Artificial Intelligence Delivered Cardiac Magnetic Resonance - Prospective Validation
Cardiac MRI (CMR) scanning allows doctors to create detailed images of the heart. However, the need for experienced cardiac radiographers to perform each scan can make CMR's delivery difficult, and some patients in the UK wait more than half a year for a scan. These radiographers must take pictures of …
Association Between GalectiN-3 and POSt-operative AtrIal Fibrillation After Coronary Artery BypaSs Graft
The goal of this observational study is to test the association between high levels of Galectin-3 and the occurrence of post-operative atrial fibrillation after isolated coronary artery bypass grafting (CABG). The main question\[s\] it aims to answer are: Is Galectin-3 an accurate biomarker to predict higher risk of developing post-operative …
Adapting and Testing a Novel Digital Health Tool (PREVENT) to Improve Health Behavior Counseling and Cardiovascular Health in Rural Primary Care Clinics
The focus on this application is low-income, rural patients, since cardiovascular disease (CVD) prevalence is 40% higher among rural than urban residents. Health behavior counseling and follow-up care are required for patients with an elevated body mass index who have increased risk for CVD. Counseling is most effective when developed …
Single-tracer Multiparametric PET Imaging
The overarching goal of this project is to develop and evaluate a single-tracer multiparametric positron emission tomography (PET) imaging solution for simultaneous imaging of blood flow and glucose metabolism using 18F-fluorodeoxyglucose (FDG) alone. The investigators working hypothesis is that quantitative blood flow can be extracted from dynamic 18F-FDG PET data …
Plant Stanol Esters and Preventing Asthma Symptoms
Plant stanols are known to lower low-density lipoprotein cholesterol. However, studies have suggested that these compounds also influence the immune system. Asthmatic responses are predominantly T helper (Th)2 cell dependent, while plant stanols were previously found to activate Th1 cells and shift the immune response away from the Th2 cell …
Studying the Effects of Cannabis on Vasculature
Cannabis is commonly used globally. It is associated with psychiatric problems, but the effects on the cardiovascular system are unclear. In this project, the investigators plan to study the effects of cannabis on the cardiovascular system. This will be done by using a non-invasive test to measure blood vessel function …
Is Post-exertional Symptom Exacerbation Specific to Patients With Myalgic Encephalomyelitis / Chronic Fatigue Syndrome? A Study Comparing Patients With Myalgic Encephalomyelitis / Chronic Fatigue Syndrome and Patients With Cardiac Diseases Who Underwent an Exercise Test.
Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS) is a disease characterized by persistent and unexplained fatigue associated with diffuse pain, sleep disorders, neurocognitive and autonomic symptoms, musculoskeletal manifestations and digestive symptoms. A central feature of this disease is post-exertional symptom exacerbation, also referred to as post-exertional malaise, defined as the …
WISE CVD - Continuation (WISE HFpEF)
The Women's Ischemia Study Evaluation (WISE), a cohort study of over 1000 women, has made many contributions to the understanding of cardiovascular disease. A milestone acknowledged in the 2011 AHA Herrick Lecture is the role of Coronary Microvascular Dysfunction (CMD) in women with symptoms/signs of ischemia without obstructive coronary artery …
Inflammatory Resolution in Cardiometabolic Health and Disease
The specific aim of this study is to determine molecular pathways that differentiate metabolically healthy vs unhealthy human phenotypes, and to investigate the therapeutic potential of pro-resolving lipids. Investigators will recruit volunteers that are metabolically healthy or unhealthy that fall within three BMI ranges: lean (18.-24.9 kg/m2), overweight (25.0-29.9 kg/m2) …
Exercise Activity Intervention With Sensor-Based Engagement in Patients With Atrial Fibrillation
Atrial fibrillation (AF) affects 1 in 4 individuals during their lifetime and continues to increase in frequency and impact. Exercise intervention has established benefits to improve AF symptoms and burden in clinical studies. However, lack of access to exercise programs has limited therapeutic adoption. The growth of technology-driven health care …
