to assess the impact of cardiac stress on levels of circulating biomarkers and examine whether the measurement of these biomarkers can provide additional prognostic information. Phases one, two and three will also determine whether novel imaging biomarkers can be identified in the echocardiograms that can be used for objective interpretation of the stress echocardiograms. EVAREST will recruit up to 8000 patients (First 500 during phase one, an additional 500 during phase two and an additional 7000 during phase three) from multiple hospitals across United Kingdom, who have been referred for a stress echocardiogram as part of their investigations into ischaemic heart disease. Phase four of the study will continue into a clinical study cohort phase to capture information from all patients referred for a stress echocardiogram in the UK, regardless of the reason for investigation.This registry phase will run for 2 years, recruiting up to 15000 participants.
