A Study Assessing Repatha® in Combination With Standard of Care (SOC) Compared With SOC on Major Cardiovascular Events in Chinese Participants With Atherosclerotic Cardiovascular Disease

The primary objective of the study is to evaluate real-world effectiveness of treatment with Repatha® in combination with SOC, compared with SOC alone, on the risk for cardiovascular (CV) death, myocardial infarction (MI), stroke, hospitalization for unstable angina, or coronary revascularization, whichever occurs first, in participants with established atherosclerotic CV disease (ASCVD) treated with SOC, according to local clinical practice.

Relaxin Therapy for Atrial Fibrillation

Atrial fibrillation (AF) is the most common heart rhythm disorder. The presence of AF increases the risk of death and is associated with a 5-6-fold increase in stroke incidence, due almost exclusively to thrombus formation in the heart. Current therapies for AF are limited. The evaluation of new, more effective treatments for preventing AF recurrence remains a critical unmet clinical need. AF is considered a progressive disease that increases in prevalence with age and can convert from "paroxysmal" to "persistent" to "permanent" AF in a single individual. This progression results, in part, from high oxidative stress and progressive adverse electrical changes in the heart. Compelling preclinical and clinical data indicate that Relaxin, a naturally occurring peptide hormone, may reverse the electrical remodeling. Thus, our overall objective is to investigate the effects of Relaxin in Veterans who have failed medical management for symptomatic AF and is referred to Cardiac Electrophysiology Laboratory for catheter ablation and pulmonary vein isolation. We will determine whether Relaxin therapy, in addition to the standard of care, counteracts the oxidative stress-related electrical derangement and reduces the post-ablation AF burden. A unique aspect of this proposal is that it is based in part on observations derived from the basic, translational and computational labs of the PI and co-investigators and from the observations by the PI while caring for patients with AF. As such, this proposal represents a true progression from the bench to the bedside. If successful, our findings may lead to the design of a new, more effective treatment for a major unmet public health problem in the United States as well as the world.

The Effect of a Digital Heart Health App and Lifestyle Intervention for Heart Disease in Primary Care.

Despite the availability of medications, many people around the world continue to live with long-term health problems like heart disease, stroke and diabetes. In Canada, heart disease is a leading cause of death. Managing these health issues can be done by changing diet and lifestyle. Specific ways of eating have been proven to improve risk for heart disease and stroke. However, because doctors often have limited time, nutrition education, and lack of tools for counseling patients on nutrition, they can often only provide minimal support to help patients make necessary lifestyle changes. Digital tools and mobile applications offer an opportunity to involve doctors and patients in delivering nutrition interventions. This approach has the potential to save time, provide education, and reduce healthcare costs. This study is being done to understand the effect of a digital heart health program added to standard of care, compared with standard of care alone on heart health. All eligible participants in this study will be randomized (determined by chance) to one of two possible interventions: 1) a digital heart health program + standard of care; 2) standard of care. Standard is care is defined as the best practice based on guidelines for the treatment of a condition. All participants will be followed for seven years and will be asked to complete online questionnaires and complete blood work at their nearest LifeLabs clinic, as well as wear a continuous glucose monitor and wrist actigraph (at 3 time points in the first year). In addition, participants randomized to the digital heart health program + standard of care will be expected to use the heart health app and join 16 online synchronous sessions over the first year. After seven years, the intervention phase of the study will end and the study will become a cohort study. All participants at the 7-year time point will be invited to use the heart health app. As part of the cohort study, participants will be asked to continue completing the same questionnaires online and completing bloodwork at their nearest LifeLabs every four years for the duration of their participation in the cohort study. The main questions this study aims to answer are: 1. Will a digital heart health program added to standard of care result in a clinically meaningful reduction in blood cholesterol and other risk factors after 1-year compared to standard of care alone? 2. Will a digital heart health program added to standard of care result in a reduction in major cardiovascular events after 7-years compared to standard of care alone? 3. Are the observed effects sustained beyond the 7-years of the intervention? We hypothesize that the digital heart health program added to standard of care will result in a clinically meaningful reduction in blood cholesterol and other risk factors for heart disease after 1-year and reduce major cardiovascular events after 7-years compared to standard of care alone.

Use of Machine-learning Algorithms, Biomarkers and Measures of Quality of Life to Personalize Medical Management of Liver and Heart Transplant Recipients

This is an observational, low risk tissue based, non-pharmacological, retrospective-prospective study for adults heart and liver transplant patients, related to IRCCS Azienda Ospedaliero-Universitaria di Bologna (IRCCS AOUBO). This clinical study is part of the national multicentric project DARE. The project has the wide overarching aim to develop digital solutions for personalized healthcare.
