GENESIS: Genotype Guided - Natriuretic Peptides - Cardiometabolic Health Study
Natriuretic Peptides (NP) are hormones produced by the heart, and they have a wide range of favorable metabolic benefits. Lower levels of these hormones are associated with an increased likelihood of the development of diabetes and poor cardiometabolic health. Obese and Black individuals have \~30% lower levels of NP and are at a greater risk of developing cardiovascular (CV) events as compared to lean and White counterparts. Some people have common genetic variations that cause them to have \~20% lower NP levels. Similar to other low NP populations, these individuals with low NP genotype (i.e., carrying a common genetic variation called rs5068) are at a greater risk of developing cardiometabolic diseases. By understanding the NP response following the exercise challenge and the glucose challenge in individuals with genetically lower NP levels will help us understand how to improve cardiometabolic health in them.

PRECISION-BP: Precision Chronopharamacotherapy Targeting NP-RAAS-BP Rhythm Axis
Obese individuals have a higher prevalence of nocturnal hypertension and non-dipping blood pressure (BP). These conditions are associated with an increased risk of cardiovascular (CV) events and death. Natriuretic Peptides (NPs) are hormones produced by the heart which directly regulate BP by causing dilation of blood vessels and by removing sodium and water from the body. NPs have a 24-hour day-night rhythm and this controls the day-night rhythm of BP as well. The NP-BP rhythm relationship is broken down in obese individuals. Obese individuals also have lower circulating NP levels. Lower circulating levels of NPs and elevated renin hormone (a part of the Renin-Angiotensin-Aldosterone System \[RAAS\]) at nighttime may contribute to the high nocturnal blood pressure in obese individuals which puts them at a higher risk of developing CV events. This current study seeks to determine the biological implications of chronopharmacology for synchronizing NP-RAAS-based blood pressure therapy with the physiological diurnal rhythms to restore the normal diurnal rhythm of blood pressure in obese individuals.

Smartphone Twelve-Lead ECG Utility In ST-Elevation Myocardial Infarction II
AliveCor (www.alivecor.com) has developed several electrocardiogram (ECG) devices that interface with iOS and Android smartphones and tablets via various Kardia apps. The current Kardia family of devices can measure single lead and six limb-lead ECGs, depending on the device. KardiaMobile, KardiaMobile 6L, and KardiaMobile Card have FDA clearance for ECG rhythm recording. A modified single-lead Kardia smartphone 12-lead ECG was previously validated in the multicenter ST LEUIS study for the diagnosis of ST-Segment Elevation Myocardial Infarction (STEMI) and Non-ST-Elevation Myocardial Infarction (NSTEMI). Recently, AliveCor developed a new device: AliveCor (AC) 12-lead (12L) ECG System to record simultaneously 4 leads of ECG and then generate complete 12-lead ECGs. A previous protocol at the University of Oklahoma involved 200 subjects with early prototypes of the AC 12L device with the specific aim to validate that it accurately generated 12-lead ECGs as compared to simultaneously acquired FDA-cleared 12-lead ECGs. The prototype version of the AliveCor 12L ECG System simultaneously measured four channels of ECG (leads I, II, V2, V4), calculated the remaining limb leads as is standard for 12-lead ECGs (Leads III, aVR, aVL, aVF) and synthesized the remaining 4 precordial ECG leads (V1, V3, V5, V6). This protocol will serve to validate the production version of the system against standard 12-Lead ECGs for the diagnosis of STEMI and NSTEMI in patients admitted to the Emergency Department or directly to the Cardiac Cath Lab for the evaluation of chest pain. It is anticipated that the waveforms for each of the 12 leads from the AC 12L ECG System will be highly correlated with the corresponding leads from the comparator commercially available 12-lead ECG devices used at participating sites. The purpose of this study is to clinically validate that the four-channel AC 12L ECG device can enable the diagnosis of STEMI and NSTEMI in a non-inferior manner to existing 12-lead ECG devices.

Effect of infLuenza vaccInation After Myocardial INfArction on Cardiac inflammaTory responsE
The goal of this randomized, double-blind, placebo-controlled clinical trial is to investigate the immunological effects of influenza vaccination outside of the influenza season on arterial inflammation in patients with a recent acute myocardial infarction (AMI). The primary objective is to compare the effects of influenza vaccination to those of a placebo in reducing post-myocardial infarction coronary inflammation as measured by coronary computed tomography angiography (CCTA). The main questions it aims to answer are: Does influenza vaccination reduce arterial inflammation as measured by CCTA at week 8 after percutaneous coronary intervention (PCI) in comparison to baseline? Does influenza vaccination modulate systemic inflammation as measured by blood biomarkers and in-vitro challenge tests at week 8 after PCI in comparison to baseline? Researchers will compare the effects of influenza vaccination with those of a placebo.

Virtual Care Strategies to Improve Participation in Cardiac Rehabilitation Among Veterans
Home-based CR (HBCR) is an alternative to traditional CR programs that has comparable efficacy in improving morbidity/mortality and increases access to critical services. There is major potential to improve Veteran engagement in CR by combining digital coaching (d-Coaching) with existing VA-supported technologies. The investigator's theory-based intervention targets a critical component of successful CR engagement that is not available through traditional programs: virtual social support through a social network. In addition, the investigators propose to improve self-efficacy and self-regulation through interactive digital multi-media education, personalized feedback, and motivation so that Veterans can complete the prescribed HBCR program and maintain physical activity long-term. This RCT will evaluate the effects of HBCR alone (usual care) versus HBCR + d-Coaching, including a private group with direct messaging on the Connecteam mobile application and bimonthly engagement sessions via VA Video Connect. The investigators will randomly assign 150 Veterans from 2 HBCR programs to a 3-month intervention. The addition of d- Coaching to existing digital technologies will be operationalized by using a private social media group to provide social support, education, personalized feedback, and motivation. The investigators aim to determine the effect of the d-Coaching intervention on: a) the number of completed HBCR sessions over 3 months, b) functional capacity, c) physical activity, c) psychosocial outcomes, d) clinical outcomes, and e) social cognitive factors of self-efficacy, self-regulation, and perceived social support over 6 months. The investigators will also evaluate the extent to which self-efficacy, self-regulation, and perceived social support mediate the effect of the intervention on function and physical activity.

Respiratory and Cardiovascular Alterations in Patients With Chronic Obstructive Pulmonary Disease
Chronic obstructive pulmonary disease (COPD) is a lung condition characterized by chronic respiratory symptoms (dyspnoea, cough, sputum production and/or exacerbations) due to abnormalities of the airways (e.g. bronchitis, bronchiolitis) and/or alveoli (emphysema) that lead to persistent, often progressive, airflow obstruction. It is a major cause of disability and death worldwide. Moreover, people with COPD often have cardiovascular diseases (CVDs) that are associated with increased risk for hospitalization and prolonged stay as well as all-cause and CVD-related mortality. Nevertheless, CVDs in patients with COPD are tend to be underestimated in clinical practice. Mechanisms that define the relation between COPD and cardiovascular morbidity include lung hyperinflation, hypoxia, pulmonary hypertension, systemic inflammation and oxidative stress, exacerbation, shared risk factors and COPD phenotypes. In the past years, some authors have announced that COPD treatment with dual bronchodilation may not only improve pulmonary function and quality of life, but also have a positive effect on cardiac function. However, there is a lack of studies with treatment-naïve patients that would describe the initial effect of dual bronchodilation on respiratory and cardiovascular systems. In this study we aimed to evaluate the effect of initial dual bronchodilation on the quality of life, respiratory and cardiovascular systems in patients with newly-diagnosed chronic obstructive pulmonary disease.

EASi-PROTKT™ - A Study to Test Vicadrostat (BI 690517) Taken Together With Empagliflozin in People With Type 2 Diabetes, High Blood Pressure, and Cardiovascular Disease
This study is open to adults with type 2 diabetes, high blood pressure, and cardiovascular disease. People can join the study if they have these conditions and do not have a history of heart failure. The purpose of this study is to find out if a medicine called vicadrostat, when taken with empagliflozin, helps reduce cardiovascular risk in people with these conditions. The study will compare this combination to a placebo version of vicadrostat with empagliflozin. Participants are put into 2 groups randomly, which means by chance. One group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets with empagliflozin. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants take a tablet once per day for 2 and a half years and up to 4 years and 3 months. All participants also continue their medication for type 2 diabetes, high blood pressure, and cardiovascular disease. Participants have an equal chance of receiving the study medicine or placebo. Participants are in the study for up to 4 years and 3 months. During this time, they visit the study site regularly. During these visits, doctors collect information about participants' health and take blood samples. The doctors document when participants experience cardiovascular events. The doctors also regularly check participants' health and take note of any unwanted effects.

BEhavioral and Adherence Model for Improving Quality, Health Outcomes and Cost-Effectiveness of healthcaRe
Lack of adherence to treatment is a widespread issue worldwide, which leads to higher healthcare utilisation rates and even premature death. While the level of adherence may differ based on the specific condition and treatment, studies estimate that approximately 50% of medications are not taken according to the prescribed instructions. In addition, adherence rates tend to decrease even further when the treatment requires a behavioural change. Literature reviews about factors that affect people's adherence show that it is challenging to predict whom can be considered to have adherent and non-adherent behaviours. In addition, the studies highlight that it is challenging to support a person to be adherent. Based on this knowledge the BEAMER project was established (Behavioural and Adherence Model for improving quality, health outcomes and cost-Effectiveness of healthcaRe). The overall goal of the project is to improve the quality of life of individuals, enhance healthcare accessibility and sustainability, thereby transforming the way healthcare stakeholders engage with patients to understand their condition and adherence levels throughout their healthcare journey. To address the overall goal, the BEAMER project has developed a disease agnostic model named "B-COMPASS: BEAMER-COmputational Model for Patient Adherence and Support Solutions". The aim of the B-COMPASS is to identify patients' needs and preferences which enables the creation of patient-specific supports, with the intention of improving their adherence to treatment within the heterogeneity of the different disease-areas and healthcare contexts. Based on the validated BEAMER questionnaire, the B-COMPASS predicts relative adherence and offers an elicitation process of patient needs and preferences to enable targeted supports to improve patient adherence. This results in an allocation of patients to different groups based on their needs and preferences. Overall, the B-COMPASS provides patient insights that will enable more effective design of patient support, most likely resulting in better patient experience, improved adherence and lower healthcare and societal costs. So far, several activities from a technical and user perspective have already been conducted in the project to refine the B-COMPASS. This has been done by applying an iterative mixed method approach were both stakeholders (regulator, pharma, academic/research and small and medium-sized enterprises) and end users (patients, health providers and health systems) have been involved. Despite the finetuning of the B-COMPASS, the effectiveness of the B-COMPASS hinges on empirical investigations into the structural elements that impact patient behaviour and the identification of predictive factors that can assist healthcare providers' (HCP) and Research Leads in designing more effective treatment plans (the term HCPs/Research Lead include both the individuals and the institutions where care is delivered). Therefore, validation studies will be conducted to assess the B-COMPASS's performance in six therapeutic areas (cardiovascular, endocrinology, immunology, neurology, oncology and rare diseases) with patients recruited in at least Italy (FISM), Portugal (APDP and MEDIDA) Norway (AHUS), Spain (FHUNJ and FIIBAP), The Netherlands (WDO), and Germany (UDUS). The collected data will be used to evaluate the B-COMPASS's capacity to attend to a variety of needs and challenges for adherence.

Stress Reactivity and Mother-Infant Cardiovascular Disease Risk
Prenatal Mindfulness training (MT) shows promise as a preventive intervention against hypertensive disorders of pregnancy (HDP) and may reduce risk for offspring cardiovascular disease (CVD). One proposed mechanism of MT to reduced CVD risk is improved self-regulation following stress. Perhaps the most crucial contributor to the development of self-regulation in the first year is the psychophysiological coregulatory relationship between mother and infant. However, this self-and co-regulation among women exposed to prenatal MT has not been studied and has yet to be examined in relation to CVD risk. The goal of this proposed project is to evaluate maternal-infant physiological reactivity to and recovery from stress at 6 months postpartum following prenatal MT, and to examine the relationship between these maternal infant stress responses and maternal-infant CVD risk at 12 months postpartum. Using a lab-based stress paradigm and well-validated biomarkers of mother and infant CVD risk, the investigators will assess respiratory sinus arrhythmia and heart rate at 6 months postpartum for 40 mother-infant dyads who have completed either prenatal MT or a usual care arm of an RCT examining MT for women at risk for HDP. The investigators will compare maternal, infant, and dyadic stress responses by treatment arm. Then, cardiac stress responses will be examined as predictors of maternal and infant biomarkers of CVD risk at 12 months postpartum.

Lung Cancer Prevention Screening Programme in Italy
This prospective randomized multicentered clinical study aims at implementing early diagnosis of lung cancer in high-risk heavy smokers in the Italian population. The main goal of the study is to develop a nationwide lung cancer prevention screening with high quality standard, similar to that of other screening programs i.e. breast, colon and cervix ongoing in Italy. The Italian Pulmonary Screening Network (RISP) includes 18 centers, which will promote primary prevention by offering a smoking cessation program (i.e. counselling and anti-smoking cytisine-based therapy) and secondary prevention by screening volunteers with chest Low Dose Computed Tomography (LDCT). The primary objective of the study is to demonstrate the non-inferiority of a risk-based screening strategy (less intensive, every 2 years) compared to the standard annual screening, in terms of stage I/II lung cancer incidence. Furthermore, the study aims to provide evidence whether blood biomarkers screening intervals can improve the efficiency of lung cancer screening by requiring less CT examinations while retaining the ability to diagnose lung cancer at curative state.

Optimal Blood Pressure for the prevenTIon of Major vAscuLar Events in Patients With DIABETES Mellitus (OPTIMAL-DIABETES)
High blood pressure (BP) is a major public health concern, especially in low and middle income countries. High BP is a highly prevalent condition, and it is usually associated with diabetes mellitus. Both high BP and diabetes are risk factors for major cardiovascular events including cardiovascular death, acute myocardial infarction, stroke, unstable angina and heart failure. In addition, high BP is also related to cognitive decline. The OPTIMAL-DIABETES trial consists of a two-arm, multicenter, randomized clinical trial designed to test whether a lower systolic blood pressure (SBP) target will reduce the occurrence of major cardiovascular events in diabetic patients compared to the standard SBP target.

Defining the Genetics, Biomarkers and Outcomes for Dilated Cardiomyopathy
Finding new ways to diagnose and treat Dilated Cardiomyopathy (DCM) could improve the health and well-being of patients with this condition. The main aim of this research study is to help develop better ways of diagnosing and treating patients with DCM. The information that is collected may help develop tailored treatments for patients with this disease in the future. This research study will recruit patients with DCM from a number of centres across England and follow their health over a period of years. Patients will give some blood samples for a type of genetic test called whole genome sequencing (WGS) to look for genetic changes. Patients will also have a magnetic resonance imaging (MRI) scan of their heart to look for any changes in the heart such as scarring, and check their heart function. The aim of this study is to discover if using WGS and MRI can improve the diagnosis of DCM. Another aim of the study is to look at how genetic changes and scarring in the heart may affect the progress of the disease. Studying patients with DCM may also help the investigators learn more about diagnosing and treating other diseases of the heart. The second aim of this study is to see whether using WGS and MRI scanning can also be useful in other types of heart diseases which might be affected by genetic changes or scarring in the heart.

The Leadless AV Versus DDD Pacing Study
Cardiac pacemaker (PM) implantation is the established treatment for relevant bradyarrhythmias. Conventional PMs require 1-3 pacing leads to register the heart's intrinsic activity ("sensing") and to deliver the electrical stimuli to the heart ("pacing"). These leads are responsible for the vast majority of morbidity after implantation and PM failures. Therefore, a leadless PM system (Micra TPS™, Medtronic, United States) has been introduced a few years ago. This system overcomes the limitations of leads, however, the first generation of the Micra TPS™ only allowed sensing and pacing in the right ventricle. More recently, an upgraded version has been introduced and gained market approval (Micra AV, Medtronic, United States). According to published results from several clinical trials, this device allows sensing the atrial activity and, thus, timing the delivery of the ventricular pacing impulse in a physiological manner similar to a conventional dual-chamber PM with two leads. Clinical feasibility and safety for this concept have been established already. However, it is unclear if this translates into a direct clinical benefit for patients in comparison to conventional PM systems. The aim of this trial is to compare the therapeutic efficacy of the Micra AV™ PM and conventional dual-chamber PM systems in patients with intermittent or permanent atrioventricular conduction block and a PM indication according to the latest European guidelines. Thus, patients will be randomized to either a conventional dual-chamber PM implantation or the implantation of a leadless Micra AV™ system. Patients will be stratified for gender (female/male) and a priori estimated physical exercise capacity ("fit"/"unfit"). The primary outcome will be the physical exercise capacity of the patients. The null hypothesis with regards to the primary endpoint is that the leadless pacemaker arm shows an inferior VO2 anaerobic threshold than the conventional pacemaker arm. Hence the alternative hypothesis postulates that the leadless pacemaker arm shows a non-inferior VO2 anaerobic threshold compared to the conventional pacemaker arm. Rejection of the null hypothesis is needed to conclude non-inferiority.

Using Big Data to Conduct Innovative Cardiovascular Clinical Trials
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.

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 worsening or the appearance of symptoms after physical or mental exertion, sometimes even minimal. Several studies have described post-exertional malaise in populations of patients with ME/CFS following a standardized exercise test performed over one or two consecutive days. These studies confirmed the presence of post-exertional malaise in ME/CFS patients compared with healthy controls or patients with multiple sclerosis. However, no data are available evaluating the impact of an exercise test on symptoms in patients referred to cardiology for this examination. Patients with cardiac diseases may also present symptoms such as fatigue, dyspnea or exercise intolerance. This study aims to compare post-exertional symptoms in two populations: patients with ME/CFS and patients with cardiac diseases undergoing an exercise test as part of routine clinical evaluation. The study also aims to measure variations in muscle oxyhemoglobin and deoxyhemoglobin concentrations before, during and after exercise using Near Infrared Spectroscopy (NIRS).

Penn Medicine Biobank Return of Results Program
The goal of this hybrid type 1 effectiveness-implementation study is to evaluate and compare different ways of delivering genetic research results to participants. The main questions the study aims to answer are: * Is sharing actionable genetic research results with participants through a multimedia patient-informed eHealth intervention (e.g. patient portal) no worse than sharing results by telephone or videoconference with a genetic counselor? * Will research participants access an eHealth educational intervention or chatbot education to learn about research results being offered and the option to decline learning their individual research results and how frequently participants choose to decline actionable research results? * Who benefits less and more from digital intervention with return of actionable research results and what barriers exist to using these tools for return of research results outside this study? Participants in the biobank will be offered digital tools to learn about research results being offered and the option to decline receiving these results. Those who don't decline and have an actionable result will be randomly assigned to receive their results with a genetic counselor or through an eHealth portal. Participants will complete surveys before and after receipt of results to understand patient experiences with these methods of education and return of results to determine if digital tools can be used to help ensure more patients get access to research results which could impact their health.

The Stroke Aetiology and VascuLar Disease in Stroke and TIA Study - A Clinical Study Analysing the Effects on Cardiovascular Health and Disease With an Extended Investigation Into Conditions Causative of Stroke and Concomitant Cardiovascular Disease in Patients Admitted for Acute Stroke or TIA
Annually, about 4000 Swedes suffer a recurrent stroke, and for many, their lives change dramatically. To prevent recurring strokes, knowledge about the individual's risk of recurrence is needed to tailor an effective preventive medical treatment. The purpose of the SALSA study is to investigate whether an expanded risk assessment and subsequent treatment can reduce the recurrence of stroke in study patients. Stroke, i.e., infarction/bleeding in the brain, has several different causes that individually or together constitute the risk of recurrence. Furthermore, stroke patients often have concomitant vascular diseases in other vascular beds, which further increases the risk. Every fourth patient with acute stroke or transient ischemic attack (TIA) admitted to any of the stroke wards at Danderyd Hospital, Stockholm, Sweden, is consecutively invited to participate in the SALSA study. Those who accept the study invitation, receive an expanded investigation of the most common causes of cerebral infarction (atherosclerosis, atrial fibrillation, narrowing of the brain\'s small vessels) or brain haemorrhage (presence of the protein amyloid in the vessels, high blood pressure). Due to the high risk of stroke patients having a vascular disease, such as atherosclerosis, the presence of arterial stiffness in the aorta, 24-hour blood pressure, and blood circulation in the legs are examined at the follow-up visit. If vascular disease is detected, expanded preventive treatment is provided. Neither a general investigation of the most common stroke aetiologies in addition to the one assessed to have caused the current stroke nor examinations of other vascular beds are recommended in national stroke guidelines. In addition to the extended risk assessment, the patient will get a written treatment program tailored after the individual patient's risk profile. The compliance to this treatment program will be assessed during a return visit one year after the hospital stay. After this visit, the active participation in the study is completed for the study participant. During the remainder of the follow-up, the study participant will be followed in national medical registers. The remaining 3/4 of patients at Danderyd Hospital constitute the comparison group, who are investigated and treated according to routine and hence do not undergo the additional vascular examinations. Stroke recurrence and other cardiovascular events occurring within the next 5-10 years will be compared between study patients and the comparison group via the national stroke registry containing all stroke and TIA patients at Danderyd Hospital.
