Filter by:The purpose of this research study is to investigate the link between age-related macular degeneration (AMD or ARMD) and coronary artery disease (CAD). Age-related macular degeneration is a medical condition which may result in blurred or no vision in the center of vision. Coronary artery disease is a blockage of one or more arteries that supply blood to the heart. The study will specifically look at the macular changes that occur in the retina, which is the sensory membrane that lines the inner surface at the back of the eyeball, and the relationship between coronary heart disease and the risk factors.
Traditional randomized clinical trials (RCTs) have provided extremely valuable information on medical therapies and procedures that have changed the way heart diseases are treated. However, despite these contributions, traditional RCTs are costly, the findings may not be applicable to patients unlike those in the study, and the use of trial findings may be infrequent. These limitations may be addressed by incorporating 'big data' in RCTs, which is the emerging field using electronic information that is routinely collected in various large administrative health databases. The Community Heart Outcomes Improvement and Cholesterol Education Study (CHOICES) will test the potential of using 'big data' in a 'real-world' clinical trial to measure outcomes using routinely collected health information. CHOICES aims to increase the use of cholesterol-lowering statin drugs to prevent heart attack and stroke in high-risk health regions across Ontario using a 'toolbox' of interventions. The 'toolbox' of interventions are informational strategies targeted for both patients and family physicians to help improve cholesterol management and contribute to shared decision making for heart healthy goals.
Associations between the built environment and health behaviours are robust, however (1) it remains unclear if the behaviours they elicit lead to meaningful improvements in health outcomes, at the population level and (2) little experimental evidence exists supporting these associations. The primary objective of this study is to capitalize on an urban natural experiment to determine if changing the built environment to support physical activity will (1) reduce the burden of CVD within a population and (2) if it's a cost-effective population intervention. An interrupted time series analysis will be performed over a period of 19 years to determine if the expansion of an urban trail network is associated with reductions in major advserse cardiovascular events (MACE) and CVD-related risk factors within a large urban centre in Canada.
Black individuals are more likely to have decreased insulin sensitivity which results in a high risk for the development of cardiometabolic disease. The reasons for this are incompletely understood. Natriuretic peptides (NPs) are hormones produced by the heart that play a role in regulating the metabolic health of an individual. Low circulating level of NPs is an important contributor to increased risk for diabetes. The NP levels are relatively lower among Black individuals thus affecting their metabolic health and putting them at a higher risk for diabetes. This study aims to test the hypothesis that by augmenting NP levels using sacubitril/valsartan, among Black Individuals one can improve their metabolic health (as measured by insulin sensitivity & energy expenditure) and help establish the role of NPs in the underlying mechanism behind increased risk for cardiometabolic disease in these population.
Our overall objective is to evaluate the efficacy of therapist-assisted, internet-based cognitive-behavioural therapy (iCBT) for depressed cardiac patients with respect to clinical outcomes, and the feasibility of the program. Our primary outcome will be depression severity; secondary outcomes will be hospitalization for a cardiac cause, recurrent myocardial infarction or revascularization. The study will inform a proposal to incorporate iCBT into the resources routinely available to cardiac patients following hospitalization for a cardiac event.
Although the impact of postmenopausal hormone therapy (HT) on cardiovascular disease risk has been studied in several large randomized trials, little is known about the acute cardiovascular consequences of HT discontinuation. In this randomized, double-blind, placebo-controlled trial, the investigators will compare the cardiovascular consequences of abrupt and tapered modes of HT discontinuation in 150 Finnish healthy postmenopausal women under age 60 years. The primary outcome is brachial artery flow-mediated dilatation. In addition, biochemical markers will be measured during the study period of 20 weeks. Health-related quality of life, frequency of hot flush recurrence and other menopausal symptoms will be also assessed in these groups. The trial will provide new high-quality information about the cardiovascular safety as well as the correct timing and method of HT discontinuation.
HD PCI is a multicenter, randomized, registry-based, cluster crossover design trial of higher dose versus lower dose heparin in patients undergoing elective percutaneous coronary intervention (PCI).
CARFARE (CARDIOMETABOLIC RISK FACTORS REGISTRY) is a registry done in the context of a cardiovascular primary prevention program of the Cardiometabolic Unit Officia of the Cardiology Department of the Austral University Hospital. The structured and sequential evaluation include measurement of anthropometric parameters (body mass index, BMI), laboratory with metabolic profile, baseline electrocardiogram, blood pressure (BP) measurement, arterial stiffness, subclinical atherosclerosis screening in the carotid and ileo-femoral territories using echo-doppler, echocardiogram, and ergometry test.
The objective of this research proposal is to find out whether comparing the two different anaesthetic maintenance techniques (Propofol vs volatile anaesthetics) in adult patients undergoing heart surgery is practical for the anaesthetist treating the patients and whether it is feasible for the research team to recruit patients and follow them up after the operation.
Liver fibrosis is the most important prognostic factor in patients with non-alcoholic factor disease. Clinical and biological condition, as diabetes or mutation for PNPLA3, are well known factors associated with liver fibrosis onset and progression. However, little is known about biochemical factors predicting liver fibrosis evolution in large NAFLD populations.
