Filter by:The study will assess the safety and performance of the Fantom sirolimus eluting bioresorbable vascular scaffold (BVS) in the acute setting of myocardial infarction with unstable lesions and thrombogenic milieu.This is a prospective evaluation of clinical and patient related measures in STEMI patient who undergo urgent primary percutaneous coronary intervention (PCI) with stent implantation. Patients with culprit lesions with 2.5 - 3.5 mm diameter and located in one of the main coronary arteries will be included in the trial and prospectively observed. The study will comprise 20 patients, who will undergo additional evaluation with optical coherence tomography (OCT) and near-infrared spectroscopy/intravascular ultrasound (NIRS/IVUS) at baseline, 6 months, 18-24 months and 36 months. The device will be delivered in sizes 2.5 and 3.0 in diameter / 18 and 24 mm and 3.5 mm x 18 mm in length.
The registry study aims to discover the prognostic value of bio-markers in heart failure
Although great progress has been made in treating breast cancer, long-term health may be impaired by cancer therapy. For example, some chemotherapy drugs (e.g., anthracyclines) are known to cause declines in heart health. While the impact can vary, some will experience substantial heart damage that may lead to heart failure and death. As these treatments are highly effective, there is a need to find ways to reduce the damaging effects while not interfering with its anticancer potential. As it is well-known that regular exercise can improve heart health, the purpose of this study is to explore the role of exercise as a heart protective therapy for breast cancer patients receiving heart damaging chemotherapy.
This study is an ancillary (add-on) study to the clinical trial entitled "Effect of Nitric Oxide in Cardiac Surgery Patients With Endothelial Dysfunction", which has Clinical Trials.gov identifier NCT02836899. NCT02836899 trial randomizes cardiac surgical patients to receive either Nitric Oxide (NO) or a placebo during and after cardiac surgery. This ancillary study aims to assess the effects of Nitric Oxide on vascular responsiveness and on endothelial function during hemolysis in patients with pre-operative endothelial dysfunction undergoing cardiac surgery requiring prolonged cardiopulmonary bypass.
To test the hypothesis that estrogen suppression impairs endothelial dysfunction in endometriosis.
The objectives of this single site, randomized, crossover study is to evaluate the pharmacodynamic interactions between aspirin, NSAIDs and Coxibs with respect to platelet function, biomarkers of inflammation and endothelial function.
Metabolic changes related to disease are the precursor to anatomical changes in tissues. Currently the imaging methods routinely used in clinical practice look at the anatomical changes. Whilst these methods are very helpful in making clinical decisions, they are far from being perfect. Early disease can be missed because these methods are not sensitive enough and it is not clear whether disease is present or not. Additionally, it is also difficult to know whether disease it aggressive or non-aggressive. Hyperpolarised MRI is a new imaging tool that may allow addressing these deficiencies in current imaging technology. The process of hyperpolarisation allows the production of an injectable solution that can produce signal on a standard MRI scanner inferring information about the metabolism occurring at a particular location. This technology has only just become available for clinical use. The initial stages of evaluation require the investigators to refine and develop the new imaging protocols so that assessment can be made as to whether consistent results can be achieved. Additionally, refining the imaging protocol could also aid in identifying where the best potential future clinical use of this technology should be targeted. Within this application the investigators aim to try out hyperpolarised MRI in a number of different cancers and also see whether it is useful to assess cardiac metabolism. The investigators will be using 13C-labelled metabolites (for this study 13C- pyruvate) which will allow interrogation of glucose metabolism. The derangement of glucose metabolism is common to a number of disease processes.
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.
The purpose of this study is to examine how the environment and neighborhood characteristics affects the health of the area residents. The study will help determine how changing neighborhood characteristics, such as green space, affect heart health, risk factors for other diseases, sense of well- being or neighborhood cohesion.
Patients who are on chronic dialysis and 70 and older are frequently on multiple medications including statins. However, the benefit of statins in dialysis patient population is uncertain. Several randomized trials showed no benefit of statins on mortality in dialysis patient population. Guidelines recommend not starting statins in patients on dialysis who are not already taking them. However, there are no guidelines on what to do in patients who are already taking statins. The investigators are doing a short pilot study to discontinue statin in our dialysis patient population and evaluating the effects on discontinuation of statins on quality of life, cognition, as physical strength.
