Filter by:Cardiovascular disease is the main cause of death worldwide. Endothelial dysfunction is the first step to development of cardiovascular diseases. Endothelial dysfunction occurs due to reduction in nitric oxide, a molecule that plays an important role on vascular health. Due to important role of nitric oxide in endothelial function, several studies have evaluated the effect of its precursors, such as L-citrulline and nitrate on endothelial function parameters. The present study will evaluate the effect of L-citrulline and nitrate derived by watermelon and beetroot products, respectively, on endothelial function of young and older participants. Furthermore, we will evaluate the plasmatic amino acids, nitrate, glucose and insulin in response to ingestion of these products.
Coronary heart disease (CHD) is a leading cause of premature death in Canadian women. Women who suffer an acute coronary event are more likely than men to be physically inactive, have lower exercise capacity, and die in the next year. The standard cardiac rehabilitation (CR) programs do not meet women's needs. There is a need to address these issues to increase participation in CR. The main purpose of this project is to evaluate the effects of high-intensity interval training (HIIT) compared to moderate-intensity continuous exercise training (MICE) on exercise capacity and quality of life in women with CHD. Positive results of this study will fill the gap in knowledge in exercise training, levels of motivation, self-efficacy and enjoyment following HIIT vs. MICE in women with CHD.
Patients with established cardiovascular disease (CVD) often have multiple medications that increase the risk of prevalence of drug therapy problems (DTP), subsequently leading to unfavourable clinical and health outcomes. By providing Comprehensive Medication Management (CMM) services to patients within a healthcare system, pharmacists assess patients' medication-related needs, identify and prevent DTP, develop individualized care plan for each individual patient and evaluate and monitor outcomes. Thus, the CMM services delivered at the primary care level in collaboration with general practitioners and other healthcare providers could address this problem and by optimizing therapy improve patients' clinical outcomes and quality of life. Studies have shown that patients with chronic diseases have the greatest benefit from the CMM services. The aim of this study is to evaluate the impact of CMM services on clinical and humanistic outcomes in patients with established CVD. The study will employ prospective, longitudinal, pre- and postintervention study with a 1-year patient follow-up.
The purpose of this project is to develop novel approaches to promote health and longevity while enhancing quality of life among persons with Sickle cell disease (SCD). Therefore, investigators are aiming to adapt an evidence-based exercise intervention for adults with SCD informed by culturally- relevant and biologic factors and pre-test the adapted exercise program in a small sample of adults with SCD.
The purpose of this randomized controlled pilot study is to test whether an in-hospital nurse-led smoking cessation intervention increases the refferal rate to healty life-centers in the municipalities. We will also describe the proportion who succeed in quitting smoking between the intervention group and the control group and obtain new knowledge about the patient and system factors of importance for participation to healty life-centers and for successful and unsuccessful smoking cessation.
Flaxseed and olive oil consumption have beneficial effects on cardiovascular risk factors. Nonetheless the effects of their simultaneous consumption have not yet been studied.The purpose of this study is to investigate the effects of a healthy diet containing flaxseed and olive oil compared with healthy dietary advice on cardiovascular disease risk markers in patients with coronary artery disease (CAD), in improving flow-mediated dilation, plasma lipid profile and fatty acids composition of red blood cells.
AIM: To advance the development and accuracy of the Lifelight® app for the measurement of vital signs, therefore developing a non-invasive and easy-to-perform means of measuring vital signs which can be implemented across a wide range of settings, both within hospitals and out in the community. METHOD: Lifelight® is a computer program ("app") for measuring vital signs which can be used on smart devices that contain a camera. It is able to measure all of the vital signs by measuring very small changes in skin colour that occur each time the heart beats. This means that it does not need to touch the patient. The investigators believe this could be an effective way of measuring vital signs, especially during the COVID-19 pandemic when prevention of cross-contamination between patients is essential. Patients are also likely to be reassured by a contactless approach. The app uses data from looking at a person's face to calculate the vital signs. This is possible because there are tiny changes in facial skin that occur each time the heart beats. The investigators believe Lifelight® could be an effective way of measuring vital signs. The app is still under development, which means that it is still "learning" the best match between the information it collects from the face and the values of vital signs measured using the standard equipment. The app should become more accurate in calculating the vital signs as it sees more and more information from patients. So far, the app has seen data from inpatients, outpatients, patients attending GP surgeries and healthy people. This has improved its accuracy in measuring vital signs. However, the app needs to see more information so that it can be sufficiently accurate for specific clinical applications such as long-term monitoring of hypertension. To do this, it particularly needs to see information from people with abnormal blood pressures and blood oxygen levels. In order to capture the full range of observations, the app will need to be trialled with some of the most critically ill patients - some of these will not have capacity to consent to participation in the study. It also needs to see more data from people with different skin tones so the investigators can be sure it is accurate for all patients. To do this, the investigators will recruit people who are attending one of two hospitals, either as an inpatient, an outpatient, a friend/relative of a patient, or a member of hospital staff. The exact number will depend on how quickly the app "learns" and how many of the vital signs are outside of the normal range. The investigators will take the participant's vital signs using standard clinical equipment whilst recording a video of their face. The investigators will use most of these measurements and video to teach the app how to become more accurate at measuring vital signs. The investigators will keep the remaining data separate and use it to test how accurate the app is. All of the data will be kept securely. The investigators will also collect feedback from participants and healthcare staff on their experiences using the app and information that allows us to assess whether there are any savings to the healthcare economy through use of this technology.
Device: EluNIR Ridaforolimus Eluting Coronary Stent System - (hereafter referred to as EluNIR) 2.25 mm diameter (8 mm, 12 mm, 15 mm, 17 mm, 20 mm, 24 mm, 28 mm and 33 mm length) Objectives: To further assess the safety and efficacy of the small diameter (2.25 mm) Ridaforolimus Eluting Stent - EluNIR. Subject Population: Subjects who underwent PCI for angina (stable or unstable), silent ischemia (in absence of symptoms a visually estimated target lesion diameter stenosis of ≥70%, a positive non-invasive stress test, or FFR ≤0.80 must be present), NSTEMI, and recent STEMI (>24 hours from initial presentation and stable) with attempted implantation of a 2.25 mm diameter EluNIR stent. Trial Design and Methods: This is a prospective, multi-center, single-arm, open-label clinical trial. Clinical follow-up for all patients will be performed at 30 days 6 months, and 1 year after the procedure.
The purpose of this multi-center, double-blinded pilot study is to determine if extra virgin olive oil (EVOO) has a positive effect on HDL cholesterol levels and anti-inflammatory markers for subjects diagnosed with cardiovascular disease (CVD) and to determine if the polyphenol concentration is proportional to those effects. Subjects will complete consecutive 28-day periods (with a 14-day washout between) in which they will either consume the low polyphenol concentration EVOO daily or the high polyphenol concentration EVOO. In a double-blinded manner, each subject will be his or her own control with a 14-day washout between study periods. HDL levels and other parameters will be measured after each period of the protocol. The investigators anticipate HDL levels will improve with both olive oils. The investigators expect the high polyphenol concentration EVOO will show a greater effect than the EVOO with a low polyphenol concentration. EVOO with high polyphenol concentration may be a simple method to reduce the risk of secondary CVD events.
In the electronic Framingham Heart Study (eFHS), the investigators developed and deployed a mobile app to collect cardiovascular risk factors and event data and test them against cardiovascular data collected in the Framingham research clinic for the FHS. Participants enrolled in eFHS receive a series of digital surveys modules to complete on a regularly occurring schedule. The objective of the planned randomized trial is to test the effect of administering half of survey modules every 2 weeks versus all survey modules every 4 weeks on improving participants' response rates. There will be 4 survey periods. Period 1 encompasses all survey modules administered from baseline up to week 8 (19 surveys/tasks per participant); period 2 from week 8 up to week 16 (18 surveys/tasks per participant); period 3 from week 16 up to week 24; period 4 from week 24 (16 surveys/tasks per participant).
