NCT06041581
Cardiovascular disease (CVD) is common, deadly, and costly, and adults with insomnia represent a large group of people at elevated risk of developing CVD in the future. This clinical trial will determine if our updated insomnia treatment, called the SHADES intervention, improves CVD factors thought to explain how insomnia promotes CVD and if these improvements are due to positive changes in sleep factors. A total of 200 primary care patients with insomnia and CVD risk factors will be randomized to 6 months of the SHADES intervention (internet, telephonic, and/or face-to-face cognitive-behavioral therapy for insomnia) or the active control condition (sleep education/hygiene, symptom monitoring, and primary care for insomnia). Before and after treatment, participants will complete measurements of the CVD factors (systemic inflammation, autonomic dysfunction, metabolic dysregulation, proinflammatory gene expression) and the sleep factors (insomnia symptoms, sleep onset latency, wake after sleep onset, sleep efficiency). Researchers will test whether the SHADES intervention produces greater improvements in the CVD factors than the active control condition.

NCT05379608
Aim of this prospective, interventional, single-center, randomized study is to evaluate the efficacy and safety of intermittent hypoxic-hyperoxic training (IHHT) as a rehabilitation method in patients with cardiovascular pathology in the early period after coronavirus infection. The study will include 60 patients with cardiovascular pathology who underwent confirmed by laboratory tests COVID-19 infection 1-3 months ago with the degree of lung lesion CT3, CT4, who were admitted to the University Clinical Hospital No. 4 of I.M. Sechenov First Moscow State Medical University. The patients will be divided into 2 groups (intervention and control groups). Intervention group will inhale hypoxic gas mixtures (10-12% O2) followed by exposure to a hyperoxic gas mixture with 30-35% O2 5 times a week for 3 weeks, while control group will undergo a simulated IHHT. All the patients will undergo identical laboratory and instrumental testing before IHHT, after the last IHHT procedure, in a month after the last IHHT procedure and in 6 months. Estimated result of the study is to confirm or refute the hypothesis of the study that a three-week course of IHHT in patients with cardiovascular pathology in the early period after coronavirus infection can improve exercise tolerance, as well as the quality of life and psychoemotional status, and affect the dynamics of laboratory and instrumental parameters.

NCT07059260
Heart failure (HF) is a growing public health problem, expected to increase in prevalence and incidence due to population aging. This challenge is compounded by the healthcare overload following the COVID-19 pandemic, particularly in primary care (PC). Early diagnosis of HF is critical for improving outcomes, reducing complications, and optimizing resource use. However, there is no robust scientific evidence supporting the effectiveness of early screening for HF in PC settings. This study aims to evaluate whether an early cardiology assessment model for patients with suspected HF and elevated NT-proBNP levels (\>300 pg/mL) improves clinical outcomes compared to the standard referral pathway. The hypothesis is that early intervention will reduce emergency visits, hospitalizations, and mortality related to HF. This is a prospective, single-center, open-label, phase II randomized controlled trial with parallel group allocation (1:1). Patients presenting to PC with HF symptoms and no prior HF diagnosis, who have NT-proBNP levels \>300 pg/mL, will be invited to participate. After informed consent, participants will be randomized to one of two groups: * Intervention group: Early cardiology assessment within 7 days. * Control group: Standard referral by PC physician per usual care. Randomization will be computer-generated and managed independently to ensure allocation concealment. Patients will be followed for 12 months from the date of NT-proBNP testing. Outcomes will be collected through both cardiology and PC visits. Our primary outcome measure will be the clinical benefit, defined as a hierarchical composite endpoint of: 1. Cardiovascular mortality 2. All-cause mortality 3. Number of hospitalizations due to HF 4. Number of urgent care visits due to HF 5. Number of GDMT (Guideline-Directed Medical Therapy) drugs initiated 6. Number of GDMT drugs with dose escalation 7. Proportional change in log (NT-proBNP) at 12 months The primary analysis will use a win ratio methodology to maximize statistical efficiency and clinical interpretability. Secondary outcomes include: * Each component of the primary endpoint * Stratified analysis by confirmed or excluded HF diagnosis * Stratified analysis by HF phenotype (HFrEF vs HFpEF) * Stratified analysis by sex A sample size of 304 patients (152 per group) has been calculated to detect a win ratio of 1.7 with 80% power, based on expected clinical benefit and statistical assumptions from prior literature. The study is expected to complete recruitment within 12 months, with a total study duration of 24 months including follow-up and data analysis.
NCT05910320

NCT02911337
The purpose of this study is to examine the efficacy of an intensive, supervised, lifestyle modification program on symptoms and signs of heart failure as well as laboratory and echocardiographic measures of cardiac structure and function. This will be a 6 month trial in 50 patients with a clinical diagnosis of heart failure with preserved ejection fraction (HFpEF). Patients will be enrolled in the Medical University of South Carolina weight management 15 week lifestyle change program which will involve weekly visits that rotate among the clinical specialities (dietary, exercise and behavioral) and scheduled visits with the research Registered Nurse. Each patients baseline data will be used as the control and compared with the same measurements at the 6 month end point.
NCT04217447
* Long-term aspirin (ASA) is the standard recommended antithrombotic therapy in patients with stable coronary artery disease (CAD), especially following stenting (Class I, Level A). * Long-term oral anticoagulation (OAC) is the standard antithrombotic therapy in patients with atrial fibrillation (AF) associated with one or more risk factor for stroke (Class I, Level A). * During the first year following acute coronary syndrome (ACS) and/or percutaneous coronary intervention (PCI), several studies evaluating the combination of OAC treatment and antiplatelet therapy are either already published or ongoing. * At distance of the index ACS and/or PCI, patients with stable CAD and concomitant AF remain at particular high-risk of ischemic (3 to 4 times higher as compared to patients with stable CAD without AF) and bleeding events. Antithrombotic management of these patients is subsequently highly challenging in clinical practice. The European task force suggests that the use of a full-dose anticoagulant monotherapy without any antiplatelet therapy should be the default strategy in such patients with both, AF and stable CAD. * However, evidences are sparse and weak to support such a strategy (only observational studies with many biases) and no randomized trial has assessed this question. These patients, especially those at high-risk of recurrent ischemic events (post- ACS, diabetes, multivessel CAD…) may benefit from the combination of OAC and aspirin at long-term. Indeed the crude event rate of ischemic events is much higher than the crude event rate of bleeding in this specific population. Ischemic events are 2 to 3 times more frequent than bleeding in daily practice. * The benefit/risk ratio of these two different strategies (ASA in combination with OAC vs. OAC alone) in patients at high-risk of recurrent coronary and vascular events remains unknown. Dual therapy with full-dose anticoagulation and ASA may lead to higher risk of major bleeding, while stopping ASA in stabilized high-risk patients after PCI may lead to poorer outcome regarding ischemic events. * The coordinating investigators therefore designed a double blind placebo controlled trial in order to assess the optimal antithrombotic regimen that should be pursued long-life in this subset of patients.
NCT06212466
A prospective, multicenter, observational, single-arm trial to validate CardioFlux MCG's ability to diagnose myocardial ischemia caused by coronary microvascular dysfunction in patients with suspected ischemia and confirmed no obstructive coronary artery disease (suspected INOCA) by using diagnostic measures of coronary flow reserve (CFR) via invasive angiography as a reference standard for diagnosis.

NCT04180696
The Mid-Q Response study is a prospective, multi-center, randomized controlled, interventional, single-blinded, post-market study. The purpose of the Mid-Q Response study is to test the hypothesis that the AdaptivCRT (aCRT) algorithm is superior to standard CRT therapy regarding patient outcomes in CRT indicated patients with moderate QRS duration, preserved atrioventricular (AV) conduction and left bundle branch block (LBBB). The study will be executed at approximately 60 centers in Asia. The subjects will be randomly assigned in a 1:1 ratio to the aCRT ON (Adaptive Bi-V and LV) group or the aCRT OFF (Nonadaptive CRT) group. The primary objective is to test the hypothesis that aCRT ON increases the proportion of patients that improve on the Clinical Composite Score (CCS) compared to aCRT OFF at 6 months of follow-up.
NCT07055347
This single-arm feasibility study will pilot a home-based cardiac rehabilitation program for preschool children (aged 3 to 7 years) who have undergone corrective surgery for congenital heart disease. Following the development of the program through expert consensus, this phase will implement the preliminary version of the program in a selected sample of caregiver-child pairs over a 12-week period. The study will assess feasibility by evaluating caregiver adherence to the intervention, acceptability of the program components, and completeness of rehabilitation task records. Descriptive data on safety, participation rate, and delivery logistics will also be collected. Findings will inform refinement of the program prior to future effectiveness testing.
NCT05928026
The goal of this clinical trial is to test whether financial support in the form of a one-time $500 stipend would improve medication adherence and quality of life in low-income, socially-needy patients with heart failure with reduced ejection fraction in the post-discharge setting. The main questions it aims to answer are: * Will financial support improve heart failure quality of life? * Will financial support improve medication adherence? Participants will complete surveys on quality of life, social stress, and spending habits at their baseline visit. Participants will be randomly assigned to receive $500 at their baseline visit or $0 at their baseline visit. At their one month visit, quality of life and medication adherence will be assessed. These results will be compared between groups. The group that received $0 at their baseline visit will be provided $500 at their one-month visit and return for a two-month visit. At that visit, quality of life and medication adherence will be assessed. These results will be compared to their one-month results. Researchers will compare the 1-month quality of life scores and medication adherence scores between the immediate financial support vs delayed financial support. Researchers will also compare 1-month vs 2-month quality of life and adherence data for participants who were randomized to the delayed financial support group.
NCT06576297
In a randomized controlled trial, to study the utility of inspiratory muscle training (IMT) to improve functional outcomes in adults aged ≥70 years with heart failure (HF) who have been referred to palliative care for end-stage HF management. * The study team hypothesize that older HF patients will be able to use IMT safely, reliably, and effectively in a 12-week home-based training regimen. * The study team hypothesize that physical function (sit to stand, gait speed, grip strength), respiratory/pulmonary function, self-efficacy, fatigue and quality of life will increase among older HF patients randomized IMT versus those randomized to usual care.
NCT06967389
The goal of this clinical trial is to learn if the drug semaglutide changes markers of disease risk as it relates to weight in children ages 12-15 years old who are obese (class 2 or 3). The main questions it aims to answer are: * How do the rate of weight loss, body mass index (BMI), body composition, heart structure and function, and exercise ability interact with one another in the study population at enrollment? * How do risk markers of disease change over the study in the study participants who are given semaglutides to help with weight loss? * Are there differences in the above factors between males and females and are there key factors to help improve the outcomes? Participants will be given semaglutide for this study. During the course of the study, participants will: * have two cardiac MRI scans OR two cardiac echocardiograms (one before starting semaglutide and one around 12 months after taking the drug) * have body composition and fitness levels assessed twice (before semaglutide and around 12 months after taking it) and have urine specific gravity (USG) measured * have extra blood drawn when labs their doctor orders are already being drawn (once at the beginning of the study, once around 6 months after enrollment, and once at the end of the study) * have follow up visits with the study doctor * be asked to take a pregnancy test if they are female and have started menstruation
