Cardiovascular Risk Factor

Vascular risk factors drive stroke, heart disease, and dementia, but translating lifestyle guidelines into routine clinical care remains challenging. To address this, we developed the BASIC-S framework, targeting Blood pressure, Activity, Sleep, Interaction (socially), Consumption (nutrition), and Support using partner support and motivational interviewing. This individual-focused approach bypasses the logistical and financial barriers of complex clinical interventions by using sustained behavioral science to support gradual lifestyle changes. This study is a single-center, mixed-methods, cluster-randomized pilot trial evaluating the feasibility of the BASIC-S protocol in an occupational setting. A maximum of 60 households (120 participants) will be randomized 1:1 to either the BASIC-S intervention (motivational coaching, secure video check-ins, automated text messages, and a digital workbook) or standard care. Outcomes will assess feasibility, acceptability, and the validity of new tracking metrics to inform a future full-scale trial.

This is a cross-sectional study with an optional intervention that will examine how extreme sleep durations relate to cardiovascular health, physical activity, and sleep quality by studying three groups of participants: short sleepers (≤ 6 hrs), long sleepers (≥ 9 hrs), and average duration sleepers (7-8 hrs). The optional intervention asks participants to maintain an 8-hour per night regular sleep schedule for one week.

This exploratory pilot randomized controlled trial evaluates whether a HeartMate application-based remote patient monitoring (RPM) and digital cardiac rehabilitation program improves cardiovascular, functional, and psychological outcomes in patients with cardiac disease. A total of 200 participants with cardiovascluar disease requiring rehabilitation are randomly assigned in a 1:1 ratio to an intervention group or a control group. The intervention group uses the HeartMate app-based remote cardiac rehabilitation program for 6 weeks, including a daily heart check using smartphone remote photoplethysmography (rPPG), aerobic and resistance exercise, breathing training, and a cognitive-behavioral 'mind' program, with weekly remote coaching. The control group receives usual outpatient care and lifestyle education materials, with the app installed only for rPPG measurement so that digital-biomarker measurement is identical across groups. Clinical assessments (6-minute walk distance, grip strength, blood pressure, blood lipids and metabolic markers), questionnaires (SF-12, PHQ-9, GAD-7, KOSS-24), and digital biomarkers (rPPG-derived heart rate, heart rate variability, respiration, activity) are collected at baseline and at 6 weeks. The primary outcome is the between-group difference in the change in 6-minute walk distance from baseline to 6 weeks. Because this is an exploratory pilot, the results are intended to estimate the effect size and variance for a future definitive randomized controlled trial, and to assess the validity of digital biomarkers as well as the safety, feasibility, and adherence of the program.

Our group has recently identified the association between gut-flora-mediated carnitine and phosphatidylcholine metabolism, specifically trimethylamine-N-oxide (TMAO), and cardiovascular risk. This study investigates the ability for dietary intervention to modulate TMAO levels.

This project will examine the diagnosis and prognosis of patients with cardiovascular disease in hospital in- and outpatients and compare their characteristics with normal controls from the community. The cardiovascular diseases studied include coronary artery disease, heart failure, heart attacks, valve disease, cardiac surgery, dysrhythmias, aneurysms, embolism, strokes, peripheral vascular disease and hypertension. Current methods for diagnosis and predicting outcome in patients are limited and may lack accuracy. This study will collect clinical details, and blood and urine samples from patients for analysis of proteins, chemicals and genetic biomarkers which will enable an examination of the pathological mechanisms involved in cardiovascular disease. The data will also be used to improve diagnosis and also improve prediction of outcome in patients (future clinical events such as death, further hospitalisation with cardiovascular disease and the effects of any therapy given to the patients). In this way, we can develop accurate ways of assessing a patient's condition and how it could be effectively managed. The study will last for 20 years.

Americans continue to consume high amounts of sodium. Potassium is notable for its blood pressure lowering effects but less is known regarding its effect on the vasculature. This investigation seeks to determine the role of dietary potassium on the vasculature in the presence of a high sodium diet in salt-resistant adults.

In this single-center, longitudinal observational study, we will comprehensively examine clinical characteristics, proteomic, metabolomic, genomic and imaging data to better understand how different heart failure types may develop and progress over time. We will evaluate distinct sub-groups of heart failure (also known as heart failure phenotypes) and cardiomyopathies including amyloidosis with an ultimate goal of bringing the right medications and therapy to the right patients to optimize benefit and minimized side effects, an effort to improve precision medicine in heart failure.

This randomized, open-label clinical trial will evaluate whether adding fostemsavir to current antiretroviral therapy can reduce the risk of cardiovascular disease in people with well-controlled HIV. Researchers will compare imaging, clinical and biomarker outcomes between participants who receive fostemsavir in addition to their existing treatment and those who continue with standard care alone.

In health, blood pressure (BP) falls at night by \>10% compared with day-time values. This natural dipping pattern is important as without it there is an increased risk of cardiovascular disease (CVD). Recent evidence suggests that chronotherapy (taking anti-hypertensive medication at bedtime instead of in the morning) may enhance nocturnal BP dipping and reduce the risk of CVD events. There is therefore an urgent need to characterise diurnal BP patterns in patients who may be at risk of reduced nocturnal dipping in order to maximise protective therapy in all those who would benefit. Similarly, it has previously been demonstrated that increased arterial stiffness is associated with increased CVD risk, however little is known about whether loss of diurnal variations in arterial stiffness confer addition risk. Kidney disease is independently associated with increased CVD events, but the exact makeup of this risk is not clear. Within this heterogenous cohort several very distinct groups exist including those with acute kidney injury (AKI), chronic kidney disease (CKD), inflammatory conditions like small vessel vasculitis (SVV), and those who have either donated or received a kidney transplant. Diurnal BP and arterial stiffness patterns within these patient groups are not well characterised. The investigators will recruit patients at increased risk of CVD from the Royal Infirmary of Edinburgh Renal and Vasculitis Clinics. Participants will undergo 24-hour ambulatory BP and arterial stiffness measurement in conjunction with day- and night-time blood and urine sampling on two separate occasions. This study aims to characterise diurnal patterns of BP and arterial stiffness in patients at increased risk of CVD and compare findings with healthy controls. In doing so, the investigators aim to allow more targeted CVD risk reduction strategies and improve long-term patient outcomes.

In a prospective cohort study (n = 1.000), the investigators aim to investigate the correlation between cardiac biomarkers and advanced echocardiography and determine whether these are prognostic markers of heart disease in patients suffering from psoriasis.

The goal of this clinical trial is to learn if "prescribing" afterschool care to children at risk for poor heart health later in life increases their physical activity and improves their heart health. 'Prescriptions' will be provided by pediatricians at participating Federally Qualified Health Centers and vouchers to existing afterschool programs (e.g., YMCA, Boys and Girls Clubs) will be provided by the research study. The main questions this study aims to answer are: Can afterschool care providers and health care providers easily offer and keep using the voucher program? Will families use the voucher? Do they go to afterschool care regularly, and do the families who use them represent a wide range or backgrounds? Does going to afterschool care help children be more physical activity? Does going to afterschool care improve heart health? Researchers will compare two randomly assigned time periods; one semester when families get the voucher and one semester where they do not. They will look at whether use of the afterschool care voucher leads to more physical activity and improved heart health.

Current approaches in primary prevention for cardiovascular disease are based on probabilistic approaches to estimate risk, using many of the widely available cardiovascular risks scores, with over 100 such scoring systems currently available throughout the world. The rationale for this practice is to select those individuals at greatest risk for more intense targets, reduce risk of treatment to those at minimal risk, and to maximize the cost-effectiveness of treatment. A recent Cochrane Systematic Review assessed the practice of using risk scores to select individuals for the primary prevention of cardiovascular disease. 3 The principal finding of the systematic review was that there was little or no effect of providing clinicians with cardiovascular risk scores when compared to standard of care (5.4% versus 5.3%; relative risk 1.01, 95% confidence intervals 0.95 to 1.08). The authors concluded that there is major uncertainty whether current strategies for providing risk scores and called for further research to address this concern. Extent of coronary artery calcium (CAC) is a strong risk marker for coronary events, with evidence mainly derived from observational studies and from prospective non-randomized studies. CAC, although endorsed for intermediate risk patients, is not widely adopted due to barriers in reimbursement. The cost of the test ranges between 100 and 300 USD in the United States, which may have limited the wide adoption of the test. Whether reducing the cost burden for CAC increases utilization for routine screening and its influence on physician practices and downstream testing is largely unknown. University Hospitals started offering low charge CAC (99$) since 2014. In 2017, University Hospitals started offering CAC for no charge for patients to improve access to this test, which has not traditionally been covered by insurance companies. The impact of no-charge CAC has never been studied.

The regular consumption of seaweed, as observed in Japan, is associated to a reduced cardiovascular risk and prolonged life expectancy. Interventional studies have shown that brown seaweed consumption can reduce blood pressure, improve glycaemic control and lipoprotein profiles, although this varies with population, dose, duration and the type of seaweed. Brown seaweed appears the most promising to improve cardiovascular risk, due to the presence of specific antioxidants (polyphenols called phlorotannins), pigments (fucoxanthin) and fibre (alginate, fucoidan). Women see their cardiovascular risk greatly increased when they reach menopause, and seaweed consumption may provide benefits for this population. In the UK, 98% of UK residents drink tea daily (Source UKTIA), with English breakfast tea being the most popular. Providing a tea enriched with beneficial compounds has the potential to improve cardiovascular health in a wide range of the population, including postmenopausal women. Abertay university (Dundee, UK) has recently developed an English Breakfast tea enriched with fermented seaweed, which was found to taste like English breakfast tea. We hypothesise that the consumption of 3 cups a day of the Abertay-developed Tea (AberTea) for 8 weeks, with each tea bag containing 1g of fermented seaweed, will improve vascular function and cardiovascular risk factors in postmenopausal women.

The goal of this longitudinal study is to investigate the role of virtual health coaching on mitigation of cardiometabolic disease risk in an underserved, food insecure population. The main questions it aims to answer are: * Does longitudinal, individualized health coaching directed at lifestyle modification reduce patient 10-year risk of heart attack or stroke? * Does longitudinal, individualized health coaching directed at lifestyle modification reduce rates of hypertension, hyperlipidemia, and diabetes? * Does longitudinal, individualized health coaching directed at lifestyle modification improve accessibility to healthcare? Researchers will investigate the effects of regularly scheduled health coaching sessions on composite cardiometabolic risk profile as well as individual modifiable cardiovascular risk factors. Participants will: * Participate in in-person cardiovascular screening, occuring at the time of enrollment, months 3 and 6. * Engage in virtual health coaching sessions to talk about diet, exercise, weight loss, blood pressure and diabetes control, and accessibility to healthcare * Keep a log of their blood pressure

Lowering of blood pressure (BP) in high-risk hypertensive individuals reduces major adverse cardiovascular and cerebrovascular events. Diabetic patients with hypertension benefit from BP lowering treatment. The present trial, IPAD in brief, is a randomized, open-label, parallel-designed, multicenter study involving nearly 12,000 patients to be recruited and to be followed up for a median of four years. IPAD tests the hypothesis that antihypertensive medications in adults with type 2 diabetes, whose seated BP 120-139 mm Hg systolic and below 90 mm Hg diastolic, results in 20% difference in the incidence of major adverse cardiovascular and cerebrovascular events. During follow-up for participants in the intensive group, the sitting systolic pressure should be decreased to below 120 mm Hg, by titration and combination of the study medications of an angiotensin type-1 receptor blocker Allisartan (240 mg/day), a dihydropyridine calcium-channel blocker (amlodipine 5-10 mg/day), and/or other medications if necessary. For those in the standard group, the sitting systolic pressure should be monitored and controlled below 140 mm Hg.

The ACTIONcardioRisk trial is designed to investigate the effect of aerobic and progressive resistance training exercises combined with cognitive training, on neurocognitive functioning of sedentary older adults with and without cardiovascular risk factors.

This study will look at how well a drug that reduced the amount of oxalate in the body works in patients that have kidney disease and need dialysis treatment. People with kidney disease often have higher levels of oxalate in the blood. People with kidney disease are also at higher risk of having heart attacks, heart disease and strokes (these are called cardiovascular diseases). It is thought that high oxalate levels may increase the risk of these diseases. This study will investigate if this medicine can lower the amount of oxalate in the blood of dialysis patients and see if there is any change in the health of their heart. This medicine is already used for people who have high oxalate levels because of a genetic cause and has been used safely for patients on dialysis. The study will put the participants randomly into either the group getting the study medicine or the group getting a placebo (this will be a solution of saline water). Neither participants not the doctors will know whether the drug or placebo is given until after the end of the study. At the start of the study all the participants will have an echocardiogram (an ultrasound of the heart) and again 6 months later at the end of the study. We will also take blood tests once a month when the participants come for dialysis.

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 goal of this observational study is to define a personalized risk model in the super healthy and homogeneous population of Italian Air Force high-performance pilots. This peculiar cohort conducts dynamic activities in an extreme environment, compared to a population of military people not involved in flight activity. The study integrates the analyses of biological samples (urine, blood, and saliva), clinical records, and occupational data collected at different time points and analyzed by omic-based approaches supported by Artificial Intelligence. Data resulting from the study will clarify many etiopathological mechanisms of diseases, allowing the creation of a model of analyses that can be extended to the civilian population and patient cohorts for the potentiation of precision and preventive medicine.

The main objective of this study is to test the ability of novel cardiovascular disease (CVD) prognostic tools to identify women at risk for future CVD. We plan to establish a cardiovascular health screening program at the St. Boniface Hospital and to test the efficacy of these tests for predicting adverse cardiovascular outcomes amongst a cohort of 1000 Manitoban women aged 55 years and older in the 5-year period after screening. A second purpose of this project is to identify novel CVD biomarkers that may indicate a person is at risk for cardiovascular disease. Therefore, we plan to ask participants for permission to collect and store a sample of both their blood and stool for future research.

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.
